Abstract
In order to solve the problems of difficult control and easy deformation in the construction of inclined shaft leadingin tunnel in Kras Guiyang metro station, the inclined shaft leading-in tunnel in Beijing Road station of Metro Line 3 is taken as an example. This paper puts forward the key construction technology of the top-lifting conversion of the inclined shaft entering the main tunnel, condenses the construction scheme, the construction flow and the construction key technology, and realizes the safety, the order, the fast and the high quality in the whole top-lifting conversion process. It not only ensures the safety construction of this project, but also provides reference for other similar projects.
