SAMPLING METHOD OF SOIL SAMPLE AND SAMPLING DEVICE
PROBLEM TO BE SOLVED: To provide a sampling method of soil samples for quickly lifting frozen soil without cutting work (coring) of the circumference of a frozen soil sample (frozen soil column), and a sampling device.SOLUTION: A sampling method of soil samples comprises steps of: inserting a freezing pipe into soil for collecting soil samples; freezing the soil samples by cooling the freezing pipe inserted in the freezing pipe insertion step and freezing the soil samples around the freezing pipe in a roughly reverse frustum shape around the axis of the freezing pipe; and collecting the soil samples by drawing out the freezing pipe together with the frozen soil samples from the ground. The collecting step of the soil samples is performed without coring the periphery of the frozen soil samples.SELECTED DRAWING: Figure 1
【課題】 凍結した地盤試料（凍土柱）外周の切削作業（コアリング）なしで迅速に凍土を引揚げる地盤試料のサンプリング方法及びサンプリング装置を提供すること。【解決手段】地盤試料を採取する土中に凍結管を挿入する凍結管挿入工程と、該凍結管挿入工程で挿入した前記凍結管を冷却し、この凍結管の周囲の地盤試料を該凍結管を中心軸として略逆錘台状に凍結させる地盤試料凍結工程と、前記凍結管を凍結した地盤試料と一緒に土中から引き抜き、地盤試料を採取する地盤試料採取工程とで構成され、前記地盤試料採取工程は、前記凍結した地盤試料の周囲をコアリングせずに行う。【選択図】 図１
