Abstract

The large pile is constructed by means of a multiplicity of injection rods (1), of which one is arranged in the centre of the large pile, while the others are driven into the foundation soil in a distributed manner along the periphery of the large pile. The latter injection rods are then grouted with a hardenable grouting compound. After the hardening of this grouting compound securing the periphery of the large pile, the injection rod arranged in the centre of the large pile is likewise grouted with hardenable grouting compound. The ends of the injection rods (1) showing above the foundation soil are connected to one another by reinforcement (14). Furthermore, a concrete base (15) is poured in the area of these ends. Especially compact and monolithic soil concrete is obtained because first of all the outer injection rods are grouted and then the central injection rods. <IMAGE>

Verfahren zur Herstellung eines Grosspfahles nach Anspruch 1, bei dem Injektionslanzen über den geplanten Bereich des Grosspfahles verteilt in den Baugrund eingetrieben und dann verpresst werden, dadurch gekennzeichnet, dass die in dem mittleren Pfahlbereich eingetriebene Injektionslanze (1) nach dem Verpressen der über dem Umfang des Grosspfahles verteilten Injektionslanzen verpresst wird, dass man dann die aus dem Baugrund herausschauenden Enden der Injektionslanzen (1) durch eine Armierung (14) miteinender verbindet, und dass man schliesslich im Bereich der miteinander verbundenen Enden der Injektionslanzen (1) einen Betonsockel (15) aufbetoniert.2. Method for the production of a large pile according to claim 1, in which injection lances are driven into the subsoil distributed over the planned area of the large pile and then injected, characterized in that the injection lance (1) driven into the central area of the pile after injecting the above injection lances distributed around the circumference of the large pile, that the ends of the injection lances (1) protruding from the ground are then connected to one another by means of a reinforcement (14), and that finally a concrete base (15 ) concreted. Die Erfindung betrifft einen im Baugrund eingebetteten Grosspfahl, bestehend aus einer Vielzahl von in den Baugrund eingetriebenen und mit einer aushärtbaren Verpressmasse verpressten Injektionslanzen, die etwa über den Umfang des Grosspfahles verteilt angeordnet sind.The invention relates to a large pile embedded in the subsoil, consisting of a large number of injection lances driven into the subsoil and grouted with a hardenable grouting compound, which are distributed approximately over the circumference of the large pile. Ein derartiger Grosspfahl ist bekannt.Such a large pole is known. Der Erfindung liegt die Aufgabe zugrunde, einen Grosspfahl zu schaffen, dessen Trag- und Stützfunktion verbessert ist.The object of the invention is to create a large pole whose carrying and supporting function is improved. Die Aufgabe ist dadurch gelöst, dass im Zentrum des Grosspfahles mindestens eine ebenfalls verpresste Injektionslanze angeordnet ist, dass die Enden der Injektionslanzen aus dem Baugrund herausragen und durch eine Armierung miteinander verbunden sind, und dass im Bereich der durch die Armierung verbundenen Enden der Injektionslanzen ein dem Querschnitt des Grosspfahles entsprechender Betonsockel aufbetoniert ist. Der Betonsockel hat einerseits den Zweck, die Armierung zu schützen und soll andererseits einen aufbaufähigen Abschluss schaffen, der die Last auf alle Injektionslanzen und deren Verfestigungsbereich verteilt.The object is achieved in that at least one grouted injection lance is arranged in the center of the large pile, that the ends of the injection lances protrude from the subsoil and are connected to one another by a reinforcement, and that in the area of the ends of the injection lances connected by the reinforcement, a dem Cross-section of the large pile corresponding concrete base is concreted. The purpose of the concrete base is, on the one hand, to protect the reinforcement and, on the other hand, to create a finish that can be built up and which distributes the load across all injection lances and their solidification area. Die Funktion der zentralen Injektionslanze wird durch das Verfahren klar, mit der der erfindungsgemässe Grosspfahl hergestellt werden kann. Dieses Verfahren geht davon aus, dass zunächst Injektionslanzen über den geplanten Bereich des s Grosspfahles verteilt in den Baugrund getrieben werden. Das Erfinderische besteht nun darin, dass die