SAMPLING DEVICE AND SAMPLING METHOD
To provide a sampling device and a sampling method capable of securely collecting an uncured sample in a foot protection portion constructed in a bottom of a pile hole in a state where sediment and the like are not included.SOLUTION: A sampling device is constituted of: a guide rod 3 extending in a vertical direction; and a sampling tube 4 arranged in a concentric manner at an outside of the guide rod 3. The sampling tube 4 ascends and descends along the guide rod 3 in a pile hole A. The sampling tube 4 descends together with the guide rod 3 in the pile hole A in a suspended state from a lower end portion of the guide rod 3, and ascends together with the guide rod 3 in the pile hole A in an overlapping state with the guide rod 3 in a concentric manner. As to the guide rod 3, a sampling port 4a is on a lower part lid 7 in a state where the sampling tube 4 is suspended below the lower end portion of the guide rod 3. The guide rod 3 comprises an upper part lid 8 closing the sampling port 4a in a state where the sampling tube 4 is moved by a specified dimension.SELECTED DRAWING: Figure 1
【課題】杭孔の底部に築造された根固め部の未硬化状態の試料を、土砂等が含まない状態で確実に採取できる試料採取装置及び試料採取方法を提供する。【解決手段】鉛直方向に延びるガイドロッド3と、ガイドロッド3の外側に同心円状に設置された試料採取管4とから構成する。試料採取管4は杭孔A内をガイドロッド3に沿って昇降し、ガイドロッド3の下端部より下方に垂下した状態で杭孔A内をガイドロッド3と共に下降し、かつガイドロッド3と同心円状に重なった状態で杭孔A内をガイドロッド3と共に上昇する。ガイドロッド3は、試料採取管4がガイドロッド3の下端部より下方に垂下した状態で試料採取口4aが下部蓋7上にあり、試料採取管4が規定寸法移動させた状態で試料採取口4aを閉じる上部蓋8をそれぞれ備えている。【選択図】 図1
