Cutting Ring with Rock Drilling Bits:
-
Functionality: The cutting ring is equipped with specialized rock drilling bits designed to alleviate internal stress within the rock formations.
-
Drilling and Breaking: These bits execute precise stage breaking while simultaneously drilling, ensuring efficient penetration and fragmentation of the material.
-
Barrel Design:
- The small barrel is optimized for coring operations, allowing for effective sample retrieval.
- The large barrel is tailored for stage breaking, facilitating the efficient fragmentation of larger rock masses.
-
Layer Compatibility: This system is effective in various geological conditions, including backfill layers, moderately weathered rock, and solid bedrock.
Conclusion
A core barrel with bullet teeth is a specialized drilling tool used to create an annular (ring-shaped) opening in rock or concrete (including reinforced concrete). It features bullet-shaped teeth, often with a staggered arrangement, that are designed to efficiently penetrate and break up the material. This type of core barrel is particularly useful in urban piling projects and other applications where drilling into hard or reinforced materials is required.
