Applications in High-Speed and Rail Tunnel Projects:
Tunnel Lining and Shotcrete Application:
The long robotic arm is perfect for applying wet shotcrete to the tunnel walls and ceiling, ensuring a smooth, uniform surface that is essential for tunnels that will handle high-speed rail traffic. The shotcrete adds structural support and prevents water ingress, which is critical for maintaining the tunnel over time.
Drilling for Rock Bolting:
In rock-based tunnels, rock bolting is essential to secure loose or fractured rock. The 12m robotic arm can precisely drill holes at various angles, ensuring that the bolts provide optimal support to the tunnel structure. Automated bolting systems attached to the arm can quickly insert bolts, reducing manual labor and enhancing safety.
Installation of Tunnel Support Systems:
In addition to rock bolting, the robotic arm can assist in the placement of tunnel support arches or lattice girders. These supports are often installed during the early stages of tunnel excavation to prevent collapses and maintain tunnel shape until the final lining is applied.
Spraying Waterproof Membranes and Sealants:
Water infiltration is a significant issue in tunnel construction, especially in areas with high groundwater levels. The robotic arm can be used to spray waterproofing membranes or sealants, which protect the tunnel lining from water damage, helping ensure the longevity of the structure.
Maintaining Tunnel Alignment and Track Installation:
In some cases, the robotic arm can assist in the precise placement of rail tracks or other equipment used in the tunnel. The extended reach allows for accurate positioning and reduces the need for manual labor in confined spaces.
A 12m long robotic arm is a critical asset in the construction of high-speed rail and rail tunnels, providing enhanced reach, precision, and safety. It improves the efficiency of tunnel lining, shotcreting, rock bolting, and other essential construction tasks, ensuring that tunnels are built to withstand the rigors of high-speed rail travel while reducing manual labor and increasing worker safety. The versatility of the robotic arm also makes it suitable for a wide range of tunnel construction activities, from initial excavation support to final finishing work.
