Definitions

  • the invention relates to a method for compacting a floor area and / or a flooring applied to a floor area according to claim 1, a device with at least one unbalance unit for compacting according to claim 8 and a device arrangement, which u.a. several devices according to claim 13 or 14th
  • the device was operated in intimate contact with the ground. Soil and device formed a single vibration system. To determine the relative values, the device was moved jumping over the ground surface and in this case the amplitude values and frequencies of the subharmonic frequency values forming at the excitation frequency were evaluated. The absolute measurement was a measurement in one place while the relative measurement was made during the overrun. Since the relative measurements could be converted into absolute values via the absolute measurement, it was thus possible to convert a relative soil stiffness determined during a compact overrun into an absolute value of the soil stiffness. The values determined in this case were displayed to the vehicle driver of the compacting device, who then had to decide on the further compaction procedure.
  • the compacting control is used in blackcaps in road construction to generate and record a first compaction measured value generated by a first compaction device and to compare it to a second compaction value generated by a second compaction device, the second compaction value being determined at approximately the same asphalt temperature is. Measures were taken that the second compacting device was coupled with the first substantially tracking.
  • the compacting vibratory rollers could also be provided in two separate compactors. The two compactors were then coupled together via a computer-aided tracking system. With the computer-assisted tracking method, a Global Positioning System (GPS) could be used. The two compactors could also be coupled with each other via radar, ultrasound or infrared.
  • GPS Global Positioning System
  • the degree of compaction achieved was concluded by measuring vibration reflections during the compaction process. If, in spite of the increasing number of compression transitions, the compression no longer changed in the compression control device, the highest density achievable with a specific compacting device was achieved. The achieved compaction values were displayed on a display unit to the roller guide.
  • the object of the invention is to provide a method or to provide a corresponding device, with or with which an optimal soil compaction in an optimal time frame can be achieved.
  • Advantage of the invention is the relief of the person (eg roller guide), which has to perform the compaction device.
  • the machine settings (overrun, overspeed and compressor values) are made automatically for optimal, time-reduced compression, the leader of the compacting device can now concentrate fully on guiding the compacting device and the safety conditions to be observed.
  • a subsequent "shaking up" of floor areas by not necessary further driving over is excluded.
  • Another driving over, which is necessary, for example, to reach areas still to be compressed can now be carried out in such a way that no "shaking up” occurs.
  • a combination of a plurality of compacting devices which moreover can also have different force devices for a compaction to be carried out.
  • the compressor values are understood in particular to be an adjustable floor reaction force F B and a phase angle ⁇ .
  • the phase angle ⁇ is an angle between the maximum floor reaction force F B directed perpendicularly to the surface of the floor area and a maximum vibration value of a vibration response of a vibration system. As described below, this vibration system is formed from the bottom portion and the compression unit vibrating unit.
  • unbalances with an imbalance torque and an imbalance frequency are used for compaction. Since, in the invention, the compressor values are set automatically by a regulated setting device, the unbalance torque and imbalance frequency are controlled analogously, d, h. set determined by a computing unit.
  • unbalance moment and imbalance frequency are adjusted in such a way with a setting unit that, according to theoretical calculations, a predetermined compaction setpoint of a floor area or a floor covering area is achieved.
  • the compaction setpoint will always be the same over long distances, but it does not have to be the same Unbalance torque and imbalance frequency are automatically adjustable.
  • the soil compaction achieved is immediately determined when passing over, and the determined actual compaction value is stored together with the location coordinates of the area for a later treatment.
  • compressor values is understood to mean the compression-causing movements of the compacting device.
  • reaction is in each case based on the soil or lining to be compacted or compacted.
  • This subsequent treatment can now be a renewed compacting overrun or even a treatment of the soil area, if it turns out by the repeated location-related compaction measurements that this soil area not further, for example due to its material composition, the substrate, etc., is compressible.
  • the impossibility of further compression can be determined by the fact that the achieved Verdichtungsistute are determined and stored locally related to each compression process. These stored values are compared. If no (significant) increase in compaction is detected, then just this area is not further compressible. In order to avoid damaging or wasting time in this area due to further compaction processes, imbalance torque and unbalance frequency can be set in this area in such a way that only a surface-smoothing override takes place.
  • Unbalance torque and imbalance frequency are also set for smoothing over the surface if an area is already compressed to the required compression value and adjacent areas or areas in a given travel route have not yet reached this value.
  • the compacting device according to the invention is a "compacting machine".
  • the leader of the compaction device is then informed by the arithmetic unit, which processes the location-related compression actual values from the memory unit, proposes a route.
  • the proposal of a guideway can be displayed on a display unit arranged in the driver's cab.
  • the track can also be mirrored on the so-called windshield or directly with a light beam, in particular by means of a laser beam (eg a red Heliumneonlaserstrahl) are displayed on the floor areas.
  • a laser beam eg a red Heliumneonlaserstrahl
  • each compaction device knows its specific compaction characteristics and can set accordingly from the predetermined compaction setpoints with an adjustment unit unbalance moment and imbalance frequency.
  • the timer knows the machine-typical setting time and thus knows at a given speed of movement (usually traversing speed), in which period of time must be started with the adjustment so that the determined unbalance and the determined imbalance frequency come into play when reaching the area concerned.
  • each compacting device When using a plurality of compacting devices, it is no longer sufficient to store the predetermined area-specific compaction setpoint, to determine the location allocation with a triangulation system or GPS and to store the ascertained actual density values (area-specifically) so that they can be considered in a new compaction process. If more than one compacting device is present, it is generally driven in columns, so that one and the same compacting device does not always travel over areas that are pre-compressed by it. In this case, it is preferable to transmit the actual compression values via transmission and reception equipment from device to device. Preferably, then each compacting device has a system for exact location determination.
  • the area-specific compaction setpoint values can then be transmitted to the compaction devices from this center.

