Definitions

  • the present invention relates to a method for planning and implementing soil compaction processes, in particular for asphalt compaction, by means of at least one soil compactor.
  • the US 2010/0087992 A1 discloses a method of compaction of a soil in which, during the performance of a compaction operation, the position of a soil compacter and the reaction of the soil to the compaction process are detected. Based on the information about in which previously compressed area the compression result does not match the compression result in other areas, the soil compactor is controlled to continue the compression operation.
  • the DE 694 16 006 T2 discloses a method of compaction of a subsurface in which the degree of compaction of the soil determined in the course of a compaction process is compared with a predetermined compaction degree and based on the result of the comparison, a soil compactor is controlled to achieve the desired compaction result.
  • this is already planned before carrying out a soil compaction process with regard to the relevant aspects and then carried out according to this plan, ie the compaction plan.
  • This ensures that no unnecessarily large number of compressor crossings is performed, which on the one hand reduce the efficiency of the entire machining process, but on the other hand also bring about the problem of undefined compaction of the soil.
  • the previous planning can be precisely determined where one or more soil compactors as often has to be moved over the soil area to be compacted in order to achieve the desired goal, namely a certain degree of compaction, which should be as constant as possible over the area to be compacted.
  • the measure a) further comprises determining at least one soil compactor to be used for compacting the soil area, and that in the measure b) the compaction plan is further defined based on the at least one compaction compactor to be compacted. Taking into account the soil compactor to be used in the preparation of the compaction plan, it can be ensured that a desired degree of compaction can be achieved as quickly as possible or as precisely as possible.
  • crabability describes whether or to what extent two compressor rollers of a soil compactor can be offset from each other transversely to the direction of travel of this soil compactor so that there is a region in which the two compressor rollers overlap and one for each roller Area exists, with which this laterally beyond the other roller protrudes.
  • the width edge areas of the floor area or at least one of these width edge areas or the course thereof are of particular importance.
  • such a width edge region can form the starting basis in determining the course of soil compactor crossings.
  • At least one width edge region of the bottom region to be compacted is determined by a device moving along the area of the soil to be compacted and preparing it, preferably an asphalt paver.
  • a device preparing the ground area for example an asphalt paver to be compacted, moves precisely in that area in which a soil compactor is subsequently to be moved when carrying out a compaction process. With the movement of this device, so for example asphalt paver, it is thus easily possible to determine the course of at least one Boothnrand Schemes and use for the subsequent creation of the compaction plan.
  • the floor area to be compacted can be defined with regard to its floor area width, so that ultimately it can be determined how many adjacent floor compactor crossings are required at least or at most in order to be able to detect the floor area to be compacted completely or almost completely and sufficiently often. It goes without saying that the soil area to be compacted can also be determined in particular with regard to the material to be compacted, ie, for example, asphalt or the like, as well as its stratification or with regard to the degree of compaction desired when carrying out the soil compaction process.
  • the compaction plan with at least one group of soil compactor crossings is defined, wherein at least one group of soil compactor crossings includes a plurality of soil compactor crossings adjacent to soil region width direction and wherein at least two, preferably all immediately adjacent floor area crossings have overlapping crossing lanes.
  • the overlap between immediately adjacent crossing lanes taking into account that there is an unavoidable inaccuracy or blurring with respect to the surface area actually traveled during the advancement of a soil compactor, ensures that in fact every area can also be detected.
  • the overlap is advantageously to be selected such that it is at least as large, advantageously larger, than the unavoidable blurring with respect to the actually detected surface areas when advancing a soil compactor.
  • a bottom area to be compacted is bounded by at least one width edge area
  • at least one group of ground compactor crossings has at least one crossing track substantially flush along a width edge area of the floor area to be compacted to be led.
  • substantially flush should be used here to state that the guided track along the width edge region lies in such a way that substantially no surface area remains in the width edge region in which the material to be compacted is not detected during a soil compactor crossing, but nevertheless avoided is that a soil compactor with his or her compressor rollers unnecessarily far beyond the width edge region beyond in an area in which no soil material to be compressed is no longer present.
  • the or at least a portion of, preferably all of the lane lanes of at least one group of soil compactor crossings, preferably substantially all groups of soil compactor crossings, may be guided to extend substantially in the direction of a bottom region longitudinal direction, which may be substantially orthogonal to the bottom region width direction, for example.
