Description
TRANSPORTFAHRZEUG UND VERFAHREN ZUR ANLIEFERUNG EINES BINDEMITTEL/ ZUS CHLAGSGEMI SCHS TRANSPORT VEHICLE AND METHOD FOR DELIVERING A BINDING AGENT / TO CHLAGSGEMI SCHS
Die vorliegende Erfindung betrifft ein Verfahren zur Anlieferung und Aufbereitung eines Bindemittel/Zuschlagsgemischs an der Baustelle und ein Transportfahrzeug zur Anlieferung eines Bindemittel/Zuschlagsgemischs.The present invention relates to a method for the delivery and preparation of a binder / aggregate mixture at the construction site and a transport vehicle for the delivery of a binder / aggregate mixture.
Bindemittel/Zuschlagsgemische, z.B. Beton wird bislang einbaufertig mittels Transportfahrzeugen an die Baustelle geliefert. Diese Transportfahrzeuge haben einen, oft als Mischtrommel ausgebildeten, Behälter, in dem ein Bindemittel, insbesondere Zement, und Zuschlagsstoffe wie z. B. Sand und dergleichen zusammen mit Wasser angemischt und einbaufertig an die Baustelle geliefert wird.Binder / aggregate mixtures, e.g. So far, concrete has been delivered to the construction site ready for installation by means of transport vehicles. These transport vehicles have a container, often designed as a mixing drum, in which a binder, in particular cement, and additives such. B. sand and the like mixed together with water and delivered ready for installation to the construction site.
Dies ist in den Fällen problematisch, in welchen der Fahrweg des Transportfahrzeugs zum Einbauort aufgrund der örtlichen Bedingungen z. B. in einem Tunnel besonders lang ist und in Fällen, in denen nur kleine Chargen zur Verarbeitung benötigt werden. Im ersten Fall muss das einbaufertige Gemisch so eingestellt werden, dass es wenigstens eine Stunde verarbeitbar ist und daher nicht bereits während der Fahrt abbindet. Doch muss dann bei der Verarbeitung durch die Zugabe von Beschleunigern sicher gestellt werden, dass die Betonmischung nach dem Aufbringen sclinell abbindet. Da eine lange Verarbeitungszeit notwendig ist, muss relativ viel Beschleuniger zugesetzt werden, um diesen Anforderungen zu genügen.This is problematic in the cases in which the route of the transport vehicle to the installation site due to the local conditions such. B. is particularly long in a tunnel and in cases where only small batches are required for processing. In the first case, the ready-to-install mixture must be set so that it can be processed for at least one hour and therefore does not set during the journey. However, when adding accelerators, it must then be ensured during processing that the concrete mixture sets sclinell after application. Since a long processing time is necessary, a relatively large amount of accelerator must be added in order to meet these requirements.
Im zweiten Fall, indem nur geringe Chargen benötigt werden, wie z. B. beim Erstellen von Türmen, z. B. für Windräder, wo der Beton chargenweise an die Turmspitze transportiert und verarbeitet wird, besteht der Nachteil darin, dass das Transportfahrzeug mit einem nur teilweise gefüllten Mischbehälter losfährt, was die Anlieferpreise für den Beton drastisch verteuert.In the second case, by only requiring small batches, such as B. when building towers, e.g. B. for wind turbines, where the concrete is transported and processed in batches to the top of the tower, the disadvantage is that the transport vehicle starts off with a partially filled mixing container, which drastically increases the delivery prices for the concrete.
