PROBLEM TO BE SOLVED: To provide support burying equipment which can suppress a noise in burial when a small-diameter support such as a guard fence support is continuously buried, which can also adapt to the burial of the support in hard ground, and which enables the support to be rationally pulled out/buried in maintenance work etc. SOLUTION: A base part 6 of a burying machine, which is composed of a revolving table 4 and a sliding base 5, is mounted in a horizontally revolvable manner on a loading platform 3 of a tire-type traveling vehicle 2; a guide 7 is provided on the sliding base 5 in such a manner as to be capable of rising and falling; and a rotative driving device 8 and a striking-force generator 9 are installed in the guide 7. An upper device of an elevating machine such as the guide 7 is horizontally revolved, advanced forward and erected by a derricking cylinder 17, and a rotating head 11 is mounted on the head part of the support A. After that, the rotating head 11 is lowered by a sliding cylinder 13 while being rotated by the driving device 8, and sent downward in a pushed manner; and a lower part of the support is buried in the ground by a rotary press-in method. For example, when the ground is hard, the striking-force generator 9 makes the support buried in the ground by a striking method. COPYRIGHT: (C)2006,JPO&NCIPI
