METHOD AND DEVICE FOR HORIZONTAL SAMPLING OF EARTH FREE FROM DISORDER

摘要

PURPOSE:To obtain a body to be tested which has uniform quality and excellent conditions, by collecting a thin layer of earth by standing only a cylinder part, which has reaches a target layer of earth, at right angles to a longitudinal hole and by pressing it into the layer in parallel to the direction of the layer of earth. CONSTITUTION:A longitudinal hole I penetrating a layer of earth containing collected earth is dug from the surface of the earth and only the part of the layer of the collected earth is widened by digging so that a collector is rotatable. Then, the collector is inserted until a dug position II, and the operation direction of a collecting cylinder is set in the direction of the layer of the earth and pressed into the layer; after the cylinder is charged with the earth, it is extracted from the layer and changed in direction to the original insertion attitude. The whole device is drawn out to the surface of the earth, thus collecting the earth. For this purpose, the collector is equipped with a collecting cylinder 3, a pressure cylinder 2, a support pipe 1, an arm 9, a direction transition device 5, a remote operating device, and a power transmission line.
