Introduction:

Core barrel belongs to one kind of drilling tools, compared with rock drilling bucket, core barrel is used for coring through rock shelves, especially for strong rock up to 100MPA or rock with deep cracks. Foundation construction works usually use core barrel in very strong rock formations with compressive strength above 100Mpa.

Core barrel can be divided into four types: Core barrel with pin teeth for reinforced concrete; Core barrel with replaceable blocks for strong rock up to 100Mpa; Core barrel with bullet teeth for strong rock up to 100Mpa or rock with deep cracks.
