Fabricated underground structure and construction method

Abstract

The invention discloses a fabricated underground structure and a construction method. The problems that in the prior art, underground structure construction occupies a large space, and a large number of supporting structures are reserved are solved, and the beneficial effects that construction is convenient, the number of supporting structures is reduced, and environmental pollution is reduced are achieved. The fabricated underground structure comprises a plurality of sections, every two adjacent sections are connected, each section comprises side walls on the two sides, a bottom plate and a top plate, the bottom plates are arranged at the bottoms of the side walls, the top plates are arranged at the tops of the side walls, and each side wall comprises a plurality of prefabricated parts; and outward steps are formed on the side walls on the two sides of one end of each section, so that the other end, opposite to the steps, of the front section can be wrapped by the rear section, and every two adjacent sections are connected in a pouring mode.

Description

technical field [0001] The invention relates to the field of underground engineering, in particular to an assembled underground structure and a construction method. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Underground drainage, underground comprehensive pipe gallery, underground power tunnel and other projects are the main underground engineering construction contents in municipal construction. At present, the construction method of the main underground engineering structure adopts the open-cut and cast-in-place method. The inventor found that the cast-in-place method has the following problems: [0004] 1. The resource space of urban roads is limited, and the excavation of foundation pits takes up a lot of space, which will have a great impact on urban traffic during the construction period. [0005] 2. The foundation pit project...

AI Technical Summary

Problems solved by technology

[0004] 1. The resource space of urban roads is limited, and the excavation of foundation pits takes up a lot of space, which has a great impact on urban traffic during construction

[0005] 2. The foundation pit project has certain hidden dangers to the safety of buildings on both sides

[0006] 3. The excavation of the foundation pit produces a large amount of earthwork and leaves a large number of support structures in the soil, which causes pollution to the ecological environment and wastes resources

[0007] 4. The construction period of the cast-in-place structure is long, and the quality of the project is relatively unfavorable to guarantee

[0008] 5. The cast-in-place structure does not conform to the development situation of my country's industrialization

[0009] 6. There are also some assembled pipe galleries, but the assembled pipe galleries are prone to cracks at the joints, causing water leakage problems in the underground structure
