Embodiment 1

[0034] An embodiment of the present invention provides a method for repairing anti-seepage and weathered bedrock at the bottom of a waste residue or tailings stockyard, comprising the following steps:

[0035] S1 cleaning the surface of the bedrock layer (1) by means of negative pressure suction to expose the bedrock layer 1;

[0036] S2 Adding polymer glue to the crack 2 of the bedrock layer 1, the polymer glue is a colloid formed by reusing slag, which has the advantage of environmental protection;

[0037] S3 Constructing an anti-seepage layer 3 on the surface of the bedrock layer 1 to prevent the infiltration of polluted liquid. By adding the polymer glue in the cracks 2 of the bedrock layer 1, the bearing strength of the bedrock layer 1 can be effectively increased to ensure construction safety. Moreover, the anti-seepage layer 3 on the surface of the above-mentioned polymer glue and the bedrock layer 1 can effectively prevent industrial waste, process waste liquid, chem...

Abstract

The invention discloses a method for repairing anti-seepage weathering bedrock at the bottom of a waste slag or tailings storage yard. The method comprises the following steps that S1, the surface of a bedrock layer is cleaned to expose the bedrock layer; S2, filler is added to cracks of the bedrock layer; and S3, an anti-seepage layer is constructed on the surface of the bedrock layer to prevent infiltration of polluted liquid. The cracks of the bedrock layer are filled with the filler, the problem of insufficient strength in the prior art due to the existence of a large number of cracks in the bedrock can be effectively solved, and the problem of serious environmental pollution caused by the infiltration of industrial waste liquid, chemical products, slag and the like into the bedrock layer is solved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a restoration method for anti-seepage and weathered bedrock at the bottom of a waste residue or tailings stockyard. Background technique [0002] On the bedrock, it is common to see the peeling phenomenon of layers roughly parallel to the surface, which is called exfoliation. The reason for spalling on the surface of bedrock is related to the unloading of bedrock in addition to the reason of temperature difference and weathering. The rocks that were originally buried deep underground were subject to greater confining pressure. When the overlying rock blocks are eroded away, the reduction of the upper pressure causes the bedrock to expand upwards, resulting in fracture surfaces roughly parallel to the exposed surface of the bedrock and some cracks near the vertical surface. This spallation, combined with other weathering, can create stripped mounds protruding from...
