Abstract
PURPOSE:To safely draw a pile with good efficiency by a method in which the center of a pile is drilled by auger, a water jet device is inserted into the vertical hole so formed, high-pressure water is jetted to cut off the pile to pull it up. CONSTITUTION:The center of an in-situ pile 1 is drilled by auger 3, etc., to form a vertical hole 6 through the pile 1. The auger 3 is pulled up, and the surrounding ground of the pile is excavated by a steel tube of a larger diameter than the pile 1. A water jet device 5 is inserted into the vertical hole 6 and high-pressure water jet is jetted from a nozzle 5a to cut off the pile 1 with reinforcing bars 2. The cut pile blocks 1A are pulled up repeatedly to draw up the pile 1. The drawing operation of the pile can thus be attained with good efficiency with less labor in a short time, at low cost.
