The invention relates to the field of land reclamation and can be used for flushing of sediment in subsurface drainage systems.

Known reclamation system, equipped promino-vakuumiruemye nozzles installed in the interface nodes drains with pressure distribution pipelines is directly behind the non-return valves, wherein the lower end of each pipe communicated with distribution piping and drains, and the top displayed on the surface of the earth and provided with an airtight lid (Patent RU 2022098, CL E02B 11/00, 1994).

The disadvantage of this system is that after the end of each irrigation water is useless is discharged outside the array of reclaimed, the flushing process is slow, as the rate of flow from the pipeline is insufficient to intensive erosion of the sediment. In addition, the system requires the length of the pipeline numerous pockets-traps for the deposition of large sediment that increases the cost of construction of such a system, it causes considerable local resistance to the movement of water along the pipeline and at the end of the rate of flow of water can be reduced below the calculated, resulting in the transport capacity of the drainage effluent from drains is sharply reduced. Another disadvantage is that the area of application, for example, under pressure from the flexible hose Ogre�Nicene point the way on a short section of pipe, without affecting the entire length of the pipe to the mouth, where the prism sediment deposits increases significantly.

Also known drainage system that includes a collector connected to the drains emptying into it, and observation wells in the ground connection of drains with the sewers drains and the sources are established connections with ferromagnitnymi plugs and attached flexible filaments arranged in the cavity drains and collector, with drains connected to the manifold through the nozzles (Patent BY 8089, CL E02B 11/00, 2004).

The disadvantage of this system is the low reliability and durability of flexible strands, as, although they should have sufficient strength in the groundwater environment, however, their frequent pulling requires special skills and manual effort on both sides, large towing loads on the thread, its abrasion when working with sediment. In addition, it requires frequent visual observation or application of additional costs for determining the blockage of drains, which also raises the cost of the whole system, especially when there is a great length and the number of drains and a large enough number of them to the array. In this case, the lifetime is also reduced due to the increasing tensile stresses in the material of the filaments by each hand pulling the seals of sediment due mnogokrat�th pulling thread. In addition, there are complex and complicated and require large water heads, which leads to disruption of drainage pipe joints.

Another disadvantage is that over time the bandwidth drains can dramatically decrease. The reason is the formation on the inner surface of pipes of various deposits, the formation of which is due to the continued absence of drain cleaning. All this increases the hydraulic resistance of 2 times or more (operating under long-term) and cause excessive head losses.

The object of the invention is to increase the efficiency of cleaning and extend drainage by exposure to air on deposits.

This object is achieved in that the drain system including a collector connected to the empty drains, pipes and ushing of sediment, the flushing device is made perforated tubing in the form of vents, drains placed inside, fixed to the top of the pipe above the bottom, with the initial portion of the allotment in the form of a metal stem placed in the pipe and connected to a source of compressed air supplied short-compressor connected to the relay, wherein the duct is coupled with the receiver through a pressure hose.

Cu�IU, perforated tube along the entire length of drains is made of smaller diameter relative to the inner diameter of the drains.

This embodiment of the drainage system allows for comparison with the prototype to automate the process of protection of drain pipes by flushing the cavity from sediment and other impurities deposited on the walls of pipes, blurring across the length and the cross section of flow of the compressed air discharged through the perforated openings of the tubes connected to the compressor after a specified period of time. This interval is set by the operating conditions. The destruction of the sediments, expressed by the length of the pipe, team relay time is short compressor accumulated compressed air in the receiver for admission of air along the entire length of the perforated tube and entering it into the drains, where the air is mixed with water, causing the wave phenomena along the length of the drains, and increasing the speed of movement of suspended particles, and also due to the fact that these deposits still pretty loose, fragile and grip them with the walls of drainage pipes slightly. Reduces the flushing of sediments and different impurities. The inner walls of the tubing are washed and filled with an elastic medium is air, which is mixed with water. A jet of air out of the holes of the perforated tube with the most advanced technology� pressure (speed) and continue to erode as sediment, and wash the inside wall of the pipe drains, sediments are removed by significantly increasing the speed of water movement throughout the length of the drains to the sewer, next, in the open channel. The ability of compressed air does not allow the particles to settle to the bottom and along the length of the pipeline to a large extent. Compressed air from the compressor is supplied from the duct and further to perforated tubes attached to the upper part of the cavity of the pipe (arch pipe drains), i.e. above the bottom, which allows not only to wash the cross-section of the inner walls of the pipe, but also makes it possible to flush with the bottom sediments, the active resuspension, the rise of the sediment.

