CONSTRUCTION METHOD FOR FOUNDATION PILE WITH REINFORCED PILE HEAD
PROBLEM TO BE SOLVED: To provide a method for reinforcing a pile head of a foundation pile capable of effectively reinforcing a pile head of a foundation pile without requiring a heavy machine in addition to a pile driver and without generating excavation surplus soil.SOLUTION: The method includes the steps of: penetrating a cylindrical casing 60 which has a removable bottom cover 63 and an inner diameter larger than an outer diameter of a foundation pile body 10 to a predetermined pile head reinforcement depth of a foundation pile and securing a space part 60a inside of the casing; removing the bottom cover from the casing, inserting the foundation pile body into the space part of the casing, and penetrating the foundation pile to a support foundation; inserting a reinforcing-bar basket 20 into an annular space 70 that is formed between the casing and the foundation pile body, and installing concrete 30 as a flowable solidification material; and pulling out the casing.SELECTED DRAWING: Figure 1
【課題】杭打機とは別の重機を必要とせず、掘削残土が発生せず、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こと。【解決手段】着脱可能な底蓋６３を有し、内径が基礎杭本体１０の外径よりも大きい円筒状のケーシング６０を基礎杭の杭頭部補強予定深度まで貫入させてケーシングの内部に空間部６０ａを確保する工程と、底蓋をケーシングから取り外し、ケーシングの空間部に基礎杭本体を挿入して支持地盤まで貫入させる工程と、ケーシングと基礎杭本体との間に形成された円環状空間７０に鉄筋籠２０を挿入して流動性固化材としてのコンクリート３０を打設する工程と、ケーシングを引き抜く工程と、を備える。【選択図】図１
