摘要： PURPOSE: To clearly verify the vertical direction of a tubular member including a core by allowing an inner tube element used for a double tube device for taking soil samples with a different end part to make connection to a plurality of identical inner tube elements that are connected by a tube member made of a fiber-reinforced plastic. CONSTITUTION: Both end parts that can be identified being connected by a tube member made of a fiber-reinforced plastic are provided at an inner-tube element 1, and an orientation marking 2 is executed to the entire length of the tube member before covered with a plastic thin layer, thus minimizing the number of operations in a work site and clearly verifying the vertical direction of the part of the tube member including a core in all cases.

摘要： PROBLEM TO BE SOLVED: To quickly sample soil specimens without disturbing the sampled soil specimen by releasing the fixing of the edge bit of a closed sampler regardless of sampling depth. SOLUTION: A lock fitting 21 biting into the recess groove 22 of the inner face of a core tube 10 is slipped off from the recess groove by being drawn near the center by pulling up of a lock connected to an overshot catcher 42. When the sampler 1 is further excavated underground, soil pushes up the fixing- released bit 12 to be put into the core tube 10, and the soil specimens are sampled. At the same time, the vinyl tube 15 of the edge of the core tube 10 is drawn out to package the soil specimens.
