Water-collecting well arrangement structure and underground powerhouse of hydropower station
The invention provides a water-collecting well arrangement structure and a hydropower station underground powerhouse, the hydropower station underground powerhouse comprises an underground powerhouse and a water-collecting well arrangement structure, the water-collecting well arrangement structure comprises a water-collecting well, a connecting gallery, a water pump, a water pump control room, a drainage vertical shaft and a drainage tunnel, the connecting gallery is used for communicating the water-collecting well with the underground powerhouse, and the water-collecting well is communicated with the underground powerhouse. A water pump is arranged in the water-collecting well, a water outlet pipe of the water pump is communicated to a drainage shaft, the upper end of the drainage shaft is communicated to a drainage hole, the water pump control chamber and the water-collecting well are arranged at an interval, and the bottom elevation of the water pump control chamber is not lower than the top elevation of the water-collecting well. The system can prevent the water pump and the control equipment from being damaged when the sudden water burst accident occurs in the underground powerhouse and the water collecting well is submerged by the burst water, and can ensure that the water pump can continuously pump and drain the burst water, so that the powerhouse flooding accident is avoided, or the powerhouse flooding time is prolonged, the escape time of hydropower station operation management personnel is prolonged, and the escape success possibility is improved.
本发明提供一种集水井布置结构及水电站地下厂房，所述水电站地下厂房包括地下厂房和集水井布置结构，所述集水井布置结构包括集水井、连接廊道、水泵、水泵控制室、排水竖井、排水洞，所述连接廊道用于连通集水井和地下厂房，所述集水井内设置水泵，所述水泵的出水管连通至排水竖井，所述排水竖井的上端连通至排水洞，所述水泵控制室与集水井之间间隔设置，且所述水泵控制室的底部高程不低于集水井的顶部高程。本发明可以防止地下厂房内发生突发涌水事故时，涌水淹没集水井时损坏水泵和控制设备，可以保证水泵能持续抽排涌水，从而避免水淹厂房事故，或延长水淹厂房的时间，以增加水电站运行管理人员逃生的时间，提高逃生成功的可能性。
