Construction Technology of Pipe Gallery in Loess Layer

Abstract

The invention discloses a loess layer pipe gallery construction technology. The loess layer pipe gallery construction technology carries out construction according to the following steps that a foundation groove with the vertical surface gradient being 90 degrees is formed in a loess covering layer in an excavation mode, and a plurality of module box bodies which are fastened and connected are sequentially manufactured and formed in the length direction of the foundation groove to form a loess layer pipe gallery; and a cement soil stabilization layer and a concrete cushion layer bottom plate are sequentially laid on the bottom surface of the foundation groove, an outer wall top formwork is installed and formed on the concrete cushion layer bottom plate, concrete is poured to form a concrete cushion layer side plate, a bottom surface steel bar assembly is manufactured and formed on the surface of the concrete cushion layer bottom plate, concrete is poured to form a reinforced concrete bottom plate, an inner wall top formwork is installed and formed on the reinforced concrete bottom plate, concrete is poured to form a reinforced concrete side plate, a support top formwork is installed and formed on the reinforced concrete bottom plate, and concrete is poured to form a reinforced concrete cover plate. The loess layer pipe gallery construction technology has the advantages of being simple in process, good in pipe gallery forming quality, low in construction cost, and high in construction efficiency.

Description

technical field [0001] The invention relates to the field of pipe gallery construction, in particular to a construction process for a loess layer pipe gallery. Background technique [0002] The 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, hoisting ports and monitoring System, the implementation of unified planning, unified design, unified construction and management, is an important infrastructure and "lifeline" to ensure the operation of the city. It is a municipal public facility that implements unified planning, design, construction and maintenance, and is built underground in the city for laying municipal public pipelines. [0003] The construction of the traditional pipe gallery adopts large-scale excavation of the sloping formwork fou...

AI Technical Summary

Problems solved by technology

[0003] The construction of the traditional pipe gallery adopts large-scale excavation of the sloping formwork foundation groove, which requires a large number of skilled masons to complete the construction of the pipe gallery with wooden frame formwork, concrete pouring, and formwork removal. The precision of the pipe gallery is low, and the wall surface of the pipe gallery Rough, consumes a lot of manpower and materials, and the current construction market has a tight and aging labor force, a shortage of mud carpenters, and a tight construction period
