The invention relates to the field of construction and mining and can be used when securing ledges quarry, construction of roads, tunnels, exposed to groundwater.

Known way to prevent landslides, consisting in the interception of groundwater by means of drainage excavation perpendicular to the direction of flow flowing from aquifers water and connected with drilled from the surface vertical wells, which is the end-to-end filters, crossing all aquifers, and drilled from the excavation itself dewatering wells (see EN 2244063).

The disadvantage of this method is that this method is not applicable in quarries, working on roads, tunnels and so forth, with the small size of landslides.

There is a method of dehydration of the landslide body single end-to-end filter, namely, that with the foot of a cliff or slope, or slope, or slope are drilling horizontally-inclined borehole with a diameter of 1.8 m and with the rise of i=0,005-0,007 into the ledge or slope, or slope, or slope beyond the landslide body, from the surface of the ledge or slope or slope or slope are drilling a vertical well to pairing with a horizontally-inclined well bore at a single skvoz the nd filter diameter from 200 to 500 mm, the pair arranged in the camera connection to a vertical borehole from the surface down a single end-to-end filter, made in the form of a pipe with perforated sections of holes and filter elements made at the level of pairing with each aquifer, and the intersection with aquifers sprinkle fine material, such as gravel, crushed stone, polymer beads, with horizontally-inclined well laid pipe, in which the camera connection connect with the pipe lowered in a vertical well, the connection pipes set adjustable valve with a common water meter, and after each filter element install water meters.

The disadvantage of this method is that this method does not provide a complete abstraction of surface and groundwater.

The task of the invention is to ensure the reliability of preventing the formation of landslides due to the complete drainage of surface water and groundwater from the landslide body.

The problem is solved in that in the method of dehydration of the landslide body, which consists in the fact that they are carrying out engineering-geological and hydrogeological investigations to determine the presence of landslide bodies, then hold the dowsing survey, the results of which is determined by the earth's waterways and find out their characteristics to determine the number and location of end-to-end filters, then, on the surface of the ledge or slope, or slope, or slope outside the landslide body are collector for collecting surface water and shallow part of the watercourse, then the foot of a cliff or slope, or slope, or slope are drainage development in depth of the shelf, or slope, or slope, or slope beyond the landslide body, from the surface of the ledge or slope, or slope, or slope are drilling vertical wells to pair with drain output under end-to-end filters, mate equip cameras connection in vertical wells from the surface down through the filters, made in the form of tubes with perforated sections of holes and filter elements made at the level of pairing with underground watercourses and drains and drain production are bias i=0.005 in the direction of flow for gravity flow of intercepted water. While the bottom and the walls of the collector are made of gabion structures.

The invention is illustrated by drawings, where Fig.1 shows a vertical longitudinal section of the components of strata of rocks and underground watercourses with header and through the filter; Fig.2 is a plan of the network of drainage systems; Fig.3 is a vertical cross-section area of interception of surface and groundwater (a - a section I-I, b - section II-II - section III-III).

The method of obtw the survival of the landslide body 1 is carried out as follows: conduct geotechnical and hydrogeological studies using network Supervisory hydrogeological wells 2 to determine whether the landslide tel 1, then hold the dowsing survey, the results of which determine subterranean stream (3 deep and shallow 4) and investigate their characteristics (depth, direction of water flow rate (l/s), the number of underground watercourses, PCs, their sgruppirovannoe) to determine the number and location of end-to-end filter 5, and then, on the surface of the ledge or slope, or a slope, or a slope of 6 outside of the landslide body 1 are manifold 7 for collecting surface water and part of the shallow watercourses 4, then the foot of the scarp, or cliff or slope, or slope 6 are drainage production 8 in the depth of the shelf, or slope, or a slope, or a slope of 6 outside of the landslide body 1, with the surface of the ledge or slope, or slope, or slope 6 are drilling vertical wells to pair with drain output 8 under through the filters 5, the pair are arranging a camera connection 9, in a vertical borehole from the surface down through the filters 5, made in the form of tubes with perforated sections of holes and filter elements made at the level of pairing with underground streams 3 and 4, moreover, the collector 7 and the drain 8 production are bias i=0.005 in the direction of flow for gravity flow of intercepted water in the drainage ditch 10 to reset the intercepted water in the river, lake, nisi is at or chute 11. While the bottom and the walls of the collector 8 is made of gabion structures 12. Moreover, end-to-end filters are drilling on a group of underground watercourses, so that their depression funnel 13 overlaps the adjacent 5-6 m to intercept water from underground streams 3 and 4 (see Fig.2).

Thus, surface water and groundwater are caught in the area of the depression cone 13 through filter 5 and the collector 7 to collect surface water through drainage ditch 10 is discharged by gravity into the river, lake, marsh or chute 11, not bringing the ravages of the earth's surface and all existing structures, i.e., eliminated the formation of landslides.

If the bottom surface of the water course mainly contains sludges, sapropels, peated soils or peats, then the FCM is oriented to the bottom surface with its any side. The flexible concrete mat comprises concrete blocks, connected to each other row by row and in rows with at least one connection element.
