Problems solved by technology

[0007] The above-mentioned reinforcement methods have a better reinforcement effect when reinforcing slopes, but for large-area landslide slopes, they still rely on anchor cables and steel beams for reinforcement, which makes construction difficult, heavy workload, and high cost

Abstract

The invention provides a method for enhancing the stability of a landslide slope of an abandoned mine. The method includes the following steps that S10, basic data are acquired; S20, drainage holes are constructed; S30, reinforcing units are constructed, and each reinforcing unit comprises a pre-stressed anchor cable, a wall-attached tray and multiple anchor rods; S40, connecting beams are constructed, and a branch support plate of one reinforcing unit is connected with a branch support plate of another adjacent reinforcing unit through the corresponding connecting beam. According to the method for enhancing the stability of the landslide slope, the stable stratum and the unstable stratum are connected through the pre-stressed anchor cables, so that the unstable stratum can be effectivelyprevented from side-slipping; the pre-stressed anchor cables and the anchor rods are connected into a whole through the wall-attached trays, so that a complete stressed body is formed in the slope protection zone, the slope protection area can be increased, and the support stability can be improved; and when the unstable stratum has the downwards slipping tendency, the anchor rods, the pre-stressed anchor cables and the wall-attached trays can be stressed simultaneously, and the threat caused by strain can be weakened.

Description

technical field [0001] The invention relates to the technical field of slope treatment of abandoned mines, in particular to a method for enhancing the stability of landslide-type slopes of abandoned mines. Background technique [0002] Mine provides rich mineral resources for industrial production. During the mining process, it will cause great damage to the natural mountain and surrounding vegetation, and at the same time form unstable albino slopes. On the one hand, these slopes have geological disasters such as collapses and landslides. On the other hand, it is easy to cause serious water and soil erosion. After the mine is abandoned, due to lack of management, geological disasters often occur. [0003] At present, the treatment method for abandoned mines is to first evaluate the stability of the mine slope, and then carry out reinforcement, greening or direct greening according to the stability of the slope. [0004] For landslide slopes, reinforcement is first required...
