Abstract

The gravel drill in reference, by means of the inner rod 13, transfers the connector B for linkage of the double-tube C and the rock excavator 11 and the drilling cone 15 in front of the casing 12 loaded in the inner rod 13; the continuous double-tube D formed by casing 22 and the inner rod 23 of the polygonal linkage 23a. The gravel drilling by means of pushing by the double-tube C while turning only the inner rod 13 and after inserting K1, the casing 12 is left inside the insertion hole K1, while removing only the inner rod 13 from the insertion hole K1.
