Description

Die Erfindung betrifft eine Vorrichtung zur Aufbereitung von ausgehobenem Erdreich zu einem standfesten Baumaterial.The invention relates to a device for processing excavated soil into a stable construction material.

Es ist bekannt, daß bei der Erstellung von Fahrbahnen der Unterbau aufbereitet werden muß, sofern die notwendige Tragfähigkeit des Bodens nicht gegeben ist. Hierzu wird auf die Bodenfläche eine vorgegebene Menge Kalk aufgebracht und anschließend der Kalk mittels Bodenfräsen oder dgl. Maschinen in die oberste Erdschicht eingearbeitet. Eine derartige dem Ackerbau ähnliche Bearbeitung des Bodens ist auf großen, freien Flächen zufriedenstellend, wenngleich es dennoch zu Beeinträchtigungen durch Kalkstaub und dgl. kommt, sofern entsprechend starker Wind den aufgelegten Kalk aufwirbelt oder an der Arbeitsstelle vorbeifahrender Verkehr zu entsprechenden Luftbewegungen führt.It is known that the substructure must be prepared when creating roadways, provided that the necessary load-bearing capacity of the floor is not given. For this purpose, a predetermined amount of lime is applied to the floor surface and then the lime is worked into the uppermost layer of soil by means of soil milling or similar machines. Such cultivation of the soil, which is similar to arable farming, is satisfactory on large, free areas, although it is nevertheless adversely affected by lime dust and the like, provided that strong lime swirls up the lime on top or that traffic flowing past the workplace leads to corresponding air movements.

Bei der Arbeitsraumverfüllung im Bereich des Kanalisationsbaus muß entsprechend tragfähiges Material verwendet werden. Ausgehobener, nicht tragfähiger Boden wird daher grundsätzlich abgefahren und die Arbeitsraumverfüllung durch andere Materialien wie Schotter, Kies oder dgl. vorgenommen.When filling the work area in the area of the sewage system, suitable load-bearing material must be used. Excavated, non-load-bearing soil is therefore always removed and the work area is filled with other materials such as gravel, gravel or the like.

Abgesehen von dem erhöhten Transportaufwand führt das Abfahren des nicht tragfähigen Aushubs zu Endlagerproblemen, da die hierzu notwendigen Erddeponien immer rarer werden. Andererseits wird kostbares, standfestes Rohmaterial eingebaut, welches für höherwertige Einsätze verwendbar ist.Aside from the increased transport costs, the removal of the unsustainable excavation leads to repository problems, as the necessary landfills are becoming increasingly rare. On the other hand precious, stable raw material is installed, which can be used for high-quality applications.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung anzugeben, mit der ein ausgehobener, nicht tragfähiger Boden zu einem standfesten Baumaterial aufgearbeitet werden kann.The invention has for its object to provide a device with which an excavated, unsustainable floor can be worked up to a stable construction material.

Die Aufgabe wird erfindungsgemäß nach den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object is achieved according to the characterizing features of claim 1.

Das ausgehobene Erdreich wird im Aufgabetisch von einer Konditioniereinrichtung aufbereitet, wobei es mit einer erforderlichen Menge Kalk, Zement, Tonmehl oder dgl. Zugabematerial zu einem standfesten Baumaterial vermischt wird. Dabei wird das Zugabematerial im Bereich der Konditioniereinrichtung zugeführt.The excavated soil is processed in the feed table by a conditioning device, whereby it is mixed with a required amount of lime, cement, clay powder or the like. Additive material to form a stable construction material. The material to be added is fed into the area of the conditioning device.

In Weiterbildung der Erfindung führt das Transportband das konditionierte Erdreich in einen Mischer, wobei vor dem Mischer eine Wiegeeinrichtung für das über das Transportband herangeführte konditionierte Erdreich vorgesehen ist, so daß die über die zweite Dosiereinrichtung zugeführte Menge des Zugabematerials in Abhängigkeit vom Ausgangssignal der Wiegeeinrichtung geregelt sein kann.In a further development of the invention, the conveyor belt leads the conditioned soil into a mixer, a weighing device being provided in front of the mixer for the conditioned soil brought in via the conveyor belt, so that the quantity of the addition material supplied via the second metering device is regulated as a function of the output signal of the weighing device can.

