The invention relates to engineering preparation of territories, engineering protection of territories of capital construction projects of all sectors of the economy and the preservation of basic quality of life factors in the environment, primarily soil, groundwater and open water.

Technical solutions of the present invention is directed to regulation:

- groundwater level;

- salinity drainage water;

- desalinization drained soil mass;

- the quality of soil, groundwater and surface water in case of emergency spills of pollutants on the local area of the earth;

- collection, storage, dilution of the effluent in the soil solid Foundation of design, not isolated from the natural environment existing and rekultiviruemye landfills of municipal solid waste (MSW),

- recirculation of leachate into the environment solid waste to create favorable conditions for their biological and chemical processes

FIELD: agriculture, in particular, desalinization of saline soil of agricultural lands.

SUBSTANCE: method involves cutting slits on plot to be desalinized; feeding rinse water onto strips between slits; removing salt from slit surfaces and spilling soil therein, with slits being cut to depth exceeding depth of season soil wetting with precipitation; providing cavities on strips between slits; closing cavities with shields of hydrophobic water-impermeable material, said shields being equipped with perforations extending along their central axes and float members; fastening shield edges in upper part of slits; providing soil desalinization facilitated by precipitation. Upon precipitation, rain water flows over walls of cavities to infiltrate through perforations and fill cavities bottom part, with the result that salt is washed into depth of soil to be desalinized. Moisture will be preferably moved by capillary force and due to evaporation of moisture from slit wall surfaces toward slit walls, accompanied by accumulation thereon of salts. Washing process may be accomplished during one or several seasons depending upon precipitation intensity and salt concentration. After completing of desalinization processes, shields are removed, salts are buried by spilling soil into slits, and soil on desalinized plot is mellowed to depth of season soil wetting. Burying of salts at the level below depth of season soil wetting and destruction of capillaries by deep mellowing of desalinized soil layer protect it from secondary salinization.

EFFECT: increased fertility of agricultural areas on unirrigated agricultural lands in the absence of potable water sources without the necessity of constructing expensive water feeding systems.

The invention relates to mining and can be used to increase the stability of the dams, including existing and reconstructed tailings storage areas with permafrost soils (VG)

FIELD: water protection.

SUBSTANCE: invention relates to the area of environmental protection, and namely to the protection of open water bodies. The method comprises arrangement of drainage elements of open and closed types, arrangement of a reservoir for waste water collection and drainage of contaminated water. Additionally the planning of the layout of the area surface of stored solid waste is performed through technical means to ensure a gradual increase in the slope of its surface from the top of the area of waste to the bottom towards the water edge of the water body on the one side and from the top to its bottom in the opposite direction on the other side of the water body. Drainage elements of open type are arranged in the form of internal and external rallying ditches and an outlet ditch. The internal rallying ditch is placed along the bottom of the area of waste both on the side of the water body and on the site that is opposite to it. The exterior rallying ditch is placed only along the base of the area of waste which is furthest to the water body behind the rallying ditch. The outlet ditch is placed from the exterior rallying ditch to the water edge of the water body. Reservoirs for collection of contaminated water in the form of individual open tanks are placed outside the exterior rallying ditch along the base of the area of waste which is remote from the water body. Drainage elements of closed type are placed as closed rallying tanks as well as connecting pipes and drainage rallying pipes under the area of assorted waste. And the connecting pipes connect internal rallying ditch with the closed rallying tanks and the drainage prefabricated pipes connect them with the tanks for collection of contaminated water. The area of waste is covered with two layers of thin material: first, the lower one - the drainage material, and the second, the upper one - waterproof material. For the upper, waterproof material rolled material of width b is used. Coverage is carried out on the lower layer of drainage material by unrolling the rolls in strips from the external rallying ditch along the slope of the area of waste towards the top of the area of waste and further to the water edge of the water body. Laying of the strips of the upper waterproof material is carried out in the following sequence: the first, third, second, fifth, fourth, seventh, sixth, ninth, eighth, etc. Distances between the odd stripes stand out to be (0.7-0.8) to provide the strap of the adjacent stripes (odd and even) to each other by the width (0.15-0.10)5. After laying two layers of material they are perpetuated to the area of waste by means of pins which are arranged along the set stripes of material on caps. The lower edge of the drainage material around its perimeter is placed in the internal rallying ditch. The lower edge of the waterproof material is placed from the side of the area of waste which is remote from the water body - in the exterior rallying ditch, and from the side of the base of the area of waste adjacent to the water body - on the ground and into the water body. Pollution agents are prevented from getting into the water body.

FIELD: agriculture.

SUBSTANCE: method includes soil drying by a closed header with rarefied parallel drains and a double-slope profile of soil surface between them. The profile of soil surface is developed by means of multiple ploughing into a plow ridge by inclosures with width equal to the distance between drains, and with formation of split furrows placed in the same vertical plane with drains. In process of ploughing a double-slope profile is also given with an inclination of less than 0.01 of the horizontal surface of the low-water-permeable subsurface horizon - a ploughing foot of subsurface. The double-slope profile of the subsurface horizon is developed by tilling soil of the subsurface horizon with increased thickness of the tilled later from the plow ridge to a split furrow and subsequent ploughing to the tilled topsoil. Previously prior to tilling, two increasing doses of lime, phosphorite flour, organic and mineral fertilisers are added from the plow ridge to the split furrow, which are assigned with account of growing thickness of tilled and ploughed topsoil of the subsurface horizon.

EFFECT: such technology will make it possible to speed up drainage of surface waters and gravitation of upgrade water from topsoil, to level fertility of topsoil between drains, to develop a thick fertile topsoil and to increase capacity of crops grown on drained heavy low-water-permeable soils.
