Double Shield Tunnel Boring Machine Auxiliary Thrust Cylinder
An auxiliary thrust cylinder is an auxiliary propulsion component in a dual shield tunnel boring machine, usually used to provide additional thrust in specific situations. For example, the auxiliary thrust cylinder can provide the necessary thrust support when hard formations are encountered during the driving process or when the driving direction needs to be adjusted. The design of the cylinder is flexible and can be customized and adjusted according to actual needs. Materials and manufacturing processes have also been carefully selected and optimized to ensure cylinder stability and durability in harsh environments.

The auxiliary thrust cylinder is an essential element in tunnel boring machines, particularly in double shield tunnel boring machines (TBMs). Located on both sides of the gripper shield, these hydraulic cylinders extend to push the gripper shield and the cutterhead forward, enabling the TBM to excavate the tunnel effectively. These auxiliary thrust cylinders complement the main thrust cylinders, supplying the necessary force to propel the entire machine forward. They are particularly beneficial in unstable ground conditions where the main thrust cylinders may lack sufficient thrust to move the TBM ahead. Additionally, they assist the TBM in overcoming obstacles like boulders or hard rock formations.
Features of Double Shield TBM Auxiliary Thrust Cylinders
Auxiliary thrust cylinders are generally large and powerful components. They are engineered to handle high pressures and significant loads.
Key features of Double Shield TBM Auxiliary Thrust Cylinders include:
- Constructed from high-strength materials, such as alloy steel.
- Specially heat-treated and welded for high-fatigue life under pressure and heavy loads.
- Designed to endure high vibration conditions during TBM operation.
- Wide temperature resistance range (-20¡æ to +80¡æ).
- Customizable to meet specific TBM and tunneling project requirements.
