Landslide construction

 

The invention relates to the construction, in particular for the strengthening of landslide-prone slopes, and can be used in the development of unstable areas of the built-up territory, composed of gravel and clay soils. Landslide structure includes a series of bored piles, combined grillage and placed across the landslide slope, and drainage system from porous concrete and leaving the channel. What's new is that in the series of piles made through one combined - in the lower part of the heavy concrete and the top of the porous, and have a frame made of non-corroding cast reinforcement, outer and middle row of piles made entirely of heavy concrete, landslide structure has an additional discharging channels made in the form of inclined drain in drilled wells, the beginning of which is installed at the end of the upper part of the composite piles. The technical result of the invention is to increase the effectiveness of landslide protection works by intercepting the jet of groundwater flow and reduce earthworks. 1 Il.

The invention relates to the construction, in particular for the strengthening of landslide-prone slopes, and lineStyle soils.

Known retaining structures including bored piles and uniting them gratings (Braslavsky C. D. Landslide designs on the roads. - M.: Transport, 1985, Fig.5.2, 5.4, S. 162, 163, 180).

The disadvantage of these constructions is that for dewatering, which, picking up moisture, may prodavlivaetsya between the piles, it is necessary to lay the drainage system of devices for collecting and removing groundwater. This horizontal, vertical and combined drainages, including horizontal well drainage. The lack of the latter in a jet movement of groundwater is low efficiency, because they can not intercept groundwater flow.

Closest to the claimed invention, the essential features and achieved technical result is a landslide structure, including a series of bored piles, combined grillage placed across the landslide slope, and drainage system from porous concrete and discharging channel (see EN 2122072 C1, E 02 D 31/08, 29/02, 20.11.1998).

The disadvantage of this landslide structures is limited use of the tongue dive in which the soils, vkluchaetsia improving the efficiency of stabilization of landslide slopes due to interception inkjet groundwater flow and reduce earthworks.

The problem is solved due to the fact that the landslide construction including a series of bored piles, combined grillage placed across the landslide slope, and drainage system from porous concrete and leaving the channel, according to the invention, in a row of piles made through one combined - in the lower part of the heavy concrete and the top of the porous, and have a frame made of non-corroding cast reinforcement, outer and middle row of piles made entirely of heavy concrete, protivoopolznevye construction has the additional discharging channels made in the form of inclined drain in drilled wells, the beginning of which is installed at the end of the upper part of the composite piles.

The technical result of the invention is to increase the effectiveness of landslide protection works by intercepting the jet of groundwater flow and reduce earthworks.

The essence of the invention illustrated by the drawing, which shows a landslide structure.

Landslide structure consists of a series of bored piles, placed across the landslide array. For pile drilling of wells 1, they are reinforcing cages 2. Extreme and among non-corroding cast valve 4 and the upper part made of porous concrete 5. The number of piles combined grillage 6. Sbrasyvatsya channels 7 made in the form of inclined drain in drilled wells, the beginning of which is located at the end of the upper part of the composite piles.

Landslide structure erected as follows.

Previously, the calculation is determined by the location of the landslide protection works. For a number of piles drilling of wells 1 and set them in reinforcing cages 2. Fill the outer and middle wells, and the lower part (below the surface displacement of the landslide) staging piles of heavy concrete 3. Set in well combined piles frames made of non-corroding cast valves 4 and fill these wells porous concrete 5, combine all bored pile grillage 6, and further discharging channels 7 are in the form of inclined drain in drilled wells, the beginning of which is installed at the end of the upper part of the composite piles.
