Underground structure space channel entrance flood prevention device and construction method thereof
The invention discloses an underground structure space channel entrance flood prevention device. A channel entrance comprises a concrete ramp plate and entrance ramp side walls arranged on the two sides of the concrete ramp plate. A long-strip-shaped transverse water retaining dam lifting opening is formed in the concrete ramp plate, a lifting water retaining dam body is arranged in the water retaining dam lifting opening, and the lifting water retaining dam body is jacked and descended through a jacking mechanism arranged below the notch. The invention further discloses a construction method of the flood prevention device. By the adoption of the technical scheme, when flood disasters occur, the lifting water retaining dam can rise rapidly, water flow is prevented from flowing backwards, and underground space is prevented from being flooded; the control performance of the device is good, reliable sealing can be achieved, and leakage is prevented; and the structure is good in concealment performance and basically has no influence on normal operation and appearance at ordinary times.
本发明公开了一种地下结构空间通道入口防汛装置，通道入口包括混凝土坡道板以及设置在混凝土坡道板两侧的入口坡道侧墙；混凝土坡道板上设置一个长条形横向的挡水坝升降口，在该挡水坝升降口中设置升降挡水坝体，该升降挡水坝体由设置在缺口下方的顶升机构进行顶升和降落。本发明还公开了该防汛装置的施工方法。采用上述技术方案，在发生洪涝灾害时，升降挡水坝能迅速升起，防止水流倒灌，避免地下空间被淹；装置的操控性能好，能实现可靠密封，防止渗漏；结构的隐蔽性能好，对平时的正常运行及外观基本没有影响。
