The drilling rod 1 is connected at its upper end to a rotary drive device 2 suspended from a mast so that it can be moved up and down, and is provided with a drilling bit 3 at its lower end and a stirring screw 4 at its upper end. This drilling rod 1
is equipped with a movable intermediate steady rest device 5 suspended from the top of the mast, a screw steady rest device 6 suspended from the mast and adjustable in height, and the lower ends of the three rods 1 are connected to connecting metal fittings. They are connected by 7.

6 guide ropes 12 with a weight 11 attached to the lower end through the
are arranged. The guide rope 12 hangs down along the outer circumferential surface of the cylindrical curtain 8, and is inserted through a locking ring 13 protruding from the ring 9 and the outside of the lower screw steady stop device 6, as shown in FIGS. 3 and 4. The ring 9 is locked to the guide rope 12 so as to be slidable in the vertical direction.

When the rope descends and lands on the ground, the guide rope 12 is rolled up to raise the weight 11 to a slight height from the ground surface, so that the load tension of the weight 11 always acts on the guide rope 12. Also,
As shown in FIGS. 2 and 4, the intermediate steady rest device 5 and the lower screw steady rest device 6 are slidably engaged with two guide rods 14 attached to the mast so as to be movable up and down.

れが抑制でき安定性が向上する。FIG. 5 shows the state in which the ground is excavated, and the bellows-shaped cylindrical curtain 8 is attached to the excavation rod 1.
Following the digging or pulling up, the rod contracts or expands to cover the drilling rod 1 and prevent mud from scattering. Furthermore, since the ring 9 is slidably locked to the hanging guide rope 12 with a weight attached to the lower end, the swinging of the cylindrical curtain 8 can be suppressed and stability can be improved.
