Rotary Drilling Rig Tools Core Barrel With Roller Bits For Foundation Construction
Core Barrel with Roller Bits
A core barrel with roller bits is a specialized drilling tool used in geological exploration and engineering projects. It's designed to retrieve intact core samples from beneath the earth's surface for analysis.
Key components:
- Core barrel: The main body of the tool, which houses the inner tube and outer tube.
- Roller bits: The cutting elements at the bottom of the barrel, typically made of tungsten carbide or steel. They rotate and grind against the rock formation, creating a cylindrical hole.
- Inner tube: A hollow tube that collects the core samples as they are cut.
- Outer tube: A protective sleeve that surrounds the inner tube and prevents the core from being damaged.
