Embodiment 1

[0029] Such as figure 1As shown, the present invention is an anti-seepage structure where a pipe penetrates the anti-seepage membrane, including an anti-seepage membrane 1, a pipe 2, a flange clamp 3, a V-shaped tension anti-seepage sleeve 4 and a tube sleeve assembly 5, and the anti-seepage membrane It is an anti-seepage material made of PE film as the base material and composited with geotextiles. Its anti-seepage performance mainly depends on the PE film. The PE film used in the Oriental anti-seepage film mainly includes polyvinyl chloride, polyethylene, and EVA (ethylene / vinyl acetate copolymer). They are a kind of polymer chemical flexible material with a small specific gravity, strong extensibility, and adaptability to deformation. High, corrosion resistance, low temperature resistance, good frost resistance. The main mechanism is to block the leakage channel of the earth dam by the impermeability of the plastic film, and to withstand the water pressure and adapt to the...

Embodiment 2

[0039] Such as figure 1 As shown, a kind of anti-seepage method at the place where the pipe penetrates the anti-seepage membrane of the present invention is characterized in that it comprises the steps:

[0040] A pipeline through hole is opened on the anti-seepage membrane 1, the pipeline 2 is pierced in the pipeline through hole, and the outer ring of the flange clamp 3 is tightly clamped and connected to the anti-seepage membrane 1 corresponding to the pipeline through hole. The inner ring of the flange clamp 3 is sealed and clamped to the large end of the V-shaped tensioned anti-seepage sleeve 4, and the small end of the V-shaped tensioned anti-seepage sleeve 4 is sealed and clamped to connect to the tube sleeve assembly 4. The pipe sleeve assembly 4 is tightly sleeved and connected to the pipe 2 corresponding to the pipe through hole.

[0041] The pipe sleeve assembly 5 includes an upper pipe joint 10, a lower pipe joint 11 and a sealing ring 12, and the upper pipe joint...

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, ...
