Rainwater injection prevention mechanism suitable for subway station entrance
A rainwater injection prevention mechanism suitable for a subway station entrance comprises an inspection well arranged at the subway entrance, a supporting plate is fixedly installed in the middle of the inspection well, a cover plate flush with the ground is arranged above the supporting plate, a port of the inspection well is divided into a water drainage port and a lifting port through the cover plate, and the lifting port is located on the side close to the subway entrance. The drainage port is communicated with an external drainage official website through a drainage channel, and a grate is arranged above the drainage port; sliding rails are arranged on the walls on the two sides corresponding to the lifting opening respectively, a floating box capable of moving up and down along the sliding rails is installed on the sliding rails, a sealing assembly is installed between the floating box and the lifting opening in a matched mode, and limiting assemblies used for limiting the ascending limit position and the descending limit position of the floating box are further arranged on the upper side and the lower side of the floating box respectively. The inspection well is divided into the drainage port and the lifting port through the cement board, the buoyancy box located at the lifting port automatically seals the entrance of the subway station through buoyancy when heavy rain occurs, and rainwater is effectively prevented from being poured into the subway station.
一种适用于地铁站入口的防雨水灌入机构，包括设置在地铁入口处的窨井，在窨井的中部固定安装有支撑板，在支撑板上方设有与地面平齐的盖板，通过盖板将窨井的端口分隔为排水口和升降口，所述升降口位于靠近地铁入口的一侧，所述排水口通过排水通道连通外部排水官网，在排水口上方设有篦子；对应升降口的两侧墙壁上分别设有滑轨，在滑轨上安装有可沿滑轨上下移动的浮箱，所述浮箱与升降口之间配合安装有密封组件，在所述浮箱的上下两侧还分别设有用于限定浮箱上升极限位置和下降极限位置的限位组件。本发明通过水泥板将窨井分隔成排水口和升降口，处于升降口的浮箱遇有大雨时通过浮力自动封住地铁站入口，有效防范了雨水的灌入。
