Open Tunnel Boring Machine Shield Cylinder
Shield cylinder is a key component used in shield operation in open tunnel boring machine. In the process of shield tunneling, the shield cylinder provides strong thrust and support force to ensure that the shield machine can smoothly traverse the formation and carry out excavation operations. This kind of cylinder usually has high strength and stiffness to adapt to the complex mechanical environment in the process of excavation. The sealing performance and wear resistance of the shield cylinder are also key factors to ensure its long-term stable operation. In addition, the structural design of the shield cylinder also needs to take into account the overall layout and space constraints of the TBM to ensure that it can be installed compact and efficient on the TBM.

The shield cylinder for open tunnel boring machines (TBM) is a vital element in tunneling projects, offering crucial support to the shield across diverse geological conditions such as sand, clay, and silt. It proves particularly advantageous in unstable ground scenarios or areas where water ingress poses a threat. Constructed from high-strength steel, these cylinders are designed to endure the substantial pressures and forces encountered during tunneling activities. Additionally
