Description

Technical Field

Background

The rubber waterstop is mainly used for foundation engineering which is arranged in a construction joint and a deformation joint and integrated with a concrete structure when concrete is cast in place, such as underground facilities, tunnel culverts, water delivery aqueducts, retaining dams, liquid storage structures and the like. The construction joint and the deformation joint are the weakest links of a concrete structure, so the positions of the construction joint and the deformation joint are the main positions for generating water leakage in civil engineering; in actual engineering, most construction joints and deformation joints have leakage phenomena. In order to prevent the building from being damaged due to the penetration of water to certain parts of the building, rubber water stops are usually arranged at construction joints and deformation joints.

The expansion and contraction rate of the rubber water stop is smaller than the deformation of the construction joint and the deformation joint due to overlarge settlement difference and local inclination, so that the rubber water stop is torn to cause leakage. On the other hand, due to the characteristics of concrete, uneven settlement is generated when the concrete is solidified, and the rubber water stop at the construction joint and the deformation joint is broken to cause leakage to a certain extent.
