CONSTRUCTION METHOD OF COLUMNAR IMPROVEMENT BODY WITH CORE MATERIAL AND COLUMNAR IMPROVEMENT BODY WITH CORE MATERIAL
To reduce positional deviation of rod-like steel materials against a columnar improvement body.SOLUTION: A construction method of a columnar improvement body with core material includes a drop-in process in which wall-shaped bars 20 each having multiple bar-shaped steel members 22 connected by wavy shear reinforcing bars 24 are arranged on both sides of a web 34, and H-shaped steel 30 to which the upper parts of the bar-shaped steel members 22 are attached is dropped into a columnar improvement body 10 before hardening while being vibrated, and a lifting process of lifting the H-shaped steel 30 from the unhardened columnar improvement body 10 in a state in which the upper parts of the bar-shaped steel members 22 are removed from the H-shaped steel 30.SELECTED DRAWING: Figure 5
【課題】柱状改良体に対する棒状鋼材の位置ずれを低減することを目的とする。【解決手段】芯材付き柱状改良体の施工方法は、複数の棒状鋼材２２を波形せん断補強筋２４で連結した壁状筋２０がウェブ３４の両側にそれぞれ配置されるとともに、棒状鋼材２２の上部が取り付けられたＨ形鋼３０を加振しながら硬化前の柱状改良体１０に落とし込む落とし込み工程と、Ｈ形鋼３０から棒状鋼材２２の上部を取り外した状態で、硬化前の柱状改良体１０からＨ形鋼３０を引き上げる引き上げ工程と、を備える。【選択図】図５