In vorteilhafter Weiterbildung der Erfindung ist die Vorrichtung auf einem Fahrgestell angeordnet, so daß jederzeit vor Ort die notwendige Aufbereitung des Erdaushubs zu einem standfesten Baumaterial erfolgen kann. Diese fahrbare Einheit kann aufgrund ihrer geschlossenen stationär versetzbaren Bauart auch für kleinere Projekte und auch in bebauten Gebieten eingesetzt werden. Die Vorrichtung kann auch als fest montierte Einheit in einem Zwischenlager vorgesehen sein, zu dem der aufzuarbeitende Erdaushub unter Berücksichtigung vertretbar kurzer Zufahrtswege aufgearbeitet werden kann.In an advantageous development of the invention, the device is arranged on a chassis, so that the necessary preparation of the excavation to a stable construction material can take place on site at any time. This mobile unit can also be used for smaller projects and in built-up areas due to its closed, relocatable design. The device can also be provided as a permanently mounted unit in an interim storage facility, to which the excavated earth to be worked up can be worked up taking into account reasonably short access routes.

Wie sich aus Fig. 1, 2 ergibt, sind zwei Vorratssilos 21a und 21b vorgesehen, welche zweckmäßig gemeinsam eine Dosiereinrichtung 7 speisen, die auf den Ausgabetisch 2 mündet.While the storage silos 22 are arranged above the continuous mixer 3, another storage silo 21 is held in the frame 40 approximately above the foot of the conveyor belt 4. As can be seen from FIGS. 1, 2, two storage silos 21a and 21b are provided, which expediently feed together a metering device 7 which opens onto the delivery table 2.

Das Transportband 4 führt von dem Aufgabetisch 2 Erdreich in Transportrichtung 20 ab, nachdem es in einer Konditioniereinrichtung 5 aufbereitet wurde. Die Konditioniereinrichtung 5 ist im Ausführungsbeispiel aus einem Rotor 50 gebildet, welcher das auf den Aufgabetisch 2 geschüttete, grobklumpige Erdreich zerkleinert und derart konditioniert, daß es für eine eventuelle notwendige weitere Aufbereitung in dem Durchlaufmischer 3 geeignet ist. Der Rotor oder die Rotoren sind bevorzugt auswechselbar. Ein Rotor 50 kann als Fräsrotor oder auch als Rotor mit Schlagarmen oder dgl. ausgebildet sein. Auch können im Aufgabetisch 2 eine oder mehrere Wellen 50a, 50b aufweisende, austauschbare Konditioniereinrichtungen 5' zum Zerkleinern und Mischen des aufzuarbeitenden Erdaushubs angeordnet sein. Bevorzugt arbeitet der Fräsrotor 5 mit einer höhenverstellbaren Schlagleiste 10 zusammen, wodurch zwischen dem Rotor 50 und der Schlagleiste 10 ein Arbeitsspalt 11 gebildet ist (Fig. 2, 7), dessen Spaltbreite zur Einstellung der Grad der Konditionierung bzw. der gewünschten Korngröße des aufbereiteten Erdreiches veränderbar ist. Bevorzugt rotiert der auswechselbare Fräsrotor 50 dabei in Pfeilrichtung 48, also im Sinne eines Anhebens des zugeführten ErdreichsThe conveyor belt 4 leads soil from the feed table 2 in the transport direction 20 after it has been processed in a conditioning device 5. In the exemplary embodiment, the conditioning device 5 is formed from a rotor 50, which crushes the coarse-lump soil that has been poured onto the feed table 2 and conditions it in such a way that it is suitable for any further processing that may be necessary in the continuous mixer 3. The rotor or the rotors are preferably interchangeable. A rotor 50 can be designed as a milling rotor or also as a rotor with beating arms or the like. One or more interchangeable conditioning devices 5 'having shafts 50a, 50b for comminuting and mixing the excavated earth to be worked up can also be arranged in the feed table 2. The milling rotor 5 preferably works together with a height-adjustable blow bar 10, as a result of which a working gap 11 is formed between the rotor 50 and the blow bar 10 (FIGS. 2, 7), the gap width of which for setting the degree of conditioning or the desired grain size of the prepared soil is changeable. The interchangeable milling rotor 50 preferably rotates in the direction of the arrow 48, that is to say in the sense of lifting the supplied soil

