Open-pit mine slope anti-seepage drainage system

Abstract

The invention discloses an open-pit mine slope anti-seepage drainage system comprising an impermeable layer, a slope top anchoring ditch and a slope toe drainage ditch. One end of the impermeable layer is laid down the slope from the slope top anchoring ditch, and the other end of the impermeable layer extends to the slope toe drainage ditch, and is laid on the side wall and bottom of the slope toe drainage ditch completely; the impermeable layer is externally pressed and fixed by wire ropes, and the wire ropes comprise a longitudinal wire rope and a horizontal wire rope; the longitudinal wirerope is vertically connected to the horizontal wire rope, and the top end of the longitudinal wire rope is fixed in the slope top anchoring ditch; and the bottom end of the longitudinal wire rope extends to the slope toe, and the two ends of the horizontal wire rope are connected to the longitudinal wire rope separately. The anti-seepage drainage system has the advantages of the rational structure, low technical risk and high practicability, and the engineering cost can be saved; and the anti-seepage drainage system has higher promotion and application value in the slope protection engineering.

Description

technical field [0001] The invention belongs to the technical field of slope anti-seepage protection engineering, and in particular relates to a slope anti-seepage drainage system in an open-pit mine. Background technique [0002] Slope stability is greatly affected by rainfall infiltration. The reason why rainfall is an important factor leading to slope instability is mainly because rainfall infiltrates into the rock mass from the surface and further increases the pore water pressure, which is extremely unfavorable for slope stability. On the other hand, the physical and mechanical properties of the rock and soil will change after the rock mass is soaked in water, and the strength will decrease, that is, the phenomenon of hydration will occur, which will lead to the easy instability of the rock and soil mass. [0003] There has always been such a problem in the anti-seepage engineering of high slopes in open-pit mines. The method of concrete shotcrete is used for protection...

AI Technical Summary

Problems solved by technology

As the weathering degree of the slope surface deepens, the weathering speed will further accelerate. As far as the slope rock mass is concerned, if the slope is not properly protected, the surface of the rock mass will be weathered and peeled off, and the weathering will continue to deepen, affecting the stability of the slope.

At present, for the protection of slopes, some engineering fabrics are used to lay the whole line from top to bottom. Rolling stones and crushed stones on the slope are easy to tear the film, and there are large differences in length and width of the slopes, making it difficult to lay the whole line. Large, not easy to clean, and later maintenance is also troublesome
