Template structure of utility tunnel guide wall, and erection method

Abstract

The invention provides a template structure of a utility tunnel guide wall which belongs to the field of tunnel construction, and aims to provide the template structure of the utility tunnel guide wall, and an erection method which can realize convenient assembly and disassembly, increase turnover efficiency and guarantee construction quality. The structure comprises a concrete cushion and is characterized by comprising a guide wall outer template which is vertically fixed on the concrete cushion, at least one bottom face template which is disposed on the inner side of the guide wall outer template, disposed at a position facing the concrete cushion, and disposed horizontally above the concrete cushion, as well as a guide wall inner template disposed on each of the bottom face templates, wherein the guide wall outer template comprises a plurality of aluminum alloy outer template units which are distributed longitudinally along a tunnel, and a connecting part used for docking every twoadjacent outer template units, and a guide mechanism, a supporting mechanism and a motion mechanism are disposed on the outer side of each of the outer template units. The template structure of the utility tunnel guide wall, and the erection method provided by the invention have the beneficial effects that assembly and disassembly of the tunnel guide wall outer template are convenient; phenomena of slurry leak and template expansion are relieved, and use stability of the template is enhanced; and because of the erection method, fewer construction workers are needed, turnover efficiency of theouter template units is increased, and template mounting time is shortened.

Description

technical field [0001] The invention belongs to the field of pipe gallery construction, and in particular relates to a formwork structure and an erection method for a guide wall of a comprehensive pipe gallery. Background technique [0002] As a construction facility built underground in the city to accommodate urban engineering pipelines, the pipe gallery is an important part of urban infrastructure construction. The comprehensive pipe gallery, that is, a common ditch and a common pipeline, is a tunnel space built underground in the city. Communication, gas, heating, water supply and drainage and other engineering pipelines are integrated to achieve unified planning. [0003] At present, two pourings are usually used in the construction of the pipe gallery, that is, from the bottom to the top, the lower part of the guide wall is poured first, and then the remaining part is poured. When the guide wall is poured, the outer formwork is mostly made of wood formwork, aluminum...

AI Technical Summary

Problems solved by technology

Among them, the wooden formwork requires more supporting components; it takes a long time to set up and remove the formwork, and the turnover efficiency is low; the erection, transfer and disassembly of the formwork all require more labor costs; Phenomena such as slurry leakage and mold expansion are prone to occur, resulting in poor molding effect after mold removal, and common quality problems such as wrong platform, honeycomb, and pockmarked surface are prone to occur

Wood-plastic molds also require more labor costs and supporting components; the turnover efficiency is low; and their rigidity is poor, and mold expansion is prone to occur during pouring, and the molding effect is average

Due to the outstanding turnover characteristics and good construction quality of aluminum formwork, it has broad market prospects in the application of large-scale pipe gallery standard section structures, but aluminum formwork also requires more labor; the turnover speed is slightly faster than wooden formwork, but the overall efficiency is not good. high
