Full-fracture surface supporting-free overlapped fabricated type comprehensive pipe gallery structure and construction method

Abstract

The invention relates to a full-fracture surface supporting-free overlapped fabricated type comprehensive pipe gallery structure and a construction method. The structure comprises a fabricated overlapped top plate, a fabricated overlapped base plate, a fabricated side wall plate and a fabricated inner wall plate; the side wall plate is formed by a side wall inner sheet plate and a side wall outersheet plate, and steel tie bars are arranged between the side wall inner sheet plate and the side wall outer sheet plate; and the upper and lower ends of the side wall inner sheet plate are provided with reserved extending-out reinforcing steel bars, the lower end of the side wall outer sheet plate is provided with reserved extending-out reinforcing steel bars, and the inner wall plate is formed by overlapping two wall plates. A vertical-support-free method for assembling an overall concrete pipe gallery is provided for solving the problems that an existing technology for assembling the overall comprehensive pipe gallery has the problems that a vertical support has interference in construction, axillary corner construction is difficult, and the installing field slope limitation exists; andaccording to the method, a self-designed stiffened axillary corner pouring formwork is mainly adopted, and the formwork capable of achieving supporting-free installation and capable of solving the problem about axillary corner pouring is achieved in cooperation with wallboard structure construction adjustment.

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
