Advantages of Roller Cutter System for Trench Cutter in Hard Rock Cutting

1. It can significantly reduce the construction cost by trench cutters in hard rock formations and shorten the project construction period;

2. Guide holes are not needed, which simplifies the construction equipment.

3. The roller cutter wheel can work continuously for a long time(can achieve 100 hours of continuous operation), reducing the number of times the cutter frame is lifted up, effectively extending the construction time and reducing the number of workers;

4. The cutter frame works stably, the gearbox has little impact, and the maintenance time and cost are reduced;

5. The disturbance to the ground is small and the construction can be carried out near buildings;

6. Improve the deviation correction ability of trench cutter in hard rock formations;

7. The vertical accuracy of the diaphragm wall can be controlled within 1‰;

8. Fuel saving and environmentally friendly
