The protection of the shield machine by the carbide shield knife is mainly reflected in the following aspects:
Cutting and excavation: Carbide shield cutting tools have high hardness and high wear resistance, which can quickly cut and excavate soil and rocks during the excavation process, improving excavation efficiency and reducing wear of the shield machine.
Support and stability: During the tunneling process, the shield machine needs to build (lay) the “shield” (referring to the supporting segment) of the tunnel. Carbide shield cutters can provide better support and stability, help the shield machine maintain a straight trajectory during the excavation process, reduce deflection and vibration, thereby reducing the risk of damage to the shield machine.
Reduce wear: Carbide shield cutting tools have high hardness and high wear resistance, which can reduce the wear on the shield machine’s cutterhead and tool holder during the excavation process, and extend the service life of the shield machine.
Reduce interference: The cutting ability and support stability of the carbide shield cutter can reduce interference and vibration during the excavation process, thereby improving the excavation accuracy and stability of the shield machine.
In summary, the carbide shield blade plays an important role in the shield machine. It can protect the shield machine from wear and damage of soil and rocks during the excavation process, and extend the service life of the shield machine.
