PILE HEAD REINFORCEMENT METHOD FOR FOUNDATION PILE
PROBLEM TO BE SOLVED: To provide a pile head reinforcement method for a foundation pile that effectively reinforces a pile head of a foundation pile.SOLUTION: A pile head reinforcement method for a foundation pile uses an excavation tube 10 that includes: a tubular body that forms a space 14 for erecting a reinforcing body 22 containing a cage 21 by casting a curable fluid 20 around a pile head B of a foundation pile A; a blade that may be screwed-in, installed on an outer peripheral surface of the tubular body; and a bottom cover installed detachably on a bottom part of the tubular body for closing the bottom part, having a through-hole through which the pile head penetrates. The pile head reinforcement method comprises the following steps for: rotation and penetration in which the excavation tube is rotated and made to penetrate into a construction ground where the foundation pile has been buried; installing the cage in a space around the pile head; casting the curable fluid into the space around the pile head; and removing the excavation tube from the construction ground, leaving behind the bottom cover.SELECTED DRAWING: Figure 1
【課題】基礎杭の杭頭部を効果的に補強することが可能な基礎杭の杭頭部補強工法を提供する。【解決手段】基礎杭Ａの杭頭部Ｂの周囲に硬化性流動体２０を打設して鉄筋籠２１入りの補強体２２を構築するための空間１４を形成する筒状体と、該筒状体の外周面に設けられたねじ込み作用を有する羽根と、杭頭部が貫通する貫通穴を有して筒状体の底部に着脱自在に取り付けられて該底部を閉じる底蓋とを備える、掘削管１０を使用し、該掘削管を基礎杭が埋設されている施工地盤に回転貫入させる、回転貫入工程と、杭頭部の周囲の空間内に鉄筋籠を設置する設置工程と、杭頭部の周囲の空間内に硬化性流動体を打設する打設工程と、底蓋を残して、掘削管を施工地盤から撤去する撤去工程と、を備える。【選択図】図１