Der Aufgabetisch 2 hat entsprechend der konstruktiven Ausführung der Vorrichtung gemäß Fig. 7 einen zum Fräsrotor 50 abfallenden Boden 55 mit einem Schieber 56, der durch eine Kolben/Zylinder-Einheit 57 gemäß Pfeil 58 hin und her bewegbar ist. Das auf den Aufgabetisch 2 abgeworfene Erdreich wird so vom Schieber 56 mit einem einstellbaren Vorschub dem Fräsrotor 50 zugeführt, der in Pfeilrichtung 48 umläuft und das zugeführte Erdreich anhebt und in Umfangsrichtung nach oben mitnimmt. Das Erdreich wird so erfaßt und im Zusammenwirken mit einer in Drehrichtung 48 oberhalb des Bodens 55 des Schubtisches angeordneten Schlagleiste 10 aufgearbeitet, insbesondere zerkleinert bzw. gekrümelt. Die Schlagleiste 10 kann durch den vorderen Rand einer den Fräsrotor 50 über einen Teilumfang umgehenden, verstellbaren Haube 60 gebildet sein, die einen einstellbaren Arbeitsspalt 11 zwischen Haube und Rotor bestimmt. Abhängig von der Drehzahl des Fräsrotors 50, der Breite und Länge des Arbeitsspaltes 11 sowie der Vorschubgeschwindigkeit des Schiebers 56 ergibt sich eine einstellbare Konditioniergüte des Erdreichs, die den jeweiligen Gegebenheiten angepaßt werden kann. Dabei ist insbesondere eine Zugabe von Zuschlagstoffen wie Kalk, Zement, Tonmehl oder dgl. im Bereich des Fräsrotors 50 vorteilhaft. Als zweckmäßig hat sich die Zugabe in den Arbeitsspalt 1 erwiesen, dort vorteilhaft in Drehrichtung 48 des Rotors 50 kurz hinter dem eine Schlagleiste 10 bildenden vorderen Rand der Haube 60. Im Ausführungsbeispiel nach Fig. 7 mündet die Dosiereinrichtung 7 im Bereich der Schlagleiste 10 in den Arbeitsspalt 11.In accordance with the design of the device according to FIG. 7, the feed table 2 has a bottom 55 which slopes towards the milling rotor 50 and has a slide 56 which can be moved back and forth by a piston / cylinder unit 57 according to arrow 58. The soil thrown onto the feed table 2 is thus fed to the milling rotor by the slide 56 with an adjustable feed 50 supplied, which rotates in the direction of arrow 48 and lifts the supplied soil and takes it upward in the circumferential direction. The soil is thus detected and worked up, in particular crushed or crumbled, in cooperation with a blow bar 10 arranged in the direction of rotation 48 above the base 55 of the sliding table. The blow bar 10 can be formed by the front edge of an adjustable hood 60 which surrounds the milling rotor 50 over a partial circumference and which defines an adjustable working gap 11 between the hood and the rotor. Depending on the speed of the milling rotor 50, the width and length of the working gap 11 and the feed speed of the slide 56, there is an adjustable conditioning quality of the soil, which can be adapted to the particular circumstances. It is particularly advantageous to add additives such as lime, cement, clay powder or the like in the area of the milling rotor 50. The addition into the working gap 1 has proven to be expedient, advantageously there in the direction of rotation 48 of the rotor 50, just behind the front edge of the hood 60 forming a blow bar 10. In the exemplary embodiment according to FIG. 7, the metering device 7 opens into the area of the blow bar 10 in the Working gap 11.

