Protection Construction and Monitoring Technology of Power Pipe Trench in Subway Station
The construction problems in the key areas between the power pipe trench and the station end shaft are successfully solved,and the engineering monitoring methods and emergency plans are discussed through the application of micro-isolated piles and isolated sand piles.In the construction process,the isolation and reinforcement measures were implemented in strict accordance with the specifications to ensure the smooth progress of the project.Surface subsidence,displacement change and power pipe trench vibration were monitored comprehensively.The influence of construction on the surrounding environment and power pipe trench was effectively controlled by tracking the construction process in real time.The comprehensive application of the proposed construction technology and monitoring scheme provides strong support for the safe and smooth implementation of the project.
