Pipe gallery formwork installation and construction technology

Abstract

The invention relates to a pipe galleries and discloses a pipe gallery formwork installation and construction technology. The pipe galleries and discloses a pipe gallery formwork installation and construction technology comprises the following construction process of conducting surveying, setting out and point fixation; assembling the formwork, conducting elevation adjustment, straightening, supporting and fixing; installing water stops and joint plate sealing rods; binding bottom steel bars and installing a wall reserved steel bar lifting formwork. According to the pipe gallery formwork installation and construction technology, formworks are fixed through split bolts, wall formworks on the two sides are always perpendicular to the bottom formwork in use, and therefore when formworks on the two sides bear squeeze from gravity, the side formworks are stabilized at the initial position by the bolts; by means of pull action of the split bolts, when steel bars between the two side wall formworks are detached, the wall formworks on the two sides are still perpendicular to the bottom formwork, the perpendicular error is kept in a standard range, so that when the two formworks on the twosides are used, a top formwork is supported through perpendicular force, in combination with connection between the formworks through the split bolts, the stability of the formworks on the two sides in use is further improved.

Description

technical field [0001] The invention relates to the technical field of underground pipe corridors, in particular to a construction process for installing formwork for pipe corridors. Background technique [0002] Comprehensive pipe gallery is the comprehensive corridor of underground urban pipelines, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports and hoisting ports and monitoring systems. [0003] The underground comprehensive pipe gallery system not only solves the problem of urban traffic congestion, but also greatly facilitates the maintenance and repair of municipal facilities such as electricity, communications, gas, water supply and drainage. In addition, the system also has a certain effect of earthquake prevention and disaster reduction. During the construction process of the existing underground comprehensiv...

AI Technical Summary

Problems solved by technology

In addition, the system also has a certain effect of earthquake prevention and disaster reduction. During the construction process of the existing underground comprehensive pipe gallery, most of them are directly hoisted by the formwork. First, the bottom formwork is laid, and then the two sides and the top formwork are laid. The formwork is completed Then use steel bars to weld the brackets to strengthen the stability of the pipe gallery. However, when the formwork is hoisted, most of them are directly installed on the bottom plate. One side is inclined, the limit steel bar at the bottom is bent, and the top plate itself has a certain weight when it is installed. The gravity acts on the formwork on both sides, resulting in a vertical difference between the formwork on both sides and the bottom plate. In severe cases, the formwork will be deformed and cracked. After the pipe gallery is cast, it cannot play the role of waterproof and moisture-proof. At the same time, after the formwork is installed, due to the removal of the limit steel bars in the middle of the formwork on both sides, the formwork is squeezed, and the phenomenon of mold expansion is prone to occur, resulting in The formed pipe gallery is squeezed inward by the formwork, and the space of the pipe gallery becomes smaller, causing the formwork to squeeze the internal lines of the pipe gallery, and the lines are damaged by force, and in severe cases, breakage occurs, which further affects the use of the pipe gallery
