Abstract

PURPOSE:To sample soft soil without breaking it, by combining two semi-tubular bodies with each other and insering them separately. CONSTITUTION:Semi-tubular bodies 1 and 1' are combined with each other and engaged with each other by a locking mechanism 12 of a ring 6. To a threaded section 17 of an operating shaft 3, a similar operating shaft 18 is connected, and an operating pipe 19 is connected to a threaded member 15 and inserted into soft soil. Then, a valve plate 15 is lifted up, and insertion is stopped when it reached the prescribed depth, and when the operating shaft 3 is pulled up a little, the valve plate 5 returns to its initial position. And then, when a coupling device 8 is pressed down by means of the operating pipe 19, the ring 6 of the semi-tubular body 1' is disengaged and its descends along a guiding shaft 4. After a specimen is captured in the two semi-tubular bodies 1 and 1' in this manner, when the operating pipe 19 is pulled up, a ball 14 of a combined member 13 is bitten in-between a tapered hole 11 and the operating shaft 3, and then, the coupling device 8, the operating shaft and the semi-tubular bodies 1 and 1' are all pulled up.
