<P>PROBLEM TO BE SOLVED: To place concrete for connecting a caisson and a pile head extremely quickly immediately after caisson installation by an inexpensive construction method. <P>SOLUTION: By housing a pile head 2a of a foundation pile 2 projected on installation ground G inside a recessed part 11 opened on a lower surface 1a of a caisson 1 while lowering the caisson 1, the caisson 1 is installed on the foundation pile 2. Also, a lath net mold form 4 provided along the inner periphery of the recessed part 11 is lowered and grounded onto the installation ground G, and thereafter, by filling concrete 3 inside the recessed part 11 and inside the lath net mold form 4, the caisson 1 and the foundation pile 2 are integrated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
