Next, a method for using the piling tool according to the above-described embodiment will be described.
(1) For long gardening sticks (see Fig. 5)
For example, the upper end portion of a pile 21 having a length of about 1.5 m placed vertically on the soil 20 is inserted inside from the opening 13 of the first pile insertion portion 11, and the grip portion 6 of the support portion 3 is pushed to one side. While holding the piling tool 1 in a vertical posture by holding it with the hand (opposite to the dominant hand), hold the weight 10 with the other hand (dominant hand), lift it along the slide guide bar 2, and lower it with a strong force. The operation of hitting the lower part of the support part 2 (the collision surface part 5A corresponding to the periphery of the slide guide bar 2 in the arm part 5) is repeated.

Then, every time a strong impact force is repeatedly applied from the bottom 15 of the first pile inserting portion 11 downward in the axial direction from the upper end 22 of the pile 21, the lower portion of the pile 21 is driven into the soil 20. . Since the first pile insertion part 11 is cylindrical, there is no fear that the pile 21 will come off during the work.
Compared to holding the stake 21 by hand and inserting it into the soil 20 by putting one's weight on it, the stake can be driven much more easily and quickly. If the pile 21 is longer, the work can be carried out while being placed on a stepladder or the like.

For example, the upper end of a pile 23 having a length of about 70 cm placed vertically on the soil 20 is inserted inside from the opening 14 of the second pile insertion part 12, and the grip part 6 of the support part 3 is held by one hand ( While holding the pile driving tool 1 in a vertical posture by holding it with the other hand (opposite to the dominant hand), hold the weight 10 with the other hand (dominant hand), lift it along the slide guide bar 2, and lower it with a strong force to the support part. 3 (collision surface portion 5A corresponding to the periphery of the slide guide bar 2 in the arm portion 5) is repeated.

Then, every time a strong impact force is repeatedly applied from the bottom 16 of the second pile inserting portion 12 downward in the axial direction from the upper end 24 of the pile 23, the lower portion of the pile 23 is driven into the soil 20. .
Compared to holding the stake 23 by hand and inserting it into the soil 20 by applying the weight, driving can be done much more easily and quickly. Since the second pile insertion part 12 is tubular, there is no fear that the pile 23 will come off during the work.

According to this embodiment, the upper end of a pile 21 having a length of about 1.5 m, for example, placed vertically on soil 20 is inserted into the opening 13 of the first pile insertion portion 11, and the support portion 3 While holding the pile driving tool 1 in a vertical posture with one hand, grab the weight 10 with the other hand, lift it along the slide guide bar 2, lower it with a strong force, and place it on the bottom of the support part 3 By repeating the operation of driving, it becomes possible to repeatedly apply a strong striking force from the bottom 15 of the first pile insertion part 11 from the upper end 22 of the pile 21 directly downward in the axial direction. Compared to plugging into the soil, it can be driven much easier and faster. If the pile 21 is long, the work can be carried out while standing on a stepladder or the like.

In addition, for example, the upper end of the pile 23 having a length of about 70 cm is inserted into the inside from the opening 14 of the second pile insertion part 12, and the support part 3 is grasped with one hand to set the pile driving tool 1 in a vertical posture. While holding the weight 10 with the other hand, lift it along the slide guide bar 2, lower it with a strong force, and hit it against the lower part of the support part 3. By repeating the work, the second pile insertion part 12 is It is possible to repeatedly apply a strong striking force from the bottom 16 from the upper end 24 of the pile 23 directly downward in the axial direction, so that the pile 23 can be driven in much more easily and quickly compared to gripping the pile 23 by hand and inserting it into the soil. can be done.

In the above-described embodiment, the length of the piling tool 1 is about 50 to 80 cm, but it may be longer.
Also, the grip portion 6 and the first pile insertion portion 11 may form an angle other than 180 degrees when viewed from the slide guide bar 2 .
Further, the arm portion 4 fixed to the upper end portion of the slide guide bar 2 is omitted, the support portion is composed of the lower arm portion 5 and the grip portion 6, and the cap is integrated with the upper end portion of the slide guide bar. The portion 7, the projecting portion 9, and the first pile insertion portion 11 may be fixed.
In addition, the arm portion 5 fixed to the lower end portion of the slide guide bar 2 is omitted from the grip portion side, leaving the collision surface portion 5A, and the support portion is replaced by the upper arm portion 5, the grip portion 6, the cap portion 7, and the protrusion portion. 9 may be used.
Also, the first pile insertion portion or the second pile insertion portion may be omitted.
