The chuck body is equipped with a rocking mechanism such as a pair of rocking cylinders that give a rocking motion to the casing through the chuck body, and the casing can be pushed down by a vertically movable cylinder while giving rocking motion to the casing during excavation. Or, in the case of extraction, a casing driver is provided that pushes up the casing.

。Therefore, since this construction method uses a casing, it is possible to create cast-in-place piles with less soil and sand mixed in on the outer periphery, and with a large bearing capacity.Compared to other cast-in-place piles, it is reliable and has the highest allowable bearing capacity, while also reducing noise. However, pushing the casing requires a strong pushing force due to large surrounding friction such as earth pressure, and has the disadvantage of poor workability. In view of the above, the present invention is intended to deal with this problem.That is, it uses a pushing mechanism and a swinging mechanism in combination, and the swinging mechanism swings the casing. The purpose of this is to promote work efficiency, prevent dangers caused by remote control, and make it a smaller unit. Hereinafter, one embodiment of the casing driver according to the present invention will be explained in detail based on the attached drawings. 01 is a base, which is provided with an insertion hole 2 cut out at one end and through which the casing A passes; , Two rods 3.3 are installed in the horizontal direction so as to extend from side to side, and a way (W) is placed on these rods 3.3 to stabilize the base L together with a stabilizing rod 4, which will be described later. .

ーシングＡにがかる土圧による摩擦を抵減させる。In the figure, reference numeral 14 denotes a guide member provided on the chuck body 7. As is clear from the above structure, the present invention is based on a plurality of vertically movable cylinders 6. It is pushed into the chuck body 7 in the opening supported by the support pieces 6' and 6' and positioned on the ground surface through the insertion hole 2 of the base 1, and the chuck body 7 is clamped to the casing A by the opening/closing cylinder 9. After the casing A is set in a vertical position by the vertically movable cylinders 6' to 6, the pair of swinging cylinders 12 and 12' are operated alternately to swing the casing A up and down via the chuck body 7. The recasing A is pushed into the movable cylinders 6 to 6', the soil inside the casing A is removed and excavated using a hammer graph, and after the cylinders 6 to 6' are pushed to the lowest position, the opening and closing cylinder 9 is moved. to open the chuck body 7, and then move the chuck body 7 to the cylinders 6 to 6'
The rear chuck body 7 is clamped to the casing 7, and the above-mentioned work is repeated to excavate one by one.During the pushing, the rocking cylinders 12 and 12' are alternately rocked by the earth pressure applied to the casing A. Reduce friction.

押込み力は小さくてもよく、作業が増進できる。Furthermore, in order to remove the casing A after excavation, the casing A is sequentially pulled out while performing a reverse operation to the pushing operation described above.In this case, the casing A is also given a rocking motion.As described above, the present invention uses a casing When pushing in and pulling out casing A, the casing is pushed in and pulled out using a vertically movable mechanism, which uses a swinging mechanism that alternately swings the casing. In order to do this, the pushing force can be small because the friction of the earth pressure applied to the sink is reduced, and the work can be improved.
