PROBLEM TO BE SOLVED: To simplify not only setting work of concrete but also compacting work of concrete by providing a control apparatus for performing operations for elevation of a concrete setting cylinder, a divergence adjusting mechanism and advancing and retreating of a vibration part. SOLUTION: Each vibrator 46 is constituted in such a way that a supporting lever 60 is connected to the end part of an operational rod 58 of a pneumatic cylinder 56 stored in a cylindrical casing 54 with a seal structure and this supporting rod 60 is water-tightly formed to the cylindrical casing 54 and in addition, a rod-like high frequency vibration part 64 is arranged on the supporting rod 60 through a vibration-proof cylinder 62. In addition, An electric source feeding cable 66 for a high frequency motor is arranged in the vibration part 64. In addition, each operation for elevation of a concrete setting cylinder 34, divergence of three concrete vibrators 46 and advancing and retreating of the high frequency vibration part 64 can be remotely controlled by means of a controller 70 connected to a control part 68. Therefore, it is possible to facilitate setting and compacting works of concrete. |
