SPRING SPACER, REINFORCEMENT CAGE, AND UNDERGROUND PILE INSTALLATION METHOD
To provide a spring spacer capable of more accurately executing the positioning of a pile of a pile reinforcement cage in a radial direction and holding it, and preventing misalignment of a pile core of an underground pile, a reinforcement cage, and an underground pile installation method.SOLUTION: A spring spacer reinforcement 2 assembled to a reinforcement cage 1 built into an underground pile installed in the foundation comprises: an expansion part 23 that expands from a fastened part 24 with a main reinforcement 11 in the radial direction of the underground pile; and a bent part 22 bent and connected to the expansion part 23. The bent part 22 is bent so as to be parallel to the main reinforcement 11, and its free end 21 side is bent in the center direction of the underground pile.SELECTED DRAWING: Figure 2
【課題】杭鉄筋籠の杭の径方向の位置決めをより的確に行い保持し、地中杭の杭芯にズレが生じるのを防止できるスプリングスペーサー、鉄筋籠及び地中杭の打設工法を提供する。【解決手段】地盤に打設される地中杭中に建込まれる鉄筋籠１に組み付けられるスプリングスペーサー筋２であって、主筋１１との緊結部分２４から地中杭の径方向に拡開する拡開部２３と、拡開部２３に対して屈曲されて接続された屈曲部２２とを有する。屈曲部２２は、主筋１１と平行となるように屈曲され、その自由端２１側が地中杭の中心方向に屈曲されている。【選択図】図２