Es ist Aufgabe der Erfindung, ein Transportfahrzeug und ein Verfahren zur Anlieferung und Aufbereitung von Beton zu schaffen, die eine individuelle Verarbeitung mit geringen Beschleunigereinsatz unabhängig von der Dauer des Anfahrweges erlauben. Diese Aufgabe wird durch ein Transportfahrzeug gemäß Anspruch 4 und ein Verfahren gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildung der Erfindung sind Gegenstand der zugehörigen Unteransprüche. Erfindungsgemäß weist das Transportfahrzeug neben dem Behälter, der ein geschlossener oder offener Behälter in Art einer Mischtrommel sein kann, eine Mischeinrichtung auf, in welcher das vorzugsweise trockene bzw. noch weit gehend trockene bzw. erdfeuchte Gemisch aus Bindemittel und Zuschlagstoffen mit Wasser vermischt und somit verarbeitungsfertig angemacht. Die Mischeinrichtung ist Merfür mit einem Wasseranschluss versehen bzw. mit einem Wassertank verbunden, der die einbaufertige Zubereitung des Bindemittel/Zuschlagsgemischs erlaubt. Die Mischeinrichtung kann selbstverständlich für die Zugabe von Additiven ausgebildet sein. Hierfür weist die Mischeinrichtung die erforderlichen Zugabeeinrichtungen bzw. Verbindungen mit Tank für Additiven auf. Die Mischeinrichtung kann ein an sich bekannter Mischer, z. B. ein kontinuierlicher oder chargenweise arbeitender Mischer, insbesondere ein Konusmischer sein, der das noch nicht angemachte Bindemittel/Zuschlagsgemisch aufnimmt, mit Wasser vermengt und an eine Betonpumpe oder eine Spritzanlage abgibt. Es ist selbstverständlich nach dem fertigen Anmischen in der Mischeinrichtung auch jede andere, z.B. manuelle, Verarbeitung des einbaufertigen Gemischs, nachfolgend beispielsweise Betongemischs, denkbar. Da die Betonmischung erst am Einbauort in der Mischeinrichtung angemacht wird, kann die Verarbeitungszeit des Betons drastisch reduziert werden, was es ermöglicht, den Einsatz von kostspieligen Beschleunigern stark zu reduzieren bzw. gegebenenfalls auf diese sogar zu verzichten.It is an object of the invention to provide a transport vehicle and a method for delivery and preparation of concrete, which allow individual processing with little use of accelerators regardless of the duration of the approach. This object is achieved by a transport vehicle according to claim 4 and a method according to claim 1. Advantageous developments of the invention are the subject of the associated subclaims. According to the invention, in addition to the container, which can be a closed or open container in the form of a mixing drum, the transport vehicle has a mixing device in which the preferably dry or largely dry or earth-moist mixture of binder and additives is mixed with water and thus ready for processing turned on. The mixing device is provided with a water connection for Mer or connected to a water tank that allows ready-to-install preparation of the binder / aggregate mixture. The mixing device can of course be designed for the addition of additives. For this purpose, the mixing device has the necessary addition devices or connections with a tank for additives. The mixing device can be a mixer known per se, e.g. B. a continuous or batch mixer, in particular a cone mixer, which takes up the unpainted binder / aggregate mixture, mixed with water and delivers it to a concrete pump or a spraying system. After the finished mixing in the mixing device, it is of course also conceivable for any other, for example manual, processing of the ready-to-install mixture, hereinafter for example a concrete mixture. Since the concrete mix is only made up at the installation site in the mixing device, the processing time of the concrete can be drastically reduced, which makes it possible to greatly reduce the use of expensive accelerators or even to do without them if necessary.
Des weiteren ist es möglich, mit dem Fahrzeug an eine Baustelle, z. B. an den Turm eines Windrades zu fahren und dort chargenweise verarbeilbare Mengen an einbaufertigem Beton anzumischen und über den Tag in vielen kleineren Chargen sukzessive abzugeben, wobei also nicht wie beim Stand der Technik jede Charge einzeln angeliefert werden muss. Die Anlieferung des Betons wird damit deutlich günstiger.Furthermore, it is possible to take the vehicle to a construction site, e.g. B. drive to the tower of a wind turbine and mix batches of ready-to-install concrete that can be processed in batches and gradually deliver them in many smaller batches over the course of the day, so that each batch does not have to be delivered individually as in the prior art. This makes delivery of the concrete much cheaper.
Selbstverständlich ist die Erfindung nicht auf Trockenbeton bzw. auf die Anmischung von Fertigbeton beschränkt sondern erstreckt sich auf alle Arten von Bindemittel/Zuschlagsgemischen.Of course, the invention is not limited to dry concrete or to the mixing of ready-mixed concrete, but extends to all types of binders / aggregate mixtures.
Vorzugsweise sind mit der Mischeinrichtung Dosiereinrichtungen für die Wasserzufuhr bzw. die Zufuhr der Additive verbunden. Nach der Abgabe der gewünschten Betoncharge bzw. nach Abschluss des kontinuierlichen Anlieferungsverfahrens wird die Mischeinrichtung gereinigt und ist somit für den nächsten Einsatz bzw. die Zubereitung der nächsten Charge.Metering devices for the water supply or the supply of the additives are preferably connected to the mixing device. After delivery of the desired batch of concrete or after completion of the continuous delivery process, the mixing device is cleaned and is thus ready for the next use or preparation of the next batch.
Durch die Erfindung ist es auch möglich, kleinere Chargen an verschiedenen Baustellen abzuliefern, was wiederum die Anlieferungskosten für den Beton beträchtlich verringert.The invention also makes it possible to deliver smaller batches to different construction sites, which in turn considerably reduces the delivery costs for the concrete.
