摘要
祁连山隧道2号斜井在施工过程中突发涌水并在很短的时间内淹井,严重影响了施工工期,并造成了安全、质量隐患。根据斜井实际抽排水过程,总结了隧道富水段反坡抽排水技术。
During the construction of No. 2 inclined shaft of Qilianshan Tunnel, sudden gushing water occurred and made the shaft flooded in a very short period of time. It seriously affected the construction period, and resulted in risks of safety and quality. Based on the drainage process of the shaft, this article summarizes the reverse-slope drainage pumping technology in water rich section of tunnels.
