Common types of tunnel lining formwork
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.
Key points of making tunnel lining formwork trolley
The second lining construction (including the widening section) should adopt the whole hydraulic automatic walking lining trolley, the lining trolley should have accurate structure size, all kinds of telescopic components, hydraulic system, electrical control system running well, reasonable setting of supporting mechanisms; It should meet the requirements of automatic walking and have a locking device to ensure accurate positioning.
