PATENTANSPRÜCHEPATENT CLAIMS 1. Baufundament, bestehend aus rasterförmig verteilt in den Baugrund getriebenen und mit einer atishärtbaren Ver-pressmasse verpresste Injektionslanzen, dadurch gekennzeichnet, dass die Injektionslanzen (1) mit ihren Enden aus dem Baugrund (4) herausragen und dass auf jedes herausragende Ende eine Fundamentplatte (11) aufgesetzt ist.1. Building foundation, consisting of injection lances driven into the subsoil and distributed in a grid pattern and grouted with a hardenable grouting compound, characterized in that the ends of the injection lances (1) protrude from the subsoil (4) and that a foundation plate ( 11) is attached. 2. Fundament nach Anspruch 1, dadurch gekennzeichnet, dass die Fundamentplatten (11) an ihrer Unterseite mit einer Ausnehmung (13) zur Aufnahme des betreffenden Injektionslanzen-Endes versehen sind, wobei das Ende soweit aus dem Baugrund (4) herausragt, dass die Fundamentplatte (11) gerade auf dem Baugrund (4) aufsitzt.2. Foundation according to claim 1, characterized in that the foundation plates (11) are provided on their underside with a recess (13) for receiving the relevant injection lance end, the end protruding from the ground (4) so far that the foundation plate (11) sits straight on the ground (4). 3. Fundament nach Anspruch 1, dadurch gekennzeichnet, dass sich die Fundamentplatten (11) nicht berühren.3. Foundation according to claim 1, characterized in that the foundation plates (11) do not touch. 1010 1515 2020 2525 Die Erfindung betrifft ein Baufundament, bestehend aus rasterförmig verteilt in den Baugrund getriebenen und mit einer aushärtbaren Verpressmasse verpressten Injektionslanzen.The invention relates to a building foundation consisting of injection lances which are driven into the subsoil in a grid pattern and are pressed with a hardenable grouting compound. Ein derartiges Baufundament ist bekannt.Such a building foundation is known. Der Erfindung liegt die Aufgabe zugrunde, eine einfache und kostengünstige Möglichkeit zu schaffen, um insbesondere bei grösserer Belastung des Fundamentes, beispielsweise dann, wenn es zum Tragen eines Dammes dienen soll, die Last an den stabilsten Punkten des Fundamentes in dieses einzuleiten. 30The object of the invention is to provide a simple and inexpensive way of transferring the load to the most stable points of the foundation, particularly when the foundation is subject to greater loads, for example when it is intended to support a dam. 30 Die Aufgabe ist erfindungsgemäss dadurch gelöst, dass die Injektionslanzen mit ihren Enden aus dem Baugrund herausragen und dass auf jedes herausragende Ende eine Fundamentplatte aufgesetzt ist.The object is achieved according to the invention in that the injection lances protrude with their ends from the subsoil and that a foundation plate is placed on each protruding end. Die zur Lastaufnahme am besten geeigneten Punkte des Fundamentes sind die Injektionslanzen. Um diese bilden sich nach dem Verpressen Kernbereiche heraus, die je nach der aufgewendeten Menge an Verpressmasse einen Abstand zueinander haben oder ineinander fliessen oder sich gegenseitig verzahnen. Die möglicherweise zwischen den Kernbereichen verbleibenden nichtverpressten Bereiche sind zur Lastaufnahme ungeeignet. Sie können jedoch auf andere Weise nützlich sein, beispielsweise um einen Wasserstau zu verhindern. Auch aus Kostengründen kann es erstrebenswert sein, zwischen den Kernbereichen Lücken zu lassen. Schliesslich ist das vollständige Verpressen eines Baugrundes auch deshalb gefährlich,The most suitable points of the foundation for load absorption are the injection lances. After pressing, core areas form around these, which, depending on the amount of pressing compound used, are at a distance from one another or flow into one another or interlock with one another. The uncompressed areas possibly remaining between the core areas are unsuitable for load bearing. However, they can be useful in other ways, such as preventing water stagnation. For cost reasons, too, it can be desirable to leave gaps between the core areas. Finally, the complete grouting of a subsoil is also dangerous because weil neben dem Baugrund Anhebungen auftreten können.because elevations can occur next to the subsoil. 