Prefabricated single-compartment municipal utility tunnel

Abstract

The invention relates to a prefabricated single-compartment municipal utility tunnel. The prefabricated single-compartment municipal utility tunnel comprises a plurality of prefabricated duct pieces arranged on a concrete cushion layer, wherein longitudinal male rings and longitudinal female grooves are correspondingly and fixedly connected to the two end surfaces of the prefabricated duct pieces,and the longitudinal male rings and the longitudinal female grooves of adjacent prefabricated duct pieces mesh with each other; the longitudinal male rings comprise connecting rings and cylinders with circular cross sections, wherein one ends of the connecting rings are fixedly connected to the side surfaces of the cylinders, the other ends of the connecting rings are fixedly connected to the endsurfaces of the prefabricated duct pieces, and the thickness of the connecting rings is smaller than the diameter of the cylinders; and the longitudinal female grooves comprise cylindrical cavities accommodating the cylinders and connecting holes in which the connecting rings are inserted, the connecting holes communicate with the cylindrical cavities, elastic water stop strips are arranged on the two inner walls of the connecting holes, and the distance between the two water stop strips is smaller than the thickness of the connecting rings. The cylinders are connected into inner cavities ofthe longitudinal female grooves in a clamped mode to improve the connection convenience and adaptability of the longitudinal male rings and the longitudinal female grooves; and the water stop strips abut against the surfaces of the connecting rings in a pressing mode, and the waterproof effect between the adjacent prefabricated duct pieces can be enhanced.

Description

technical field [0001] The invention relates to the technical field of prefabricated and assembled municipal space structures and construction, in particular to a prefabricated and assembled single-chamber municipal comprehensive pipe gallery. Background technique [0002] With the growth of population and the development of economy in our country, it is accompanied by the planning and layout of various municipal pipelines. The number of various water supply, drainage, electricity, communication and other pipelines is increasing. Due to the lack of unified coordination and planning , The phenomenon of ground excavation and filling often occurs, which seriously affects the daily life of residents and the orderly operation of the city. The emergence of the municipal comprehensive pipe gallery has solved the above-mentioned problems that have plagued the government and citizens for many years. It can implement unified planning, design, construction and maintenance of various mu...

AI Technical Summary

Problems solved by technology

Although there is some research on the prefabricated structure of tunnels in subway sections in China, the research on the prefabricated structure of municipal comprehensive utility corridors is still in its infancy, and the waterproof technology is also in the experimental stage, and there are few engineering experiences that can be used for reference.
