Abstract

The invention relates to a semi-prefabricated pipe gallery. The semi-prefabricated pipe gallery comprises prefabricated side walls inserted in soil on the two sides of a to-be-excavated foundation pit, a pipe gallery bottom plate laid at the bottom of the to-be-excavated foundation pit, and a pipe gallery top plate arranged at the top of the foundation pit. The prefabricated side walls on the same side are arranged at intervals in the extension direction of the pipe gallery, and all the prefabricated side walls are connected through cast-in-place side walls poured on the inner sides of the prefabricated side walls. A pipe gallery space is formed by the prefabricated side walls, the cast-in-place side walls, the pipe gallery top plate and the pipe gallery bottom plate in an enclosed mode. The invention aims at providing the semi-prefabricated pipe gallery which can increase the engineering construction speed and improve the engineering construction quality. The semi-prefabricated pipe gallery has the advantages that 1, the site construction speed of the semi-prefabricated pipe gallery is high, the construction time is a fraction of the time required by a conventional construction scheme, thus, the investment recovery period is shortened, the overall cost input is reduced, and the economic benefits are obvious; and 2, the prefabricated side walls have the functions of foundation pit supporting, pipe gallery side walls, pipe gallery foundations and the like, and in addition, the prefabricated side walls can also be used as formworks during cast-in-place side wall construction, so that the overall engineering cost is reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a semi-prefabricated pipe gallery and a construction method. Background technique [0002] Underground comprehensive pipe gallery refers to the public tunnels used for centralized laying of municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heat, and gas underground in cities. my country's economically developed cities are mostly located in coastal soft soil areas. When constructing underground comprehensive utility corridors in these areas, the open cut method is often used, which requires soft soil foundation treatment and foundation pit support. Therefore, the construction of underground comprehensive utility corridors in soft soil areas requires high investment costs, long construction periods, and high construction risks. Contents of the invention [0003] One of the objectives of the present invention is to provide ...
