Embodiment Construction

[0019] Such as figure 1 , figure 2 As shown, the mudstone slope surface of the waste dump is a strongly weathered mudstone layer 11 , and below the strengthened mudstone layer is a slightly weathered mudstone layer 12 . There are upper and lower two platforms 7 on the side slope, between the two platforms is a mudstone side slope 10 that has been cleared of vegetation and trimmed, and the upper side slope of the upper platform is an uncleaned hillside 10'. On the mudstone slope 10 that has removed vegetation and repaired, be covered with the thick thin layer polyethylene film 2 (purchase commercially available polyethylene film product) of 0.5-0.75mm that has added carbon black, described polyethylene film is made of many Strip-shaped polyethylene films are welded, each polyethylene film is arranged longitudinally, and the upper end of each polyethylene film 2 is anchored in the anchoring groove 8 at the lower edge of the upper platform. A plurality of soil nails 3 are long...

Abstract

The invention provides a weathering preventing and reinforcing method and a weathering preventing and reinforcing structure of a mudstone side slope of a waste residue storage yard. The method comprises the following steps of: after vegetation of the mudstone side slope (10) of the waste residue storage yard is cleared and the mudstone side slope is trimmed, covering thin polyethylene films (2) added with carbon black to prevent rainwater from intruding and isolate sunlight, wherein a plurality of polyethylene films are of banners and paved from top to bottom, and the adjacent polyethylene films are welded together; fixing the polyethylene films on the slope at welded seams (4) by using soil nails (3), and laying shims (5) between the soil nails and the polyethylene films; and hermetically covering impermeable films (6) at the combined positions of the soil nails and the polyethylene films. In the method, the problems of geological disasters such as sequential landslip and the like caused by mudstone weathering are solved by combining the weathering preventing measure of covering the thin polyethylene films on the surface of the mudstone side slope and the anti-slip measure of reinforcing the mudstone by using the soil nails.

Description

technical field [0001] The invention relates to a construction project of an industrial waste residue or tailings slag landfill (storage yard), in particular to a method and a structure for preventing and reinforcing mudstone slopes of the waste residue storage yard. Background technique [0002] Mudstone is widely distributed in Southwest my country. Mudstone is easy to weather and hydrate. The strength of the weathered mudstone is significantly reduced, and geological disasters such as collapses and shallow landslides are prone to occur. In the construction of large and medium-sized industrial waste slag or tailings slag landfills (storage yards) with film-laying and anti-seepage, it is usually necessary to clear the vegetation and level the slope of the entire storage area first, and then pile up from bottom to top. The anti-seepage membrane shall be laid on the rise of the waste slag surface in the field. However, it generally takes several years for the waste to fill...