  • the guided overpass track can protrude laterally beyond the width edge region, in which case the size BB is to be added with the overall extent of the protrusion existing in the two edge regions.
  • the then existing or available overlap extent of the individual crossing lanes is less than in the case in which there is no projection in one or possibly both width edge areas.
  • At least one soil compactor passage may be defined to include a movement of at least one soil compactor to compress the soil area in a first direction of travel and a second direction of movement opposite the first direction of movement.
  • Fig. 1 is shown in a schematic representation and in side view generally denoted by 10 soil compactor, which runs on a bottom region B to be compacted to compact the compacted soil material M of the bottom portion B in one or more soil compactors crossings.
  • This material B may be, for example, in road construction asphalt material which is applied with a paving machine in one or more layers in the flowable state and is compacted before the complete hardening by or possibly more soil compactor 10.
  • the soil compactor 10 comprises two compressor rollers 12, 14, generally also referred to as bandages.
  • the compressor roller 12 is rotatably supported on a front compressor frame 16 and, if necessary, also driven for rotation.
  • the compressor roller 14 is rotatable on a rear compressor frame 18 and possibly also driven for rotation driven.
  • the front frame 16 and the rear frame 18 are pivotally supported on a central frame 20 about respective vertical axes A 1 and A 2 by a pivot drive, not shown.
  • this allows the directional control and, on the other hand, allows the setting of a so-called crab gear.
  • the front roller 12 and the rear roller 14 in the lateral direction, ie in the illustration of Fig.
  • the surface area of the bottom area to be compacted during the advancement of the soil compactor 10 is increased, with a partial area of this detected area being crossed by both compressor rollers 12, 14, while on both sides there are subareas which only from one of the two compressor rollers 12 , 14 are detected or overrun.
  • this adjustability of the crab also by different design of the soil compactor can be achieved.
  • the entire compressor frame can be rigid in itself and the pivotability of the two compressor rollers 12, 14 about respective vertical pivot axes can be realized where the rollers are connected to the rigid rigid compressor frame supporting.
  • a generally designated 22 cab with seating 24 and a display 26 is provided on the central compressor frame 20 .
  • the display 26 the occupant seated on the seat 24 can be represented for a compaction process to be performed relevant information.
  • the soil compactor 10 may receive or transmit information from a central station or other soil compactor.
  • the radio unit 28 may also be designed as a GPS unit in order to be able to obtain information about the positioning of the soil compactor 10 in space in this manner.
  • soil compactors in carrying out a compression process differently constructed soil compactors can be used. For example, these can be designed without the possibility of crabbing.
  • the soil compactors may also differ in the number of compressor rollers present, and when a soil compactor has only one compactor roller, it may further generally have wheels used for propulsion at the rear frame portion.
  • the soil compactors may continue to differ in the width of one or more of the existing compressor rolls, as well as in the weight of the compressor or the weight distribution on the two existing rollers.
  • Such soil compactors may further differ is the compaction modes that can be performed therewith. These include various physical aspects with which in addition to the surface load occurring due to the weight load, the compression result achieved in a soil compactor passage can be influenced or adjusted.
  • a compression mode may, for example, be a vibration mode in which, by a vibration mechanism provided in a respective compressor roller, the compressor roller is driven to vibrate substantially in the vertical direction.
  • Another compression mode may include an oscillation operation in which a compressor roller is driven by an oscillating drive to vibrate circumferentially about its roller rotational axis.
  • these different operating modes can also differ in the respective oscillation frequency or oscillation amplitude.
  • the compression modes may also include a static compression mode, that is, driving over with one or more compressor rolls without the additional generation of vibrational motions.
  • GPS Global Positioning System
  • the term GPS here represents a plurality of different, generally satellite-based operating systems, which offer the possibility in real time positioning of a unit equipped with such a unit, so for example a soil compactor or an asphalt paver or the like, and accordingly to provide this positioning or the movement history representing data or such data z. B. to use for controlling the Voranterrorism.
  • the driving over with one or more compressor rollers or alternatively or additionally one or more rubber wheels can be considered as each differentiating compression mode. In this case, it is also possible in particular to interpret a plurality of rubber wheels combined in groups and optionally also offset or overlapping one another in their entirety as one or more compressor rollers.
  • the soil area B to be compacted is first defined with regard to various parameters.
