Abstract

This paper firstly analyzes the installed capacity of pumped storage power station, power generation head, Angle of inclined shaft, design requirements of regulation guarantee, head loss, etc. The preliminary design of inclined shaft is studied. Then, the comparison of 3 schemes of diversion inclined shaft TBM construction is carried out. Comprehensive consideration is given to the factors such as structural layout, water head loss, guarantee safety in complex adjustment state, construction difficulty and safety risk, etc. Comprehensive analysis shows that it is more feasible to adjust the upper inclined shaft, middle horizontal hole and lower inclined shaft into a primary inclined shaft, and adopt the TBM with diameter Φ7.2m section to carry out diversion inclined shaft construction. The design scheme can provide technical reference for the design and construction of similar projects in China.
