PROBLEM TO BE SOLVED: To provide a boring and sleeve pipe pushing-in device capable of accurately moving a boring device from a wait position to a boring position, moving a sleeve pipe pushing-in device from the received position of a sleeve pipe to a sleeve pipe-pushed-in position for a hole bored from the received position of the sleeve pipe, and contriving simplification of a movement operation system. ;SOLUTION: A linear moving mechanism (b), a turning and moving mechanism (c) and a sleeve pipe stock device (f) are attached to the edge of the boom (a) of an excavator or the edge of an arm 5 to mount a boring device (d) to the linear moving mechanism (b). The boring device (d) is linearly movably constituted at a boring position and a wait position through the linear moving mechanism (b) to mount a sleeve pipe pushing-in device (e) to the turning and moving mechanism (c). The sleeve pushing-in device (e) is turnably constituted in a wait position capable of receiving a sleeve pipe 43 from the sleeve pipe stock device (f) through the turning and moving mechanism (c) and a sleeve pipe pushing-in position with the boring device.;COPYRIGHT: (C)1999,JPO
