摘要
Abstract
Due to the narrow cross-section and long transportation distance of small diameter TBM tunnels with a diameter of 3-4 meters,the excavated soil and materials are mostly transported by single track tracks and horizontally transported by grouped trains.As the transportation distance inside the tunnel gradually increases,trains cannot be staggered inside the tunnel,and trains can only be staggered at the entrance switch.Only one train can run in the tunnel at the same time,which will greatly limit the efficiency of material transportation in the tunnel and affect the normal excavation of TBM.Based on the successful application of mobile switches in the self flowing drainage tunnel of Nanning Pumped Storage Power Station,this paper summarizes and discusses the construction technology of mobile switches in long-distance small section TBM tunnels.关键词
