The method of fighting fires on peatlands (options), threshold (options)

 

The invention relates to extinguish fires by limiting the possibility of spread and fire-extinguishing apparatus, and in particular to methods of creating a barrage of obstacles to the movement of the fire in the thickness of the peat bog and the means for its implementation. The objective of the invention is to develop options for mobile how to fight fires on the basis of the formation of the protective barrier and the creation of designs reusable protective barriers for the implementation of these methods. Improving the reliability of preventing the spread of fires, reducing the likelihood of passage of fire through the barrier the barrier, the relatively high speed of installation protective barrier, the adaptability of the method of construction of the barrier is made possible by the fact that the two declared variants of the methods of fighting fires on peatlands and protective barriers are based on the use for the purposes of fighting fires three elements: the trench, usually constructed parallel to the front of the fire, the barrage of obstacles and liquid fire extinguishing agent as an element included in the protective barrier, which is poured or low permeability capacity, formed between the side plates and founded the tubes of heat-sensitive material with a melting point not lower than 100oWith, or in the second embodiment, in the protective capacity of fire-resistant material, facing the front of the fire and mounted on a slab of concrete. The height of the slabs of reinforced concrete when it exceeds the height of the trench, and the liquid extinguishing agent performs the basic function of fire fighting and protective - protects the slab of concrete from overheating and destruction. 4 S. and 2 C. p.

The invention relates to the field of extinguishing fires by limiting the possibility of spread and fire-extinguishing apparatus, and in particular to methods of creating a barrage of obstacles to the movement of the fire in the thickness of the peat bog and the means for its implementation.

It is known that the technology of fighting fires on peatlands has its specificity, and the fires can be classified as spatial developed. This is due to the nature of the combustion of peat, which is burning in the depth interval from the surface to the mineralized Foundation or to the aquifer on average from 0 to 3.5 m the burning Rate and direction of fire fronts do not always depend on the direction and speed of wind. Due to the different density of the peat, its heterogeneity and various oxygenated last burn unevenly and much of the fire is not always eliminate these languages, that reduces the degree of efficiency of fire.

The special relevance of this issue has acquired in connection with the state policy of draining peatlands, leading to disruption of the natural balance of ecosystems and gave rise to the emergence of artificial fire hazardous areas.

The specificity of peatlands and determines the approach to the solution of the problem, and it is not only the fire, but, first and foremost, prevent its spread by creating protective barriers, this issue is relevant for localization of vegetation fires. For example, the famous "Method of localization vegetation fire, including the formation of a protective barrier of non-combustible material, one edge of which bury into the soil to a depth of burn-out, with threshold set at an angle 70-30owith respect to the plane of the earth surface from the side of the fire and annealed vegetation from the restrictive barrier in the direction of the fire without extinguishing the back side, and the protective barrier created on the height, the greater the average flame height is less than or equal to the maximum height of the flame on the fire edge [ed.St. SU 1233875, 30.05.86, bull. 20].

The disadvantage of known the burning peat is up to several meters and the implementation of the method for these purposes becomes impossible or extremely expensive.

To stop the spread of fires on peatlands known method of construction of firebreaks in the form of a ditch with a depth to the mineral layer or groundwater level, implemented by the device for laying fire lanes on peatlands, having a hinged connection with the dumps and acryli with shares on author.St. 1542549 by layer-by-layer offset peat outside firebreaks. The use of the proposed device allows to reduce the energy intensity of creation of a protective ditch, that is, to perform its larger cross-section than in the application of plough-wheel ditchers previous generation [ed.St. SU 1542594, 15.02.90, bull. 6].

The disadvantages of the described method include the fact that not considered specific combustion drained peatlands.

Similar technical result is achieved by way of localization and local fire involving the lining of mineralized barrier strip formed by the removal from the surface of the ground moss-lichen cover and subsequent cover of mineral soil on paved strip previously unselected layer of moss cover, with mineralized barrier strip formed by cutting in the soil drainage is meganium edges of the drainage slots [U.S. Pat. EN 2170119, 10.07.01, bull. 19].

