Earth Drill Method (Bell Earth Method)

Large-diameter and deep drilling is possible! The four-wing excavation pit allows for the construction of an excellent bell-bottom shape.

The "Earth Drill Method (Bell Earth Method)" protects the hole walls using a standpipe and stabilizing fluid, while excavation is performed by rotating a drilling bucket to cut the ground and discharge the soil contained in the bucket to the surface. For shaft excavation, a construction method suitable for the ground (full casing, reverse, earth drill) can be selected. The highly sealed bucket ensures the reliable removal of slime from the bottom of the hole, and the powerful rotational torque allows for large-diameter and deep excavation. 【Features】 ■ Shaft excavation allows for the selection of a construction method suitable for the ground ■ The four-wing excavation pit enables the construction of an excellent bell shape ■ The highly sealed bucket reliably removes slime from the bottom of the hole ■ Powerful rotational torque allows for large-diameter and deep excavation *For more details, please refer to the PDF document or feel free to contact us.
