Method for reinforcing and constructing template of deformation joint of comprehensive pipe gallery structure

Abstract

The invention discloses a method for reinforcing and constructing a template of a deformation joint of a comprehensive pipe gallery structure. The construction method comprises the following construction steps that firstly, template closing construction on the inner template and the outer template of the shear wall is performed, water stop screw rods are temporarily unfastened, and opposite-pulling water-stopping screw rod penetrates through the shear wall; then, middle-buried rubber water stop belt at the deformation joint of the shear wall is installed, the templates on the two sides of themiddle-buried type rubber water stop belt are plugged between the middle-buried water stop belt, the inner template and outer template, and the inner and outer opposite-pulling water-stopping screw rods are fastened; and finally, the lateral templates on the two sides of the middle-buried water stop belt are supported and reinforced by using a sizing steel supporting bracket, the sizing steel supporting bracket and a longitudinal steel pipe keel of the shear wall are connected into a whole, and the concrete lateral template reinforced at the deformation joint of the shear wall is completed. According to the method, a conventional wood square support is replaced by the sizing steel supporting bracket, the reinforcing supporting bracket at the deformation joint of the shear wall and the longitudinal steel pipe keel of the shear wall are ingeniously connected into a whole, the deformation, the deflection and the instability of the lateral support member are prevented, and concrete forming effect is good after being used for fixing the mounting process.

Description

technical field [0001] The invention belongs to the field of building and infrastructure construction, and in particular relates to a formwork reinforcement construction method at deformation joints of a comprehensive pipe gallery structure. Background technique [0002] At present, the country is vigorously constructing urban underground comprehensive pipe corridors nationwide. According to the requirements, a vertical deformation joint of the shear wall must be installed for every length of the comprehensive pipe corridor not exceeding 30m, and a buried rubber waterstop is generally provided. The quality of the concrete construction at the vertical deformation joint will play an important role in controlling the overall waterproof effect and uneven settlement of the pipe gallery. However, due to the setting of the buried rubber waterstop, the deformation joint of the shear wall will It is more difficult to reinforce the formwork at the place, especially the outer support o...

Problems solved by technology

[0004] In order to solve the problem of formwork reinforcement at the deformation joints of the shear wall of the urban comprehensive utility gallery and improve the quality of concrete pouring, the invention provides a construction method for strengthening the formwork at the deformation joints of the comprehensive utility gallery structure, that is, the lateral formwork at the deformation joints of the shear wall is adopted The shaped steel support supports and fixes the lateral formwork, which solves the problems of difficulty in reinforcing the lateral formwork at the deformation joint, poor stability, easy mold expansion, slurry leakage, and lack of vibration. The longitudinal formwork support system of the shear wall is formed as an integral support system, which makes the lateral formwork reinforcement at the deformation joints very firm and stable, and has a wide range of practical promotion value
