Abstract:

Taking No.3 inclined shaft of Xiangshan tunnel on LongyanXiamen railway as an example, the author focuses on the problems of the track transportation system of long steep inclined shafts. The layout of the parking on the bottom of the inclined shaft is optimized, which solves the interference among the construction procedures and improves the transportation efficiency by making a good match between the track transportation system in the inclined shaft and the trackless transportation system in main tunnel. Proper drainage system is installed, which solves the problems of antislope drainage in the inclined shaft and realize the target of safe and rapid construction.

Key words:  steep gradient, long distance, inclined shaft, parking on shaft bottom, optimization, antislope drainage
