Water stop clamping tool, tunnel longitudinal water stop structure and construction method

Abstract

The invention relates to the technical field of tunnel construction, in particular to a water stop clamping tool, a tunnel longitudinal water stop structure and a construction method. The water stop clamping tool comprisesa fixing part for mounting on a tunnel side wall template, and a connecting part connected with the fixing part and extending to be above a concrete pouring area; the connectingpart is provided with a mounting structure for connecting with a metal-plate-shaped water stop, and the relative position between the water stop and the connecting part can be adjusted, so that the water stop corresponds to a construction joint after the water stop is connected with the connecting part. The water stop clamping tool is arranged on an inverted arch trestle template, water stop partsare fixed by the connecting part, and the effective adjustment is carried out through the connecting part, thereby solving the problem of difficulty in positioning; and the water stop parts are changed to solve the problems of severe distortion and inconvenience in splicing of the existing water stop parts and achieve the purposes of accurate positioning, straightness and no distortion, and convenient connection of the water stop parts, and the construction quality and the construction safety of the tunnel waterproof construction are ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a waterstop fixture, a tunnel longitudinal waterstop structure and a construction method. Background technique [0002] In the process of tunnel construction, tunnel waterproof construction is a very important link. If the waterproof construction process is not done well, not only during the tunnel construction process, but also after the tunnel is put into use later, there will be problems of water seepage and waterlogging, which will seriously affect the engineering quality of the tunnel. [0003] The water seepage problem of the tunnel mainly occurs at the construction joints. During the gradual pouring process of the side walls of the tunnel from bottom to top, there will be horizontal transverse joints. The transverse joints extend along the longitudinal direction of the tunnel and their length is The length of the pouring section, in order to avoid water seepag...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to solve the problems of difficult positioning, severe distortion and inconvenient splicing when waterproof woven fabric or waterproof rubber strip is used as the longitudinal water-stop structure of the tunnel in the prior art, which leads to poor longitudinal water-stop effect of the tunnel and easy occurrence of water seepage In order to solve the problems that affect the quality and safety of the project, a waterstop fixture, a tunnel longitudinal waterstop structure and a construction method are provided. The water-stop parts are clamped and fixed, and the position of the water-stop parts is effectively adjusted through the connecting part, thus solving the problem of difficult positioning. At the same time, changing the water-stop parts solves the serious distortion and inconvenient splicing of the existing water-stop parts To solve the problem, the water-stop parts can be firmly fixed by the water-stop clamp, so as to achieve the purpose of accurate positioning, straightness without distortion and convenient connection of the water-stop parts, so as to ensure the engineering quality and engineering safety of the tunnel waterproof construction
