Impervious structure in position where pipe penetrates through impervious film and impervious method

Abstract

The invention discloses an impervious structure in the position where a pipe penetrates through an impervious film and an impervious method. The impervious structure comprises the impervious film, thepipeline, a flange clamp, a V-shaped tensioning impervious sleeve and a pipe barrel sleeve assembly. A pipeline through hole is formed in the impervious film. The pipeline penetrates through the pipeline through hole. An outer ring of the flange clamp is connected to the portion, corresponding to the pipeline through hole, of the impervious film in a sealing and clamping mode. An inner ring of the flange clamp is connected to the large head end of the V-shaped tensioning impervious sleeve in a sealing and clamping mode. The small head end of the V-shaped tensioning impervious sleeve is connected to the pipe barrel sleeve assembly in a sealing and clamping mode. The pipe barrel sleeve assembly is connected to the portion, corresponding to the pipeline through hole, of the pipeline in a sealing and sleeving mode. Through the pipe barrel sleeve assembly, sealing connection between the V-shaped tensioning impervious sleeve and the pipeline can be achieved conveniently and fast, by arranging an upper pipe barrel joint, a lower pipe sleeve joint and a sealing ring on the pipe barrel sleeve assembly, the upper pipe barrel joint and the lower pipe sleeve joint can be movably mounted in amatched mode, and the sealing ring of a wedged-shaped structure can be used for guaranteeing that the position between the pipe barrel sleeve assembly and the pipeline is in a sealing state in real time.

Description

technical field [0001] The invention relates to the technical field of anti-seepage membrane laying, in particular to an anti-seepage structure and an anti-seepage method where a pipe passes through the anti-seepage membrane. Background technique [0002] HDPE geomembrane, the full name of high-density polyethylene geomembrane is a waterproof barrier material produced from polyethylene resin, with a density of 0.94g / m or more. Because of its excellent resistance to environmental stress cracking, low temperature resistance, aging resistance, corrosion resistance, large operating temperature range (-60°C-+60°C) and long service life (50 years), it is widely used Anti-seepage projects in domestic waste landfills, hazardous waste landfills, sewage treatment plants, artificial lakes, reservoir canals, tailings treatment, petrochemical and other industries. The PE pipe has the characteristics of wear resistance, acid resistance, corrosion resistance, high temperature resistance, ...
