Large-section multi-cabin cast-in-place comprehensive pipe gallery top plate formwork construction system and construction method of large-section multi-cabin cast-in-place comprehensive pipe gallery top plate formwork system

Abstract

The invention provides a large-section multi-cabin cast-in-place comprehensive pipe gallery top plate formwork construction system and a construction method of a large-section multi-cabin cast-in-place comprehensive pipe gallery top plate formwork system. The large-section multi-cabin cast-in-place comprehensive pipe gallery top plate formwork construction system mainly comprises a movable top plate construction platform, movable top plate steel bar binding bed jigs, a top plate formwork erecting system and a top plate steel bar cage shaping support; adjustable opposite-jacking supporting rodsare erected on the upper portions of the adjacent pipe gallery side walls, a scaffold is erected on the foundation of the adjustable opposite-jacking supporting rods, and a pipe gallery top plate bottom mold is installed at the tops of the scaffold; the movable top plate steel bar binding bed jigs are symmetrically arranged on the two sides of the comprehensive pipe gallery, pipe gallery top plate steel bar binding construction is conducted through the movable top plate steel bar binding bed jigs, and a pipe gallery top plate steel bar cage is supported on the top face of the pipe gallery side walls through the shaping support; and top plate side molds are installed on the upper portions of the outer walls of the two ends of the pipe gallery outer side wall through opposite-pull screws, and top plate steel bar auxiliary operation and concrete pouring construction are conducted through the movable top plate construction platform. The large-section multi-cabin cast-in-place comprehensive pipe gallery top plate formwork system is easy to install, large in construction operation space, high in efficiency and good in benefit.

Description

technical field [0001] The invention relates to the technical field of foundation engineering, in particular to a construction system and a construction method for a roof formwork of a large-section multi-chamber cast-in-place comprehensive pipe gallery. Background technique [0002] The underground comprehensive pipe corridor is to gather all kinds of pipelines in the municipal infrastructure, such as electricity, communication, water supply, gas, heating, etc., for unified laying, management and maintenance. It not only solves urban traffic problems, but also greatly promotes the maintenance and operation of municipal services, and also has some functions of preventing natural disasters. [0003] At present, based on the analysis of engineering examples at home and abroad, in non-special environments, the main structure of the comprehensive pipe gallery is mainly divided into two types: cast-in-situ method and prefabricated method according to the construction method. The...
