Description

Technical Field

[0001] The utility model relates to the technical field of tunnel trolleys, in particular to a tunnel trolley template structure. Background Art

[0002] The tunnel lining trolley is a special equipment that must be used in the secondary lining of the tunnel construction process. It is used for the concrete lining construction of the inner wall of the tunnel. Secondary masonry is a very important construction process in the tunnel construction process. It is a process of building a permanent support structure with steel bars and concrete materials around the tunnel body to prevent the surrounding rock from deformation or collapse.

[0003] During the use of the tunnel trolley formwork, the constructed tunnel trolley needs to be used inside the tunnel, and the tunnel trolley formwork needs to support the concrete. Therefore, a support device needs to be installed at the lower end of the trolley to ensure the overall support force of the trolley. Common support devices use hydraulic rods that extend horizontally and vertically to the ground to increase the overall support force of the equipment. Since the formwork needs to be filled with concrete all around, the trolley will be subjected to forces in different directions. When the trolley is under lateral pressure, the trolley will tip over as a whole. For this reason, we proposed a tunnel trolley formwork structure. Utility Model Content
