Micro Shield Tunneling Machine

The "underground dragon" shield machine quietly advanced. The YSTP4380 small-diameter earth pressure balance rock composite shield machine has an excavation diameter of 4.38 meters, a total length of approximately 80 meters, and a total weight of approximately 350 tons. It has a maximum propulsion speed of 80 mm per minute and a minimum turning radius of 90 meters. The tunnel mileage of this micro-shield Tunnel Boring Machine exceeds 2 kilometers, and the tunnel geology is primarily composed of gravel, sand, clay, and rock formations. Based on the geological conditions and requirements, a series of optimized designs have been implemented for the wear resistance of the shield machine's key bearings and seals to ensure safe and efficient excavation.
