Description

Herstellung von dichten Verbindu#gen im iteliningverfakihren.Production of tight connections in the itelining process.

seines der wesentlichen IUlerkmale im#Reliningverfahren istodas Einziehen ein#es Kunststoffrohres in die liegende (zu sanierende) Leitung.One of the essential features of the relining process is the feeding a # es plastic pipe in the lying pipe (to be rehabilitated).

Die Herstellung der Verbindung vom eingezogenen zum liegenden Rohr erfolgt bei Nennweiten bis zu ca. 200 mm durch Aufbördeln eines Endes des Kunststoffrohres,wobei bundähnliche Kanten entstehen,welche in die Flanschen des liegenden Rohres eingespannt werden.Establishing the connection from the drawn-in to the lying pipe takes place with nominal widths up to approx. 200 mm by flanging one end of the plastic pipe, whereby collar-like edges are created, which are clamped into the flanges of the lying pipe will.

Bei Rohren größerer Nennweiten ist die Anfertigung von Vorschweißbunden erforderlich,die mittels Schweißmaschine angeschweißt werden.Für dieses Verschweißen ist ein Arbeitsraum -erfcrderlich,der es unmöglich macht ,das eingezogene mit dem liegedden Rohr ohne bewegliche Zwischenstücke dichtend und belastungsfrei zu schließen. Wenn dieser Arbeitsraum nicht geschlossen wird, kann der Spaltraum nicht einwandfrei verfüllt werden und das Kunststoffrohr kann dann nicht den aufgenommenen Innendruck an das liegende Rohr weitergeben.Das Kunststoffrohr ist auch den Belastungen von außen ausgesetzt.For pipes with larger nominal widths, welding necks are required required, which are welded on by means of a welding machine. For this welding A work space is required, which makes it impossible to use the to close the lying pipe in a sealing and stress-free manner without moving intermediate pieces. If this working space is not closed, the gap space cannot function properly be filled and the plastic pipe can then not absorb the internal pressure to the lying pipe. The plastic pipe is also the loads of exposed outside.

Bisher hat man im Reliningverfahren da-s Innenrohr aus dem liegenden Rohr austreten lassen, wie z.B.Until now, the relining process has resulted in the inner tube from the horizontal Let the pipe come out, e.g.

im Modell Fulda. Selbst bei kleinen enneiten ist bei Gasmedien durch tSbördeln keine Dauerdichtung zu erzielen.in the Fulda model. Even with small enneiten is through with gas media tS flaring does not achieve a permanent seal.

Ein speziell angefertigter Vorscheißbund,der mittels Spiegelschweißung angebracht wird, läßt sich einwandfrei und dauerdicht in eine Flanschverbindung einbauen. Dadurch wird erreicht: 1) Das Innenrohr wird unabhängig vom liegenden (Außen) Rohr dicht eingebunden 2) Das Außenrohr wird in keiner Weise verändert,es wird an keiner Stelle unterbrochen und bleibt somit als Aufnahmekörper von Innen-und Außenbelastungen erhalten.A specially made apron collar, which is welded using mirror welding is attached, can be properly and permanently sealed in a flange connection build in. This achieves: 1) The inner tube becomes independent of the horizontal one (Outer) pipe tightly integrated 2) The outer pipe is not changed in any way, it is not interrupted at any point and thus remains as a receiving body from the inside and outside Received external pollution.

3) Da@ die Spaltinjektion mit dem erforderlichen Druck erfolgen kann,um hohlfrei zu verfüllen. 3) Because @ the gap injection can be done with the necessary pressure to to be filled hollow-free.

Wird der Spaltraum nicht hohlfrei verfüllt,entsteht keine genügend große Haftreibung und das Innenrohr (das eingezogene Rohr) findet unter Belastung keine entlastende Anlehnung, es kommt axial und radial ins Wandern und dadurch verliert das Reliningsystem seine #irkung.Das Plastikrohr erleidet vorzeitig zierkstoffschäden. If the gap is not filled without cavities, there will not be enough great static friction and the inner tube (the drawn-in tube) takes place under load no relieving support, it comes axially and radially into wandering and thus loses The railing system has its effect. The plastic pipe suffers premature damage to the decorative material.

Die beigefügten Zeichnungen zeigen die Ausführung der Herstellung von dichten Verbindungen. The attached drawings show the execution of the manufacture of tight connections.
