摘要
南水北调穿黄隧洞工程采用世界先进的泥水加压平衡式盾构施工,掘进至隧洞桩号7+762.80处盾构机刀具磨损严重,需要及时更换。为保证换刀工作能在干旱的基坑中顺利进行,必须进行降排水。本文介绍了降排水方案在该工程中的应用,以期为类似工程提供借鉴经验。
World advanced slurry pressure balanced shield construction is adopted in Yellow River penetration tunnel work of south-to-north water diversion project.Shield machine tool is seriously worn when it is drilled to tunnel pile number 7 ＋762.80,which should be timely replaced.Dewatering and drainage must be implemented in order to ensure smooth tool changing work in drought foundation pit.In the paper,application of dewatering and drainage plan in the project is introduced,and it is expected that it can provide reference and experience for similar projects.
