Abstract
The method of making holes in the soil includes driving a capsule into the oil by percussive action and filling the capsule with the soil. Then the driving of the capsule into the soil by percussive action is continued, with the soil passing therethrough. The capsule is then withdrawn from the hole, and the soil that has passed through the capsule is also removed from the hole, whereafter the soil is removed from the capsule itself. The apparatus for making holes, performing the disclosed method, comprises a capsule capable of receiving the soil therein, having an open soil intake end, its opposite end being a partly open one. The capsule incorporates a percussive mechanism.
