Product Description
Tunnel lining trolley, also known as a lining formwork carriage or tunnel lining formwork carriage, is a large, fully automated, monolithic steel formwork system used in the concrete pouring of tunnels, culverts, and water diversion tunnels. It utilizes a hydraulic system to lift, move, and position the entire structure, enabling the concrete for the arch and walls to be poured and formed in a single operation. It is a core piece of specialized equipment in tunnel construction.
Main Components
The machine consists of a formwork assembly, a gantry assembly, a hydraulic system, a travel mechanism, support screws, and an electrical control system. It features high overall rigidity and precise positioning.
Features and Advantages
1. Monolithic casting with an aesthetically pleasing finish: The concrete surface is flat and smooth, requiring no secondary finishing.
2. High degree of automation: Hydraulically driven, simple to operate, and precise positioning.
3. High construction efficiency: Reusable, significantly shortening construction time
4. High safety: Sturdy structure with high load-bearing capacity, suitable for long periods of continuous operation
5. Versatile: Customizable to fit tunnel cross-sectional dimensions, suitable for a wide range of working conditions
Applications
Widely used in the construction of concrete linings with curved or circular cross-sections in highway tunnels, railway tunnels, hydraulic culverts, urban subways, utility tunnels, and water diversion projects.
