1. The scope of the invention.

The invention relates to an outdoor mountain development for reclamation of dumps.

2. Analogs of the invention.

After searching and analysis available to the author of the literary sources close to the invention, analogs was not found.

3. Disclosure of the invention.

The invention consists in forming on the inside of the blade (under the blade means all heaped ridge formed after full testing career) two or more water-resistant lenses with exit to the surface. Between the waterproof lens is formed of water-permeable lens, also with exit to the surface. After the formation of the blade permeable lens in a variety of ways saturate with water.

The implementation of the invention is

1. No need to carry out reclamation of the formed blade, as the blade is full narodnokhozyaistvennyi object - functioning hydraulic structure.

2. After filling permeable lenses water, it forms the blade, which is an artesian reservoir. Then you can pass the artesian well and receive the accumulated water for various purposes. Water in the waste can be periodically replenished.

4. A brief description of the drawings.

Drawing characterizes jus the th idea of the invention.

5. The implementation of the invention.

1. First we need to calculate the maximum power waterproof lenses.

2. Next, you need to calculate the wattage on each otsypannoy the section.

3. For necessary artesian water pressure and other factors need to choose the thickness of permeable lenses and to calculate the change in each otsypannoy the section.

4. Each section in accordance with the calculated parameters occiput impermeable and permeable layers of rock.

5. The surface of the blade is closed waterproof layer completely, leaving two outputs permeable lenses on the surface, or does not close, then the surface water will accumulate on the upper surface of the lens, forming a pressure-free reservoir.

6. After full testing career dump-reservoir is formed. Further in any way to the dump (via outputs permeable lenses on the surface) water is pumped up to complete filling of the reservoir.

7. Dump the water reservoir is a complete narodnokhozyaistvennyi object - hydraulic structure. After its formation, he commissioned. Then you can pass artesian wells and springs and to consume the accumulated water. In addition, the water in the waste can be periodically replenished.

Increase videoporn the x and mechanical properties of rocks.

During disassembly of the face waterproof breed will not remain monolithic, as you need them loosening explosion, and then the excavator bucket. Loosened the confining beds have a large amount of pore space and confining beds are not, therefore, need to restore their water-resistant properties. We can distinguish the following methods of increasing resistance and strength properties of rock:

1. Technological method.

1.1. The dumping of rocks from a great height - the maximum height of unloading excavator.

1.2. The pressure on the breed weighing mining equipment (excavation excavator impermeable layer).

2. Technical method.

2.1. Encapsulating breed in technical devices (metal, wood, concrete, cement, brick, canvas).

3. Injection method.

3.1. Introduction in the pores and cavities of rocks cementing materials (concrete, cement, bitumen, liquid glass, synthetic resin, clay).

4. Cryogenic method.

4.1. Cooling of the rocks.

4.2. Freezing of water in the rock.

The method of forming the blade in the form of artesian reservoir, comprising filling the inside of the blade first layer of impermeable rocks, then a layer of permeable rock, and on top of this layer of another waterproof layer, forming these layers in the form of lenses, with exits to the surface, through which the permeable layer pump in the remote control.

SUBSTANCE: invention relates to the field of hydrotechnical and land reclamation construction and is intended to provide for stability of soils in general planning embankments of developed lands. Method includes development of general planning embankment on site of developed territory and performance of protective measures in two stage, the first of which - in initial period of construction to provide for embankment fitness for performance of construction works in normal mode, and the second one - in final period of construction to provide for stability of embankment soils in process of its whole service life. At the first stage embankment is filled in several stages. At the first stage pioneer bed of embankment is formed, which is filled in layers in winter period of time during the first year of construction onto surface of formed layer of seasonal frost penetration cleaned from snow by layers having thickness that provides for the possibility of their additional compaction. If general planning embankment is erected from water-saturated soils, filling of embankment on the site of developed territory is carried out in separate sections of rectangular shape in plan. Separate sections of embankment are erected without their mutual merging, thus creating channels between separate sections of embankment for waters drain in warm period of the year. Neighbouring separate sections of embankment are joined by embankment passages arranged across mentioned channels to provide for free change-over of construction equipment from one section of embankment to another one. Culverts are arranged in embankment passages. At the second stage - in subsequent summer period of time in the second year of construction, after pioneer bed of embankment has melted down to the depth that equals 70-80% of its thickness, its additional compaction is started, besides additional compaction of embankment pioneer bed is completed to the moment of melting for the whole thickness and prior to beginning of melting in soils of natural origin that are arranged under pioneer bed. Another layer of embankment, second in height, is filled with layer compaction and filling of channels for water drain. Thickness of embankment layer second in height is arranged as not exceeding difference between value of rated depth of filled soils melting in this climatic region and value of thickness of embankment pioneer bed. If value of overall height of general planning embankment exceeds value of rated depth of seasonal melting for filling soils used for its erection, at another stage - another bed of embankment, next in height, with thickness of not more than rated depth of melting for filling soils is filled in winter period of time onto surface of embankment, preceding in height, cleaned from snow, after its complete frost penetration. Filled bed of embankment is also additionally compacted in summer period of time after its melting to the depth equal to 70-80% of its thickness. Further subsequent stages are repeated until general planning embankment is not brought till design height. At the second stage for protection of general planning embankment for the whole of its service life against water saturation with thawed and rain waters, and also with waters that arrive from adjacent territory, at the last stages of general planning embankment filling, measures are taken for organisation of long-term water-removal system and anti-filtration devices.