The free space in the cross section of the pipe allows you to float freely washed off the particles and together with the stream of saturated air, they go into the manifold and then into the open channel. Here there is no traction device for washing the sediment with no open manholes, which allows the wash water with the dissolved air to come out directly through the collector in the open channel, wherein the bandwidth of drains remains set to the original calculation.

The proposed device allows, without the high cost at the same time during the construction of drains on the array of drainage Provo�'it fastening perforated tubes inside the cavity drains and attach them above the bottom of the tubes. Therefore, immediately after construction enables in many cases to exclude from the technology of works on the drainage time consuming and inefficient operation for laying flexible strands and securing the ends of the pipes.

In addition, the increased reliability of tubes of polyethylene and other flexible tubes used in modern manufacturing technologies in the industry, allows you to make a broad selection of flexible along the length of the tubes. They can be manufactured in factory workshops in the pipeline for pulling in special machines. This in turn allows the mass manufacture of such perforated tubes with caps of fastening of the connections between them during construction. Service life at least 50 years. Reduced losses of water for rinsing and increases the productivity of the personnel on the drainage system. Thus, the impetus for leaching is not from the device controlling the differential water levels in the device, and from the time relay comprising a compressor for flushing the drains with compressed air briefly with the subsequent action of mixing with water.

The possibilities of this system is not limited, since the device along the length of perforated tube attached above the bottom in the cavity drains, has virtually no hydraulic resistance to flow and reduces the throughput�beard thread saturated with sediment when water moves in the direction of the manifold, next to the outdoor channel.

Economic effectiveness of the proposed drainage system is to combine in a single technological cycle of optimal water flow for flushing the drains and the manifold under pressure, optionally transporting the sediment under the pressure of compressed air, dissolved in water, as the length header is missing numerous open resource manholes that interfere with mechanized tillage during agricultural work.

Comparative analysis of proposed technical solutions and prototype shows that the claimed combination of features part of essential features is new, therefore, the claimed solution differs from the prototype and meets the criterion of "substantial differences".

Fig.1 is a diagram of the drainage system in plan; Fig.2 - a section a-A in Fig.1, the cross section of drains, manifold and pipe.

In all the figures the direction of the movement of water and air is shown by arrows.

The drainage system includes a collector-a collector of 1 connected with 2 drains. Vertical pipes 3 equip all origins 2 drains in the construction of a drainage network. At the same time inside the cavity drains 2 fix (fix) perforated �felling 4 small cross-section, which can be done by various methods of manufacture.

The tightness of the slots of the vertical pipe below the plow layer 3 is provided with a lid 5, which features a metal barrel 6. The lower end of the metal barrel 6 is rigidly connected to the perforated pipe 4, which has the air outlet 7 on the perimeter in a staggered manner, and the upper end by means of a flexible hose 8, the inlet of which is connected to the outlet 9 with a valve 10 and a receiver 11, a source of compressed air, the compressor (K) 12, connected to a time relay (R) 13 (relay not shown). Pressure hose 8 composite construction consisting of individual links of predetermined length between drains, provided with valves 14, 15. Hose coupling, metal barrel and the tube is made watertight, releasable connecting valve 16, for example, by clamps. In the end drains (mouth) made of the outlet opening 17, which is used to supply water to the collector-gatherer 1. The end walls of the metal of the barrel 6 are closed by the tube 18 and the end walls are not brought to the surface of the earth, since in this case they are damaged or destroyed in the process of mechanized tillage when hoeing and ploughing. They are opened only when necessary flushing of drainage from the collector and output flow with nano�AMI in the open channel 17.

The number of simultaneously wash drains 2 is determined by the accumulated volume of compressed air in the receiver 11 that is associated with the compressor 12, with auto switch time relay 13. In the receiver 11 are installed measuring instruments pressure (not shown). Moreover, the consumption of compressed air depends on the design of the perforated tube 4, its diameter, working length, size of air outlets 7, their frequency of placement along the length of the tube 4. Thus, all the dimensions are determined by calculation in the design process drainage system.

Flushing of the drainage system is as follows.

