Description

Embedded bulging water stopping method for pipe section joint and embedded bulging water stopping belt

Technical Field

The invention relates to a water stop, in particular to an embedding expansion pressure water stop method of a pipe section joint part and an embedding expansion pressure water stop, and belongs to the technical field of leakage prevention of underwater engineering.

Background

The rubber waterstop is arranged in a construction joint and a deformation joint when being applied to concrete cast-in-place and integrated with a concrete structure, and generates elastic deformation under various loads by utilizing the characteristics of high elasticity and compression deformation of rubber, thereby playing the roles of effectively fastening and sealing, preventing water leakage and water seepage of a building structure and damping and buffering, and being widely applied to building structures such as underground facilities, tunnel pipe galleries and the like.
