CONCRETE PLACEMENT SYSTEM, CONCRETE PLACEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a concrete placement system capable of suitably placing concrete underwater.SOLUTION: The concrete placement system 1 includes: a concrete transferring pump 7; piping for concrete placement 9; shutter valves 21, 23; a pressure measurement unit 27; a computer 32; display devices 33, 35; a lifting device 37; and a GPS antenna 37b. The piping for concrete placement 9 is a pipeline with one end connected to the concrete transferring pump 7 and the other extending underwater. The piping for concrete placement 9 includes: a water-surface piping part 9a; a flexible piping part 9b; and an underwater piping part 9c. The flexible piping part 9b floats above the water and can move freely by operation of the lifting device 37. The pressure measurement unit 27 measures pressure in the piping immediately before the flexible piping part 9b.
