KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

: Den Gegenstand der Erfindung bildet eine Neuerung an dem unter anderem durch die Patentschrift 74265 bekannt gewordenen Verfahren zur Herstellung von Grundbau, bei welchem zur Befestigung von für den Grundbau dienenden Rohren flüssiger Cementbrei in diese eingeführt und durch seitliche Oeffnungen in den umgebenden Boden ausgespritzt wird. Die Neuerung besteht darin, dafs dem eingeprefsten Cementbrei das tiefere Eindringen in den Boden dadurch ermöglicht wird, dafs, wie in beiliegender Zeichnung dargestellt ist, das Grundbaurohr a, welches im Uebrigen beliebig angeordnet sein kann, mit seitlichen Stacheln s versehen ist, welche während der Eindrehung des Rohres Furchen in den Boden ziehen, die sofort durch unter Hochdruck eingepumpten, an der Wurzel der Stacheln durch die Seitenöffnungen I I austretenden Cementbrei ausgefüllt werden. Dadurch wird erreicht, dafs sich der Cementbrei mit dem Boden vermischt, ihn inkrustirt und festigt. Das ein-1 gebohrte1 Grundbaurohr empfängt nach Erhärtung des Cementbreies bedeutende Standfestigkeit und wird befähigt, je nach der Tiefe der Einbohrung und nach dem Umkreis, den die Stacheln durchfurcht haben, einen entsprechenden Oberbau zu tragen, denn der ganze solchergestalt durchfurchte Boden wird in eine compacte Betonmasse verwandelt.: The subject of the invention is an innovation in the method for the production of foundation structures, which has become known, inter alia, from the patent specification 74265, in which liquid cement paste is introduced into the foundation construction pipes and injected into the surrounding soil through lateral openings. The innovation consists in the fact that the pressed-in cement paste is able to penetrate deeper into the ground by the fact that, as shown in the accompanying drawing, the basic construction pipe a, which can otherwise be arranged as desired, is provided with lateral spikes s , which during the Turning the pipe into the ground, which is immediately filled by cement paste that is pumped in under high pressure and exiting at the roots of the spines through the side openings II. This ensures that the cement paste mixes with the soil, encrusts it and strengthens it. The switch 1 drilled 1 Basic Baur ear receives after hardening of the Cementbreies significant stability and is capable, depending on the depth of the single bore and after the radius, the spines have fear to bear an appropriate superstructure, for the whole of such shape furrowed soil in a compact concrete mass transformed.

Die bggehriebeße Festigung des Bodens,The solid consolidation of the soil,

falls es blos hierauf ankommt, kann aber auch mittels. desselben Verfahrens erreicht werden, ,ohne dafs es nöthig ist, das Grundbaurohr im Boden zu belassen, indem man nämlich den' Cementbrei nicht schon beim Eindrehen des Rohres in den Boden, sondern erst beim Herausdrehen einführt.but if this is the only thing that matters, it can also be by means of. the same procedure can be achieved, , without it being necessary to leave the foundation pipe in the ground, namely by Cement paste not when the pipe is screwed into the ground, but only when it is unscrewed introduces.

In dem ersten Falle, wenn das Rohr im. Boden verbleiben soll, wird zweckmäfsig ein unten geschlossenes Rohr verwendet, dessen' untere Spitze einen festen Bohrer bildet. Soll dagegen. das Rohr wieder herausgedreht werden, so kann auch ein unten offenes Rohr benutzt werden; alsdann mufs der erbohrte Kern mittels eines eingeschobenen Innenrohres mit Bohrlöffel herausgehoben und sodann der Cementbrei während des Herausdrehens eingeprefst werden.In the first case, when the pipe is in. Soil is to remain, is expediently a tube closed at the bottom is used, the lower tip of which forms a solid drill. Intended to against it. the pipe can be unscrewed again, a pipe that is open at the bottom can also be used will; then the drilled core has to be included by means of an inserted inner tube The drill spoon is lifted out and the cement paste is then pressed in while it is being unscrewed will.

In beiden Fällen kann, um den Austritt des. Cementbreies aus den Oeffnungen / zu regeln, in dem Rohre r auch ein verschiebbares Innenrohr angebracht werden, durch dessen Verschiebung die Oeffnungen / beliebig verschlossen oder geöffnet werden können.In both cases the outlet and a displaceable inner tube through its displacement can, of. Cementbreies to settle out of the openings /, r in the pipes are mounted, the openings / variable closed or can be opened.
