Cast-in-situ comprehensive pipe gallery and construction method

Abstract

The invention relates to a cast-in-situ comprehensive pipe gallery and a construction method. The cast-in-situ comprehensive pipe gallery comprises a base slot excavation bottom elevation located at the bottom of a foundation trench and an original ground current elevation located at the top of the foundation trench. A cast-in-situ comprehensive pipe gallery formwork system and cast-in-situ comprehensive pipe gallery foundation trench supporting systems located on the two sides of the cast-in-situ comprehensive pipe gallery formwork system are arranged on the base slot excavation bottom elevation. Each cast-in-situ comprehensive pipe gallery foundation trench supporting system comprises an excavation slope, wherein a plurality of foundation trench supporting devices are formed on the excavation slope at equal intervals. A prefabricated drainage ditch which can be used repeatedly is formed in the base slot excavation bottom elevation and is located between the excavation slope and cast-in-situ comprehensive pipe gallery formwork system. According to the cast-in-situ comprehensive pipe gallery and the construction method, a prefabricated retention wall assembled by grooves and tongues is arranged on the top surface of the foundation trench, a channel steel frame is arranged on the outer side of the retention wall, and a propaganda board can be placed in the channel steel frame; and through the structure, the propaganda board can be replaced conveniently, and construction is simple and rapid.

Description

technical field [0001] The invention relates to the technical field of construction of a comprehensive pipe gallery, in particular to a cast-in-place comprehensive pipe gallery and a construction method. Background technique [0002] With the rapid development of my country's economic construction and the increase of urban population, the scale of cities continues to expand, and many cities have problems such as shortage of construction land, road traffic congestion, insufficient urban infrastructure, and increased environmental pollution. The solutions to these problems are as follows: one is to continue to expand the urban extension, and the other is to take the road of connotative development and put the development and utilization of urban underground space on the agenda. The extensional development method relies on expanding the urban land area and extending to high altitudes. On the one hand, the urban population density increases and the urban capacity expands sharply...

AI Technical Summary

Problems solved by technology

[0004] The tonnage of the traditional prefabricated pipe gallery is huge, and the requirements for hoisting and transportation equipment are high; on the other hand, the overall prefabricated mold is complex, the production efficiency is average, and the site is occupied during the construction period; during the excavation of the foundation pit, horizontal supports need to be set separately, which is cumbersome to install and disassemble. The construction cost is increased, and the quality is difficult to guarantee
