摘要
隧道排水工作是隧道施工修建过程的重要组成部分,尤其是反坡排水阶段。文章以成都至兰州的铁路CLZQ-6标段的杨家坪隧道4号横洞工区为例,结合地形、地质、地下涌水量、气象,参考类似施工方法案例,总结了该项目反坡排水及清污分流施工的基本原则及总体方案,计算正常涌水量,修建集水井,确定排水系统及清污分流施工方案,给出设备配备计算过程和计算依据,以保证设施选择的合理性。
Tunnel drainage is an important part of tunnel construction process,especially during the reverse slope drainage stage.Taking No.4 transverse tunnel working area of Yangjiaping Tunnel in CLZQ-6 bid section on Chengdu-Lanzhou Railway as an example,combined with topography,geology,underground water inflow,meteorology,and referring to similar construction method and cases,the basic principles and overall scheme of reverse slope drainage and clean sewage diversion construction of this project are summarized,normal water inflow is calculated,water collecting well is built,the drainage system and clean sewage diversion construction scheme are determined,and the equipment allocation calculation process and calculation basis are provided to ensure the rationality of facility selection.