Das durch den Arbeitsspalt 11 tretende, in den Bodenbereich 44 auf das Transportband 4 fallende konditionierte Erdreich kann in der Abzugsmenge zweckmäßig durch eine Blende 9 eingestellt werden (Fig. 2). Hierzu ist ein Blendenschieber 18 vorgesehen, der durch eine hydraulische Kolben/Zylinder-Einheit 49 in Richtung des Doppelpfeils 47 verstellbar ist. Die dadurch einstellbare Durchtrittsöffnung 12 der Blende 9 bestimmt den Volumenstrom des vom Transportband 4 aus dem Bodenbereich 44 abgezogenen konditionierten Erdreiches. Dieses Erdreich wird vor Abwurf in den Durchlaufmischer 3 von einer Wiegeeinrichtung 6 gewichtsmäßig erfaßt, um abhängig von dem Ausgangssignal der Wiegeeinrichtung 6 die Menge des über die Dosiereinrichtung 17 zugeführten Zugabematerials insbesondere automatisch einzustellen. Die Wiegeeinrichtung 6 ist zweckmäßig in dem Transportband 4 integriert.The conditioned soil passing through the working gap 11 and falling into the bottom area 44 onto the conveyor belt 4 can expediently be adjusted by means of an orifice 9 (FIG. 2). For this purpose, an orifice slide 18 is provided, which is adjustable in the direction of the double arrow 47 by means of a hydraulic piston / cylinder unit 49. The thereby adjustable passage opening 12 of the screen 9 determines the volume flow of the conditioned soil drawn from the conveyor belt 4 out of the bottom area 44. The weight of this soil is measured by a weighing device 6 before being discharged into the continuous mixer 3 in order to determine the amount of the feed material supplied via the metering device 17 depending on the output signal of the weighing device 6 especially automatically set. The weighing device 6 is expediently integrated in the conveyor belt 4.

Bevorzugt erfolgt auch eine Messung des Feuchtigkeitsgehaltes des konditionierten Erdreichs, wozu im Bodenbereich 44 z. B. vor der Blende 9 ein Sensor 46 angeordnet sein kann. Zweckmäßig erfolgt die Feuchtemessung kurz vor Abwurf des konditionierten Erdreiches in den Mischer 3, wie dies schematisch in Figur 1 dargestellt ist. Die Feuchtemessung kann z. B. mittels Mikrowellen im Bereich von 5 - 6 Giga Hertz erfolgen, wozu eine entsprechende Meßvorrichtung 70 angeordnet ist. Das Ausgangssignal des Sensors 46 bzw. der Meßvorrichtung 70 kann zusammen mit dem Ausgangssignal der Wiegeeinrichtung 6 einem Steuergerät 80 (Fig. 1) zugeführt sein, welches die Dosiereinrichtung 17 steuert, um eine der Feuchtigkeit und der Masse des vom Transportband 4 zugeführten Materials angepaßte Zugabe des Zugabematerials zu erzielen. Das Steuergerät kann als Potentiometer-Steuerung ausgeführt oder auch eine PC-Steuerung sein.Preferably, the moisture content of the conditioned soil is also measured. B. can be arranged in front of the aperture 9, a sensor 46. The moisture measurement is expediently carried out shortly before the conditioned soil is discharged into the mixer 3, as is shown schematically in FIG. The moisture measurement can e.g. B. by means of microwaves in the range of 5-6 gigahertz, for which purpose a corresponding measuring device 70 is arranged. The output signal of the sensor 46 or the measuring device 70 can be fed together with the output signal of the weighing device 6 to a control unit 80 (FIG. 1) which controls the metering device 17 by an addition adapted to the moisture and the mass of the material fed by the conveyor belt 4 of the added material. The control unit can be designed as a potentiometer control or can also be a PC control.

Nach dem Ausführungsbeispiel Figur 2 kann der Schieber 8 des Aufgabetisches 2 auch eine quer zur Längsrichtung 30 liegende hintere Wand eines Aufnahmetroges sein, welche über eine Kolben/Zylinder-Einheit 38 auf den Fräsrotor 50 verfahrbar ist. Das im Aufnahmetrog befindliche Erdreich wird so zwangsgeführt in den Wirkungsbereich des Fräsrotors 50 transportiert.According to the exemplary embodiment in FIG. 2, the slide 8 of the feed table 2 can also be a rear wall of a receiving trough lying transversely to the longitudinal direction 30 and which can be moved onto the milling rotor 50 via a piston / cylinder unit 38. The soil in the receiving trough is thus positively guided into the effective area of the milling rotor 50.