Install compressor system 12 and the receiver 11, which has in its set of flexible pressure hose 8 required length and stack it along the row of vertical tubes 3, knowing their location in the origins of drains 2. The beginning of the hose 8 is attached to the pipe 9 with the valve 10 of the receiver 11, and the end or fork is connected with a metal barrel 6 on the cover 5 of the nozzle 3 and is hermetically fixed by tightening the connected valve 16.

After performing these operations supply compressed air from the receiver 11 and by means of valves 10, 14, 15 set the number of concurrent drains to rinse depending on the accumulated volume of air in the receiver 11, to�which can be filled simultaneously by the compressor 12 team time relay 13 in the automatic operation mode signal, coming from instruments installed on the receiver 11 (not shown for simplification). In this case, the escaping air from the holes 7 perforated tube 4 has a disturbing effect on the flow of water in drena 2, sediments actively vspuchivajutsja and come in suspended their state, then they are carried away by water flow. As a result, improved transportation roiled particles, and previously precipitated ferrous compounds on the inner surface of the pipe is also washed with a significant increase in the rate of water movement in a closed reservoir 1, which is then transported in an open channel 17.

After washing the drains of the first group rinses second, third, etc. groups until, until you have washed all the drains are connected to this manifold. As a result of such exposure, the intensive mixing and transportation of sediment, and creates forward movement on their drena 1, which allows us to provide samopomich all drains and connections with the increased velocity of the water throughout the length of the drains, i.e., from its source to its mouth.

After performing these operations, turn off the receiver 11, the compressor 12 and move to a new position in the case of the limited length of the pressure hose 8 composed of separate sections along the length.

The system also allows the production�you combined method, i.e. to fill, for example, compressed air in the soil pores and thus create aeration in the soil.

Drainage system allows without large expenditures of labor and resources to carry out regular flushing of subsurface drainage several times a year in large areas immediately after construction and during prolonged use, allowing in many cases to reduce of technology the number of manholes and the connecting elements, to improve conditions of water flow in the drains. Eliminates the time consuming work in the operation of flexible filaments for pulling in the header and in the drains with pipes that are ineffective in practice, and the cost of flushing drains when using the present invention will be cut not less than 2 times. This will also allow to increase the efficiency of regulation of flushing drains drained land after a specified period of time by significantly increasing the speed of water, the slurry is carried in the header, next, in the open channel.

FIELD: land-reclamation, particularly drainage building in flooded irrigated lands.

SUBSTANCE: method involves digging out channel in a single drainage machine pass by plow-type ditcher; dumping dug out fertile ground on channel brows in banks; digging out trench by operative tool of drainage machine; laying drainage pipe and covering thereof with ground; filling channel with fertile ground. Fertile ground layer is loosened before trench digging out along drainage pipe laying axis, wherein width of loosened ground strip is not less than operative tool width. Loosened ground is laid on channel brows. Trench is dug out by chain operative tool of narrow drainage machine performing reverse rotation and extracted ground is placed between trench walls and drainage machine bunker to cover drainage pipe moved into trench by guiding means. Trench is backfilled with ground with the use of two pairs of banks, which provides successive filling trench with ground and loosened fertile ground.

EFFECT: increased efficiency due to prevention of trench wall compaction, reduced power inputs.

FIELD: hydraulic and reclamation building, particularly in permafrost zones.

SUBSTANCE: method involves creating planned embankment on territory to be developed; performing surface water drainage from embankment. Embankment slope provide water flow to water receiving means and drainage of surface water from adjoining areas. Ground water flowing from adjacent areas are drained during and/or after embankment erection and removed from embankment body. Motor roads and in-territory water draining channel systems are used as water receiving and draining means within the boundaries of territory to be developed. Water diversion ditch system is used for water removal from outside the territory to be developed. Water diversion ditch system are formed along embankment perimeter and above slopes reinforced from embankment side. Motor roads are built on embankment top, wherein motor road pavements are located beneath embankment surface. Embankment has slopes directed towards roads. Motor roads have longitudinal and transversal slopes providing surface water flow along roads to water draining channel system, which drains water into water diversion ditch system. Surface water flows into water diversion ditch system from embankment areas located at a distance from motor roads due to inclining above areas towards water diversion ditch system, which directs water to purification system or to natural temporary or permanent water channels. For ground water removal from embankment body drainage layer is placed in embankment so that drainage layer diverts accumulated water to water diversion ditch system, which is also used to remove ground water entering from areas located adjacent territory to be developed.

EFFECT: simplified structure, reduced labor inputs, provision of stable and effective protective system operation.
