PROBLEM TO BE SOLVED: To provide a sample collecting device capable of collecting certain samples in a plurality of positions differing in a radial direction relative to a rotating shaft at a time.SOLUTION: A device includes: a rotating shaft 23 that is inserted into an improving body before hardening and is rotated; holders 29, 30 in which a base end part is integrally fixed in a lower end part of the rotating shaft 23 and the longitudinal direction projects in an outer peripheral side; a mold 31 that forms a cylindrical shape and is held such that an axial direction orthogonally crosses longitudinal directions of the holders 29, 30; a stopper 28 protrusively formed in the rotating shaft 23 so as to form a predetermined angle θ within a horizontal surface relative to the holders 29, 30; a boss part 32 rotatably and loosely fit to the rotating shaft 23; and lid plates 33, 34 in which the base end part is fixed to the boss part 32. The lid plates 33, 34 can take a closing position for closing an end face of the mold 31, and an opening position for opening the end face of the mold 31 while abutting on the stopper 28.SELECTED DRAWING: Figure 2
【課題】 回転軸に対して半径方向に異なる複数の位置にある試料を一度に採取できる試料採取装置を提供する。【解決手段】 本装置は、未硬化の改良体に挿入されて回転する回転軸２３と、基端部が、回転軸２３の下端部に一体的に固定され、長手方向が外周側に突出するホルダ２９、３０と、筒状をなし、軸方向がホルダ２９、３０の長手方向に直交するように保持されるモールド３１と、ホルダ２９、３０に対し水平面内において所定角度θをなすように回転軸２３に突設されるストッパ２８と、回転軸２３に対し回転自在に遊嵌されるボス部３２と、基端部が、ボス部３２に固着される蓋板３３、３４とを備える。蓋板３３、３４は、モールド３１の端面を閉鎖する閉鎖位置と、ストッパ２８に接してモールド３１の端面を開放する開放位置とをとり得る。【選択図】 図２