Als Zugabematerial ist ein dem Erdreich Feuchtigkeit entziehendes Material vorgesehen, welches Zement, Kalk, Flugasche, Tonmehl, Bentonit oder dgl. sein kann. Dabei kann über die Dosiereinrichtung 7 als auch über die Dosiereinrichtung 17 gleiches oder auch unterschiedliches Material zugeführt werden; bevorzugt werden über die Dosiereinrichtungen 7 und 17 Kalk zugeführt. Auch können Mischungen als Zugabe dosiert werden; hierzu sind - wie Fig. 1 zeigt - alle Silos 21a, 21b, 22a - d mit getrennt steuerbaren Dosierschnecken ausgerüstet, wodurch eine gequantelte Volumensteuerung, z. B. über die Steuerung 80, möglich ist.A material that removes moisture from the soil is provided as the addition material, which can be cement, lime, fly ash, clay flour, bentonite or the like. The same or different material can be supplied via the metering device 7 and also via the metering device 17; lime is preferably supplied via the metering devices 7 and 17. Mixtures can also be dosed as additives; 1 shows - all silos 21a, 21b, 22a - d equipped with separately controllable dosing screws, whereby a quantized volume control, e.g. B. via the controller 80, is possible.

Um auch trockenes Erdreich verarbeiten zu können, ist zweckmäßig sowohl im Aufgabetisch 2 als auch im Durchlaufmischer 3 eine Wasserzugabe 23 vorgesehen. Die Wasserzugabe kann in Abhängigkeit der Feuchtigkeitsmessung von der Steuerung 80 über ein elektromagnetisches schaltbares Ventil 81 geregelt sein. So kann die zur Konditionierung und spätere Durchmischung mit dem Bindemittel notwendige Feuchtigkeit gewährleistet werden.In order to also be able to process dry soil, it is advisable to add water 23 both in the feed table 2 and in the continuous mixer 3. The addition of water can be regulated as a function of the moisture measurement by the controller 80 via an electromagnetic switchable valve 81. In this way, the moisture required for conditioning and later mixing with the binder can be guaranteed.

Im Ausführungsbeispiel nach Fig. 2 wird das in den Aufnahmetrog abgeworfene Erdreich von der beweglichen Wand 8 in den Arbeitsbereich der Konditioniereinrichtung 5 transportiert und durch den Fräsrotor 50 in Verbindung mit der Schlagleiste 10 aufbereitet. Abhängig von dem zu verarbeitenden Erdreich kann eine Kalkzugabe zweckmäßig sein, wobei die Kalkzugabe bevorzugt in Transportrichtung 20 des Erdreichs vor dem Arbeitsspalt 11, das heißt also vor der Konditioniereinrichtung 5 erfolgt. Das den Arbeitsspalt 11 passierende Erdreich, fällt in dem Bodenbereich 44 auf das Transportband 4 und wird in Transportrichtung 20 abgezogen, wobei der Volumenstrom über die Durchtrittsöffnung 12 der Blende 9 einstellbar ist. Das Gewicht des Volumenstromes wird von der bevorzugt in dem Transportband 4 integrierten Wiegeeinrichtung 6 vor Abwurf in den Durchlaufmischer 3 erfaßt und entsprechend dem Ausgangssignal der Wiegeeinrichtung 6 über die Dosiereinrichtung 17 entsprechende Anteile Zugabematerial aus den Vorratssilos 22 zugeführt. In dem zu seiner Austrittsöffnung 14 zweckmäßig leicht ansteigenden Durchlaufmischer wird die Mischung innig durchgemischt, wobei sich ein trockenes, standfestes Einbaumaterial ergibt, welches zur Verfüllung von Arbeitsräumen im Erdbau, so z. B. von Arbeitsgräben, Kanalisationsgräben und dgl. verwendbar ist.In the exemplary embodiment according to FIG. 2, the soil thrown into the receiving trough is transported from the movable wall 8 into the working area of the conditioning device 5 and processed by the milling rotor 50 in connection with the blow bar 10. Depending on the soil to be processed, a lime addition may be expedient, the lime addition preferably taking place in the transport direction 20 of the soil in front of the working gap 11, that is to say in front of the conditioning device 5. The soil passing through the working gap 11 falls in the bottom area 44 onto the conveyor belt 4 and is drawn off in the transport direction 20, the volume flow being adjustable via the passage opening 12 of the orifice 9. The weight of the volume flow is recorded by the weighing device 6, which is preferably integrated in the conveyor belt 4, before being discharged into the continuous mixer 3 and, in accordance with the output signal of the weighing device 6, the corresponding portions of addition material are fed from the storage silos 22 via the metering device 17. In the flow mixer, which expediently rises slightly to its outlet opening 14, the mixture is thoroughly mixed, resulting in a dry, stable paving material which is used for filling work spaces in earthworks, for. B. of trenches, sewer trenches and the like. Usable.

