Document Type and Number:
WIPO Patent Application WO/2023/282201
Kind Code:
A1
Abstract:
According to the present invention, in order to increase the utility of a pile press-in device in areas with lower height limitations, a pile press-in device 10 comprising a saddle 1, a clamp device 2 that holds upper end parts of existing piles P1-P4, a mast 4 that is provided standing in a turnable manner, and a chuck device 6 that is supported by the mast with a raising and lowering device 5 therebetween and that holds a pile P0, is used for implementation in a pile press-in execution method wherein a pile row is extended on the ground by grasping existing piles with a clamp device and generating reaction force, holding a pile with a chuck device and pressing said pile into the ground via a raising and lowering device, and continuously pressing in piles while moving on the pile row formed by the existing piles. A pile press-in device is applied wherein the chuck device is capable of tilting about a chuck tilting axis CY that intersects with the mast and that is in the direction in which the mast and the chuck device line up. Via the turning of the mast and the tilting of the chuck device, a pile supplying step is implemented wherein a pile is supplied lying sideways, inserted into the chuck device, and held, while the chuck device is in the condition of being laid sideways and projecting outward to the side of the pile row when viewed from the axial direction of the existing piles.
