Abstract:Aiming at the problems of difficult operation and low excavation accuracy of open TBM in the process of small curve cornering, the structural mechanism, and motion characteristics of the traditional Horizontal main beam type TBM and the new 8-SPS V-type TBM mainframe were compared and studied. Based on the drainage channel project of a pumped storage power station, the factors affecting the minimum turning radius of TBM were analyzed by establishing two TBM main engine turning direction models. Secondly, the d… Show more
