Construction Technology for Temporary Support Demolition of Double Side Wall Guide Pit Method in Large Section Shallow Buried and Underexcavated Tunnel
With the continuous development and progress of urban underground engineering,tunnels for various purposes are constantly being built,and the level of tunnel construction technology is also constantly improving and developing.This also makes the construction of urban subways more complex.Compared with the traditional construction method mainly using open cut method,the current subway tunnel construction generally combines various methods such as open cut,cover cut,shallow buried and underground excavation,greatly promoting the rapid development of urban underground rail transit engineering.Practice has proven that choosing a reasonable construction method is the key to the success or failure of urban underground rail transit projects.The shallow buried and underground tunnel behind the airport station of Xi'an Metro Line 14 is constructed using the"double side wall guide method".This article briefly introduces the construction technology of temporary support removal using the double side wall guide method,and summarizes the experience and guides the construction based on the monitoring data of the first 18m section.
