Abstract

In a pipe connection for large pipes which are to be laid using the rough-pressing method, have no collar, have reinforced walls and consist especially of stoneware, the tips (which abut in front of one another) of the pipes to be connected are reduced in diameter and the reduced tip ends are covered by means of a slip-over collar whose maximum size is less than the external diameter of the pipes to be connected. In addition, at least one profiled ring consisting of a deformable resistant material is inserted as a waterproof connection between the reduced ends of each pipe and the slip-over collar.

Description

Die Erfindung betrifft eine Rohrverbindung für im Vor-The invention relates to a pipe connection for in the pre

preßverfahren zu verlegende muffenlose, wandverstärkte Großrohre, insbesondere aus Steinzeug.sleeve-less, wall-reinforced large pipes to be laid using compression molding, in particular made of stoneware.

In neuerer Zeit werden auch Steinzeugrohre im Vorpreßverfahren mit geschlossener Bauweise für nicht begehbare Abschnitte verlegt.In recent times, vitrified clay pipes are also used in the pre-pressing process closed construction for non-accessible sections.

Aufgabe der Erfindung ist es, für solche muffenlose, im Vorpreßverfahren zu verlegende, wandverstärkte Großrohre eine geeignete Rohrverbindung zu schaffen.The object of the invention is for such sleeveless, in the pre-pressing process To create a suitable pipe connection to be laid, wall-reinforced large pipes.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die voreinanderstoßenden Spitzen der zu verbindenden Rohre im Durchmesser reduziert und die reduzierten Spitzenende mittels einer Oberschiebemanschette abgedeckt sind, deren Größtmaß kleiner als der Außendurchmesser der zu verbindenden Rohre ist, und daß zwischen den reduzierten Enden jedes Rohres und der Oberschiebemanschette mindestens ein Profilring aus einem verformbaren, beständigen Material als wasserdichte Verbindung eingesetzt ist.This object is achieved according to the invention in that the abutting Tips of the pipes to be connected reduced in diameter and the reduced tip end are covered by means of an upper sliding sleeve, the maximum size of which is smaller than the The outer diameter of the pipes to be connected, and that between the reduced Ends of each pipe and the upper sliding sleeve at least one profile ring from one deformable, resistant material is used as a waterproof connection.

Die Spitzen der Steinzeugrohre lassen sich mit diamantbestückten Fräswerkzeugen maßgenau bearbeiten. In die so entstandenen Nuten werden dann die Profil ringe eingelegt, die vorzugsweise aus Gummi bestehen und nach außen weisende Lippen besitzen. Ober das eine Rohrende wird dann eine Manschette aufgeschoben, die aus Stahl oder GFK-Material besteht und den Profil ring so verformt und verpreßt, daß diese Verbindung innen und außen wasserdicht ist. Dann wird das Spitzenende des anderen Rohres gegebenenfalls unter Zwischenlegen eines Abstandshalteringes, der zweckmäßig aus Holz oder einem Spanplattenmaterial besteht, in die Manschette eingeschoben, wobei sich der auf diesem Spitzenende sitzende Profilring entsprechend verformt und auch hier für eine innen und außen wasserdichte Abdichtung sorgt.The tips of the clay pipes can be cut with diamond-tipped milling tools Machining true to size. The profile rings are then inserted into the grooves created in this way, which are preferably made of rubber and have outward-facing lips. Upper A sleeve made of steel or GRP material is then pushed onto one end of the pipe exists and the profile ring is deformed and compressed so that this connection inside and is waterproof on the outside. Then the tip end of the other tube becomes optional with the interposition of a spacer ring, which is expediently made of wood or a Chipboard material is inserted into the sleeve, with the on this top end seated profile ring is deformed accordingly and also here ensures a watertight seal on the inside and outside.

An dem in Vorpreßrichtung vorderen Ende der Manschette wird zwischen diesem und der durch die Reduzierung des Spitzenendes des Rohres gebildeten Stufe ein aus vergleichsweise weichem Material bestehender Dichtring beispielsweise in Form eines Rundschnurringes aus Weichgummi eingesetzt, der gegen Eindringen des Erdreichs beim Vorschub schützt.At the front end of the cuff in the pre-pressing direction is between this and the step formed by reducing the tip end of the tube a sealing ring made of a comparatively soft material, for example in In the form of an O-ring made of soft rubber, which prevents the penetration of the Protects the ground during the advance.

