Composite geo-membrane sealing joint and manufacturing method thereof

Abstract

The invention discloses a composite geo-membrane sealing joint and a manufacturing method thereof which are used for carrying out sealing connection between seams of composite geo-membranes while the composite geo-membranes are vertically paved underwater and are capable of enabling the composite geo-membrane sealing joint to be sealed and reliable and the structure strength of the composite geo-membrane sealing joint to be larger than the tension strength of the composite geo-membranes, and belongs to the field of foundation seepage-proofing engineering. The composite geo-membrane sealing joint adopts a connecting mode of sleeving inner sectional materials and outer sectional materials, the inner sectional materials and the outer sectional materials are respectively connected with the composite geo-membranes, and welding and adhesive connecting are carried out on the ground. According to the composite geo-membrane sealing joint and the manufacturing method, disclosed by the invention, solidifying materials can be poured into the inner sectional materials and an annular gap between two pipes after the inner sectional materials and the outer sectional materials are sleeved underwater, the sealing of the inner sectional materials and the outer sectional materials can be realized, and the sealing connection between the composite geo-membranes can be finally achieved. Due to the composite geo-membrane sealing joint disclosed by the invention, the situation of vertically paving the composite geo-membranes underwater becomes possible.

Description

technical field [0001] The invention discloses a composite geomembrane sealing joint, in particular discloses a sealing connection joint used for vertically laying composite geomembrane joints underwater and a manufacturing method thereof, and belongs to the field of foundation anti-seepage engineering. Background technique [0002] At present, vertical plastic laying is a widely used anti-seepage technology, which has the advantages of low cost and good anti-seepage effect. The principle is to lay the plastic film vertically after mechanical slotting, the plastic film is pre-rolled on a shaft, put it vertically into the bottom of the groove, roll the reel forward to spread the plastic film, and the connection between the films is 2~3m The way. The existing vertical plastic laying has the following obvious disadvantages: [0003] (1) The plastic film has no protective layer, and it is easily scratched by sharp objects when laying, which reduces the anti-seepage performance...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the technical problems existing in the prior art, the present invention discloses a composite geomembrane sealing joint and a manufacturing method thereof. The composite geomembrane sealing joint of the present invention solves the sealing problem between underwater composite geomembrane joints, and enables The feasibility of vertically laying composite geomembrane under water is greatly improved, which solves the shortcomings that only unprotected plastic film can be used for vertical laying and the joint method is unreliable.
