Description

Technical Field

[0001] This utility model belongs to the field of tunnel muck removal technology, specifically a tunnel muck removal device for highway tunnels. Background Technology

[0002] In highway tunnel construction, the accumulation of slag and rock inside the tunnel can affect the working space and traffic safety of construction workers. Timely removal of slag and rock can eliminate these safety hazards and reduce safety risks during construction. Moreover, in tunnel construction with poor geological conditions, timely removal of slag and rock can help maintain the stability of the surrounding rock and prevent collapse accidents caused by uneven stress on the surrounding rock due to excessive accumulation of slag and rock.

[0004] After prolonged use, it was found that traditional tunnel muck removal devices consume excessive energy for crushed stone, which can easily cause environmental pollution. Even with energy-saving and environmentally friendly methods, large pieces of crushed stone in tunnel muck removal are difficult to handle, affecting the tunnel muck removal process.
