反坡富水岩溶隧道抽排水系统的设置和应用

反坡富水岩溶隧道施工的主要难题是反坡抽排水,而快速有效地排除反坡施工地段的积水,对隧道的施工组织和现场管理影响重大。通过对宜万铁路齐岳山隧道进口段抽排水系统设置的论述,进一步说明快速有效的排水系统和良好的排水管理可以为富水岩溶反坡隧道施工提供相对安全的施工环境,进而为溶腔探测试验提供可能。

Arrangement and Application of the Tunnel Drainage System in the Reverse-Slope Stratum with Abundant Water

Drainage in a reverse slope is the primary problem in the construction of a tunnel in a reverse-slope stratum with abundant water.How to drain water logging quickly and effectively from the constructing zone in a reverse slope is of great importance to the construction organization and the on-the-spot management.This article expatiates the arrangement of the drainage at Qiyueshan Tunnel entrance,illuminates that with proper management of a quick and effective drainage system,a relatively safe construction environment in a tunnel through reverse-slope stratum with abundant water and the conditions for Karst cave detecting test can be achieved.