Die Zeichnung zeigt in Fig. 1 zwei voreinanderstoßende, in einer Erdbohrung verlegte muffelose, wandverstärkte Großrohre aus Steinzeug, wobei die Dichtungen im Schnitt gezeichnet sind; und in Fig. 2 einen Schnitt durch den Profilring.The drawing shows in Fig. 1 two abutting one another in an earth borehole laid muffle-free, wall-reinforced large pipes made of stoneware, with the seals are drawn in section; and in Fig. 2 a section through the profile ring.

In Fig. 1 ist mit A die Vorpreßrichtung bezeichnet. 1 bezeichnet das -in Vorpreßrichtung vordere Rohr, das an seinem Spitz'enende, wie bei 2 erkennbar, im Durchmesser reduziert ist. Dieses Reduzieren erfolgt vorzugsweise mit Hilfe eines diamantbestückten Fräswerkzeuges und führt zu einer maßgenauen Bearbeitung. In einer Nut 3 in diesem Spitzenende ist ein Profilring 4 eingesetzt.In Fig. 1, A denotes the pre-pressing direction. 1 denotes that -In the pre-pressing direction, the front tube, which can be seen at its tip end, as shown at 2, is reduced in diameter. This reduction is preferably done with the aid of a diamond-tipped milling tool and leads to dimensionally accurate machining. In a Groove 3 in this tip end, a profile ring 4 is used.

Bei 5 erkennt man eine aus Stahl oder GFK-Material bestehende Manschette, deren Außendurchmesser kleiner als das Größtmaß des Rohres 1 ist.At 5 you can see a cuff made of steel or GRP material, the outer diameter of which is smaller than the largest dimension of the pipe 1.

Man erkennt, daß der Dichtring 4 Lippen 6, 7 aufweist, die sich entsprechend verformen und damit die Verbindung von innen und außen wasserdicht machen.It can be seen that the sealing ring 4 has lips 6, 7, which are accordingly deform and thus make the connection from inside and outside watertight.

An der Vorderkante 8 der Manschette ist zwischen der durch die Durchmesserreduzierung des Rohres 1 am Spitzenende entstandenen Stufe 9 und diese Manschettenende 8 ein Rundschnurring 10 aus Weichgummi eingesetz,t.At the front edge 8 of the cuff is between the diameter reduction of the tube 1 at the tip end created step 9 and this cuff end 8 a O-ring 10 made of soft rubber inserted, t.

Ober einen aus Holz oder Spanplattenmaterial bestehenden Abstandshaltering 11 stößt das Spitzenende des anzuschließenden Rohres 12 gegen das Rohr 1. Auch dieses Rohr 12 ist an seinem Spitzenende entsprechend reduziert und mit,ein,er,Nut 13 versehen, in der eine Profildichtung i4 eingesetzt ist.Using a spacer ring made of wood or chipboard material 11 pushes the tip end of the pipe 12 to be connected against the pipe 1. This too Tube 12 is correspondingly reduced at its tip end and provided with, a, er, groove 13, in which a profile seal i4 is used.

Diese Profildichtung 14 ist im entspannten Zustand in Fig. 2 wiedergegeben. Die Ausbildung dieser Profildichtung bildet mit eine vorteilhafte Weiterbildung der Erfindung.This profile seal 14 is shown in the relaxed state in FIG. The formation of this profile seal forms an advantageous development the invention.

Man e#rkennt, daß auf #einem massiven Ringteil 15 nach außen weisende'Lippen 16, 17 im wesentlich#en gleicher Ausbildung angeordnet sind, die in Vorschubrichtung gemäß dem Pfeil B eine schräge Auflauffläche 18 bzw. 19 aufweisen, während die Rückseite bei 20 und 21 ent,sprechend bogenförmig ausgebildet ist. An der auf der Grundflåche der Rille 3 bzw.One can see that on a massive ring part 15 outwardly pointing lips 16, 17 are arranged in essentially the same configuration, which are in the feed direction according to the arrow B have an inclined run-up surface 18 or 19, while the rear at 20 and 21 accordingly, is formed arcuate accordingly. At the on the ground area the groove 3 resp.

13 aufsitzenden Fläche 22 ist vorzugsweise eine den Halt verbessernde Riefelung 23 vorgesehen.13 seated surface 22 is preferably a support improving Grooving 23 is provided.
