The bundle 9, which is fitted into the slide connector 10, is fitted into the bundle mounting groove 13 of the cylinder 19, and the hook 4 is hooked onto the sleeve 14, and the main device is erected at a predetermined position.

Next, a drive motor (not shown, the same applies hereinafter).

), the square shaft 7 rotates, and at the same time, the digging awl 11 and the slide connector 10 rotate, so the bundle 9 rotates the cylinder 19 and pushes it into the ground together with the digging awl 11.

At this time, in the case of soft ground, the spiral excavation blade 12 pushes the earth and sand around the cylinder 19 and consolidates it, and in the case of hard ground, the earth and sand is discharged upward.

Digging a hole using the drilling awl 11 and cylinder 19 (a hole with a depth equal to the length of the cylinder).

) is completed, the drill is pulled out from inside the cylinder 19, the drilling awl 11 is removed from the tip of the square shaft 7, and it is replaced with a longer drilling awl 30, and the hole is dug to a predetermined depth.

Of course, at this time, there is no rotary digging action of the cylinder 19.

Next, the drill with the drilling drill bit 30 attached is pulled out, various types of consolidation materials are thrown into Omukai in order to increase the consolidation of the soil at the tip of the pile, and the drill is inserted again and rotated in the opposite direction to push the consolidation materials and support the pile. Try to increase your power.

During this work process, when the drill is pulled out from inside the cylinder 19, if the slide connector 10 and the guide disk 2 are not present, the drill swings inside the cylinder 19, and the square shaft 7 hits the upper end of the cylinder 19, and the tip part of the drill hits the top of the cylinder 19. Although the cylinder 19 is damaged by hitting the inside and noise is emitted, the slide connector 10 remains attached to the head of the cylinder 19 (slides on the square shaft 7 and descends downward).

), the deflection of the square shaft 7 is prevented in this part and does not hit the cylinder 19, and the guide disk 2
Although the diameter of the cylinder 19 is slightly smaller than that of the cylinder 19, a plurality of guide rollers 3 which rotate in contact with the inner wall of the cylinder 19 are provided on the upper periphery of the guide disk 2, so that the guide disk 2 and the drilling awl 11 are .30 is prevented from hitting the inside of the cylinder 19, neither damaging the cylinder 19 nor emitting any sound.

It is also possible to smoothly pull out the drill from the cylinder.

When the drill is pulled out from inside the cylinder 19, the drive motor and the connecting part 6 are uncoupled, and the required pile or shaped steel 31 is hoisted up by a crane and inserted into the cylinder 19 as shown in Fig. 4C. When the top of the cylinder 19 is placed inside the cylinder 9, the hydraulic cylinder 32 is used to open the cylinder 19 as shown in Fig. 4C.
This is pushed to a predetermined depth using the reaction force.

The reaction force of the cylinder 19 is applied to the hook 3 provided on the hydraulic cylinder 32.
3 on the sleeve 14 of the cylinder 19 to obtain this.

If the top of the pile or shaped steel 31 protrudes outside the cylinder 19 (this will happen for a while).

) uses a jack case 18 as a pile driving auxiliary device as shown in FIG.

That is, the protruding top of the pile or shaped steel 31 is hammered with a pile driving hammer (not shown).

) If you hit the ball with
8 is placed on the cylinder 19, and the sleeve 15 is placed on the sleeve 14.
Place the hook 16 on the sleeve 14 and fix it with a pin 28 so that the hook 16 does not come off.

Next, using a crane, place the hydraulic cylinder 29 into the jack case 18, place its lower guide frame 25 on the head of a pile or shaped steel 31, and insert the pin 23 into the upper support frame 24 and adjustment hole 17 to lock it, and the hydraulic cylinder is closed. 29 to push in the pile or shaped steel 31.

At this time, the hydraulic cylinder 29 may be lowered using the adjustment hole 17 as the pile or shaped steel 31 is lowered.

Of course, the reaction force of the cylinder 19 is used for this pushing, and the reaction force is generated by the engagement between the sleeve 14 and the hook 16 and the sleeve 1
4 by placing the sleeve 15 thereon.

Once the pile or shaped steel 31 has been pushed to a predetermined depth, the hydraulic cylinder 29 and jack case 8 are removed by reversing the above procedure.

In some cases, shaped steel such as H steel or sheet piles is pushed in, but in many cases, used rails are also pushed in.

When such shaped steel or rail piles are pushed in, their orientation may become erroneous for some time and must be corrected.

This direction correction work is performed as follows.

That is, the drilling drill 11 or 30 is removed from the drill, the drill is connected to a drive motor and lifted up, and the head of a shaped steel or the like is inserted into the direction correction groove 1 provided at the tip of the drill and rotated by the drive motor. Correct the direction.

When the pushing and direction correction of the pile or shaped steel 31 is completed in this way, the bundle 9 of the slide connector 10 is rotated in a circle.
If the cylinder 19 is attached to the bundle attachment *13 and the cylinder 19 is reversely rotated by the drive motor, the spiral excavation blade 12 will be attached to the cylinder 1.
The earth and sand around the pile or shaped steel 31 is consolidated and raised.

At this time, if earth and sand or soil improvement material etc. released on the ground are thrown around the piles, etc., the surroundings of the piles, etc. will be further strengthened, and the horizontal and vertical supporting capacity of the piles, etc. will be increased.

Once the cylinder 19 has been completely extracted, the hook 4 can be hooked onto the sleeve 14 and the cylinder 19 can be pulled up and moved to the next piling location.

Even when the cylinder 19 is rotated in the opposite direction and the soil around the pile etc. is consolidated and pulled out, the action of the slide connector 10 and the guide roller 3 prevents the square shaft 7 from swinging within the cylinder 19 at all. Damage to the cylinder 19 due to vibration can be prevented, and the guide roller 3 also prevents the cylinder 19 from being damaged.
rises smoothly.

As described above, when driving piles, shaped steel, etc. using the pile driving device of the present invention, it is possible to perform the following steps: digging the required pile holes, driving the piles, etc., consolidating the tip of the pile, etc. and the surrounding soil, and driving. This method has the great advantage that all work processes such as correcting the orientation of piles, pulling out cylinders, etc. can be carried out extremely efficiently and accurately, with no noise or vibration.