The disadvantage of this method is the need for a large amount of earthworks to obtain reliable enough rumble strips, but that does not protect the opposite fire wall drainage slit from its ignition at relatively close to the fire.

There is also known a method of extinguishing peat fire, according to which conduct vehicle offset layer burning peat with capture depth is not yet burning peat in a spiral from the periphery to the center, and then in a spiral from the center to the periphery, it is necessary to capture the depth of peat, yet not burning, amounted to 80-100% of the depth of peat burning. In the second phase offset peat components comprising after the first stage of the quenching of smoldering in places peat to peat, raised from the combustion zone, there is an additional mixing peat with capture depth of peat, yet not burning, comprising 40-50% of the original depth [ed.St. SU 1591999, 15.09.90, bull. 34].

As disadvantages of this method can be called a large amount of work by loosening and displacement of the peat. In addition, mixing not burned peat with a blown reduces EEA can be deep, in this case, this method is generally not applicable.

There is also known a method of fighting fires on peatlands by the construction of the trench to the depth of the peat deposits or to groundwater levels, bookmarks in her fire-extinguishing agent simultaneously with the filling of the trench mineral soil. When burning peat fire, approaching the slope of the protective strip to initiate the action of the fire extinguishing agent. Fire extinguishing agent penetrates into the adjacent layer of peat is sprayed over him and lowers the intensity of the combustion. In the case of penetration of fire or smoldering peat crumb behind a strip of fencing activated fire extinguishing agent is incorporated in an opposite slope, stopping the burning of peat. [ed.St. SU 1297875, 23.03.87, bull. 31].

The disadvantage of this method is the large amount of mineral soil necessary to create a protective barrier, low efficiency of fire extinguishing agent and large losses, because the combustion is not around the contour of the protective barrier, but only in some places. Repeated use of this agent is almost impossible.

Thus, all considered analogues of the previous generation are not fully solve the problem of war

The closest and selected as the prototype for the method of fighting fires on peatlands and for defensive barrier are protective barrier on author.St. SU 869779 and method of extinguishing a fire, implemented with it. The method includes creating a protective barrier in the form of a trench at the depth of the peat prior to the occurrence of the mineral layer or groundwater levels. In the trench form a protective barrier to prevent the spread of fire by filling mineral soil [ed.St. SU 869779, 07.10.81, bull. 37].

The disadvantages of the prototype can be attributed the comparative duration of manufacturing protective barrier associated with the need for production and delivery of large amounts of mineral soil, the stationarity of the created earth structures and occasional use of mineral soil.

The objective of the invention is to develop options for mobile how to fight fires on peatlands on the basis of forming a protective barrier and creating designs, reusable protective barriers for the implementation of these methods.

Technical results that can be obtained with the implementation of the proposed methods (options) dlsa: - improving the reliability of preventing the spread of fires; - reduced transition probabilities of fire through the barrier the barrier; - the relatively high speed of installation protective barrier; - reusable protective barrier; adaptability of the method of construction of the barrier.

The solution of the stated problem and achieve the above results became possible due to the fact that in the known method of fighting fires on peatlands in the first embodiment, including the construction of the trench at the depth of the peat to mineral layer or aquifer, formation and placement in her barrage of spatial barriers, the barrier is formed from at least two pairs of plates, one of which has a through hole and provided with caps on the number of these holes of the heat-sensitive material with a melting point of not less than 100oWith plate height exceeding the depth of the trench, and at least two substructures, each in the form of an elongated rectangle with length equal to the length of the base plates, and a width, the smaller the width of the trench, made of reinforced concrete, while supporting base is fixed by at least two flexible connections with the base formed on the bottom of the trench, and the base plate on which is fixed a supporting base, based on this reference base on the bottom of the trench, at the top of this stove is based on the edge wall of the trench, following in the row plate with support base set similarly and butt with the first pair, and the other plate being installed with the emphasis in the support base and the edge of the corresponding wall of the trench, forming between all elements of reinforced concrete liquid fire extinguishing agent, having a cross section in the form of an inverted base up the line, while the plate with through holes, closed tubes, install from the front of the fire, all the plates, placed in the same row, is fixed rigidly to each other, and the other plate is fixed adjustable rigid link, location contact plates are isolated and fill the resulting capacity of the liquid extinguishing agent.

