Structure of utility tunnel and construction method

Abstract

The invention relates to a structure of a utility tunnel and a construction method. The structure of the utility tunnel comprises a bottom plate, prefabricated panels, reinforcement cages, reinforced structures and a top plate, wherein the bottom plate is formed by pouring; the prefabricated panels are arranged on the bottom plate; a cavity of which the top and the bottom communicate with each other is formed in each prefabricated panel; each reinforcement cage is inserted in the corresponding cavity; each reinforced structure is formed in the corresponding cavity by pouring; the top plate is formed on the prefabricated panels by pouring; the top plate and the reinforced structures are integrated by pouring; and the bottom plate, the prefabricated panels and the top plate are enclosed to form the utility tunnel. The prefabricated panels with the cavities are adopted, therefore, form boards of all wall boards in a cast-in-situ mode are omitted, and the width of an excavated foundation pit of the utility tunnel is not large; and by the bottom plate and the top plate which are cast in situ, mechanization and industrialization are realized to a maximum extent, and corresponding labor costs can be saved. The utility tunnel is lighter than an integral type prefabricated pipe gallery, the prefabricated panels with the cavities are light in weight and are convenient to hoist and convey, and therefore, large-area construction can be carried out in a construction site.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a structure and a construction method of an underground comprehensive utility gallery. Background technique [0002] The underground comprehensive pipeline corridor, also known as "common ditch" or "common pipeline", is the comprehensive corridor of underground urban pipelines. Build a tunnel space underground in the city, integrate various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage, etc., and set up special inspection ports, hoisting ports and monitoring systems, and implement unified planning, unified design, and unified Construction and management are the important infrastructure and "lifeline" to ensure the operation of the city. It is a municipal public facility that implements the same planning, design, construction and maintenance, and is built underground for laying municipal public pipelines. [0003] At presen...
