Lining cart, also known as tunnel lining cart, is a kind of mobile equipment specialized in secondary lining construction of tunnels. Its main role is to carry out inner lining of concrete and other materials for tunnels that have been initially supported during tunnel construction, in order to reinforce the support, optimize the route’s anti-drainage system, beautify the appearance, and provide conditions for the installation of facilities such as communication, lighting, and monitoring. The purpose of lining is to enhance the structural stability of the tunnel, optimize the anti-drainage system, and provide support for the subsequent installation of facilities. Lining carts can improve construction efficiency, reduce labor intensity and improve lining quality. As an important engineering machinery, tunnel lining cart plays a key role, so let’s look at it can be applied in which scenes:
Application Scenarios for Tunnel Lining Trolleys
1、Transportation tunnel construction
Tunnel lining dollies play a crucial role in highway and railroad tunnel construction. After the tunnel is excavated, the inner wall of the tunnel needs to be lined to ensure its safety and stability. Like some highway construction, the complexity of the terrain and the diversity of the tunnel cross-section makes the operation more difficult, tunnel lining cart can improve the construction efficiency, to protect the quality and appearance of tunnel lining; in the railroad tunnel construction, the surface flatness of the tunnel requires a very high degree of tunnel lining carts can meet its needs. In the railway tunnel construction, the tunnel surface flatness requirement is very high, tunnel lining trolley can meet its needs
2、Water conservancy and hydropower engineering
With the construction of hydropower station, the construction of tunnel lining cart has become an important part. In the water conservancy and hydropower project, the tunnel structure needs to withstand significant water pressure and geological stress, therefore, the performance of the lining structure puts forward more stringent requirements. The cart used in tunnel lining construction can ensure the accuracy of the lining operation, which is essential for maintaining the structural stability of the tunnel and guaranteeing construction safety. In addition, the trolley adopts efficient mechanized operation mode, which not only significantly improves the construction efficiency, but also effectively reduces the overall cost of the project.