Similarly, the solution of the stated problem and the achievement of the above results for the second option made possible by the fact that in the known method, including the construction of the trench at the depth of the peat to mineral layer or aquifer, formation and placement in her barrage of spatial barriers in the form of walls, the tyk among themselves, as part of prefabricated elements impose a slab of concrete with a height exceeding the depth of the trench, which is fixed with a horizontal offset in the direction of extension of the wall of the protective capacity of fire-resistant material, the area of the side surfaces of which are directed toward the slab of concrete, commensurate with the lateral surface of this plate with the possibility of joining the ends of the protective capacity with the ends of the protective capacity of adjacent modular element, with prefabricated elements installed in a trench alternately and thus that the protective liquid extinguishing agent pay towards the front of the fire, prefabricated element deviate from the vertical axis of the trench and rest on the bottom and the top edge of the trench opposite the fire, and protective capacity of fire-resistant material is poured liquid fire extinguishing agent.

The implementation of both variants of the methods of fighting fires on peatlands and achieving the above results became possible for the first variant protective barrier due to the fact that in the known protective barrier in the form of spatial barriers to fire from fire-resistant material placed in the trench, the depth of which is equal glubinah pairs of opposite side plates and the support base, made of reinforced concrete, with concrete side plates have a height exceeding the depth of the trench, installed on the supporting base on the bottom of the trench corresponding to each plate, and rejected relative to the vertical axis of the protective barrier in opposite directions at an angle not exceeding 45owith education between liquid fire-extinguishing agent having in cross section the shape of an inverted base up the line, the supporting base is made in the form of an elongated rectangle whose width less than the width of the trench, and the length equal to the length of the base plate of reinforced concrete and provided with at least two flexible connections for attachment to the base of one of the side plates of reinforced concrete with a length of flexible connection that allows you to make reference to the basis in the trench horizontal or near horizontal position. Slabs of concrete, located in the same lateral plane, drawn up between the butt and firmly fastened, the other slabs are interconnected in the upper part of the rigid adjustable link with the ability to prevent their rotation relative to the base. Plate facing the front of the fire, fitted kwasny what I at least 100oC.

In the preferred case execution protective barrier it is further provided with at least one internal transverse baffle installed with an emphasis in opposite plates of reinforced concrete and anchor the base of reinforced concrete tanks for liquid fire extinguishing agent can be divided on the last cavity.

As for the second option, this problem is solved due to the fact that defensive barrier in the form of spatial barriers to fire from fire-resistant material placed in the trench, the depth of which is equal to the depth of the deposits of peat to mineral Foundation or to the depth of the aquifer, the barrier to fire collected in the form of a continuous wall of the constituent elements, with the element height exceeding the depth of the trench, and a thickness less than the width of the trench, and its deviation from the vertical axis of the protective barrier on the corner, providing it support to the edge of the bottom of the trench from the fire edge and the upper edge of the trench on the opposite side, and the composite wall element includes a solid slab of concrete and protective capacity of fire-resistant material for liquid extinguishing agent to the area of the side surface, and attached to it with a horizontal offset relative to the edge of the plate toward the building wall, with the possibility of joining the ends of the protective capacity with end faces similar protective capacity in the field of solid side plates of reinforced concrete adjacent member, a wall made of prefabricated elements in the trench facing the protective capacity of the front line of fire.

In the preferred case of execution of a component element of the protective barrier is further provided with a visor facing the fire, which is attached to the upper edge of this element.

