PENETRATION TESTING DEVICE APPLIED TO SWEDISH SOUNDING TEST AND CHUCK MECHANISM FOR PENETRATION ROD OF THE SAME DEVICE
PROBLEM TO BE SOLVED: To provide a chuck mechanism of a rod which withstands predetermined strength.SOLUTION: A chuck mechanism includes: a first member 60 having a first recess 16 extending in a vertical direction; a second member 61 having a second recess 17 extending in the vertical direction; and pressing means 63. The first recess 16 and the second recess 17 are faced to each other, and configured so as to be approachable/separable. The first recess 16 and the second recess 17 have contact surfaces 160, 161 and 170 which come in contact with the peripheral surface of a penetration rod. The contact surface of either the first recess 16 or the second recess 17 is formed into a substantially V shape in a planar view from two inclined surfaces. The contact surface of the other recess is formed on a circular-arch surface in a planar view or into a substantially V shape in a planar view from two inclined surfaces.
【課題】所定の強度に耐えうるロッドのチャック機構を提供する。【解決手段】チャック機構は、垂直方向に延びる第１凹部１６を備えた第１部材６０と、垂直方向に延びる第２凹部１７を備えた第２部材６１と、押圧手段６３と、を備え、第１凹部１６と第２凹部１７は、互いに対向しており接近・離間可能に構成されており、第１凹部１６及び第２凹部１７は、貫入ロッドの周面に当接する当接面１６０、１６１、１７０を備えており、第１凹部１６と第２凹部１７のいずれか一方の当接面は２つの傾斜面から平面視略Ｖ字状に形成され、他方の当接面は平面視円弧面あるいは２つの傾斜面から平面視略Ｖ字状に形成されている。【選択図】図９
