A Double Shield TBM is a tunnel boring machine that uses two shield walls to protect the tunnel excavation face during the excavation process. This type of TBM is commonly used for tunneling in urban areas where the risk of ground subsidence is high. Double Shield TBM 17"disc cutters for different soil are a type of cutting tool that are used to excavate the tunnel face during the drilling process in Double Shield TBMs.
Double Shield TBM 17"disc cutters for different soil are attached to the front of the TBM and are rotated by the main drive motors of the machine. The disc cutters are used to excavate the ground at the tunnel face, and the excavated material is transported out of the tunnel through a conveyor belt system or by a slurry system.
Double Shield TBM 17"disc cutters for different soil are designed to have a long service life and are made of high-quality materials such as tungsten carbide or diamond. They are also designed to be easily replaced when they wear out, which is an important factor in reducing downtime during the tunneling process.
In conclusion, Double Shield TBM 17"disc cutters for different soil are essential components in the tunneling process for urban areas. They allow for safe excavation of tunnels without causing ground subsidence and ensure a high level of accuracy and efficiency in the excavation process.
