Subway station active and passive anti-floating structure and design, construction and use method thereof
The invention provides a subway station active and passive anti-floating structure which comprises an active anti-floating device and a passive anti-floating device, the active anti-floating device comprises a water guide ditch, a water filter pipe, an overflow pipe, a water collecting pipe, a pre-buried water drainage pipe, a water drainage pipe and a water collecting pit, and the water guide ditch and the water filter pipe are arranged between a subway station bottom plate and a rock-soil foundation; the overflow pipe is fixed to the inner side of the fender post, the water collecting pipe and the pre-buried drainage pipe are arranged in the side wall of the subway station, and the sewer pipe and the sump are located in the subway station. The passive anti-floating device is an uplift pile. According to the pressure-limiting drainage active anti-floating device, only buoyancy under the high water level in the wet water period is removed, the water level is controlled to be below the pressure-limiting water level line, water is drained in a time-limiting and quantity-limiting mode, and sedimentation of surrounding buildings and roads cannot be caused; meanwhile, the passive anti-floating device designed according to the pressure limiting water line can greatly reduce the use amount of uplift piles, reduce the manufacturing cost and realize the unification of the safety and the economical efficiency of the subway station.
本发明提供了一种地铁车站主被动抗浮结构，包括主动抗浮装置和被动抗浮装置，主动抗浮装置包括导水沟、滤水管、溢流管、汇水管、预埋排水管、下水管和集水坑，导水沟和滤水管设置在地铁车站底板与岩土地基之间，溢流管固定于围护桩内侧，汇水管和预埋排水管内置于地铁车站侧墙中，下水管和集水坑位于地铁车站内部。被动抗浮装置为抗拔桩。本发明限压排水主动抗浮装置仅卸除丰水期高水位下的浮力，既将水位控制在限压水位线以下，又限期限量排水、不会引起周边建筑和道路的沉降；同时，依据限压水位线设计的被动抗浮装置可大大减少抗拔桩的用量、降低造价，实现地铁车站安全性与经济性的统一。
