丁家营隧道防排水专项施工方案探讨

Discussion on Special Construction Scheme for Waterproof and Drainage of Dingjiaying Tunnel

丁家营隧道是新建铁路武汉至十堰铁路孝感至十堰段HSSG-3标的一个重要工程,地下水对施工及运营影响较大,文章从洞口及地表防排水、洞口明挖段防排水、洞内防排水、结构防排水、辅助坑道防排水等方面,对排水专项方案进行了探讨。研究成果为隧道安全施工提供了技术支持,也可为类似工程提供参考。

Dingjiaying Tunnel is an important project of HSSG-3 in Xiaogan-Shiyan section of Wuhan-Shiyan Railway. Groundwater has a great influence on construction and operation.This paper discussed the special drainage schemes from the aspects of tunnel entrance and surface waterproof and drainage,open-cut section waterproof and drainage of tunnel entrance, waterproof and drainage in tunnel,structural waterproof and drainage,auxiliary tunnel waterproof and drainage.The research results provide technical support for tunnel safety construction,and also provide reference for similar projects.
