Description

Improved water-swelling rubber water stop

Technical Field

The utility model relates to a sealing rod, specific water-swelling rubber waterstop that says so is used for follow-on.

Background

The water stop is arranged in the deformation joint and the construction joint in the process of pouring the concrete for tunnel construction, and the water stop and the concrete structure form a whole foundation engineering to form a complete waterproof layer. Because the rubber has the characteristics of high elasticity and compression deformability, the construction joint and the deformation joint can realize elastic deformation under various loads, thereby playing the role of effective firm sealing.

The currently used water stop belts are generally common rubber water stop belts, steel-edged rubber water stop belts and the like. In practical engineering application, the waterstop is easy to have the following problems that the adhesion force of concrete and rubber is poor, the rubber is a soft elastic body, the concrete is not easy to be tamped when being poured, so that the problem of surrounding leakage is caused under the condition of high water head pressure, the waterstop is easy to loosen, fall off and even be pulled out due to the large elasticity and poor rigidity of a rubber waterstop stem of the waterstop when a concrete joint is expanded, pulled off and twisted and is subjected to large deformation, and the service life of a product is seriously influenced due to the fact that a steel edge waterstop is corroded due to the surrounding leakage when the steel edge waterstop is subjected to the surrounding leakage.
