In A Railway Tunnel In Yangjiang, A Drum Cutter Is Trimming The Wall

As the core product of Yichen Company, Drum Cutter has participated in many tunnel construction projects since the first equipment came out. It is simple to operate, easy to control, and can be used for fine trimming of tunnel walls, tops, corners, contours, etc.

In Yangjiang City, Guangdong, a railway tunnel is under construction. At the construction site, we found the Yichen Drum Cutter. It is installed on a Sany 215C excavator and is repairing the wall inside the tunnel. The walls inside the tunnels need to be flattened before further treatment. This is a "fine job", once over-excavation or under-excavation will result in a waste of manpower and material resources, increase the project cost and prolong the construction period. The addition of Yichen's Drum Cutter makes this work simple and efficient. The excavator driver can easily operate the Drum Cutter, and use the cutter teeth mill down the irregular parts on the wall to obtain a relatively flat surface. wall, to provide protection for subsequent construction.

By the end of last year, the tunnel had been successfully penetrated. The tunnel is located in Yangjiang City, Guangdong Province. It is a V-level surrounding rock. The rock mass is broken, and the surrounding rock has poor integrity and stability. It is mainly composed of silty clay and fully weakly weathered migmatite. The geological conditions are complex and the design standards are high. The construction is difficult and the safety risk is high. In such a construction environment, the features of low noise and low vibration of the Drum Cutter perfectly adapt to the working conditions and give full play to its advantages.
