Abstract:

The inclined shaft of Daxiangling tunnel has long distance, steep gradient and complex geological conditions. The equipment matching, concrete delivery method and lining construction technology for the inclined shaft with steep gradient and long curve are presented in this paper. After comparison of 3 options, the traction system that consists of 5t type winch and 3×4 pulley block is selected for the lining formworks trolley in this project, which ensures the proper positioning and moving of the lining formworks trolley and guarantees the construction schedule. This technology has good practicability and has achieved good economic and social benefit in the construction.
