REINFORCING-BAR CAGE INSERTION DEVICE AND REINFORCING-BAR CAGE INSERTION METHOD
To provide a reinforcing-bar cage insertion device and a reinforcing-bar cage insertion method which can insert a reinforcing-bar cage into a soil cement column body while keeping an attitude of the reinforcing-bar cage.SOLUTION: Using a reinforcing-bar cage insertion device 10 including a rod material 12 pressed-in an uncured soil cement column body 30 with driving means 22, an annular ring 14 as an engagement member engaged with a tip of the rod material 12, and a guide wire 18 as a plurality of connection members which connect the reinforcing-bar cage 16 configured in a cage shape with a main reinforcement 26 and a hoop 28 and the annular ring 14, and position the annular ring 14 to a position of a shaft center of the reinforcing-bar cage 16, the rod material 12 is pressed in the soil cement column body 30 with the driving means 22, and thereby the reinforcing-bar cage 16 is inserted to the soil cement column body 30, and then only the rod material 12 is pulled out from the soil cement column body 30 after the reinforcing-bar cage 16 is inserted to a predetermined depth of the soil cement column body 30.SELECTED DRAWING: Figure 1
【課題】鉄筋籠の姿勢を保ちつつ、鉄筋籠をソイルセメント柱体に挿入することができる鉄筋籠挿入装置及び鉄筋籠挿入方法を提供する。【解決手段】駆動手段２２によって未硬化のソイルセメント柱体３０に圧入される棒材１２と、棒材１２の先端に係合される係合部材としての環状リング１４と、主筋２６及び帯筋２８によって籠状に構成された鉄筋籠１６と環状リング１４とを連結し、環状リング１４を鉄筋籠１６の軸芯に位置させる複数の連結部材としての誘導ワイヤ１８と、を有する鉄筋籠挿入装置１０を用い、駆動手段２２によって棒材１２をソイルセメント柱体３０に圧入することにより、鉄筋籠１６をソイルセメント柱体３０に挿入し、鉄筋籠１６をソイルセメント柱体３０の所定の深度まで挿入した後で、棒材１２のみをソイルセメント柱体３０から引き抜く。【選択図】図１
