METHOD FOR CARRYING OUT IMPROVED PILE

摘要

PURPOSE: An installation method of improved micro piles, an improved micro pile structure, and a pipe having an uneven cross-section for an improved micro pile structure are provided to improve the structural rigidity of the pile structure because the outer protrusions of the pipe enhance the anchoring force. CONSTITUTION: An installation method of improved micro piles is as follows. The ground is drilled and a casing is installed in the bore. A pipe(30) having an uneven cross-section is inserted in the casing. A pile(40) is inserted in the pipe and grouted. The casing is pulled out. A bracket(60) is installed on the top of the pile and foundation concrete(70) is placed.