Declare a set of essential features methods and devices for both variants is not known in the prior art and allows, in contrast to analogues, to create two variants of non-standard ways of fighting fires on peatlands and implement them accordingly two options collapsible protective barrier of repeated use, which prevents it from binding to the fields of natural fire-resistant materials and allows, on demand, to quickly mount barrier barrier at the site of the proposed approach the front of the fire.

Both methods of extinguishing a fire in peatlands and protective barriers are based on the use for the purposes of fire fighting three main elements: the trench, usually constructed is of amenta, included in the protective barrier, which is poured or low permeability capacity formed between the side plates and the base of the concrete, or in a protective capacity of fire-resistant material, for example metal, mounted on a slab of concrete. In both cases, the side movement of the front fire movable liquid extinguishing agent is consumed during the fire and its volume must be replenished. The need to create a permeable liquid extinguishing agent due to the fact that the mere penetration of the agent into the trench, built in peat leads to the fact that he goes into the peat, and not kept in the trench. The second function performed by the liquid extinguishing agent included in the composition of the protective barrier, is the protection of slabs of concrete from overheating and destruction, as at a temperature of 300-350oWith the concrete begins to crumble.

In the first embodiment, this function is realized through the use of the composition of the protective barrier from the front of the fire slab of concrete, which is a through hole. In the initial period of time these openings are closed tubes of heat-sensitive reinforced concrete tank is heated and boils, tube melt, and he poured jets through the holes, wetting the plate and peat.

According to the second variant of the protective function of liquid fire extinguishing agent in the protective capacity of fire-resistant material, also facing the front of the fire. When the heat from the burning peat liquid fire extinguishing agent boils, and protect concrete slab heating temperature will not exceed 100oC.

To create a protective barrier for the claimed variants you can use as plates of standard concrete slabs, for example, size 4,2x1,5 m by lowering the latter into the trench crane.

After burnout of the protected area and filling the trench with a mixture of ash with liquid fire extinguishing agent of the plate is recovered and used again in the same lateral plane slab of concrete and connect the quick-release bolts.

As a liquid fire extinguishing agent may be used water. Supply protective barrier in the first embodiment in the preferred case, the execution of the internal transverse dividing partitions allows you to divide the total capacity of the cavity for the liquid extinguishing agent isolated from each other Usami agent is retained in the sealed cavities.

Supply protective barrier according to the second variant in the preferred case execution visor, directed at an angle toward the front of the fire, contributes to the damping of sparks and allows the use of pairs of containers from fire resistant material and direct it at an angle in the direction of the fire.

The invention is illustrated by the following figure.

Threshold in the first embodiment is a trench 1 on the depth of the aquifer or depth of peat 2 to mineral layer 3, parallel to the front of the fire 4. In trench 1 at the side opposite frontopolar front of the fire. The base of each of these plates 5 and 6 by using flexible connections 8 and 9 (when attaching to the plate 5) is suspended from the support base 10, and 11, each in the form of an elongated rectangle with length equal to the length of the base, for example, plate 5. The supporting base 10, similarly, can be fixed on the opposite plate 12, which, as all the plates in this series, has a through hole 13 and the tube 14 by the number of through holes 13 of the heat-sensitive material with a melting point of not less than 100oC. In the case of mounting the support base on the plates 5, 6, and further, the plate 12 and the subsequent plates in this series based on the supporting base, such as 10, and the upper edge 15 of the wall of trench 1, facing the front of the fire 4. Capacity 16 liquid fire extinguishing agent 17 has a cross section in the form of an inverted base up the line.

Slabs of concrete in the respective rows are connected back to back and rigidly fastened in a known manner, for example, by bolts 18, the respective plates of the other series are hard adjustable connection 19. Protective barrier with insulation 20 contact plates.

In the preferred case, the performance threshold is equipped with at least one vnutridnevnye, for example 10, liquid fire extinguishing agent 16 can be divided on the last cavity.

