Subway station and road viaduct beam combined construction section structure

Abstract

The invention discloses a subway station and road viaduct beam combined construction section structure. The structure at least comprises a road viaduct beam body, road viaduct piers, a rail transit station and road viaduct shared enclosure structure, a rail transit station and road viaduct bearing platform shared structure body, a road viaduct and rail transit station shared pile foundation and aground road. The rail transit underground station and the road overhead are jointly built and arranged through the rail transit station and road viaduct shared enclosure structure and the road viaductbearing platform shared structure body; both the road elevated road and the rail transit underground station can be arranged in the middle of the road, the net width of the projection surface of theelevated road and the underground structure is only 30m, the road width is more than 40m, the occupied area is small, and the engineering cost is low. The subway station and road viaduct beam combinedconstruction section structure is particularly suitable for being arranged on roads with narrow red lines, large-area demolition of ground buildings can be avoided, and the engineering implementationdifficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of urban traffic road construction, in particular to a cross-sectional structure jointly built by subway stations and road viaducts. Background technique [0002] refer to figure 1 : because rail transit lines and urban expressways all should be arranged on the wider city road of red line, often occur the situation that road viaduct and rail transit underground line are arranged on a road. At present, the elevated road and the rail transit station are constructed separately. The distance between the elevated cap and the underground rail transit station is generally more than 3m. Generally, the road elevated is arranged in the middle of the road, and the rail transit underground station is arranged on one side of the elevated cap of the road. The net width of the projected surface of the structure needs to be more than 45m, and the width of the road needs to be more than 60m to be conditionally arranged. Th...

Problems solved by technology

At present, the elevated road and the rail transit station are constructed separately. The distance between the elevated cap and the underground rail transit station is generally more than 3m. Generally, the road elevated is arranged in the middle of the road, and the rail transit underground station is arranged on one side of the elevated cap of the road. The net width of the projected surface of the structure needs to be more than 45m, and the width of the road needs to be more than 60m to be conditionally arranged. Project implementation brings great difficulties
