AI Technical Summary

Technical Problem

Existing waterproofing and drainage structures in highway tunnel construction are prone to blockage of drainage pipes due to the accumulation of silt and other foreign objects, which reduces drainage efficiency and affects tunnel safety.

Method used

A crushing component was designed, including a feed hopper, a moving sleeve, grinding blocks, and a rotating drum. Through the processes of introducing waste, rotating and displacing the moving sleeve, and rotating and crushing the waste, the waste is crushed, reducing its volume and improving the practicality of the drainage structure.

Benefits of technology

The design of the crushing components significantly improves the overall practicality of the drainage structure in highway tunnel construction, ensuring smooth drainage, preventing water accumulation in the tunnel, and enhancing tunnel safety performance.
