Industrially constructed underground station structure and construction method

Abstract

The invention provides an industrially constructed underground station structure. The industrially constructed underground station structure comprises a cast-in-place bottom plate, prefabricated side walls, first U-shaped cross beams, second U-shaped cross beams, top beams, first longitudinal beams, second longitudinal reversed beams, prefabricated stand columns, longitudinal anchor cables, first transverse anchor cables and second transverse anchor cables. Only the side walls, the U-shaped cross beams and the stand columns with square outlines need to be prefabricated, components with various lengths can be prefabricated by adjusting the relative positions of end molds so as to meet the requirement of the complex industrially constructed underground station structure of urban rail transit in mountainous areas, the mold cost is low, the prefabrication and installation industry is simple, and additionally, transverse tensioning and longitudinal tensioning of the anchor cables are adopted, so that all the prefabricated components are integrally connected, the integrity of the station structure is guaranteed, the anchor cables further have the function of bearing the later load of a station, the anchor cables are integral connecting components and bearing components of the later load of the structure, and the performance of the anchor cables is brought into full play.

Description

technical field [0001] The invention relates to the field of underground engineering construction, in particular to an industrialized construction of an underground station structure and a construction method. Background technique [0002] During the construction of existing subway stations, prefabricated assembled components are currently used (for the specific structure, please refer to the Chinese utility model patent "prefabricated assembled subway station component assembly vehicle" and its attached parts with the publication number CN204984433U figure 1 ), the prefabricated assembly structure has 7 pieces per ring, including 3 pieces of cast-in-place bottom plates, 2 pieces of side walls, and 2 pieces of top plates. The width of the ring is 2m. Blocks and blocks, rings and rings are all connected by tenon joints and tightened with precision-rolled rebar. It is a point connection, and the overall stability is poor. It is not applicable in some areas; each component is ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the industrialized underground station structure and construction method provided by the present invention solve the problem that the subway station adopts a prefabricated assembly structure, there are many types of prefabricated components and complex outlines, the cost of molds is high, and tenon joints and finish rolling are used. The connection method of threaded steel is tightened, and the technical problems of poor overall stability; at the same time, it also solves the problems of manufacturing and installation accuracy, difficult construction, and joint waterproof durability that cannot meet the 100-year design
