Sealing connection structure of HDPE (high-density polyethylene) film flexible vertical diaphragm wall

A sealing connection structure of an HDPE film flexible vertical diaphragm wall comprises an outer layer connecting sleeve and an inner layer connecting lock, and the outer layer connecting sleeve comprises an outer layer sleeve, an outer layer welding wing plate and a seam sealing plate; and the inner-layer connecting lock comprises an inner-layer perforated pipe and an inner-layer welding wing plate. The outer-layer connecting sleeve and the inner-layer connecting lock are combined through a sleeve lock structure, the inner-layer connecting lock is placed in the outer-layer connecting sleeve, and the outer-layer welding wing plate and the inner-layer welding wing plate are respectively welded with an HDPE (high-density polyethylene) film to form a flexible vertical diaphragm wall extending towards two sides. According to the sealing connection structure of the HDPE film flexible vertical anti-seepage wall, through the technical scheme, the connection integrity between HDPE films can be improved, the anti-se
