Research on Key Technologies for Quality Control of Large-diameter Track TBM Construction
Tunnel Boring Machine(TBM)construction is a widely used technology in modern rail transit tunnel engineering.In order to ensure the safety,reliability and economy of tunnel construction,it is necessary to carry out comprehensive quality control of TBM construction.Based on the construction of Lixue Road Station-Jinshan Temple Station section of the second phase project of Chongqing Metro Line 15,this paper mainly studies the TBM tunneling,segment assembly,filling grouting behind the wall,etc.,and puts forward control technologies such as pneumatic tunneling mode,segment assembly,synchronous grouting,secondary grouting.After practical application,the problems of segment dislocation and floating during the trial tunneling have been effectively solved to ensure the construction quality and safety.
