Freezing Synchronous Construction Technology of Shield and Communication Channel in Subway Section
In the construction of subway shield tunnel,the contact passage is an important structural part,and its construction safety and stability directly affect the operation safety of the whole tunnel.The freezing synchronous construction technology of shield and contact channel in subway section is a safe,effective and economical con-struction method,which is especially suitable for subway tunnel construction under complex geological conditions.By using the freezing synchronous construction technology,high strength and good sealing frozen soil curtain can be formed through formation freezing to prevent geological disasters such as piping and sand flow.In this paper,through the implementation of freezing synchronous construction technology,the formation is effectively strength-ened and the groundwater level is effectively controlled,and the phenomenon of piping and sand flow in the con-struction process is prevented.