Method of extinguishing a fire in the first embodiment using the described protective barrier is as follows.

Build a trench 1 with barrani machine or rotary excavator (not shown) at the depth of the peat 2 to mineral layer 3. Trench 1 constructed parallel to the front of the fire 4. In an open trench 1 crane (not shown) is lowered from the side opposite to the fire edge 4, with emphasis in the edge wall 7 of the trench 1, a slab of reinforced concrete 5. With the base plate 5 is lowered into the trench of the supporting base 10, is bonded with the plate 5 by flexible connections 8 and 9, so that when establishing this base 10 at the bottom of the trench 1 plate 5 will rely on its upper surface. Other plates, such as 6, in the row set similarly to the plate 5 plate on the lateral edges of the plates 5, 6 of reinforced concrete. The other plate, for example, 12 are provided with a through-hole 13, which before descending into the trench closed tubes 14 of a thermoplastic material with a melting point of not less than 100oWith, put them alternatively in trench 1 and sets with a focus on fitness is ransei 1, facing the front of the movement of fire 4. All slabs of reinforced concrete, such as 5, 6, 12, and substructure (for example 10) are capacity 16 liquid fire extinguishing agent 17 with a cross-section in the form of an upside-base line. Slabs of concrete in the same row connected back to back and rigidly fastened to each other, for example by bolts 18. Respective opposite plate, for example 5 and 12 are clamped between a rigid adjustable connection 19. Isolate the parts of the plates, for example, are cool insulation 20, and fill up the tank 16 liquid fire extinguishing agent 17, for example water.

When approaching the front of the fire to the trench 1 tube 14 of heat-sensitive material melt and open the through hole 13, for example, in the plate 12 of reinforced concrete. Water 17 flows through the holes 13 streams, moistening the plate and wetting the peat. In the process of fire extinguishing water 17 from the tank 16 evaporates and it topped up, maintaining the initial level.

Protective barrier on the second version made in the form of spatial barriers to fire from fire-resistant material (see Fig.4, 5, 6, 7), located in the trench 21. This barrier is collected in the form of a solid wall of constituent elements 22 with the height of the composite elements is through the axis of the protective barrier on the corner, providing it support to the lower edge 23 of the bottom of the trench from the fire edge and the upper edge 24 of the trench 21 on the side opposite the fire. An integral element 22 is a solid plate 25 made of reinforced concrete, in which one of the known methods attached protective container 26 from heat resistant material, such as metal, for liquid extinguishing agent 27. The tank 26 is set so that it is displaced horizontally relative to the concrete slab 25 element 22 on which it is fixed at the side of the building wall with the possibility of joining the ends of the protective capacity of 26 one element with the ends of the protective capacity of the adjacent element in the area of the end surface of the plate 28 made of reinforced concrete.

The area of the side surface of the protective container 26 in line with or corresponds to a square plate 25 made of reinforced concrete. From the spontaneous loss of the elements of the protective barrier plate of reinforced concrete connected by fasteners (not shown). The offset of the protective capacity 26 relative to the plate 25 of the concrete in the direction of extension of the wall provides overlapping joints in slabs of reinforced concrete and prevent the penetration of fire through these walls. Part of the protective barrier ledge the flight of sparks through the protective barrier of the latter in a preferred embodiment, is equipped with a special solid or mesh visor 29, pinned at the top of the precast element, for example, by means of the bracket 30.

Using the proposed protective barrier on the second version was implemented method of extinguishing a fire in peatlands, which is as follows.

