Shield Tunneling

Shield Tunneling

Shield Tunneling utilizes a shield that is placed in front of a tunnel whereby the main purpose is to keep the men working inside tunnels safe. Application of drilling fluids provides lubrication within the annular gap, leading to better stabilization towards the overall excavation procession of the frontal space with the utilization of fluid support. Using drilling fluids improves the transportation of cuttings during the excavation, as well as improve the cooling process of the cutting tools used during the Shield Tunneling process.

With the use of proper fluid lubrication, any form of collapse during the excavation process can be avoided. Making use of drilling fluids in Shield Tunneling also prevents slow excavation rates and reduces the chances of increased torque and high-pressure risks.