Da die Menge der zugesetzten Bindemittel relativ groß sein kann, können die Vorratssilos 21, 22 nur eine bestimmte Betriebszeit der Vorrichtung garantieren. Es ist daher vorgesehen, während dem insbesondere kontinuierlichen Betrieb der Vorrichtung das Zugabematerial von einem Großsilofahrzeug 42 (Fig. 6) permanent in die Silos einzuspeisen. Für den Wechsel eines Großsilofahrzeugs 42 ist das in den Vorratssilos 21, 22 gespeicherte Volumen ausreichend, so daß ein Wechsel des Fahrzeugs ohne Arbeitsunterbrechung der Vorrichtung erfolgen kann. Auch können Wechselsilos zweckmäßig sein, die von einem an der Vorrichtung angebauten Manipulator 91 (Kran) zu handhaben sind (Fig. 1).Since the amount of binder added can be relatively large, the storage silos 21, 22 can only guarantee a certain operating time of the device. It is therefore provided that the material to be added is continuously fed into the silos from a large silo vehicle 42 (FIG. 6) during the continuous operation of the device. The volume stored in the storage silos 21, 22 is sufficient for changing a large silo vehicle 42, so that the vehicle can be changed without interrupting the work of the device. Swap silos can also be expedient, which are to be handled by a manipulator 91 (crane) attached to the device (FIG. 1).

Die Vorrichtung nach Fig. 5 weist zwei im wesentlichen gleich große Vorratssilos 21, 22 auf, wobei das Vorratssilo 21 sowohl die erste Dosiereinrichtung 7 als auch die zweite Dosiereinrichtung 17 speist. Das zweite Vorratssilo 22 speist ausschließlich die zweite Dosiereinrichtung 17. Diese Dosiereinrichtung 17 mündet in Transportrichtung 20 des Erdreichs nach der Füllöffnung 19 in den Durchlaufmischer. Dies kann vorteilhaft sein, damit eine aufgrund der Kalkzugabe auftretende Belästigung durch Kalkstaub und dgl. vermieden ist.The device according to FIG. 5 has two storage silos 21, 22 of essentially the same size, the storage silo 21 feeding both the first metering device 7 and the second metering device 17. The second storage silo 22 exclusively feeds the second metering device 17. This metering device 17 opens in the transport direction 20 of the soil after the filling opening 19 into the continuous mixer. This can be advantageous in order to avoid annoyance caused by lime dust and the like due to the addition of lime.

Die in Fig. 4 dargestellte Konditioniereinrichtung 5' im Aufnahmetrog besteht aus zwei Rotoren 50a, 50b, welche zur Konditionierung des Erdreiches zusammenarbeiten. Das konditionierte Erdreich fällt durch ein im Boden des Aufnahmetroges 2 vorgesehenes Gitter, wobei die Gitteröffnungen dem gewünschten Konditionierungsgrad des Erdreichs angepaßt gewählt sind.The conditioning device 5 ′ shown in FIG. 4 in the receiving trough consists of two rotors 50a, 50b, which work together to condition the soil. The conditioned soil falls through a grating provided in the bottom of the receiving trough 2, the grating openings being selected to match the desired degree of conditioning of the soil.

In den gezeigten Ausführungsbeispielen liegen die Fräsrotoren 50 quer zur Längsmittelachse 30 der Vorrichtung 1; insbesondere bei der Anordnung von zwei Fräsrotoren 50a, 50b, wie sieIn the exemplary embodiments shown, the milling rotors 50 lie transversely to the longitudinal central axis 30 of the device 1; in particular with the arrangement of two milling rotors 50a, 50b as shown
