Description

Technical Field

[0001] This utility model relates to a construction trolley for the secondary lining of a full-circle tunnel, and in particular to a construction trolley for the secondary lining of an S-shaped curved full-circle tunnel. Background Technology

[0002] Currently, the construction of full-circle S-shaped tunnels involves using small formwork and a full-span support frame to install the formwork for lining. Lining requires formwork units divided into upper curved sections, inclined straight sections, and lower curved sections. The mechanization level of formwork installation is low, making construction difficult. Existing full-circle S-shaped tunnel construction methods lack specialized equipment and rely on full-span support frames, resulting in complex and challenging construction facilities. Furthermore, the assembly of small formwork for S-shaped tunnels leads to numerous joints in some areas, easily causing misalignment, resulting in long construction periods and difficulties in ensuring construction safety and quality. In view of these reasons, a construction trolley for the secondary lining of S-shaped curved full-circle tunnels is proposed. Utility Model Content
