The common types of lining formwork are: integral mobile formwork trolley, traversing (separate moving) formwork trolley, assembled arch formwork.

1. Overall mobile formwork trolley

The integral mobile formwork trolley is mainly applied to the tunnel lining construction of full section excavation or large section excavation. However, its size is fixed and its adjustable range is small, which affects its applicability.

2. Through type (separate moving) formwork trolley

Not only improve the utilization rate of the running mechanism, but also can be implemented at the same time.

3. Assembly type arch template

The assembled arch formwork is suitable for both forward and reverse working, but the assembling and disassembling are time-consuming and costly.
