Then, the concrete in the lifting bucket 120 is put into the storage bucket 110 by opening an opening / closing window of the lifting bucket 120 on the storage bucket 110.

  The concrete stored in the storage bucket 110 is transported to a placement position away from the pilaster portion 2 by the transport bucket 140. First, the concrete in the storage bucket 110 is put into the transport bucket 140 through the hopper 116 and the hose 118 by opening an opening / closing window of the storage bucket 110. And the bucket 140 for conveyance into which concrete was thrown is moved to the placement position by operating the electric trolley 132.

  Then, as shown in FIG. 10, the concrete in the transport bucket 140 is slid down by the concrete chute 106 by opening the opening / closing window 146 of the transport bucket 140 on the concrete chute 106 installed at the placement position. And put it between the molds 11 and 12. Here, the placement of the concrete at a position away from the pilaster part 2 is performed in the order from a position far from the pilaster part 2 to a position close thereto.

  Then, as shown in FIG. 11, the lifting bucket 104 is directly lifted onto the hopper 102 of the placing portion 101 by the crane 3. Then, by opening the opening / closing window of the lifting bucket 104 on the hopper 102, the concrete in the lifting bucket 104 is put into the molds 11 and 12 through the hopper 102, the hose and the concrete chute. Thereby, concrete placement of the pilaster part 2 of the breakwater 1 is implemented.
