。The enlarged bottom s1 is positioned in the area where the bottom expands, and as shown in FIG. The respective lengths of the upper vertical member 5 and the lower vertical member 7 are set so that the pivot shaft 6 connected to the enlarged bottom portion 1 is located in the region of the maximum inner diameter of the enlarged bottom portion 1. Furthermore, when both vertical members 5 and 7 are expanded outward as shown in Figure 51g2, both vertical members 5 and 7 are arranged so that the upper vertical member 5 extends approximately #1 parallel to the upper inner wall of the enlarged bottom portion 1. The relative lengths of members 5 and 7 are set. Note that 10 and 11 are horizontal in order to maintain the state in which the pair of upper and lower vertical members are spread out in the enlarged bottom part 1 at equal intervals when the upper and lower vertical members are spread outward. This is a chain that is extended and fixed.

にはぼ平行に延在している。First, as shown in FIG. 1, the second movable reinforcing bar 3 constructed as described above is attached to the lower part of the first reinforcing bar cage 2 in a partially overlapping state. Next, the reinforcing bar cage assembly is gradually lowered into the expanded bottom pile, and the lower locking ring 9 of the second reinforcing bar cage 3 is brought into contact with the bottom surface 4 of the expanded bottom pile (the first
(see figure). If the reinforcing bar assembly/pre is further sunk, the lower locking ring 9 will not move, so the upper and lower locking rings 7 and 8
functions as a fulcrum, and the pivot 6 functions as a bending point, so that both the upper and lower vertical members 5 and 7 begin to expand outward, and the lower end of the vertical member of the first reinforcing bar cage 2 reaches the bottom II 4 of the expanded bottom pile. When the upper and lower twill members 5 and 7 come into contact with the
As shown in FIG. 2, each extends substantially parallel to the upper inner wall of the enlarged bottom portion l.

７が容易に外向きに広がることができるようにするため
、下Ｓ係とリング９は第１の鉄筋籠２の径よりかなり小
径に寸法ぎめされていることが好ましい。As can be seen from FIG. 1, the lower locking ring 9 of the second reinforcing bar cage is in contact with the bottom surface 4 of the expanded bottom pile, and both the upper and lower vertical members 5 and 7 can easily expand outward. Therefore, it is preferable that the lower S member and the ring 9 are dimensioned to have a considerably smaller diameter than the diameter of the first reinforcing bar cage 2.
