Cone for sinking pipes for e.g. earth heat exchange into the ground, provided with blades for cutting through earth

摘要

The cone has a number of blades used to cut through the earth and is provided with at least one rib cooperating with a corresponding cavity in the pipe. A cone capable of cutting and boring action is used to sink pipes to a given depth in the ground, e.g. for vertical pipes used to carry out heat exchange with the surrounding earth. The cone has a number of blades (preferably four) that cut through the earth. At least one rib corresponding with a match cavity in the pipe is provided on the flange side of the cone.