Verfahrensmäßig ist die Erfindung dadurch gekennzeichnet, dass die einbaufertige Zubereitung des Bindemittel/Zuschlagsgemisches vor Ort, d. h. am Einsatzort erfolgt, wodurch das Vorhalten einer Verarbeitungszeit für den Anfahrweg entfällt und darüberhinaus eine Zubereitung nur eines Teiles des Behälterinhaltes des Transportfahrzeugs möglich ist. Eine derartige Mischeinrichtung muss dann nicht zwangsweise am Transportfahrzeug angeordnet sein, obwohl dies sehr vorteilhaft ist, sondern kann auch an der Baustelle selbst stehen.In terms of method, the invention is characterized in that the ready-to-install preparation of the binder / aggregate mixture on site, i. H. takes place at the place of use, which eliminates the need to maintain a processing time for the approach path and also allows only part of the container content of the transport vehicle to be prepared. Such a mixing device then does not necessarily have to be arranged on the transport vehicle, although this is very advantageous, but can also be located on the construction site itself.
In einer vorteilhaften Ausbildung kann auch vorgesehen sein, dass die Mischeinrichtung lösbar an dem Transportfahrzeug gehalten und für den Einsatz auf der Baustelle abstellbar ist. In diesem Fall muss die Mischeinrichtung über die notwendigen Dosiereinrichtungen und Wasseranschlüsse bzw. Anschlüsse für Additive verfügen, um eine Zubereitung des Betons in Verbindung mit dem Transportfahrzeug oder auch autark davon zu ermöglichen.In an advantageous embodiment, it can also be provided that the mixing device is detachably held on the transport vehicle and can be parked for use on the construction site. In this case, the mixing device must have the necessary metering devices and water connections or connections for additives in order to enable preparation of the concrete in connection with the transport vehicle or also independently of it.
Auch wenn es vorteilhaft ist, dass die Mischeinrichtung auf ein- und demselben Fahrzeug wie der Behälter selbst angeordnet ist, so können diese Komponenten auch getrennt auf einem Gespann angeordnet sein, wobei dann beispielsweise sowohl auf dem Zugfahrzeug als auch auf dem Anhänger jeweils ein Behälter und auf dem Zugfahrzeug oder dem Anhänger eine Mischeinrichtung angeordnet sein können. Es ist selbstverständlich möglich, mehrere Behälter als auch mehrere Mischeinrichtungen auf dem Transportfahrzeug anzuordnen.Even if it is advantageous for the mixing device to be arranged on one and the same vehicle as the container itself, these components can also be arranged separately on a combination, in which case, for example, both a container and on the towing vehicle and on the trailer a mixing device can be arranged on the towing vehicle or the trailer. It is of course possible to arrange several containers as well as several mixing devices on the transport vehicle.
Darüber hinaus bedarf es keiner Erläuterung, dass neben der Mischeinrichtung alle notwendigen Pumpen und Dosiereinrichtungen vorzugsweise ebenfalls auf dem Transportfahrzeug angeordnet sind.In addition, no explanation is required that in addition to the mixing device, all the necessary pumps and metering devices are preferably also arranged on the transport vehicle.
Vorzugsweise wird die Hydraulik für die Betätigung eines als Mischtrommel ausgebildeten Behälters auch zur Betätigung der Mischeinrichtung verwendet. Hierfür weist das Transportfahrzeug alle erforderlichen elektrischen Schalteinrichtungen auf. Die Erfindung wird nachfolgend beispielsweise anhand der schematischen Zeichnung beschrieben. In dieser zeigen:The hydraulics for actuating a container designed as a mixing drum are preferably also used to actuate the mixing device. The transport vehicle has all the necessary electrical switching devices for this. The invention is described below, for example, using the schematic drawing. In this show:
Fig. 1 eine schematische Seitensicht eines Transportfahrzeugs in Form eines Fahrmischers mit einer Mischtrommel als Behälter und einem abnehmbaren Konusmischer als Mischeinrichtung, Fig. 2 ein Transportfahrzeug gemäß Fig. 1 mit integriertem Förderband, und1 shows a schematic side view of a transport vehicle in the form of a truck mixer with a mixing drum as a container and a removable cone mixer as a mixing device, FIG. 2 shows a transport vehicle according to FIG. 1 with an integrated conveyor belt, and
Fig. 3 ein Transportfahrzeug gemäß Fig. 1 mit integrierter Betonpumpe.3 shows a transport vehicle according to FIG. 1 with an integrated concrete pump.
