Novel water interception system for subway tunnel deformation joint

Abstract

The invention discloses a novel water interception system for a subway tunnel deformation joint, and belongs to the technical field of deformation joint water interception devices. According to the technical scheme, the novel water interception system is characterized by comprising a deformation joint liner plate and a water receiving box, the deformation joint liner plate is located in a deformation joint, an isolating membrane is arranged at the bottom of the deformation joint liner plate, and sealant is smeared at the bottom of the isolating membrane; and fixing plates are arranged on the two sides of the water receiving box in the length direction, the fixing plates are wrapped with butyl rubber, and putty is smeared on the surface, making contact with a concrete structure of a tunnel,of the butyl rubber. The novel water interception system is simple in structure, the butyl rubber wraps the fixing plates on the two sides of the water receiving box, the putty is smeared on the butyl rubber, the water receiving box makes tight contact with the concrete structure, and the water intercepting effect is better while the water receiving box is firmly fixed.

Description

technical field [0001] The invention relates to the technical field of water interception devices for deformation joints, in particular to a new water interception system for deformation joints of subway tunnels. Background technique [0002] In recent years, the subway has quickly become the main public transportation for residents in large and medium-sized cities due to its fast, safe and stable characteristics. There are also more and more subway stations. Due to the different structural types of subway stations and sections, deformation joints are often designed at the interface between subway stations and sections to reduce the difference in deformation between stations and sections. The existence of deformation joints makes the interface of station sections a The hardest hit area of ​​subway leakage. [0003] With the subway equipment becoming more and more sophisticated, and even the arrival of unmanned subways, a small amount of groundwater may cause the paralysis o...

AI Technical Summary

Problems solved by technology

[0004] The existing water receiving box is a layer of stainless steel plate fixed by screws. Since both the screw and the steel plate are made of steel, there must be seams in the contact position, resulting in the problem of poor water interception effect of the water receiving box.
