とするコア採取器具のビット。The core tube is a double tube type consisting of an inner core tube and an outer core tube, and a joint tube is connected to the tip of the outer core tube by a screw connection, and rocks, etc. are cut by screw connection to the tip of the joint tube. A bit is attached and a boring rod is connected to the rear end, and an extension tube positioned corresponding to the joint tube is connected to the tip of the inner core tube, and the entire inner circumference of the extension tube is connected to the tip of the inner core tube. A recess is formed in the recess, and a cylindrical bag with a bottom is housed in the recess so that its axis becomes the central axis of the core tube.As the core is cut, the core moves inside the extension tube and the inner core tube. 1. A bit of a core collection device, which is a double-tube type core collection device that advances while pulling out a bag from a recess, characterized in that a threaded portion for screwing to the joint tube is formed on the outer surface.
