PRECAST PILE HOLDING DEVICE AND FOUNDATION PILE CONSTRUCTION METHOD
To provide a precast pile holding device capable of reliably holding a precast pile at a predetermined depth in a pre-boring method and a foundation pile construction method using the same.SOLUTION: A precast pile holding device sunk in a pile hole comprises a pile engagement portion that can be engaged with precast piles, a shaft portion connected to the pile engagement portion, a fixture that can be externally fitted to the shaft portion, a girder member arranged so as to cross the pile hole, and a height adjuster placed between the fixture and the girder member. The shaft portion is provided with a plurality of concave portions separated from each other in the axial direction of the shaft portion. A convex portion provided on the fixture or the engagement pin inserted through the fixture can be selectively engaged with any of the plurality of concave portions.SELECTED DRAWING: Figure 4
【課題】プレボーリング工法において既製杭を所定深さに確実に保持可能な既製杭の保持装置及びそれを用いた基礎杭構築方法を提供する。【解決手段】杭穴に沈設された既製杭の保持装置は、既製杭に係合可能な杭係合部と、杭係合部に連なる軸部と、軸部に外嵌可能な固定具と、杭穴を横断するように配置される桁部材と、固定具と桁部材との間に配置される高さ調整具と、を備える。軸部には軸部の軸線方向に離間して複数の凹部が設けられ、固定具に設けられた凸部又は固定具に挿通される係合ピンを複数の凹部の何れかと選択的に係合可能である。【選択図】図４
