What are the advantages of tunnel lining trolley in tunnel construction?

The tunnel lining trolley is a special equipment that must be used in the secondary lining of the tunnel construction process. It is used for the concrete lining construction of the inner wall of the tunnel. This equipment is an indispensable non-standard product for secondary lining, mainly including simple lining trolleys, fully hydraulic automatic walking lining trolleys and grid lining trolleys. This equipment has a simple structure and is easy to operate. All links are standardized and modularized, which is convenient for manufacturing, shipping, on-site disassembly and management.

‌Tunnel lining trolleys are widely used in industrial production, medical scene water conservancy, underground engineering, mining and tunnel construction. Among them, the application advantages of tunnel lining trolleys in tunnel construction are mainly reflected in the following aspects:

1. Improved construction efficiency: The tunnel lining trolley can be quickly moved to any position in the tunnel, so that the lining construction can be carried out continuously, reducing the moving time of construction personnel and equipment, thereby significantly improving construction efficiency.

2. Construction cost control: By using tunnel lining trolleys, the demand for human resources can be reduced, and the mechanization rate of tunnel secondary lining construction can be increased, thereby reducing labor costs and improving construction progress.

3. Construction quality assurance: The tunnel lining trolley can ensure the shape and size accuracy of the concrete lining, provide a stable operating platform for construction personnel, and help improve the quality of tunnel lining construction.

4. Strong adaptability: The tunnel lining trolley includes side arch trolley, straight wall variable section arch trolley, full circle needle beam trolley and full circle walking trolley. Different types of trolleys can meet the needs of different situations and are very flexible.

5. Enhanced safety: The tunnel lining trolley provides a safe working platform for construction personnel, reduces the risk of high-altitude operations, and enhances the safety of construction.

6. Wide application: The tunnel lining trolley is widely used in the construction of highways, railways, water conservancy and hydropower, municipal engineering, defense and military engineering, and is suitable for various types of tunnel construction. ‌

The tunnel lining trolley, with its advantages of high efficiency, safety and reliability, ensures the long-term stability and safety of the tunnel through efficient concrete lining operations. With the further development of modern science and technology, the design of modern lining trolleys pays more attention to automation and intelligence to adapt to various complex geological conditions and construction requirements. 

We can see that the future development prospects of tunnel lining trolleys are very optimistic. On the one hand, it benefits from the continuous advancement of technology. On the other hand, the growth of market demand also provides a broad application space for tunnel lining trolleys. Therefore, it is believed that tunnel lining trolleys will continue to move forward and play a higher level of role.
