Abstract

PURPOSE: To strengthen joint between the outer periphery of a pile and the ground by injecting an accelerator into the circumferential part of the pile from the upper end position of a friction cutter.
CONSTITUTION: A screw auger, etc., are inserted into a pile 1 and then erected with the pile 1 on the surface of the ground. Then, a hose leading to an accelerator injection pump is connected to the upper end of a supply pipe 6, the screw auger is operated to excavate a pit of a size corresponding to the outside diemeter of the pile 1 ahead of the tip thereof, and then the pile 1 is gradually sunk into the pit. In this case, a hole of a size equal to the outside diameter of a friction cutter 3 is formed around the pile 1, and when the pile 1 is driven approx. 1m, and an accelerator injection pump is operated to inject an accelerator upwards through plural nozzles and a pipe 4 from a supply pipe 6 in such a way as to fill up voids formed between the pile 1 and the ground. In this way, the auger is gradually inserted by excavation, the pile 1 is sunk gradually, an accelerator is injedted into voids formed gradually around the pile 1 when the tip of the pile 1 reaches a support layer, and the support layer and the tip of the pile 1 are made into an integral body.
