を行なうことができる。The operation of the embankment compaction device having such a configuration will be described. First, the operation of the tamper 11 is started, and vibration is applied to the embankment 10 with a predetermined vibrating force.
Activate 12 to pull tamper 11. Further, the controller is switched on to start the operation. As a result, the tamper 11 is embanked while being pulled by the carrier 12 at a predetermined speed.
While the compacting operation of the embankment 10 is performed, the state of the embankment 10 at the position corresponding to the underground accelerometer 14 is detected by the first acceleration sensor 15 by the operation of the controller. The detection signal from the first acceleration sensor 15 is subjected to analog / digital conversion in the signal converter 16 and sent to the control circuit 17. The control circuit 17 analyzes the compaction condition of the embankment 10 based on the digitized detection data, determines the moving speed of the tamper 11 at which the compaction is best performed for the compacted state, and outputs a control signal. Output as The control signal output from the control circuit 17 is input to the traveling speed conversion device 18, which converts the speed of the carrier 12 based on the control signal from the control circuit 17. That is, when the compaction state of the embankment 10 is not yet sufficient and the embankment 10 is loose, a control signal for decreasing the speed of the carrier 12 is output from the control circuit 17, and the traveling speed conversion is performed based on the control signal. The device 18 reduces the speed of the carrier 12 and moves the tamper 11 slowly. Therefore embankment
The 10 will be slowly compacted over time, resulting in sufficient compaction. As the tamper 11 is pulled by the carrier 12 and moves in the direction of the arrow S, the second acceleration sensor reaches a position corresponding to the soil accelerometer 14, and the control of the control circuit 17 is performed by the second acceleration sensor 19. The state of compaction of the embankment 10 below is detected. As described above, first, the state of the embankment is detected by the first acceleration sensor 15, and the embankment is compacted while changing the moving speed of the tamper 11 based on the detection result. In order to detect the hardened state, the detected waveform over a relatively long time period (4 to 6 seconds) having the waveform peak values (a) and (b) as shown in FIG. As shown in FIG. 4 (b), the compacting operation of the embankment 10 can be performed with higher precision as compared with the conventional detected waveform (c).

高精度な盛土の締固め制御を行なうことができる。When a controller having a configuration as shown in FIG. 3 is used, the detection signal obtained by the first acceleration sensor 15 is subjected to analog / digital conversion by the signal converter 16 and then sent to the control circuit 17. Based on this, the control circuit 17 sends a predetermined control signal to the vibrating force converter 20 to adjust the vibrating force of the tamper 11. As a result, the vibrating force converter 20 changes the vibrating force of the tamper 11 and squeezes the embankment 10 with the controlled vibrating force. The compacted result is detected by the second acceleration sensor 19, and final confirmation of compaction of the embankment 10 is performed.
Also in this case, as shown in FIG. 3, the detection result by the first acceleration sensor and the detection result by the second acceleration sensor 19 have peak values (a), (a) as shown in FIG. As a result, the waveform can be obtained for a relatively long time, and the compaction of the embankment can be performed with higher accuracy than the conventional example in which only the peak value over a short time period can be obtained as shown in FIG. Control can be performed.
