摘要
本文介绍了隧道穿越市政道路的施工方法,施工中采用了超前小导管、大管棚、深孔注浆等超前加固措施并采取一定的监测手段,使道路路面和地下管道沉降变形控制在要求的范围内,确保了市政道路的交通运行安全,对类似工程施工有一定的参考价值.
This article describes the construction methods of tunnels crossing municipal roads.In the construction,advanced reinforcement measures such as advanced small pipe.1arge pipe shed and deep hole grouting afe adopted,and certain monitoring measures are used to control the settlement deformation of road pavement and underground pipe within the required range.It could ensure the traffic safety of municipal road,and provide a certain reference value for similar projects.