  • An essential parameter is the floor area width BB.
  • the bottom area length BL plays a substantial role in particular in the compaction of asphalt material, since it is an essential factor determining the area of the floor area to be compacted and it has to be taken into account that the compaction process has to be substantially completed before the material to be compacted is due to, for example Cooling has reached a state in which a further compression is practically unreachable.
  • the structure of the material M to be compacted will generally also have to be taken into account or the desired result after the compression process has been carried out.
  • an asphalt model can be created in a manner known per se, in which the degree of compaction desired, taking account of the asphalt stratification, is determined.
  • the selection of one or more soil compactors to be used can then be made from a group of soil compactors which differ in at least one of the parameters mentioned above and specifying them.
  • selecting several soil compactors from the group can of course also identical soil compactors be used.
  • the Fig. 3 shows a schematic representation of the compacted to bottom region B, which has the two in the Boden Schemeslteilscardi R L extending width edge regions BR 1 and BR 2 , for example, the edge regions of a road to be created. Between these two width edge regions BR 1 and BR 2 , the bottom region B extends with its bottom region width BB, wherein a bottom region width direction R B, for example, is substantially orthogonal to the bottom region longitudinal direction R L.
  • the course of the bottom region B to be compacted in the bottom region longitudinal direction R L is, above all, the Fig. 2 shows, basically determined by the course of the two width edge regions BR 1 and BR 2 . It may therefore be advantageous for the preparation of the compaction plan in the manner described below, first these width edge areas BR 1 and BR 2 in terms of their course and also their respective end in the Boden Schemesllindsraum R L to define. This can be done, for example, based on map data generated by surveying work, in which the course of the ground area to be compacted, for example, a road to be created, is reproduced.
  • the progression of the width edge regions BR 1 and BR 2 or the course of at least one of these two width edge regions BR 1 and BR 2 is determined in a work step preceding a compaction process.
  • a device is used, which moves in such a preceding step in the later to be compacted bottom area B.
  • an asphalt paver may be used which, in the soil area B to be compacted below, produces asphalt material.
  • the associated width edge area BR 1 and BR 2 detecting GPS units be provided so that in a Voranschulsvorgang both width edge regions BR 1 , BR 2 detected or their spatial position defining data can be determined and provided for the preparation of the compaction plan.
  • the floor area B is so wide that a previous processing is not possible with a single device, so for example a single asphalt paver, for example, several such pavers can side by side and in the direction of production slightly offset from each other to each other directly adjacent to several asphalt layers to deploy, which then define in their entirety the bottom area B to be compacted. It is then possible for the two lateral edge regions BR 1 , BR 2 to be provided on the various devices moving along the respective width edge regions when the asphalt pavers are advancing.
  • floor area B when preparing to be compacted floor area B with multiple devices, so for example asphalt pavers, prepared by all these devices together floor area can be used in its entirety as the then to be compacted floor area B to the compaction plan then especially using this entire area to create limiting width border areas.
  • a first group G 1 of ground area crossings BVÜ can be defined.
  • Each Boden Schemesüberfahrt BVÜ is assigned an overpass track ÜS, along which at a respective compactor crossing BVÜ, for example, the in Fig. 1 shown soil compactor 10 moves.
  • the floor area compressor 10 moves back once in a first direction of movement R 1 and once in an opposite second direction of movement R 2 .
  • the soil compactor 10 therefore moves twice along the designated overpass lane ÜS at each soil compactor crossing BVÜ, which, when using the in-transit track ÜS Fig. 1
  • the surface area detected by a respective over-travel track ÜS is passed over four times by one compacting roller, namely twice by the compacting roller 12 and twice by the compacting roller 14.

  • each crossing track ÜS corresponds in its width to the compressor roller area VWB of the compressor rollers 12 and 14, which move beyond the floor area B.
  • a crossing lane ÜS 1a or ÜS 1d is guided along a respective width edge region BR 1 or BR 2 .
  • a respective side edge of the compressor roller 12 or 14 may be guided such that it is guided approximately exactly along the width edge region BR 1 or BR 2 .
  • a certain projection can also be provided in order to ensure that, taking into account the unavoidable unevenness in the movement of the soil compactor 10, no surface area arises in which At a respective width edge region BR 1 or BR 2, the material M can not or can not be compacted sufficiently.