Der Fahrmischer 10 hat ein Chassis 12, auf dem ein Behälter für ein Bindemittel/Zuschlagsgemisch in Form einer Mischtrommel 14 drehbar angetrieben gehalten ist. Der Antrieb 16 der Trommel 14 befindet sich an ihrer Vorderseite. An der Rückseite der Mischtrommel 14 ist das Zugabe- bzw. Auslassende 18 angeordnet. Unter diesem Auslassende 18 ist ein Konusmischer 20 lösbar gehalten. Der Konusmischer ist ausgebildet für die Aufbereitung eines in der Mischtrommel 14 an die Baustelle angelieferten Trockenbetongemischs mit Wasser und Additiven. Hierfür ist der Mischer 20 mit an sich bekannten Mischorganen versehen. Das Aufbereiten des in der Mischtrommel 14 befindlichen Trockengemiscb.es erfolgt an der Baustelle entweder kontinuierlich oder chargenweise. Hierfür weist das Transportfahrzeug vorzugsweise einen Wassertank 22 auf, welcher mit der Mischeinrichtung 20 verbunden ist. Das Wasser kann jedoch auch an der Baustelle vorgehalten werden. Der Fahraiischer 10 enthält weiterhin eine Hydraulikpumpe mit Motor 24 und einem Hydrauliktank 26, welche für den Antrieb 16 der Mischtrommel 14 als auch für den Antrieb des Konusmischers 20 dienen. Für die Betätigung des Konusmischers 20 ist ein Schaltkasten 28 vorgesehen, über den sich der Konusmischer 20 selbst betätigen lässt als auch die notwendigen Dosier bzw. Zufuhreinrichtungen für Wasser und Additive. Die hierfür vorzusehenden Leitungen und Pumpen sind in der Zeichnung nicht dargestellt, ebenso wie gegebenenfalls vorzusehende Tanks für Additive, die beim gebrauchsfertigen Aufbereiten der Betonmischung mitzugegeben werden.The truck mixer 10 has a chassis 12 on which a container for a binder / aggregate mixture in the form of a mixing drum 14 is rotatably driven. The drive 16 of the drum 14 is located on its front. The addition or outlet end 18 is arranged on the rear side of the mixing drum 14. A cone mixer 20 is detachably held under this outlet end 18. The cone mixer is designed for the treatment of a dry concrete mixture with water and additives that is delivered to the construction site in the mixing drum 14. For this purpose, the mixer 20 is provided with mixing elements known per se. The processing of the dry mix located in the mixing drum 14 takes place at the construction site either continuously or in batches. For this purpose, the transport vehicle preferably has a water tank 22 which is connected to the mixing device 20. However, the water can also be kept at the construction site. The Fahraiischer 10 further includes a hydraulic pump with a motor 24 and a hydraulic tank 26, which serve for the drive 16 of the mixing drum 14 and for the drive of the cone mixer 20. For the actuation of the cone mixer 20, a switch box 28 is provided, via which the cone mixer 20 can be actuated itself, as well as the necessary metering or supply devices for water and additives. The lines and pumps to be provided for this purpose are not shown in the drawing, as are any tanks for additives to be provided, which are added when the concrete mixture is ready for use.
Die in den Figuren 2 und 3 gezeigten Transportfahrzeuge sind prinzipiell in gleicher Weise wie das Transportfahrzeug aus Fig. 1 aufgebaut. Identische oder funktionsgleiche Teile sind hierbei mit identischen Bezugszeichen versehen. Selbstverständlich können die in den unterschiedlichen Figuren gezeigten Elemente in beliebiger Weise miteinander kombiniert werden. In Fig. 2 ist ein Mischerfahrzeug 30 gezeigt, bei dem Am Ausgang des Konusmischers 20 eine Transporteinrichtung 32 in Form eines Förderbandes angeordnet ist, welches das fertig mit Wasser und gegebenenfalls Additiven angerührte Gemisch zum Einsatzbereich der Baustelle transportiert.The transport vehicles shown in FIGS. 2 and 3 are basically constructed in the same way as the transport vehicle from FIG. 1. Identical or functionally identical parts are provided with identical reference symbols. Of course, the elements shown in the different figures can be combined with one another in any way. 2 shows a mixer vehicle 30, in which a transport device 32 in the form of a conveyor belt is arranged at the exit of the cone mixer 20 and transports the mixture, which has been mixed with water and optionally additives, to the application area of the construction site.
Die hierfür erforderlichen Steuerungen erlauben eine beliebige Ausrichtung des Förderbandes in horizontaler und vertikaler Richtung, sind jedoch in der Zeichnung nicht dargestellt.The controls required for this allow any orientation of the conveyor belt in the horizontal and vertical directions, but are not shown in the drawing.
