Technical Field
The utility model relates to a municipal transportation design and construction field especially relate to a subway station and viaduct co-construction structure of bias voltage.
Background
In order to relieve the situation that urban traffic is increasingly tense, a three-dimensional traffic mode formed by underground rail traffic, ground urban roads and ground viaducts is adopted by more and more cities. When the plane lines of the subway station and the ground viaduct are overlapped, two structural schemes of station-bridge separation and station-bridge co-location combined construction are generally adopted.
The station-bridge separation means that the structures of a subway station and a ground viaduct are mutually independent and completely separated, and specifically, the two schemes are as follows: in the first scheme, platforms of a subway station are separated, a separation island type platform or a separation side type platform is adopted, and a viaduct pile foundation is positioned in the middle of the subway station; scheme two, overpass gate-type pier scheme, subway station sets up and the overpass pile foundation promptly between, overpass adopts gate-type pier to span subway station.
The station-bridge co-location co-building means that a subway station and an viaduct are longitudinally arranged in parallel, viaduct piers are arranged on a station top plate, the pier positions correspond to the subway station structure column directions, and the piers and upper loads are directly transmitted to a station bottom plate through the station structure column and then transmitted to a foundation.
