That is, the upper pile retracting/extracting device 17 fitted into the main pillar guide has a support member that is fitted into the guide and moves up and down by pulling a wire, and an auger screw that rotates within a range of 90 degrees with respect to the support member. It consists of a through-hole section of the Y, a hole section for gripping a pile with a planar substantially H-shape in front of the through-hole section, and a gripping mechanism for the pile connected to the gripping hole section, so that it can be excavated with an auger screw. However, it is possible to pull the wire and pull the pile firmly into the ground using the pile's gripping mechanism, and when the ground is soft, there is no need to use an auger screw.
The pile can be pulled into the ground by pulling a wire, and at the corner of the site, a hydraulic motor 29
gear 2 meshing with pinion 29b.
By turning 4b, the pile retraction/extraction device can be freely rotated horizontally within a 90° range around the main pillar and supporting member, so the pile retraction/extraction device can be rotated at the corner. The pile can be pulled into the ground by freely changing the direction in which the pile is pulled in, and since the pile gripping hole of the pile gripping mechanism is opened in an approximately H shape, the pile can be pulled forward or backward. The auger screw 1 can be grabbed and pulled into the ground, as shown in Figure 8.
2 can always be installed in front of the pile 22 to excavate underground, so the problem of the ground P' of the neighboring structure P collapsing and sinking can be solved.
