公路隧道纵向排水盲沟施工技术研究

Research on Construction Technology of Longitudinal Drainage Blind Ditch of Highway Tunnel

纵向排水盲沟是隧道防排水系统中重要的一环,在施工环节保证排水盲沟的施工质量是确保排水系统通畅的关键性工作。本文结合工程实践,针对纵向排水施工过程中的存在的问题,提出施工改进方案,提高了排水盲沟的施工质量。

The vertical drainage blind ditch is an important part of the tunnel anti-drainage system.The construction quality of the drainage blind ditch in the construction link is the key to ensure the smooth drainage system.Based on engineering practice,this paper proposes a construction improvement plan for the problems existing in the longitudinal drainage construction process,which improves the construction quality of the drainage blind ditch.
