Description of Tunnel Lining Trolley
The tunnel steel formwork lining trolley is a combined steel structure portal frame to support the large steel structure formwork system and the electric motor traveling mechanism drives the trolley to travel. It is tunnel concrete forming equipment that uses hydraulic cylinders and screw jacks to adjust template positioning and demolding. It has the advantages of low cost, reliable structure, convenient operation, fast lining speed, and good tunnel forming surface which is widely used in the construction of highways, railways, hydropower, urban subways and other tunnels. The tunnel lining trolley can be designed according to the lining section drawing and technical requirements provided by the clients.
Components of Tunnel Lining Trolley
This trolley is composed of template assembly, top mold frame assembly, translation mechanism, gantry assembly, master-slave walking mechanism, screw jack, hydraulic system and electrical system, etc.
Working Principle of Tunnel Lining Trolley
The outer contour of the steel formwork tunnel lining trolley is consistent with the theoretical inner contour of the tunnel
lining. By blocking the two excavated silo surfaces of the formwork, a closed annular silo is formed with the excavated surface, and then concrete is poured to realize the tunnel lining construction. This tunnel lining trolley is powered by a motor, and a rail travel system; The formwork action mode is a hydraulic cylinder piston motion mode to complete erecting and keeping of template and adjust the center deviation of the template; After the template of tunnel lining trolley is erected, the template needs to be connected with frame body through the lead screw as a whole body to bear the construction load during the concrete pouring process.

Designing Points of Tunnel Lining Trolley
1. All arc flanges and reinforced arcs of the tunnel lining trolley formwork are made of 14mm steel plate and surface panel is made of 10mm steel plate to ensure that each concrete joint is smooth no misalignment.
2. The anti-dislocation lead screw is installed between the side form beam and the portal frame to ensure the stability of the formwork tunnel lining trolley during walking and prevent the formwork from being displaced back and forth during lining.
3. The grouting hole structure design adopts the screw cap operation method, so that the poured concrete does not leave any defects, and the operation is simple and convenient.
4. The trolley is driven by a motor, and the motor power is 2*5.5KW. The operation is simple, and the action is flexible and reliable.
5. The retractable mold is driven by hydraulic pressure, which can greatly reduce the labor intensity of construction and make the realization of various actions of the template simple and quick.
6. Bolt adjustment is used between the working window and the template, which is easy to open and close, and the gap is small.
7. All electrical components comply with household standards and are safe and reliable.
8. All hydraulic components and hydraulic pipelines conform to domestic standards, and there will be no leakage or blockage.
9. The lifting cylinder adopts mechanical self-locking, which is more reliable than hydraulic lock. It can prevent template
misalignment caused by tunnel lining trolley sinking and the lining quality is good.
10. The supporting jack adopts double-head screw, which has good supporting effect and large supporting force.
11. The diagonal bracing of the portal frame adopts channel steel beam butt buckle and the section is a box-shaped structure which has good force bearing effect.
