Underpass tunnel drainage structure and integrated prefabricated drainage pumping station
The invention provides an underpass tunnel drainage structure which is high in drainage efficiency, low in energy consumption and not prone to water accumulation in an underpass tunnel and an integrated prefabricated drainage pumping station, and relates to the technical field of drainage engineering. The underpass tunnel drainage structure comprises a drainage pump station, and at least two water collecting tanks arranged at intervals are sequentially arranged from a longitudinal slope of an underpass tunnel to the slope bottom from top to bottom; the drainage pumping station is arranged on one side of a longitudinal slope of the underpass tunnel and comprises a well body and a drainage pipe arranged in an inner cavity of the well body to drain water outwards, at least two water pumping devices are sequentially and fixedly arranged in the inner cavity of the well body from bottom to top at intervals, and the water outlet ends of the water pumping devices are connected to the drainage pipe in parallel. A one-way valve capable of enabling water flow to flow into the drainage pipe from the water pumping device in a one-way mode is arranged between the water outlet end of each water pumping device and the drainage pipe. The drainage efficiency of the underpass tunnel is guaranteed, and energy conservation and emission reduction are achieved.
本发明是提供一种排水效率高，能耗低，下穿隧道不容易积水的下穿隧道排水结构及一体化预制排水泵站，涉及排水工程技术领域。下穿隧道排水结构，包括排水泵站，所述下穿隧道的纵坡上至坡底而上依次设有至少两个间隔设置的集水槽；所述排水泵站设置在下穿隧道的纵坡一侧，包括井体和设置在井体的内腔内以向外排水的排水管，所述井体的内腔内至下而上依次间隔设置固定有至少两个抽水装置，所述抽水装置的出水口端并联在所述排水管上，每个所述抽水装置的出水口端与所述排水管之间均设有可使水流从抽水装置单向流入排水管的单向阀。本发明保证了下穿隧道的排水效率，节能减排。
