自动抽水装置在隧洞排水中的应用

Application of Automatic pumping devices in drainage tunnel

以宁波市白溪水库引水工程为例,介绍了自动抽水装置在降低破碎围岩、富水充分隧洞施工排水费用中的应用。结果表明:该装置能较好且又快速地排出隧道开挖集聚的地下水,有效地降低了排水费用和工程成本,该方法可为其他类似工程提供参考。

Taking water diversion project in Ningbo city Baixi Reservoir application of automatic pumping equipment in the lower broken rock, water-rich and as an example, the full drainage tunnel construction costs is presented. The results show that： the device can be better and draw groundwater from the tunnel excavation quickly, it is reducing the cost of drainage and engineering costs effectively, the method could provide reference for other similar projects.