Fig. 3 zeigt einen Mischerwagen 34 mit der Anordnung einer Förderpumpe 36 am Ausgang der Mischeinrichtung 20, welche das fertig mit Wasser und gegebenenfalls Additiven angerührte Gemisch zum Einsatzbereich der Baustelle fördert, wobei eine Förderung auch in vertikal größere Höhen möglich ist.3 shows a mixer wagon 34 with the arrangement of a feed pump 36 at the outlet of the mixing device 20, which conveys the mixture, which has been mixed with water and, if appropriate, additives, to the area of use of the construction site, with delivery also being possible at higher vertical heights.
Sowohl die Transporteinrichtung 32 als auch die Förderpumpe 36 können beide separat oder zusammen an dem Mischerfahrzeug 10,32,34 fest oder lösbar angeordnet sein. Die lösbare Anordnung erlaubt einen festen Einsatz an der Baustelle, während das Mischerfahrzeug selbst unterwegs sein kann. In diesem Fall ist vorzugsweise auch die Mischeinrichtung 20 selbst lösbar an dem Mischerfahrzeug angeordnet. Als Mischeinrichtung 20 können selbstverständlich alle bekannten Formen von Betonmischern verwendet werden, wobei in diesem Fall die Betonpumpe 36 bzw. Transporteinrichtung 32 an der geeigneten Stelle am Transportfahrzeug 10,30,34 anzuordnen ist. Bei dem in den Figuren dargestellten Konusmischer 20 sind sie vorzugsweise unterhalb des Mischers angeordnet.Both the transport device 32 and the feed pump 36 can both be arranged separately or together on the mixer vehicle 10, 32, 34 in a fixed or detachable manner. The detachable arrangement allows permanent use on the construction site, while the mixer vehicle can be on the move. In this case, the mixing device 20 itself is preferably also detachably arranged on the mixer vehicle. All known forms of concrete mixers can of course be used as the mixing device 20, in which case the concrete pump 36 or transport device 32 is to be arranged at a suitable location on the transport vehicle 10, 30, 34. In the cone mixer 20 shown in the figures, they are preferably arranged below the mixer.
Die Transporteinrichtung 32 als auch die Förderpumpe 36 können an der Baustelle entweder am Fahrzeug belassen und genutzt werden, oder sie werden vor der Verwendung von dem Transportfahrzeug abgekoppelt und auf der Baustelle an einer geeigneten Stelle plaziert. Nach der Beendigung des Lieferauftrags werden die Elemente 20, 32,36 dann wieder auf dem Transportfahrzeug befestigt.The transport device 32 and the feed pump 36 can either be left on the vehicle and used on the construction site, or they are uncoupled from the transport vehicle before use and placed at a suitable location on the construction site. After the delivery order has ended, the elements 20, 32, 36 are then reattached to the transport vehicle.
Ein wesentlicher Aspekt der Erfindung besteht darin, dass das vom Transportfahrzeug angelieferte Bindemittel/Zuschlaggemisch noch nicht abbindefertig ist, weshalb es beliebig lange transportiert werden kann, ohne dass die Verarbeitungsqualität des Gemischs durch zwischenzeitliches Abbinden während des Transports beeinträchtigt worden ist. Zudem ist man an de Baustelle in der Wahl der Beimengung an Abbindungsbeschleuniger freier und kann die Mischung besser auf die Verarbeitungsbedürfnisse an der Baustelle abstellen. Vorzugs- weise ist an dem Transportfahrzeug auch ein Behälter und eine Zudosiereinrichtung für den Beschleuniger vorgesehen. Zudem ist es durch die neue Technologie möglich, den Beton an mehreren Baustellen in kleinen Chargen anzuliefern, die dann vor Ort abbindefertig angemischt werden.An essential aspect of the invention is that the binder / aggregate mixture delivered by the transport vehicle is not yet ready for setting, which is why it can be transported for any length of time without the processing quality of the mixture being impaired by interim setting during transport. In addition, the construction site is free to choose the addition of setting accelerators and the mixture can be better tailored to the processing needs at the construction site. preferential a container and a metering device for the accelerator are also provided on the transport vehicle. The new technology also makes it possible to deliver the concrete in small batches to several construction sites, which are then mixed on site ready for setting.
Die Mischeinrichtung zum verarbeitungsfertigen Anmischen des Gemischs muss nicht an dem Transportfahrzeug angekoppelt sein, sondern kann auch an der Baustelle vorgesehen sein. The mixing device for mixing the mixture ready for processing does not have to be coupled to the transport vehicle, but can also be provided at the construction site.
