Abstract

PURPOSE:To increase the supporting power of a pile, by a mithod wherein, incase a hollow existing pile is driven, the pile is pushed in as it is spinned, the lower end part of the pile is excavated through advance and expansion of an expanding head, and a foot protecting agent is implanted to form a bulb. CONSTITUTION:In a condition that an expanding head is housed in a hollow of a pile 1,the pile 1 is pushed in a ground as it is turned. After it is pushed to a given depth, the expanding head 3 is advanced to a spot below the pile 1 for expansion to dig a hole wherein bulb is formed. A foot protecting agent as cement milk is jetted through a nozzle 4, and the expanding head 3 is raised and moved backward gradually to form a bulb 6. Like this, the pile is pushed as it is turned, and thereby the pile is easily inserted. A ground at the lower end of the pile is not excavated previously, and thereby a horizontal force increases. Additionally, the expanding head is spread in a wider size than the outer diameter of the pile to form the bulb, which results in increasing a supporting power.
