Assembled integral type subway station structure

Abstract

The invention discloses an assembled integral subway station structure which comprises a cast-in-place bottom plate, prefabricated side walls, a prefabricated top plate, a prefabricated middle plate, a prefabricated middle column, a middle longitudinal beam and a top longitudinal beam. The prefabricated side walls are arranged on the two sides of the cast-in-place bottom plate, and the prefabricated middle column is arranged on the middle side of the upper portion of the cast-in-place bottom plate; the top longitudinal beam and the middle longitudinal beam are arranged on the upper portion and the middle of the prefabricated middle column respectively, and the prefabricated middle column is a double-layer integrated segment column. According to the assembled integral type subway station structure, through organic combination of a prefabricated structure and cast-in-place and UHPC post-pouring at the joints, rigid connection of the joints is achieved, the structural integrity is good, safety and reliability are achieved, compared with full prefabrication, components are lighter, transportation and hoisting are convenient, the requirement for prefabrication and installation precision is low, the construction period can be shortened by 20%, and mold-free and support-free effects are basically achieved; and the on-site labor amount is reduced.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to an assembled integral subway station structure. Background technique [0002] At present, my country's urban underground engineering has entered a period of rapid development. In the construction of cast-in-place concrete structures, most of the work is done by manual labor, from scaffolding, formwork, tying steel bars to concrete pouring. There are many construction personnel, manual labor, high labor intensity, and high proficiency requirements; the construction speed is slow, the construction period is long, and it is greatly affected by natural conditions; the appearance and internal quality of concrete are difficult to control, the structure is poor in waterproofness, and the degree of mechanization is not high. higher. [0003] The present invention proposes an assembled and integrated subway station structure. First, factory-like structural comp...
