| 摘要 | PURPOSE:To collect a sample without disturbing a stratum with a connected state, by slidably coupling a piston, which is linked to the tip of a divided rod, to the inside of a tubular collecting pipe. CONSTITUTION:A rod 1 is constituted by connecting many pieces of divided rods 2. A piston 4 is linked to the tip of the rod 1. An engaging part 5 is provided. The piston is slidably coupled to the inside of a tubular collecting pipe 6. A collecting port 8 of the collecting pipe 6 is pushed into a soft stratum, from which a sample is to be collected, by manually operating the rod 1. When the piston 4 is lifted, the pipe 6 remains in the stratum, into which the pipe is pushed in. A sample space is formed in the pipe 6. Then, the collecting pipe 6 is pushed in the stratum by the length of the formed collecting space by the rod 1. The sample of the stratum is put into the pipe 6. Under this state, the pipe 6 is lifted. Then the sample in the pipe 6 can be collected. Therefore, the samples can be collected continuously without disturbing the stratum. | ||||||
