Drum cutters are very effective in demolishing buildings, cutting foundations, concrete slabs and thick concrete walls with less reinforcement. It can fulfill the dual functions of hydraulic hammer and hydraulic tongs, because it can cut the steel bars in the building at the same time. The abrasive material has a small particle size and can be directly used as backfill material.

Replication, excavation, quarrying, demolition, dredging, restoration and underwater operations of rock-cement walls. They are very effective when traditional mining systems are so weak that crushing systems are almost ineffective. Their quiet operation allows them to work near sensitive areas (residential areas, hospitals, schools, bridges and infrastructure). Highly recommended for high precision, minimal impact and finishing operations.

Because all equipment should be stored on the steps, the distance between the upper and lower steps is 800-1100 meters. Step-by-step excavation support: After excavation, steel mesh steel grid shotcrete is used to support the tunnel.

In soft rock, the depth of each excavation depends on the rock formation in the tunnel and the pre-design of the tunnel design unit, generally 50~80cm.