3535 4040 4545 In jedem Falle gestatten die Fundamentplatten eine einwandfreie und statisch günstige Einleitung der Last in das Fundament. Die Verwendung von Fundamentplatten hat gegenüber einer geschlossenen Betondecke ausserdem den Vorteil, dass die Fundamentplatten vorgefertigt und am Bauort einfach und schnell montiert werden können. Nicht nur die Herstellung, sondern auch die Montage sind damit kostengünstig.In any case, the foundation plates allow a perfect and statically favorable introduction of the load into the foundation. Compared to a closed concrete ceiling, the use of foundation plates also has the advantage that the foundation plates can be prefabricated and assembled quickly and easily on site. Not only the production, but also the assembly are therefore inexpensive. Gemäss einer zweckmässigen Weiterbildung können die Fundamentplatten an ihrer Unterseite mit einer Ausnehmung zur Aufnahme des über den Baugrund herausragenden Endes der Injektionslanzen versehen werden, wobei das Ende soweit aus dem Baugrund herausragt, dass die Fundamentplatte gerade auf dem Baugrund aufsitzt.According to an expedient further development, the foundation plates can be provided on their underside with a recess for accommodating the end of the injection lances protruding above the subsoil, the end protruding from the subsoil so far that the foundation plate just sits on the subsoil. Eine andere Weiterbildung kann darin bestehen, dass sich die Fundamentplatten nicht berühren.Another development can be that the foundation plates do not touch. Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen beschrieben.An embodiment of the invention is described below with reference to the drawings. Es zeigen:Show it: Fig. 1 eine Ansicht von oben auf das Fundament;1 is a top view of the foundation; Fig. 2 einen Schnitt II—II durch das Fundament nach Fig. 1;Fig. 2 shows a section II-II through the foundation according to Fig. 1; Fig. 3 einen Ausschnitt aus Fig. 2, welcher das obere Ende einer Injektionslanze mit aufgesetzter Fundamentplatte zeigt.FIG. 3 shows a detail from FIG. 2, which shows the upper end of an injection lance with a foundation plate in place. Bei dem in den Figuren 1 bis 3 dargestellten Fundament werden Injektionslanzen 1 rasterförmig über die mit einem Damm zu bebauende Fläche 12 verteilt und in den Boden 4 eingetrieben. Dann wird Mörtel, gegebenenfalls mit einer auf modifiziertem Silicat basierenden Flüssigkeit oder anderen Zusatzmitteln, in die Injektionslanzen 1 eingedrückt. Der unter Druck durch Perforationen 2 in der Injektionslanze 1 austretende Mörtel dringt in den umgebenden Baugrund ein. Auf diese Weise bilden sich verfestigte Kernbereiche 5 um die Injektionslanzen 1 herum, die auch ineinanderfliessen oder gegenseitig verzahnt sein können. Auf die aus dem Boden herausschauenden Enden der Injektionslanzen 1 werden Beton-platten 11 aufgesetzt. Diese sind an ihrer Unterseite mit einer Ausnehmung 13 versehen, welche zur Aufnahme der aus dem Boden herausschauenden Enden der Injektionslanzen dienen. Man lässt die Injektionslanzen soweit aus dem Boden herausschauen, dass die Betonplatten 11 gerade auf der Bodenoberfläche aufsitzen. Die Abmessungen der Platten 11 bzw. das Rastermass für das Eintreiben der Injektionslanzen 1 in den Boden sind so gewählt, dass sich die Betonplatten 11 nicht berühren. Auf die Betonplatten 11 wird dann die Erde 12 für den Damm aufgeschüttet, wobei dann die Setzungen vermindert, verhindert oder weitgehend ausgeglichen werden.In the case of the foundation shown in FIGS. 1 to 3, injection lances 1 are distributed in a grid pattern over the area 12 to be built on with a dam and are driven into the ground 4 . Mortar, optionally with a modified silicate-based liquid or other additives, is then pressed into the injection lances 1 . The mortar escaping under pressure through perforations 2 in the injection lance 1 penetrates into the surrounding subsoil. In this way, solidified core areas 5 are formed around the injection lances 1, which can also flow into one another or be mutually interlocked. Concrete slabs 11 are placed on the ends of the injection lances 1 protruding from the ground. These are provided on their underside with a recess 13 which serves to accommodate the ends of the injection lances protruding from the ground. The injection lances are allowed to look out of the ground far enough for the concrete slabs 11 to just sit on the ground surface. The dimensions of the slabs 11 and the grid dimensions for driving the injection lances 1 into the ground are chosen so that the concrete slabs 11 do not touch. The earth 12 for the dam is then heaped onto the concrete slabs 11, in which case the settlements are then reduced, prevented or largely compensated for. MM 1 Blatt Zeichnungen1 sheet of drawings
