PURPOSE: To facilitate to insert a pipe through by providing a necessary number of positioning jigs constituted of reinforcement and the like having pipe inserting enclosures in the lengthwise direction inside a reinforcement cage, and inserting guide pipes for compaction piles into the enclosures.
CONSTITUTION: A necessary number of positioning jigs 4 each having a plurality of enclosures 5 are provided inside a reinforcement cage 2 inserted into a drilled hole in the vertical direction. The shape of the positioning jig 4 is different according to the number of guide pipes to be inserted. Next, after providing the reinforcement cage, concrete is poured in from a tremie pipe 6, at the same time rotary type compaction piles are inserted into the guide pipes 1, and compaction of the placed concrete is performed.
