Underwater tunnel shield lowest point drainage pumping station, control system and drainage method
The invention belongs to the technical field of tunnel drainage, and particularly relates to an underwater tunnel shield lowest-point drainage pumping station, a control system and a drainage method. The drainage pumping station for the lowest point of the underwater tunnel shield comprises a water collecting pit, an integrated vacuum drainage unit, an integrated drainage unit and a monitoring structure. The control system comprises a vacuum pump control cabinet, a main pump control cabinet, a preparation pump control cabinet, a monitoring and water level monitoring control cabinet, a water quality online monitor and a remote transmission monitoring acquisition system. The water collecting pit is composed of the local water collecting pit and the main water collecting pit, waste water flows into the local water collecting pit firstly and then is discharged into the main water collecting pit from the local water collecting pit when reaching a certain water level, and waste water of the main water collecting pit is discharged when the main water collecting pit reaches a certain water level, so that tunnel waste water can be treated in time, a main pump can be prevented from being started and stopped frequently, and waste water treatment efficiency is improved. And the integrated vacuum drainage unit and the integrated drainage unit both adopt an integrated design, so that the equipment is small in size, small in occupied space and convenient to install and transport.
本发明属于隧道排水技术领域，尤其涉及一种水下隧道盾构最低点排水泵站、控制系统以及排水方法。水下隧道盾构最低点排水泵站包括集水坑、一体化真空排水机组、一体化排水机组以及监测结构。控制系统包括真空泵控制柜、主泵控制柜、预备泵控制柜、监控及水位监测控制柜、水质在线监测仪以及远传监控采集系统。本发明中集水坑由局部集水坑和主集水坑组成，废水先流入局部集水坑，到达一定水位时，再从局部集水坑排入主集水坑，当主集水坑到达一定水位时，再将主集水坑的废水排出，不仅可及时处理隧道废水，又可避免了主泵频繁启停，降低了能耗，一体化真空排水机组和一体化排水机组均采用一体化设计，设备体积小，占用空间少，安装及运输方便。
