| 摘要 | PURPOSE: To accurately collect contaminants by installing a tubular casing, a tubular sampling part, a device to insert the easing and sampling part beneath the ground surface, and a device to remove the soil needlessly cut. CONSTITUTION: This device is provided with a casing part 16, an adaptor connector 14, and a sampler part 10, wherein they are rotated integrally with a casing driving motor 24 and at the same time, a cutter blade 32 in the center of the casing is driven with a motor 36. A material cut off by the blade 32 is discharged to a ring-shaped part 46 through a discharge port 44, and then is flushed upward by a fluid from a high-pressure fluid source 56 through a discharge jet 62 disposed on a circular cutter blade 50. A hood 64 is installed on the ground surface to seal a between the ground surface and the device, and at the same time, a cooling fluid source 82 such as liquid nitrogen is supplied to a thermal insulating jacket 80 to prevent the emanation of volatile components. | ||||||
