浅析隧道超前排水技术

Analysis on Advanced Drainage Technology of Tunnel

随着我国铁路建设工作的不断深入,越来越多的铁路隧道开始投入建设,隧道排水问题关系到工程质量与安全,是一项重要施工工艺。新建玉铁铁路杉坡岭隧道为克服富水段带水作业难题,采用超前排水施工技术。该技术结合超前地质预报、打孔泄压、反坡排水及设备配置等内容,能够提高带水作业效率和增加施工企业效益,也能够避免富水地层隧道开挖涌水与承压水对主体结构的危害。

With the continuous deepening of China’s railway construction, more and more railway tunnels are being constructed. The problem of tunnel drainage is an important construction process that relates to project quality and safety. In order to overcome the difficulty of carrying water in the water-rich section, the newly built Shanpoling Tunnel of Yutie Railway adopts advanced drainage construction technology. This technology combines advanced geological forecasting, pressure relief for drilling, reverse slope drainage, and equipment configuration, which can improve the efficiency of water carrying operations and improve the efficiency of construction enterprises. It can also avoid the harm of the ingress of water and pressured water to the main structure of the water-rich stratum tunnel.
