In a tunnel project with sandstone and siltstone layers, Yichen drum cutters enabled safe, precise excavation without blasting. For hard rock sections, rock saws pre-cut the surface into grids, followed by breakers for efficient removal. Excavated rock was then processed on-site using Yichen crusher and screening buckets, turning it into reusable aggregate for landfill or backfill. This integrated solution improved safety, reduced pollution, and promoted material reuse during tunneling.
Tunnel construction has always been the peak of construction projects, and it is difficult to build. Before the 1960s, the combination of drilling and blasting was used in the construction of tunnels. The disadvantages of this method are very obvious...
