[0002] Subway shield is an important construction technology in urban subway construction. It is a construction method of underground tunneling. It uses a subway shield machine to dig underground. While preventing the collapse of the soft foundation excavation surface or maintaining the stability of the excavation surface, it safely carries out tunnel excavation and lining operations inside the machine. Its construction process requires first excavating a shaft or foundation pit at one end of a certain section of the tunnel, and then hoisting the subway shield machine into place for installation. The subway shield machine starts excavation from the wall opening of the shaft or foundation pit and advances along the designed tunnel line until it reaches the end of another shaft or tunnel in the tunnel line.
