earth pressure balance shield machine
The earth pressure balance shield machine is a sophisticated tunnelling equipment designed for excavation in a variety of ground conditions. Its main functions include maintaining earth pressure balance, supporting the tunnel face, and advancing the tunnel boring process. Technological features such as an adjustable pressure system, a rotating cutting head, and an automated lubrication system make it versatile and efficient. This machine is widely used in urban infrastructure projects, subway constructions, and water conveyance tunnels, providing a safe and effective solution for underground excavation.
