MICRO PILE AND METHOD OF CONSTRUCTING THE SAME

摘要

A micro pile increased in supporting force and horizontal resistance force and a method of constructing the micro pile. The micro pile (10) for connecting a structure (16) to a support layer (14) in the ground comprises a pile body (18) formed of a grout pressurizingly filled in an excavated hole formed in the ground and hardened. The bottom end portion of the pile body (18) is extended in the support layer (14). Steel tube type reinforcement materials (20) and steel bar type reinforcement materials (30) are buried in the grout of the pile body (18) so as to be disposed roughly concentrical to each other and extended in the longitudinal direction of the pile body (18), and the steel bar type reinforcement materials (30) are positioned at the roughly center of the pile body (18). The steel tube type reinforcement materials (20) extend from the upper end of the pile body (18) into the lower end portion of the pile body (18), and the outer peripheral surfaces thereof are covered by the grout of the pile body (18). The steel bar type reinforcement materials (30) extend from the upper end of the pile body (18) to the lower end (18) of the pile body, and the lower end portions thereof extend from the lower ends of the steel tube type reinforcement materials (20) and are covered by the grout of the pile body (18).
