AI Technical Summary
In existing green and environmentally friendly drainage structures for tunnels, the filter layer tends to accumulate solid particles after long-term use, leading to decreased work efficiency and requiring cumbersome disassembly and cleaning, which is also labor-intensive.
A green and environmentally friendly drainage structure for tunnels was designed, including a traveling trolley, a cleaning mechanism, a pneumatic gripper, a drive assembly, and an adjustment mechanism. The filter pipe is easily disassembled and cleaned by a cleaning device, enabling rapid disassembly and cleaning of the filter pipe.
This improves the efficiency of tunnel drainage system inspection and maintenance, saves labor costs, and ensures the system's long-term normal operation.
