PROBLEM TO BE SOLVED: To provide a collecting device for a sample in a soil, which collects the sample in the soil at pin point in an original position inside a ground, and also collects the sample in the soil in the vicinity of a side wall and in the lateral-directional original position, when collecting the sample in an enlarged foot protection bulb, a head attached with the collecting device, and the collecting method for the sample in the soil using the head.;SOLUTION: The collecting device 1 is constituted to be attached detachably to an expandable blade 15 expandable toward a diametric-directional outside by a hydraulic cylinder mechanism. The collecting device 1 includes an outer tube 2 and an inner tube 3 with a window hole 4 stored in the inside thereof. The outer tube 2 is attached to a side face of a cylinder portion 15a of a hydraulic cylinder of the expandable blade 15. A tip of the inner tube 3 is attached to a rod 15b of the expandable blade 15. The inner tube 3 is projected from the outer tube 2 by diameter-expanding the expandable blade 15, and the sample in the soil is collected from the window hole 4 into the inner tube 3 at the original position. The inner tube 3 is stored into the outer tube 2 by diameter-contracting the expandable blade 15, and the sample in the soil is recovered from inside the inner tube 3.;COPYRIGHT: (C)2011,JPO&INPIT
