Embodiment 1

[0075] Example 1, project overview: The second phase of the integrated pipe gallery project in the start-up area of ​​an international low-carbon city in a city is the construction of a comprehensive pipe gallery and related roads.

[0076] The relocation and restoration project of the pipeline is about 1406.6 meters long and has four pipeline cabins. The pipe gallery is arranged under the lanes, sidewalks and green belts of the existing roads.

[0077] The buried depth of the base of the pipe gallery is about 8.0m. Because the pipe gallery is close to municipal roads and villagers’ buildings, in order to protect the existing roads, existing underground pipelines and existing villagers’ buildings, the comprehensive pipe gallery foundation pit cannot be constructed in the form of large excavation, and must be erected. Support measures. In order to strictly control the deformation of the foundation pit and the fall of groundwater, and try to avoid social influence, the foundati...

Abstract

The invention discloses an open-cut cast-in-place underground comprehensive pipe gallery movable bench formwork integrated construction method. The method comprises the following steps that S1, construction operation is determined through monitoring measurement; s2, construction preparation is conducted, and movable bench formwork bottom plates are externally spliced; s3, construction of a bottom plate of the segment pipe gallery; s4, a formwork system is adjusted, and steel bars are manufactured and bound; s5, an equipment outer formwork and an embedded part are installed, and a settlement joint or a construction joint is installed; s6, wall body and bottom plate concrete pouring is conducted, and concrete is cured; s7, the movable bench formwork is demolded, the outer formwork is dismantled, and the formwork is cleaned; step S8, constructing a waterproof layer; step S9, backfilling the foundation pit; by the adoption of the overall supporting and disassembling construction technology of the movable bench formwork, repeated assembling and disassembling of a top plate scaffold and a formwork are avoided, the effect is improved, the construction period is greatly shortened, and the method has obvious social benefits and economic benefits and has application and popularization value.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an integrated construction method of a mobile table formwork for an open-cut and cast-in-place underground comprehensive pipe gallery. Background technique [0002] In order to make intensive use of urban construction land, improve the safety and standards of urban engineering pipeline construction, and make overall arrangements for the laying of urban engineering pipelines in the comprehensive pipe gallery, it can ensure that the construction of the urban comprehensive pipe gallery project is applicable, economical, reasonable, technologically advanced, and convenient for construction and construction. maintain. The integrated pipe gallery integrates various engineering pipelines such as electricity, communication, gas heating, water supply and drainage, and has special inspection ports, hoisting ports and monitoring systems. The implementation of unified planning, unified ...
