Description
Die Erfindung betrifft ein Fundament in setzungsempfindlichem Baugrund, insbesondere für einen Damm, das durch Injizieren eines Bindemittels in den Baugrund unter Verwendung von Injektionslanzen hergestellt ist, die rasterförmig verteilt in den Baugrund getrieben sind, im Baugrund verbleiben und mit ihren Enden daraus herausragen, und bei dem der Baugrund mit einer Betonabdeckung versehen ist.The invention relates to a foundation in subsoil susceptible to settlement, in particular for a Dam made by injecting a binder into the subsoil using injection lances is produced, which are driven into the ground in a grid pattern, remain in the ground and with their Ends protrude from it, and in which the building ground is provided with a concrete cover.
Ein derartiges Fundament ist für Trottoirdecken, Betonbetten, Abdeckungen von Erdböschungen und Flußeinbauten bekannt (DE-PS 74 265). Bei diesem bekannten Fundament besteht die Betonabdeckung aus einer durchgehenden Betondecke.Such a foundation is for sidewalk ceilings, concrete beds, covers of earth embankments and River installations known (DE-PS 74 265). In this known foundation, the concrete cover consists of a continuous concrete ceiling.
Für das Eintreiben der Injektionslanzen ist eine Ramme und eine Verpreßmaschine erforderlich. Für die Herstellung der durchgehenden Betondecke sind ebenfalls Maschinen, wie beispielsweise Betenmischer oder Lastkraftwagen erforderlich, zumindest dann, wenn das Fundament größere Abmessungen haben soll, wie das beispielsweise bei einem Damm der Fall ist.A ram and a press machine are required to drive in the injection lances. For the Machines such as beet mixers are also used to manufacture the continuous concrete ceiling or trucks required, at least if the foundation is to have larger dimensions, as is the case with a dam, for example.
Das Injizieren des Baugrundes erfolgt für die Herstellung von Fundamenten insbesondere dann, wenn der Baugrund setzungsempfindlich oder wenig tragfähig ist. Ein solcher Baugrund ist dann auch nicht zum Befahren mit dem vorher erwähnten schweren Gerät geeignet.Injecting the subsoil takes place for the production of foundations in particular when the subsoil is sensitive to settlement or has little load-bearing capacity. Such a subsoil is then also not for Suitable for the aforementioned heavy equipment.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Fundament der eingangs beschriebenen Art zu schaffen, das dem letztgenannten Gesichtspunkt Rechnung trägt und einfacher und schneller herstellbar ist.The invention is therefore based on the object of providing a foundation of the type described at the beginning create that takes the latter aspect into account and is easier and faster to manufacture.
Die Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Betonabdeckung aus einzelnen vorgefertigten Betonplatten besteht, von denen jede an ihrer Unterseite mit einer Ausnehmung zur Aufnahme des Endes einer Injektionslanze versehen ist und die jeweils unter Abstützung auf der Baugrund-Oberfläche auf ein .herausragendes Ende einer Injektionslanze aufgesetzt sind, wobei sich die Betonplatten nicht berühren.The object is achieved in that the concrete cover from individual prefabricated There is concrete slabs, each of which has a recess on its underside for receiving the End of an injection lance is provided and each with support on the subsoil surface on a .the protruding end of an injection lance are attached, whereby the concrete slabs do not touch.
Durch die Verwendung vorgefertigter Betonplatten ist kein schweres Gerät für das Betonieren an der Baustelle mehr erforderlich. Ferner wird dadurch die Möglichkeit eröffnet, bereits verlegte Platten als Arbeitsfundament zum Setzen weiterer Lanzen zu verwenden. Durch die Verwendung vorgefertigter Betonplatten entfällt auch die Notwendigkeit, die Betonabdeckung an der Baustelle vor einer Benutzung als Arbeitsfundament zunächst aushärten zu lassen. Es liegt auf der Hand, daß damit Arbeitszeit gespart wird.By using prefabricated concrete slabs, there is no heavy equipment for concreting on the Construction site more required. This also opens up the possibility of using already laid panels as To use the working foundation for setting further lances. By using pre-made Concrete slabs also eliminates the need to cover the concrete on site prior to use as a working foundation to harden first. It is obvious that this saves working time.
Ein Ausführungsbeispiel der Ei findung wird nachfolgend
anhand der Zeichnungen beschrieben. Es zeigt
F i g. 1 eine Ansicht von oben auf ein Fundament;
Fi g. 2 einen Schnitt H-II durch das Fundament nach Fig.l;
F i g. 3 einen Ausschnitt aus F i g. 2, welche das obere Ende einer Injektionslanze mit aufgesetzter Betonplatte
erkennen läßt.An embodiment of the egg making is described below with reference to the drawings. It shows
F i g. 1 is a top view of a foundation;
Fi g. 2 a section H-II through the foundation according to Fig.l;
F i g. 3 shows an excerpt from FIG. 2, which shows the upper end of an injection lance with a concrete slab attached.
In den Fig.l bis 3 ist die Herstellung eines Fundamentes für einen Damm unter Verwendung einer Vielzahl von Injektionslanzen dargestellt. Die Injek-In Fig.l to 3 is the production of a foundation for a dam using a Variety of injection lances shown. The Inject
JO tionslanzen 1 werden rasterförmig über die mit dem Damm zu bebauende Fläche 4 verteilt in den Baugrund eingetrieben. Dann wird Mörtel gegebenenfalls mit einer auf einem modifizierten Silikat basierenden Flüssigkeit oder anderen Zusatzmitteln in die Injektionslanzen eingedrückt. Auf diese Weise bilden sich verfestigte Kernbereiche 5 um die Injektionslanzen 1 heraus, die auch ineinanderfließen können oder gegenseitig verzahnt sind. Auf die aus dem Baugrund herausschauenden Enden der Injektionslanzen 1 werden Betonplatten 11 aufgesetzt. Diese sind an ihrer Unterseite mit einer Ausnehmung 13 versehen, welche zur Aufnahme der aus dem Baugrund herausschauenden Enden der Injektionslanzen dienen. Man läßt die Injektionslanzen soweit aus dem Baugrund herausschauen, daß die Betonplatten 11 gerade auf der Oberfläche des Baugrundes aufsetzen. Die Abmessungen der Betonplatten 11 bzw. das Rastermaß für das Eintreiben der Injektionslanzen 1 in den Boden ist so gewählt, daß sich die Betonplatten 11 nicht berühren.JO tion lances 1 are raster-shaped over the with the Dam area to be built 4 distributed into the building site. Then mortar is used with if necessary a liquid based on a modified silicate or other additives into the injection lances depressed. In this way, solidified core areas 5 are formed around the injection lances 1 that can also flow into one another or are mutually interlocked. On those from the building site Concrete slabs 11 are placed on the protruding ends of the injection lances 1. These are at yours The underside is provided with a recess 13, which is used to accommodate the The ends of the injection lances are used. The injection lances are allowed to look out of the subsoil, that the concrete slabs 11 just touch the surface of the subsoil. The dimensions the concrete slabs 11 or the grid size for driving the injection lances 1 into the ground is like this chosen so that the concrete slabs 11 do not touch.
Auf die Betonplatten 11 wird dann die Erde 12 für den Damm aufgeschüttet, wobei dann die Setzungen vermindert, verhindert oder weitgehend ausgeglichen werden.On the concrete slabs 11 is then the earth 12 for The embankment is piled up, whereby the subsidence is reduced, prevented or largely compensated for will.
