PROBLEM TO BE SOLVED: To provide an objective and highly reliable compaction control device and method for enabling information including a time from the delivery of concrete to compaction thereof and the insertion depth of a vibrator to be all stored as records and networked after collected by a field office.SOLUTION: A device installed on a concrete plant 3 inputs and transmits data of concrete. A device installed on a site field office 1 can input and record the data from the plant 3, and record advance testing data and compare it with the data from the plant 3. A device mounted on a concrete transportation vehicle 4 can input, record and display the data from the plant 3. A depth indicator mounted on the compaction device can detect the depth of the vibrator inserted into the concrete. A device installed on the operation part of the compaction device can receive a signal from the field office 1 and give vibration to the concrete at an insertion depth and for a duration, as instructed. |
