Abstract

The system is used when a structure such as a large pipeline or culvert is pressed horizontally into a bank of earth. The cross-section of ground is excavated under protection of the overhanging lip (5) of the pipe. The system maintains the sliding plane directly below its floor. In the courses of the through-pressing process, one or more rows of sliding plates (2) are laid down to form sliding tracks in front of the slightly raised base of the structure (4) base slab (1). The sliding plates are selectively interconnected, and back- anchored, individually or collectively, against the direction of thrust. Lengths of material (3) with low friction resistance may be located on the bottom of the base slab. This readily permits controlled sliding for the structure.

Description

Verfahren zur Erhaltung der Gleitebene Procedure for maintaining the slip plane

direkt unter der Sohle eines im Durchpreßverfahren einzubringenden Bauwerks Die Erfindung betrifft ein Verfahren zur Erhaltung der Gleitebene direkt unter der Sohle eines im Durchpreßverfahren einzubringenden Bauwerks. directly under the sole of a press-through process Building The invention relates to a method for maintaining the slip plane directly under the base of a structure to be inserted using the press-through method.

Es ist bekannt, ein zu durchpressendes Bauwerk mit seiner Stirnfläche in den Boden einzupressen und den zu durchdringenden Bodenquerschnitt im Schutze des Bauwerks abzutragen, wobei die Sohlplatte des Bauwerks auf dem vor der Stirnfläche in kurzen Abständen vorauseilend planierten Boden gleitet. Dabei muß die Reibung zwischen Bauwerks sohle und Boden geringer sein als die Scherfestigkeit des Bodens selbst, da sonst der Boden in Lagen verschiedener Mächtigkeit vom Bauwerk mitgerissen wird und sich dabei Gleitfugen in unkontrollierbar verlaufenden Höhenlagen im Boden einstellen und damit eine Steuerung des durchzupressenden Bauwerks unmöglich wird.It is known to press through a structure with its end face to be pressed into the ground and the ground cross-section to be penetrated in the protection of the structure to be removed, with the base plate of the structure on the front of the face slides leveled ground ahead of you at short intervals. There must be friction between the building floor and the ground must be less than the shear strength of the ground itself, as otherwise the soil would be carried away by the structure in layers of different thicknesses and thereby sliding joints at uncontrollable heights in the ground adjust and control of the structure to be pressed through becomes impossible.

Auf Böden mit geringer Scherfestigkeit ist deshalb ein kontrolliertes Gleiten des Bauwerks mit bekannten Verfahren nicht mehr möglich.On soils with low shear strength is therefore a controlled Sliding of the structure is no longer possible with known methods.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Erhaltung der Gleitebene direkt unter der Bauwerks sohle zu erbringen. Diese Aufgabe wird mit den im kennzeichnenden Teil der Ansprüche 1-4 angegebenen Merkmalen gelöst.The invention is therefore based on the object of a method for To maintain the slip plane directly under the building base. This task is achieved with the features specified in the characterizing part of claims 1-4.

Mit dem Verfahren nach der Erfindung erreicht man den Vorteil, daß trotz der räumlichen Behinderung in Durchpreßrichtung unter dem Bauwerk zusammenhängende Gleitbahnen mit geringer Gleitreibung eingebracht werden können. Durch Verlegen der Gleitplatten höher oder tiefer als die Unterkante der Bauwerks sohle kann die Höhenlage und eine unerwünschte Drehung um die Längsachse des darauf zu verschiebenden Bauwers gesteuert werden.With the method according to the invention one achieves the advantage that contiguous under the structure in spite of the spatial obstruction in the direction of pressure Slideways can be introduced with low sliding friction. By embarrassing the sliding plates can be higher or lower than the lower edge of the base of the structure Altitude and an undesirable rotation about the longitudinal axis of the to be moved on it Bauwers are controlled.

Die Erfindung ist nachstehend anhand der Zeichnung beschrieben.The invention is described below with reference to the drawing.

Es zeigen: Fig. 1 einen Schnitt durch das teilweise in den Boden eingepreßte Bauwerk, Fig. 2 eine Untersicht des Bauwerks.They show: FIG. 1 a section through the partially pressed into the ground Building, Fig. 2 is a bottom view of the building.

Das Bauwerk 4 wird mittels der Schubpressen 5 auf den zu Gleitbahnen aneinandergereihten Gleitplatten 2 in den zu durchfahrenden Erddamm 6 eingepreßt. Am vorderen Ende der dort leicht hochgezogenen Bodenplatte 1 werden laufend Gleitplatten 2 angeschlossen und gegebenenfalls mit den bereits verlegten Gleitplatten 2 verbunden.The structure 4 is by means of the push presses 5 on the slideways Lined up sliding plates 2 pressed into the earth dam 6 to be driven through. At the front end of the base plate 1, which is slightly pulled up there, sliding plates are continuously 2 and, if necessary, connected to the sliding plates 2 that have already been laid.

Aus Fig. 2 ist die Anordnung der auf der Sohle der Bodenplatte 1 angeordneten Materialbahnen 3 mit geringem Reibwiderstand zu ersehen.From Fig. 2 the arrangement of the arranged on the sole of the base plate 1 is Material webs 3 can be seen with low frictional resistance.
