The method of fighting fires on peatlands


(57) Abstract:

The invention relates to methods of preventing the spread of fires on peat fields lining the trench at the depth of the peat to fill her non-combustible material. The objective of the invention is a cheaper way of dealing with fires on peatlands. According to the method, the trench is filled with sphagnum moss with its subsequent hydration. Due to the high hydrophilicity sphagnum moss absorbs a lot of moisture, holding it for a long time. With the approach of the fire to the trench sphagnum moss is heated, resulting in intense evaporation. Pairs, displacing from the cavity of the trench atmospheric air, it creates an oxygen-free environment, while penetrating into the porous walls of the trench and hydrating it. Moist sphagnum moss, while in steam oxygen-free environment, not able to burn and effectively prevents the spread of fire beyond the area of localization. Significantly reduced water consumption, are excluded onward transportation of non-flammable materials, reduced labor costs.

The invention relates to methods of preventing the spread of fires on peat fields lining the trench at the depth of the peat is s trenching at the depth of the peat to fill her non-combustible material, which use mineral soil [1].

The disadvantage of this method is the high cost of development and transportation of mineral soil, because the extraction of soil requires the use of energy-intensive equipment, and delivery vehicles heavy vehicles, gain access to the fire scene to the same difficult due to the low bearing capacity of peat-boggy soils.

The closest to the technical nature of the invention is a method of fighting fires on peatlands, including trenching at the depth of the peat to fill her non-combustible material, which is used as water [2].

This method is also characterized by high costs due to the need to transport large amounts of water, because after filling of the trench it is quickly absorbed into the peat and want to maintain it level.

The objective of the invention is a cheaper way of dealing with fires on peatlands.

This technical result in the method of fighting fires on peatlands, including trenching at the depth of the peat to fill her non-combustible material, is achieved by Arami on peatlands is carried out using known hardware: the harvesting of sphagnum are a tool for removing moss cover (and.with. The USSR 1106026, class A 01 B 35/16), trenching and populate it with sphagnum moss is used in land reclamation device for drainage of soils with simultaneous filling of the cavity drains fibrous filter material.with. The USSR 1372021, CL E 02 F 5/10), hydration of sphagnum - manufactured backpack fire extinguisher-sprayer SART-M

Before working on the localization of peat fire in the hopper device for drainage of the soil are filled with sphagnum moss, and satchels fire extinguishers - water. During the movement of the device along the intended route of his working body lifts trench, in which the hopper is fed with simultaneous compaction of the peat moss. As the filling of the trench operator armed with a backpack fire extinguisher, wets laid in a trench the peat moss with water. Sphagnum moss has the ability to rapidly absorb moisture and hold it in their cells in an amount of 30-40 times its own weight. Due to the high hydrophilicity of the peat moss when wet becomes non-combustible material, the same property of sphagnum allows to reduce the consumption of water on the barrier and to minimize its losses in the form of leaks.

With the approach of the peat fire to trench the temperature of its internal the ECJ intensive evaporation. Water vapor, displacing from the trench atmospheric air, creates in its cavity anoxic environment than increase the protective properties ontakedamage barrier. In addition, couples, penetrating into the porous walls of the trench and hydrating it begins to counteract the burning before it reaches the inner wall. The final stop of the fire is provided with moist sphagnum moss, which, due to the large amount of moisture absorbed and being in a steam environment, not able to burn.

This method provides, therefore, a reliable localization of the peat fire at a relatively low cost for its implementation. Compared with the known methods is significantly reduced water consumption, are excluded long-distance transport of non-flammable materials do not require energy-intensive technical equipment for mining, loading and transportation to the place of manufacture of fire works. In the fight against peat fires sphagnum moss is not a scarce material, as found in peatlands.
