Superimposed assembled type underground pipe gallery system and construction and manufacturing process

Abstract

The invention provides a superimposed assembled type underground pipe gallery system and a construction and manufacturing process. A bottom plate is a cast-in-place bottom plate on an underground pipe gallery cushion layer, side walls and a middle wall body are prefabricated sandwich superimposed walls, a top plate is a prefabricated superimposed plate, and the bottom plate, the side walls and the middle wall body and the top plate are connected into an overall underground pipe gallery in a cast-in-place mode. According to the novel underground pipe gallery technology system, part is subjected to prefabrication in a factory, part is subjected to on-site superimposed cast-in-place, advantages of prefabrication in the factory and on-site cast-in-place are fully played, defects and disadvantages of prefabrication in the factory and on-site cast-in-place are overcome, particularly defects that a traditional superimposed pipe gallery is low in production efficiency and small in transport quantity are overcome, on-site template-free construction is achieved, environmentally friendliness and energy conservation are achieved, efficiency is high, and excellent waterproof performance is achieved.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering, and in particular relates to a superimposed and assembled underground pipe gallery system and a construction process. Background technique [0002] The Guiding Opinions of the General Office of the State Council on Promoting the Construction of Urban Underground Comprehensive Pipe Gallery (Guobanfa [2015] No. 61) was announced on August 10, 2015. The goal is to build a number of internationally advanced underground comprehensive pipeline corridors and put them into operation by 2020. The problem of "road zippers" caused by repeated excavation of the ground has been significantly improved, the safety level of pipelines and the ability to prevent and resist disasters have been significantly improved, and the main Street spider web-like overhead lines, the city's ground landscape has improved significantly. The construction of underground comprehensive pipe corridors in various provin...