in den mittleren Pfahlbereich eingetriebene Injektionslanze nach dem Verpressen der über den Umfang des Grosspfahles verteilten Injektionslanzen verpresst wird, dass man dann die aus dem Baugrund herausschauenden Enden der Injektionslanzen durch eine Armierung miteinander verbindet, und dass man schliesslich auf die miteinander verbundenen Enden der Injektionslanzen einen Betonsockel aufsetzt.The function of the central injection lance becomes clear from the method with which the large pile according to the invention can be manufactured. This method assumes that injection lances are first driven into the subsoil over the planned area of the large pile. The inventive thing is that the injection lance driven into the central pile area is injected after the injection lances distributed over the circumference of the large pile have been injected, that the ends of the injection lances protruding from the subsoil are then connected to one another by means of reinforcement, and that finally the connected ends of the injection lances are placed on a concrete base. Zu empfehlen ist, dass man zunächst den äusseren Bereich und erst danach, wenn dieser ausgehärtet ist, den inneren Bereich verpresst. Dadurch werden die zwischenzeitlich verfestigten äusseren Bereiche teilweise wieder aufgebrochen und die Bruchlücken erneut verpresst. Auf diese Weise wird ein ganz besonders dichter und monolithischer Erdbeton gebildet.It is recommended that you first press the outer area and only then, when this has hardened, press the inner area. As a result, the outer areas that have meanwhile solidified are partially broken up again and the fracture gaps are grouted again. In this way, a particularly dense and monolithic soil concrete is formed. Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung beschrieben. Es zeigtAn embodiment of the invention is described below with reference to the drawing. It shows Fig. 1 einen Grosspfahl;1 shows a large pole; Fig. 2 einen Schnitt II-II durch den in Fig. 1 gezeigten Grosspfahl;FIG. 2 shows a section II-II through the large pile shown in FIG. 1; Fig. 3 eine Ansicht von oben auf den in Fig. 1 gezeigten Grosspfahl.FIG. 3 is a view from above of the large pile shown in FIG. Zur Herstellung des in Fig. 1 bis 3 dargestellten Grosspfahles werden zunächst Injektionslanzen 1 über den Bereich des herzustellenden Grosspfahles verteilt in den Boden 4 eingetrieben, und vorerst die über den Umfang des Grosspfahles verteilten Injektionslanzen mit einer aushärtbaren Verpressmasse verpresst. Diese besteht aus einem Mörtel, dem gegebenenfalls eine auf einem modifizierten Silicat basierende Flüssigkeit oder andere Zusatzmittel beigemengt sind. Nach dem Aushärten der Verpressmasse dieser äusseren Injektionslanzen wird auch die in der Mitte des Grosspfahles angeordnete Injektionslanze verpresst. Der Abstand der Injektionslanzen sowie die Injektionsintensität werden so gewählt, dass sich die Verfestigungsbereiche 5 verzahnen oder ineinander übergehen. Auf diese Weise wird praktisch der gesamte von den Injektionslanzen 1 eingefasste Erdbereich sowie ein sich um die Rohre erstreckender äusserer Ring zu Erdbeton umgeformt. Auf die herausschauenden Enden der Injektionslanzen 1 wird dann eine Armierung 14 aufgesetzt. Danach wird auf die mit der Armierung 14 verbundenen Enden der Injektionslanzen ein Sockel 15 aufbetoniert, auf dem dann die Last aufgebracht werden kann.To produce the large pile shown in FIGS. 1 to 3, injection lances 1 are first driven into the ground 4 distributed over the area of the large pile to be produced, and first the injection lances distributed over the circumference of the large pile are pressed with a hardenable grouting compound. This consists of a mortar to which, if necessary, a liquid based on a modified silicate or other additives are added. After the grouting compound of these outer injection lances has hardened, the injection lance arranged in the middle of the large pile is also grouted. The distance between the injection lances and the injection intensity are selected in such a way that the solidification areas 5 interlock or merge into one another. In this way, practically the entire area of soil bordered by the injection lances 1 and an outer ring extending around the pipes are formed into soil concrete. A reinforcement 14 is then placed on the protruding ends of the injection lances 1 . Thereafter, a base 15 is concreted onto the ends of the injection lances connected to the reinforcement 14, on which base the load can then be applied.
