Problems solved by technology

[0003] In order to solve the problem that the upright column is arranged in the middle of the platform in the current structural design of the subway station, resulting in the underutilization of the platform space of the subway station, the present invention provides a construction method for a double-deck, three-span subway station structure with arched shear walls, This structural form not only makes full use of the platform space of the subway station, but also enables both sides of the screen door structure to be installed on the main structure of the station, increasing its stability

Embodiment Construction

[0031] Below to Figure 1-7 As an example, the present invention will be specifically described.

[0032] figure 1 , the internal load-bearing structure of the subway station structure is a 3000mm×700mm concrete-filled steel pipe shear wall 1, which is set on the edge of the platform slab 5, and the distance between two adjacent concrete-filled steel pipe shear walls 1 along the longitudinal direction of the subway station is B The length of a compartment of a large subway train is 19520mm, the length of the CFST shear wall 1 is 3000mm, and the thickness is 700mm.

[0033] figure 2 ,because figure 1 The longitudinal span between two adjacent CFST shear walls 1 is relatively large, so the CFST arch frame 2 structure is adopted to ensure the structural bearing capacity, and the CFST arch frame 2 is arranged between two adjacent CFST shear walls 1 In between, the arch foot is set on the concrete-filled steel tube shear wall 1, the thickness of the concrete-filled steel tube ...

Abstract

The invention relates to an arch scaffolding shearing force wall type double-layer three-span subway station structure and a construction method, and belongs to the field of open cut subway station design and construction. According to the structural style, an arch scaffolding shearing force wall structure is used as an internal load bearing system and is arranged on the edge of a platform. The distance between two adjacent sections of shearing force walls in the subway station direction is the length of a subway train carriage, an arch scaffolding structure is arranged between every two adjacent sections of shearing force walls, arch springs are arranged on special-shaped columns, spandrel columns are evenly arranged on the arch scaffolding structures, and arch tops and the spandrel columns directly support middle plates or top plates. A shielding door structure is mounted between every two adjacent sections of shearing force walls additionally, the two sides of the shielding door structures are mounted on the shearing force walls, and the lower portions of the shielding door structures are mounted on platform plates.

Description

technical field [0001] The invention relates to a construction method of a subway station structure, in particular to a construction method of an arch shear wall type double-deck and three-span subway station structure, which belongs to the field of open-cut subway station design and construction. Background technique [0002] At present, the main structure design of most subway stations in my country adopts the double-layer three-span island platform structure, and the internal load-bearing structure is a beam-slab-column frame structure. Usually the column is set in the middle of the platform, and only the longitudinal beam is set on the column, and the cross beam is not set. The longitudinal spacing of columns is usually 6m to 8m, and there are cases where the column spacing is increased to more than 9m, and the horizontal spacing is 6m. The uprights are at a certain distance from the edge of the platform. Compared with the two-span or single-span form, this structural ...