  • the obtained values are substituted into the equation ⁇ B ⁇ using for s the soil stiffness values k B1 , k B2 , k B3 and k B4 .
  • weighting values for different soil compositions can be stored in a memory of the device (typically, however, in a central unit listed below) and measurements made within a tolerance dictated by a soil composition.
  • calibration should always be performed on changing soil compositions to obtain sufficient accuracy. Although a calibration is significantly slower than the rapid relative measurement; however, with a little practice, a calibration can be done in a few minutes.

  • phase curves also referred to as orbitals
  • orbitals are closed circles or ellipses in the case of linear, stationary and monofrequent oscillations.
  • additional harmonics occur (periodic lifting of the bandage from the ground)
  • the harmonics can be recognized as modulated periodicities. Only at period doublings, ie subharmonic oscillations such as "jumping", does the original circle mutate into closed curves that have intersections in the phase space representation.
  • a measurement can be triggered in practice by the pulse of a Hall probe, which detects the zero crossing of the vibro wave. This can also generate Poincaré images. If the periodically recorded amplitude values are plotted as a function of the varied system parameter, in our case the ground stiffness k B , then the bifurcation or so-called fig tree diagram arises (FIG. 5). In this diagram, on the one hand, one recognizes the property of the amplitudes suddenly increasing as the rigidity increases in the region of the branch, and the tangent to the associated curve (s) runs vertically at the branching point. Therefore, in practice, no additional energy supply for the jumping of the roller is required.
  • the diagram further shows that with increasing stiffness (compression) further branches follow, and in ever shorter intervals with respect to the continuously increasing stiffness k B.
  • the branches produce a cascade of new vibrational components with each half the frequency of the previous lowest frequency of the spectrum.

Analogous to the fundamental, the subharmonic harmonics also generate it creates a frequency continuum in the low-frequency range of the signal spectrum. This is also a specific property of the chaotic system, in this case the vibrating vibrating plate.
  • the system of the compactor is in a deterministic rather than a stochastic chaotic state. Since the parameters that cause the chaotic state are not all measurable (not fully observable), the operating state of the subharmonic vibrations can not be predicted for practical compaction.
  • the operating behavior in practice is also characterized by many imponderables, the machine can slip away due to the strong contact loss to the ground, the load on the machine by the low-frequency Vibrations get very high. Ongoing further bifurcations of the machine behavior (unexpected) can occur, which immediately result in heavy additional loads. High stresses also occur between the bandage and the floor; This leads to the undesirable loosening of near-surface layers and causes grain breakup.
