Tunnel Liners are prefabricated corrugated steel structures used in the construction of tunnels. They are assembled inside the tunnel as it is excavated, providing immediate structural support. This technique is particularly useful in urban areas or beneath existing structures, where minimal surface disruption is essential.

How Does Tunnel Liner Installation Work?

The installation involves assembling sections of corrugated steel sheets bolted together to form a continuous lining within the tunnel. This method can be executed manually or with mechanical assistance, allowing for flexibility in various ground conditions. Tunnel Liners can adapt to different shapes and sizes, which makes them ideal for various applications such as stormwater drains, pedestrian tunnels, and service conduits

What Are the Benefits of Using Tunnel Liners?

1. Cost-Effective: They reduce the need for extensive excavation and surface disruption, which lowers overall construction costs.

2. Speed: The prefabricated nature allows for rapid assembly and installation.

3. Versatility: Suitable for different types of projects including drainage, ventilation tunnels, and utility passages.

4. Safety: Provides immediate support to the excavated tunnel, enhancing safety during construction.
