置される。2. Description of the Related Art When a multi-shaft auger device is used to construct an underground continuous wall, the greater the number of screw shafts in the auger device, the higher the construction speed and construction accuracy (watertightness). By the way, as is well known, an auger device consists of a drive mechanism including a motor and a speed reducer, and an excavation rod having a protruding screw or stirring blade whose end is connected to the drive mechanism. Such an auger device uses heavy machinery such as a crawler as its base machine, and is attached to a leader mast that is provided on the base machine so as to be able to rise and fall freely, and the drive mechanism winds the top sheave at the upper end of the leader mast. A drilling rod, suspended by a descending wire and connected to a drive mechanism, is placed along the leader mast.

込んで行っている。When the motor in the drive mechanism is driven, the drilling rod is slowly rotated via a speed reducer, the ground is cut in a conical shape by the drilling head at the tip, and the drive mechanism is moved to the leader mast while feeding out the wire. The drilling rod is inserted as it descends along the line. When the drive mechanism has descended to near the lower end of the leader mast, separate the upper end of the drilling rod and the drive mechanism, lift only the drive mechanism to the upper end of the leader mast, and insert a new excavator between the already inserted drilling rod and the drive mechanism. Add more rods to cut deeper into the ground. In this case, the new drilling rod is added by lifting the new drilling rod with a crane or the like.

ダマストに昇降自在に取り付けられる。By the way, if the drilling rod is a single shaft, only a circular hole is formed, so a multi-shaft auger device is used for construction of an underground continuous wall that requires an oblong circular drilling hole. Ru. In the case of this multi-shaft auger device as well, as in the case of the single-shaft auger device, a drive mechanism consisting of a motor and a speed reducer is attached to the leader mast so as to be movable up and down.

や時間がかかるものである。[Problem to be solved by the invention] However, especially in the case of a multi-shaft auger device, the drive mechanism is arranged side by side for the number of drilling rods and moves up and down along the leader mast, and its weight is greater than that of a single-shaft auger device. It's quite large in comparison. In particular, in order to drill holes in hard ground, the motor and speed reducer must be powerful, making the machine even larger. In addition, the drilling rod itself becomes rigid and thick. When adding or retrieving drilling rods, the heavy drive mechanism is located at the top of the leader mast, so the entire center of gravity shifts to a higher location.
This leads to an unstable situation in which the entire base machine and the base machine are likely to fall over. In addition, the work of connecting or disconnecting the drilling rod from the drive mechanism is dangerous because it requires work at heights, and heavy equipment such as a crane must be used separately to suspend the drilling rod, which requires complicated work on site. Therefore, it takes time and effort.

The purpose of the present invention is to provide an auger device that can be automated to shorten time and save labor.

In that case, the drive unit 5 supported by the elevator 4 in the portal rig 1 so as to be able to change the support angle is of a single axis. Further, the rod rack 9 stores single-axis excavation rods laid horizontally and stacked vertically in the horizontal direction. The other rod feeding devices 10 and automatic take-out mechanisms 11 are similar to those for multi-axis use.
【００３２】使用法および動作については単軸の場合も
前記多軸の場合と同様なので説明を省略する。[0032] The usage and operation are the same in the single-axis case as in the multi-axis case, so the explanation will be omitted.

なくし安全性を高めることができる。As described above, the auger device of the present invention can shorten time and save labor by automating the work of attaching and detaching the drilling rod. In particular, in the case of a multi-axis machine, the number of drilling rods is large, and the drive unit is also large and heavy, but the present invention can improve safety by eliminating the need for work at heights for attaching and detaching the drilling rods.
