PROBLEM TO BE SOLVED: To prevent the occurrence of inconvenience in an unfilled part and a rock pocket in a proper compaction interval range, by executing sure compaction work in a vacant part of a reinforcement such as an overcrowded bar arrangement part.SOLUTION: The present invention compacts concrete by inserting an eccentric weight stored in a vibration cylinder and set in a range of 0.007-0.010 N m, into the concrete by eccentrically rotating at a rotating speed of 150-200 Hz, and thereby, can efficiently compact the concrete of a small vacancy part of the reinforcement. |
