Screw rods 4a and 4a (see FIG. 4) are welded upward to the upper ends of the left and right impact transmission rods 4 and 4, and the upper ends of the left and right impact transmission rods 4 and 4 are attached to both sides of the connecting fitting 2. The screw rods 4a, 4a are inserted into the insertion holes of the left and right L-shaped metal fittings 11, 11 and fastened with the nut 12.

Further, as shown in FIG. 2, a column support 5 is fixedly provided at the center of the lower surface of the upper connecting fitting 2. As shown in FIG. 3, the column support 5 is formed from a cylindrical body having an inverted conical shape that opens downward, and is closed by welding a support plate 5a to the upper end, and the support plate 5a is connected to a connecting metal fitting. It is welded to the lower surface of No. 2.

With such a structure, when the support column 5 is mounted on the support column 10, the support column 10 can be easily inserted by the opening 5b (see FIG. 1) which is widened downward. In the inserted state, the support column 10 is housed in the upper tubular portion 5d and supported by the connecting fitting 2 via the upper support plate 5a.

As shown in FIG. 2, the column support 5 may have an inverted V-shaped incision (incision 5c) on one side of the opening 5b. This is because when the upper end of the column 10 is approached so as to cover the column receiver 5, the upper end of the column 10 is cut into the incision 5c.
After passing through, the insertion is facilitated by contacting the inner surface of the opening 5b.

Further, as shown in FIG. 2, lower connecting fittings 3 are fixed below the left and right impact transmission rods 4, 4.
The left and right impact transmission rods 4, 4 are connected by the lower connecting fittings 3.

On the other hand, as shown in FIG. 2, cylindrical hammers 8, 8 are inserted in advance between the left and right impact transmission rods 4, 4 between the upper and lower connecting fittings 2, 3. (See FIG. 6).

The cylindrical handles 7, 7 are inserted into the upper portions of the hammers 8, 8 and fixed by screws 8c.

As shown in FIG. 6, the hammers 8 and 8 have a connecting fitting 8a which is curved so as to form a curved portion 8b for allowing the support column 10 to pass therethrough similarly to the lower connecting fitting 3.
Connected to each other by. Further, the fixing strength of the hammers 8 and 8 is ensured by interposing the reinforcing plates 8d and 8d at both ends of the connecting fitting 8a.

With such a structure, the operator grips the handles 7 and moves the hammers 8 and 8 up and down to give the impact force of the hammers 8 and 8 to the impact receivers 6 and 6 located below. You can

In this case, as shown in FIG. 2, the stroke S for vertically moving the hammers 8, 8 has substantially the length of the left and right impact transmission rods 4, 4. However, in FIG. 2, since the rope 14 described below is fixedly installed below the upper connecting fitting 2, the stroke S of the hammers 8, 8 is
This is the distance between the fixed portion 14a of the rope 14 and the strike receiver 6.

With such a structure, the stroke S of the hammers 8, 8 can be made much longer than that of the conventional cylindrical structure, and the hammers 8, 8 can slide on the impact transmission rods 4, 4. Since it is movably inserted, the hammers 8 and 8 cannot be disengaged from the impact transmission rods 4 and 4.

Further, by making the diameter of the handle 7 smaller than the diameter of the hammer 8, when the hand holding the handle 7 moves up and down, there is no possibility of hitting the impact receiver 6 and injuring it.

A rope 14 is provided near the lower part of the column support 5 between the fixed portions 14a fixed to the left and right impact transmission rods 4, 4 with some slack. This rope 14 can guide the insertion of the support column 10 into the support column 5. That is, as shown in FIG. 4 (c), the upper end of the column 10 can be directly inserted into the column receiver 5 by moving the driving tool 1 downward while the column 10 is in contact with the rope 14. It is possible.

The rope 14 can prevent the column 10 from coming off. As shown in Fig. 4 (d), the rope 1 is inserted in the middle of the pillar 10 inserted in the pillar receiver 5.
When the hammers 8 and 8 are moved up and down while being hit by
This is because the rope 14 causes static friction with respect to the column 10 and can prevent the column 10 from moving.

Further, since the driving tool 1 is supported by the support pillar 10 by the two-point support by the uppermost support pillar support 5 and the rope 14 on the way, the unstable operation of holding the handles 7, 7 with both hands on board. In the posture, the column 10 can be used as a support for standing.

A method of using the strut driving machine 1 configured as described above will be described with reference to FIGS. 7 (a) to 7 (d).

First, as shown in FIG. 7 (a), the operator holds the rod of the water flow excavating nozzle 21 while standing on the ship, and the tip of the nozzle 21 is erected at a predetermined position on the bottom of the water. The vertical hole 22 is dug by ejecting high-pressure water from the tip of the.

Next, as shown in FIG.
Is inserted into the vertical hole 22 along the nozzle 21, and then the nozzle 21 is removed. Up to this point, it is the same as the conventional example.
