| Abstract: | With a total length of 5212m, circular profile and maximum excavation diameter of 4.6m, the diversion tunnel of No.2 Kunjiang Hydropower Station consists of tunnel, surge shaft and vertical shaft. Air leg drill was used for tunnel excavation. Deposit was transported with ballast harrow and dump truck. Advanced concreting technique was adopted such as pump grouting, large scale steel-form trolley and slip formwork, which guarantees the construction quality and renders rapid concreting. |
