Abstract

The invention provides an underground polyethylene geomembrane connector and a construction method thereof. The underground polyethylene geomembrane connector comprises a connector body. Grouting grooves are formed in the two sides of the connector body correspondingly. A fixing connecting part is arranged in each grouting groove, wherein the grouting groove and the fixing connecting part extend to the middle portion of the connector body from the side end of the connector body. The two side ends of the connector body are provided with openings leading to the grouting grooves, and accordinglyan impermeable membrane or a permeable membrane stretches into the openings. The fixing connecting parts fix the impermeable membrane or the permeable membrane in a winding manner, a water encountering expansion body is arranged between the inner wall of each grouting groove and the corresponding fixing connecting part, and the impermeable membrane or the permeable membrane is jacked through the water encountering expansion bodies. The underground polyethylene geomembrane connector and the construction method thereof solve the problem about how to apply a polyethylene geomembrane to underground anti-seepage treatment construction, the construction quality and efficiency are further improved, and pollution possibly caused by construction is reduced.

Description

technical field [0001] The invention belongs to the technical field of underground anti-leakage of buildings, and relates to an underground polyethylene geomembrane joint and a construction method thereof. Background technique [0002] Underground anti-seepage treatment is mainly used to cut off the connection of groundwater. The main method is to seal the groundwater pollution source in one area, thereby preventing the pollution source from spreading, and avoiding continuing to pollute the clean groundwater. [0003] At present, in the construction of the underground diaphragm wall, the construction method of concrete pouring anti-seepage wall is widely used in the existing ones. However, this approach will cause cracks during long-term use on the one hand, and its reliability is poor; on the other hand, it will also cause secondary pollution, which is not conducive to environmental protection. Contents of the invention [0004] One of the purposes of the present inventi...
