Abstract:As a clean and efficient way of electric energy storage,pumped storage power station has a broad market and a good application prospect.The diversion inclined shaft of pumped storage power station has the characteristics of large slope and complex route.In the construction process,TBM is often used for reverse construction,which is also called reverse inclined shaft construction.Aiming at the problems such as difficult attitude control and slipping during the excavation of inclined shaft with large slope ratio,multiple self-locking anti-slipping technology is developed,so that multiple sets of bracing devices are working during TBM excavation and step change,which meets the strict safety construction requirements.Using this technology,the stability of TBM in the process of anti-inclined shaft excavation can be improved,and the excavation and step change can be carried out at the same time,with high attitude control accuracy and high construction efficiency,and the tunneling ability of TBM under the condition of large slope can be improved.
