Description

Technical Field

[0001] The present invention relates to the technical field of tunnels, and more specifically to a method for multiple large-diameter water supply and drainage pipes to pass through a lining trolley in a tunnel. Background Art

[0002] In a water conveyance tunnel constructed by a general TBM, when the TBM drives along the slope and drains water against the slope, the reverse slope drainage pump station is arranged on one side. In this way, the drain pipes are arranged on one side for pumping drainage. When there is a large amount of water gushing in the tunnel, multiple large-diameter steel pipes are required for drainage. Usually, the drain pipes in the tunnel are arranged on the tunnel wall, and the water supply pipe of the TBM is also on this side. When the lining trolley passes through, only the section of the steel pipe that interferes with the lining trolley can be temporarily removed, and a hose or other form is used for transitional connection. After the lining concrete is completed and the lining trolley leaves, it is restored, which is very troublesome. Summary of the Invention
