Crossroad underground walkway and comprehensive pipe rack co-construction structure and construction method thereof

Abstract

The invention relates to a crossroad underground walkway and comprehensive pipe rack co-construction structure and a construction method thereof. The co-construction structure comprises three layers of main body section structures; the upper layer of main body section structure is of an underground walkway single-cabin structure, and communicates with four access ports through four sections of upper-layer gradient change connecting sections; the middle layer of main body section structure is of a double-cabin structure of a comprehensive cabin and a gas cabin; the bottom layer of main body section structure is of a double-cabin structure of a comprehensive cabin and an electric cabin; the upper layer of main body section structure and the middle layer of main body section structure, and the middle-layer main body section structure and the bottom layer of main body section structure communicate through ladder channels; the two ends of the bottom layer of main body section structure communicate with bottom-layer gradient change connecting sections; and after the bottom-layer gradient change connecting sections are gradually changed, the elevation is consistent with the elevation of the middle layer of main body section structure. Under the precondition of guaranteeing relative independent arrangement of all municipal pipelines in a comprehensive pipe rack, the co-construction structure meets the pedestrian passing and comprehensive pipe rack maintenance demands, and fully uses the underground space structure to reduce the construction cost.

Description

Technical field [0001] The invention belongs to the technical field of construction of underground sidewalks and underground comprehensive pipe corridors, and particularly relates to a joint construction structure of underground sidewalks and comprehensive pipe corridors at intersections and a construction method thereof. Background technique [0002] The comprehensive pipe gallery is to build a tunnel space underground in the city, integrating power, communication, gas, heating, water supply and drainage and other engineering pipelines. It is equipped with special inspection ports, hoisting ports and monitoring systems, implementing unified planning, Unified design, unified construction and management are important infrastructure and "lifeline" to ensure the operation of the city. [0003] The development of the integrated pipe gallery has a history of nearly a hundred years. At the same time, according to the design specifications of the integrated pipe gallery, the integrated pi...

Problems solved by technology

[0004] However, the traditional pipe gallery intersection can only realize the cross connection of various pipelines, does not have the function of pedestrian passage, and cannot meet the requirements for the maintenance of comprehensive pipe gallery access
