1. What is a tunnel liner plate?
2. How is a tunnel liner plate used in tunnel construction?
### Answer:
A tunnel liner plate is a type of pre-fabricated steel plate used in tunnel construction to line the interior of a tunnel and provide structural support. .
### How is a tunnel liner plate used in tunnel construction?
1. Tunnel liner plates are installed by inserting them one by one into the tunnel excavation, forming a continuous lining along the tunnel walls.
2. These plates are often interlocked or bolted together to create a stable and secure structure that can withstand the pressure of the surrounding earth and rocks.
3. The primary purpose of a tunnel liner plate is to prevent the collapse of the tunnel walls during construction and to provide long-term protection and support for the tunnel once it is in use.
4. Tunnel liner plates are commonly used in a variety of tunnel construction projects, including road tunnels, railway tunnels, and utility tunnels.
5. The steel plates used in tunnel liner plates are typically designed to be durable, corrosion-resistant, and able to withstand the specific conditions of the tunnel environment.
6. By using tunnel liner plates, construction time can be minimized, and the overall cost of the project can be reduced. Additionally, tunnel liner plates provide a smooth and consistent interior surface, which can improve the safety and efficiency of the tunnel for both construction workers and users.
