Description of the Related Art When a pile is rotatably buried in a pile insertion hole formed in a construction ground, a pile head is inserted into a required position of a pile-consolidating portion built at a lower end of the pile insertion hole, and then a pile head is fixed. It is necessary to hold the pile in a suspended state until it is fixed at the position (that is, until the lower end portion of the pile is in a required anchoring state on the rooting portion).

の作業を行うことができるものである。That is, the heavy equipment a is provided with an auger motor d suspended vertically by a wire c on a tall support member b erected on the ground, and a rotating shaft of the auger motor d is provided on a rotating shaft of the auger motor d.
It is possible to selectively connect a drilling rod for drilling a pile insertion hole or a pile insertion rod for rotating and embedding a pile, and by using both rods properly, it is possible to perform both the work of excavating the pile insertion hole and the operation of rotating and embedding the pile.

Is provided with a cap g for chucking the head f1. As shown in FIG. 14 , the cap g has a cylindrical shape that is open downward and into which the pile head f1 can be inserted, and a lateral opening i is continuously provided on the peripheral surface at the upper end of the vertical opening h. An L-shaped locking opening j is provided.

An outwardly protruding locking pin k at the upper end of the pile head f1 is located at the upper end of the vertical opening h, and then the cap g
Makes a forward rotation F1 so that the locking pin k is moved to the side opening i.
And the pile head f1 is chucked. Conversely, when the cap g rotates in the reverse direction F2, the locking pin k is disengaged from the lateral opening i and the pile head f1
Is released from the chuck state.

各杭の杭頭部位置が精度よく揃わないことが多かった。Problems Regarding Construction Accuracy The time required to hold the pile with the pile lower end portion inserted in the rooting portion until the pile head is fixed at the required position must be set in accordance with the ground condition. . However, in the past, heavy equipment used for excavation of pile insertion holes and rotary embedding of piles was used for holding piles. Is usually set to about 20 minutes (the time when it was empirically thought that a certain amount of pile fixation was achieved), and after this time, the cap was removed from the pile head by reverse rotation of the auger motor. . For this reason, depending on the state of the ground, there were cases where piles could be firmly anchored, but piles often settled under their own weight afterwards, and the pile head position of each buried pile was not accurately aligned. There were many.

当を付けることができた。[0011] By the way, in the final burial state of the pile, if the cap that has chucked the pile head is exposed on the ground,
By visually observing the position of the locking pin in the lateral opening, the timing for releasing the chuck could be estimated for the time being. That is, FIG.
If the locking pin k was in contact with the lower edge n of the lateral opening as shown in FIG. 4 , it could be inferred that the pile was hung on the cap and the fixing was incomplete. Conversely, if the locking pin k is in contact with the upper edge o of the lateral opening as shown by the one-dot chain line in FIG. 14 , the pile is not hung on the cap, and thus even if the chuck is released I was able to get a good idea.

上げられてしまう最悪の事態を招くこともあった。However, if the cap is hidden in the pile insertion hole as shown in FIG. 13 in the final buried state of the pile, the position of the locking pin in the lateral opening cannot be visually observed. Had to decide when to release the chuck. As a result, the worst case where the pile was lifted when the cap was lifted with the intention of releasing the chuck sometimes occurred.

If it can be used for excavation and rotary burial of piles, it is possible to improve the utilization efficiency of heavy equipment (including its operators) and to reduce the construction cost accordingly. There was much room for improvement in terms of construction costs.
