Problems solved by technology

[0009] The first object of the present invention is to solve the problem that the geomembrane is easily leaked when bolted on the steep rocky high slope and the slope with local depressions, and to provide a kind of technology that is mature, convenient for construction, and high in safety. The special slope geomembrane fixed structure of the landfill site
[0010] The second purpose of the present invention is to solve the problem that the existing geomembrane and steep rocky high slopes and slopes with local depressions do not have a good fixing method, and to provide a method that is convenient for construction, safe in operation, and mature in technology. Special slope geomembrane fixation method for landfill

Abstract

The invention discloses a landfill special slope geomembrane fixing structure and method. The structure comprises a slope, an underground water guide and draining layer, an under-membrane protecting layer and a base geomembrane, wherein the underground water guide and draining layer and the under-membrane protecting layer are laid on the slope, the base geomembrane is laid on the underground water guide and draining layer and the under-membrane protecting layer, the base geomembrane, the underground water guide and draining layer and the under-membrane protecting layer are integrated with the slope through clasp nails, the upper cover of each clasp nail is provided with a low-foaming closed-cell foam board, a double-polished-face geomembrane covers on the low-foaming closed-cell foam board, and the periphery of the double-polished-face geomembrane is welded with the base geomembrane. By the landfill special slope geomembrane fixing structure and method which is mature in technology, convenient in construction and high in safety, the problem that leakage occurs easily when bolts are used to fix the geomembrane on a steep rock slope and on a slope with partial recesses.

Description

technical field [0001] The invention relates to the technical field of environmental protection engineering, in particular to a geomembrane fixing structure for a special slope of a landfill and a fixing method thereof. Background technique [0002] Harmless landfill is currently one of the main ways to deal with domestic garbage, tailings and other solid and liquid waste that pollute the environment in the world. In order to prevent pollutants from polluting the surrounding environment, the more common method is to landfill Geomembrane is used on the bottom, side slope and top of the area to isolate pollutants from the surrounding environment. The laying and anchoring practices of geomembrane at the bottom of the reservoir, conventional slopes, and closures have been clearly defined. However, for how to fix the geomembrane to the steep rock slope and the slope with local depressions, how to fit the geomembrane to the sunken slope And other special fixing methods are not sp...
