A full-section support-free composite composite pipe gallery structure and construction method

Abstract

The invention relates to a full-section support-free laminated assembly-type comprehensive pipe gallery structure and a construction method. The inner panel of the wall and the outer panel of the side wall are composed of tie reinforcement bars between the inner panel of the side wall and the outer panel of the side wall; The lower end of the board is provided with reserved protruding steel bars, and the inner wall board is formed by superimposing two wall boards; the present invention aims at the vertical support interference construction, the difficult construction of the armpit corners, and the slope of the installation site in the existing integrated integrated pipe gallery technology In view of the limitations and other problems, a method of exempting vertical support for the assembly of integral concrete pipe gallery is provided. This method mainly adopts self-designed stiffened axillary corner pouring formwork, combined with structural adjustment of wall panels to realize support-free installation, and at the same time solves the problem of axillary corner pouring template.

Description

technical field [0001] The invention relates to the technical field of municipal construction comprehensive pipe gallery, in particular to a full-section support-free superimposed and assembled comprehensive pipe gallery structure and a construction method. Background technique [0002] The technology of assembling integral concrete pipe gallery is in line with the development of construction industrialization and is constantly being developed and improved. Assembling the integral concrete pipe gallery technology realizes the construction method of "factory processing of components and on-site assembly of structures". By splitting into prefabricated components such as prefabricated floor, prefabricated roof, and prefabricated wall panels, problems such as heavy prefabricated pipe gallery components and inconvenient assembly are avoided. , At the same time, it solves the problem of joint waterproofing, greatly improves the construction quality and efficiency, and realizes gre...

AI Technical Summary

Problems solved by technology

The cast-in-place construction of the axillary corner is mainly formed by wooden formwork and steel pipe support. First, a certain amount of support needs to be added, which increases the difficulty of construction; In the application of the assembly of integral concrete pipe gallery, there is even a design that cancels the axillary angle for the convenience of construction

The existing assembly-integrated integrated pipe gallery technology has problems such as vertical support interference construction, difficult construction at the axillary corner, and restrictions on the slope of the installation site, which restrict the application and promotion of the assembled integrated concrete pipe gallery technology. It is necessary to design an assembled integrated integrated pipe gallery gallery