Out with the help of an excavator barrani machine (not shown) trench 21 to the depth of peat to mineral layer. With the help of a crane (not shown) is lowered in this trench plate 25 made of reinforced concrete, which reinforce the protective container 26 from heat resistant material, for example metal, offset horizontally relative to the slab of concrete, with emphasis in the edge of the bottom 23 of the trench 21 by the fire edge and the upper edge 24 of this trench from the side opposite to the front of the fire. Connect the butt plate of reinforced concrete and the ends of the respective protective containers. Due to the excess height of the composite element 22 depth of the trench 21 last protrudes above the surface, additional restraining surface fire. Protective container 26 through the area of its lateral surface, close or equal to the area of the plate 22 made of reinforced concrete, closes the latter from the fire and prevents it from overheating. The constituent elements of the set in a protective capacity 26 store with the emer water. When approaching a fire to the compound element 22 of the liquid extinguishing agent in the vessel begins to heat, and then simmer. This process takes a huge amount of heat, but the temperature of the heating plates of reinforced concrete will not exceed 100oWith and, therefore, this plate will not collapse and will remain reusable.

In a preferred example of the way on the outer edge of the precast element is fixed removable visor 29 (solid or mesh) in the form of the angular plane directed in the direction of the front of the fire, contributing to the suppression of sparks. The steam released during boiling of liquid fire extinguishing agent in the protective container 26, captured and sent in the direction of a moving fire fronts to moisten the peat. On boiling extinguishing agent or water are wasted an enormous amount of heat. The fire itself is extinguished. In the case of intense boiling in the process of extinguishing liquid agent into the tank can be topped up.

The practical applicability of both methods of extinguishing fires on peatlands following examples show.

Example 1. (Model experience for the first option).

In the capacity of fire-resistant material, in which the selected metal is falling with a lid and put under load (1000 pieces of bricks or 4 tons). Under this load of peat incubated for about 30 days. During this time, the peat is compacted and deposited on 10 see then in the center of the layout artificial turf fields manually construct a trench from one side to the opposite side tanks width 400 mm in parallel to the intended front of the fire movement. Fix by means of flexible links in chains on the basis of a solid slab of concrete support Foundation, whose length is equal to the length of the base plate, and the width is half the width of the trench. Put the plate with its support base in the trench so that the supporting base rests on the bottom horizontally, and in its upper surface rests slab of concrete, at the top of this plate rests on the edge of the wall of the trench, opposite the front of the fire movement. The angle of deflection of this plate from the vertical is 30o. Similarly, with emphasis on the upper surface of the support base, but only with a deviation to the wall of the trench facing the front of the fire movement, set a slab of reinforced concrete, which is a through hole, closed tubes of heat-sensitive material with a melting point not lower than 100oWith, for example hollow plastic popolniaut formed container with water. Cross-section of the water tank is an inverted base up the line, close to equilateral. Peat formation on fire with a blowtorch through the side wall of the metal container, parallel to the trench. An hour later, the fire is coming to the protective barrier (the burning speed is about 1 m/h). The water warms up and begins to boil. Tube 4 of the upper ranks of the melt, opening the openings through which the water with the steam jets out, wetting the burning peat. Ten minutes peat goes out. Water consumption is 50%. The temperature of the heating plate with through holes 100oC.

Example 2. (Model experience for the second variant of the method).

For example, 1.

On the slab of concrete attached with screws capacity of metal.

Received prefabricated element is lowered at an angle in the trench slab of concrete wall, opposite the front of the fire, secure the visor. Pour into a container made of metal, to the edges of the liquid extinguishing agent in the form of water. With the approach of the fire barrier to the barrier according to the second variant, the water in the tank from metal heats up and begins to boil. The fire is slowly dying down. During experiment has boiled away 1/3 of the water is in the tank. The opposite of the spine experiences within the examples carried out three times. We obtained the similar results.

As can be seen from examples 1 and 2, the claimed set of essential features for both methods of extinguishing a fire in peatlands and protective barriers can solve the problem and achieve such technical results as improving the reliability of preventing the spread of fires, reducing the likelihood of passage of fire through the barrier the barrier, the relatively high speed of installation protective barrier, reusable protective barrier, the adaptability of the method of construction of the barrier.

Arsenal fire extinguishing tools were added to the original protective barriers, implementing new ways of fighting fires on peatlands.
