Definitions

  • the invention relates to a method and a device for determining the degree of compaction for soil compaction using a plate vibrator or a Roller, consisting of a superstructure and a vibrating substructure, which with a certain excitation frequency is driven.
  • the present invention is based on the object System to determine the degree of compaction, not only for Rollers, but is also suitable for plate vibrators, the occurring in the latter, withstands high acceleration values and especially through relative low manufacturing costs.
  • At least one amplitude value the vibration of the substructure occurring at the excitation frequency relative for the superstructure it is determined that at least one amplitude value is at least next to it a vibration occurring at a maximum of 60% of the excitation frequency the substructure is determined relative to the superstructure and that finally the quotient from the aforementioned amplitude values as a measure of the current degree of compression of the soil is used.
  • the great advantage of the system according to the invention is that there are no absolute values need to be measured, but only the relative movements between superstructure and substructure. These vibration amplitudes can be contactless, especially inductive, from the superstructure. It needs no sensor can be attached to the vibrating mass and problematic cable connections to the vibrating mass. Another advantage is there in that the separation of the amplitudes is relative depending on their frequency is inexpensively possible electronically.
  • the solution according to the invention is therefore characterized by a comparatively simple one and inexpensive construction and high reliability.
  • Frequency band can be used in its full width or it will only be one relatively narrow frequency range, for example from 10 Hz to 20 Hz extends, picked out or several narrow frequency ranges from superimposed on the mentioned frequency band.
  • the determined amplitude values and / or those calculated from them should be Quotient are averaged because the signals are strong vary. One reading per second is quite sufficient.
  • the Superstructure a sensor for contactless detection of the relative movements between the superstructure and the substructure - especially a sensor for inductive Measured value acquisition with an opposite measuring surface on the substructure corresponds.
  • This has the advantage that the sensor and its electrical connection not the strong accelerations and decelerations of the vibrating Substructure are exposed.
  • the measuring device is therefore characterized by high Reliability and service life and is particularly predestined for plate vibrators.
  • a high-pass filter and a are preferably used to separate the frequency components
  • Band pass filter is used, the high pass filter being approximately the amplitude value at vibration frequency, the bandpass filter the Amplitude value of those occurring at a maximum of 60% of the excitation frequency Vibration separated.
  • the bandpass filter preferably omits amplitude values a frequency range from about 1% to about 50% of the excitation frequency, in In practice, for example, from 1 Hz to 30 Hz happen when the excitation frequency is at 60 Hz.
  • this bandpass filter can also be combined with a highpass filter Cut-off frequency 1 Hz and a low-pass filter with 30 Hz connected in series be replaced.
  • Averaging can be done either directly on the amplitude values or from them formed quotients are used, each with a low pass filter is used, the cut-off frequency is about 0.2 Hz to 1 Hz.
  • Figure 1 shows a plate vibrator known in principle consisting of a superstructure 1 and a vibrating plate 2.
  • the superstructure 1 are in the usual way
  • Drive motor 1a housed with its accessories; he also carries a guide bracket 1b, so that the operator operate the plate vibrator and in the can control the desired direction.
  • a display device 1c At the upper end of this guide bracket 1b is next to the usual controls for switching on and off, and if necessary to change the frequency, a display device 1c for the degree of compaction.
  • the vibration plate 2 is resiliently connected to the superstructure 1 and is by Eccentric waves vibrated with a certain excitation frequency.
  • the enlargement of the section according to FIG. 3 illustrates the measuring principle: in addition the superstructure 1 bears, suitably its rigid machine frame, on the underside a sensor 3 with an opposite measuring surface 4 on the top the vibrating plate cooperates.
  • This sensor is in the embodiment as Travel sensor trained. It is equally within the scope of the invention not the vibration path, but instead the vibration speed, the vibration acceleration or another for the relative movement of the Slab to use characteristic value compared to the superstructure. Preferably is measured in the vertical direction; the measuring direction can also be inclined his.
  • the measurement is expediently carried out inductively; but they are also optical or others Suitable measuring method. Basically, however, should be on the vibrating plate no electrical connection may be necessary.
  • the measurement signal is evaluated via the circuit diagram according to FIG. 3. Accordingly, the displacement signal detected by sensor 3 first passes through a transducer and an amplifier, whereupon the signals are separated into different frequency ranges. The vibrations are selected in the high-pass filter, which take place at the excitation frequency of the plate vibrator. If, for example, a normal vibrator frequency of 60 Hz is assumed, the cut-off frequency f 3 of the high-pass filter is set to just under 60 Hz. Instead, it would also be possible to measure the excitation frequency and to track the high-pass filter according to the actually measured excitation frequency.
  • a bandpass filter which measures the amplitudes, is connected in parallel with the highpass filter from a relatively broad frequency spectrum from about 1% to about 50% of the excitation frequency, here from about 1 Hz to about 30 Hz.
  • the amplitudes of the signals thus separated according to their frequencies are then determined by z. B. amount formation by diode bridge circuit, squaring or peak value measurement is carried out. Then the bandpass filter incoming signals divided by the high-pass filtered signals. This one more strongly scattering quotient then passes through a low pass filter that is so low Cutoff frequency is set that there are no sudden jumps from the display 1c readable value occur.
  • Figures 4 to 6 show the corresponding waveforms, namely Figure 4 den Course of the measurement signal before frequency division, Figure 5, the bandpass filtered Signal, i.e. the amplitudes belonging to the vibrations from 1 Hz to 29 Hz and FIG. 6 shows the high-pass filtered amplitudes that add up to the oscillation Belong to 52 Hz.
  • the quotient Q - i.e. bandpass-filtered signals divided by high-pass filtered Signals - is between 0.2 and 2.0, for example. Its course over the number the transitions are shown in FIG. 7. It corresponds qualitatively to those known per se Curves as previously determined by other measurement methods were and shows the operator - if necessary supported by a acoustic signal - from when there will be further transitions with the compactor no longer worth it.
  • the advantage of the invention is low and inexpensive a reliable determination of the degree of compaction for rollers or plate vibrators.
