Summary:PROBLEM TO BE SOLVED: To surely push a buried pipe into the ground, without causing deformation and breaking of the connection between a buried pipe, the shank rod of a rock drill and an inner rod nor causing noises nor failing to push the buried pipe, by pushing the buried pipe without the intervention of the shank rod. SOLUTION: A pushing adapter 32 provided in such a way as to surround a striking coupling 20 is disposed between the rear end face of a buried pipe 10 and the body end face of a rock drill 12 and the feeding power of the rock drill 12 is directly transmitted to the buried pipe 10 to push the buried pipe 10 into the ground. The striking force and rotating force of the shank rod 14 of the drill 12 are imparted to an inner rod 16 via the striking coupling 20, whereby drilling is effected using a drilling bit 22.
