Common types of tunnel lining templates

Common types of lining templates are: integral mobile formwork trolley, traversing (split moving) formwork trolley, and assembled arching formwork.

1, the overall mobile template trolley

The overall mobile formwork trolley is mainly suitable for tunnel lining construction with full-section one-time excavation or large-section excavation. However, its size is relatively fixed, and the adjustable range is small, which affects its applicability.

2, through (split mobile) template trolley

It not only improves the utilization rate of the running mechanism, but also can be implemented at the same time.

3, assembled arch template

The assembled arch template is suitable for both straightforward and reverse works, but assembling and demolishing are time-consuming and labor-intensive.
