Tunnel lining cart is a special equipment that must be used in the secondary lining of tunnel construction process, which 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 cart, fully hydraulic automatic walking lining cart and net frame lining cart. This equipment has a streamlined structure, convenient operation, standardized and modular design in all aspects, which is easy to manufacture, shipment, on-site disassembly and management.
Tunnel lining cart is widely used in industrial production, medical scene water conservancy, underground engineering, mining and tunnel construction and other fields. Among them, the advantages of tunnel lining cart in tunnel construction are mainly reflected in the following aspects:
1. Construction efficiency: tunnel lining cart can be quickly moved to any position in the tunnel, so that the lining construction can be carried out continuously, reducing the movement time of construction personnel and equipment, thus significantly improving the construction efficiency.
2. Construction cost control: By using tunnel lining carts, the demand for human resources can be reduced, and the mechanization rate of tunnel second lining construction can be improved, thus reducing the labor cost and improving the construction progress.
3. Construction quality assurance: Tunnel lining cart can ensure the shape and size accuracy of concrete lining, provide a stable operation platform for construction personnel, and help to improve the quality of tunnel lining construction.
4. Strong adaptability: Tunnel lining cart includes side roof arch cart, straight wall variable cross-section roof arch cart, full-circle needle beam cart and full-circle walk-through cart. The tunnel lining trolleys are of different types. Different types of carts can meet the needs of different situations with high flexibility.
5. Enhanced safety: Tunnel lining carts provide a safe working platform for construction personnel, reduce the risk of working at height and enhance the safety of construction.
6. Widely used: Tunnel lining dollies are widely used in the construction of highway, railroad, water conservancy and hydropower and municipal, anti-military and other projects, applicable to various types of tunnel construction.
With the advantages of high efficiency, safety and reliability, tunnel lining carts ensure the long-term stability and safety of tunnels through efficient concrete lining operations. With the further development of modern science and technology, the design of modern lining cart pays more attention to automation and intelligence to adapt to various complex geological conditions and construction requirements. We can see that the future development prospect of tunnel lining cart is very optimistic, on the one hand, thanks to the continuous progress of technology, on the other hand, the growth of market demand for tunnel lining cart provides a broad application space. Therefore, it is believed that tunnel lining dollies will continue to develop and play a higher level of role.
