Document Type and Number:
WIPO Patent Application WO/2019/054678
Kind Code:
A1
Abstract:
The present invention relates to a pile head reinforcing structure using an excavation bit, which enables multi-stage reaming and to which a non-welded casing coupler is applied, and a pile construction method using the same, the structure and the method: mounting a non-welded casing coupler to the excavation bit, which enables multi-stage reaming, so as to perform boring and insert a casing at the same time, thereby promoting the simplicity and rapidity of construction; enabling the plurality of casings to be connected or separated by means of the coupler, thereby resolving problems caused by the welding and cutting of the casings during construction; and coupling a head reinforcement to the upper part of a pile without welding and burying the same in concrete of a foundation part so as to disperse a pullout load and a vertical load and relieve stress concentration, thereby enabling the stable foundation part for supporting an upper structure to be formed.
