Limta belling bucket with reamer cutting

Product Introduction
Limta belling bucket is a drilling tool to increase the pile diameter in the foundation，Enlargement the bottom of the borehole. By increasing the anti pulling force of the pile, the stability of the pile can be enhanced.
Working principle
1. Use a conventional drill bit to drill to the design depth.
2. Expand the tool arm by the pressure that the rig provide and rotate the cutting to enlarge the bottom.
3. Collapse and exit: After expanding the bottom, retract the tool arm by pull up the bucket and remove from the hole.

Application scenarios
High rise buildings: pile foundation engineering that requires high bearing capacity.
Bridge piers and abutments: structures that require high resistance to pull-out forces.
Wind power foundation: Large diameter expansion piles enhance stability.
Applicable strata

Suitable for stable and non collapsing formations, hard stratum, frozen soil and plastic clay layer;
