<p>PROBLEM TO BE SOLVED: To provide a technology which improves the placing efficiency of invert concrete.SOLUTION: A concrete placing system 10 comprises an invert pier 11, and a placing piping moving device 20 installed at the invert pier 11. The placing piping moving device 20 comprises first and second rails 21, 22, a beam member 25, and a turning support part 30. The beam member 25 can move to an axial direction along the first rail 21 and the second rail 22 by an axially-moving part 40. The beam member 25 is separated to a first beam part 26 and a second beam part 27, and constituted so as to be bendable by the turning support part 30. A first moving motor block 71 and a second moving motor block 72 for suspending a piping hose 80 are movably attached to the beam member 25.</p> |
