Types of Core Barrels

Core barrels come in various configurations, each suited to specific ground conditions and project needs:

  • Core barrel with bullet teeth: Ideal for cutting through rock, concrete, or reinforced concrete—this type uses staggered bullet-shaped teeth for efficient penetration. It’s versatile for medium-hard formations and widely used in urban piling projects.
  • Core barrel with roller bits: Designed for very strong rock formations with compressive strengths exceeding 100 MPa, this version employs rotating roller bits to grind through dense materials. It’s perfect for deep foundations in challenging terrains.
  • Cross cutter core barrel: Used to break up remaining rock cores or penetrate hard, jointed rock with compressive strengths under 100 MPa—this type features a cross-cutting mechanism. It’s also effective for layers with boulders, ensuring clean boreholes.
  • Grabbing style core barrel: Equipped with a claw-like mechanism, this variant retrieves fragmented samples from fractured or loose formations. It’s valuable in geotechnical engineering and mining exploration where intact cores are hard to obtain.
  • Double and triple tube core barrels: These advanced designs include inner tubes to protect the core sample. Double tube barrels are standard for general exploration, while triple tube versions—with a split inner tube—optimize recovery in broken formations, achieving near 100% core retrieval.

Applications in Foundation Drilling

Core barrels are critical instruments across a range of foundation drilling scenarios:

  • Bored Piles: They skillfully create boreholes in tough rock or mixed soil, enabling the placement of reinforced concrete piles that support heavy structures, including bridges and high-rise buildings.

  • Geotechnical Investigations: Contractors employ core barrels to extract samples for the analysis of soil and rock, providing essential data for foundation design and ensuring stability in marine and coastal projects.

  • Marine Construction: In waterfront developments, core barrels successfully penetrate underwater rock layers, facilitating the installation of piles for structures like docks and seawalls.

  • Mining and Exploration: These tools facilitate the retrieval of core samples, which are vital for assessing mineral deposits and geological stability, thus supporting foundation planning in regions adjacent to mining activities.
