Description
Die Erfindung betrifft ein Verfahren zum Verlegen von thermoplastischen Kunststoffrohren im Relining-Verfahren, wobei das Kunststoffrohr in eine abzudichtende Rohrleitung durch eine Öffnung eingeschoben wird.The invention relates to a method for laying thermoplastic pipes in Relining process, where the plastic tube in one Pipe to be sealed through an opening is inserted.
Bei der Sanierung undichter Gas-, Wasser- und Kanalleitungen werden in zunehmendem Maße thermoplastische Kunststoffrohre im sogenannten Relining-Verfahren eingesetzt. Ein derartiges Verfahren ist z. B. durch das deutsche Gebrauchsmuster 69 42 876 bekannt. Um die lichte Weite der Rohrleitung, die zu sanieren ist, möglichst groß zu halten, werden Rohre eingesetzt, die dünnwandig sind.When refurbishing leaking gas, water and Sewer lines are increasing thermoplastic pipes in the so-called Relining procedure used. Such a thing The procedure is e.g. B. by the German utility model 69 42 876 known. To the clear width of the Pipeline that needs to be rehabilitated as large as possible hold, tubes are used that are thin-walled.
Der Nachteil dabei ist, daß sich die dünnwandigen Rohre nur mit großen Biegeradien in die zu sanierende, d. h. abzudichtende Rohrleitung einziehen lassen. Bei tiefliegenden Leitungen sind daher lange Baugruben zum Einbringen der Kunststoffrohre erforderlich. Anderenfalls ist der Biegeradius zu eng und das Kunststoffrohr beult im gebogenen Bereich ein oder knickt sogar ab. Hierbei treten Beschädigungen auf, die eine weitere Verwendung der Rohre unmöglich machen.The disadvantage is that the thin-walled Pipes only with large bending radii into the d. H. Have the pipeline to be sealed drawn in. At deep pipes are therefore long construction pits It is necessary to insert the plastic pipes. Otherwise the bending radius is too narrow and that Plastic pipe bulges in the bent area or even kinks. Damage occurs here, which further use of the pipes is impossible do.
Aufgabe der Erfindung ist es daher, ein Verfahren anzugeben, mit dem die thermoplastischen Kunststoffrohre auch mit engem Biegeradius, also unter Anwendung kleiner Baugrubenöffnungen, in die Rohrleitung eingebracht werden können.The object of the invention is therefore a method specify with which the thermoplastic Plastic pipes also with a narrow bending radius, i.e. under Use of small pit openings in which Pipeline can be introduced.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß das Kunststoffrohr vor dem Einführen in die Leitung abgeflacht, gebogen und wieder gerundet wird, wobei das Kunststoffrohr unmittelbar vor dem Abflachen und ggf. dem Runden erwärmt wird.This object is achieved in that the plastic pipe before inserting it into the pipe is flattened, bent and rounded again, whereby the plastic pipe immediately before flattening and if necessary, the round is heated.
Die erfindungsgemäße Lösung nutzt zum einen die Flexibilität der Rohrwand aus und unterstützt zum anderen die Verformung durch eine Erwärmung. Beim kontinuierlichen Einziehen oder -schieben wird das Rohr erwärmt, in einer Vorrichtung abgeflacht, gebogen und nach dem Passieren der Biegung, ggf. nach erneuter Erwärmung, wieder gerundet. Hierbei erfolgt das Einbringen des Rohres in die Baugrube oder den Kanalschacht nach dem Biegevorgang, und das Runden erfolgt kurz vor dem Einführen des Rohres in die Leitung.The solution according to the invention uses the one Flexibility of the pipe wall and supports others the deformation caused by heating. At the that will be continuous pulling or pushing Pipe warmed, flattened in a device, bent and after passing the bend, if necessary after renewed Warming, rounded again. This is done here Introducing the pipe into the construction pit or Manhole after the bending process, and the rounding takes place shortly before the pipe is inserted into the Management.
Dieses Verfahren ermöglicht es, bei Kanälen die vorhandenen Schächte auszunutzen. Es ist also nicht erforderlich, Tiefbauarbeiten zur Herstellung langer Baugruben auszuführen, wie sie zum Einbringen der Rohre notwendig sind, um große Biegeradien einzuhalten. Durch die Ausnutzung der Flexibilität der Rohrwand und deren Erwärmung treten keine Beschädigungen auf.This procedure makes it possible for channels to use existing shafts. So it's not required civil engineering work to produce long Execute excavation pits as they are used to bring in the Pipes are necessary to accommodate large bending radii to adhere to. By taking advantage of the flexibility of The pipe wall and its heating do not occur Damage.
Indem bei dem erfindungsgemäßen Verfahren nur kleine Baugruben notwendig sind oder die vorhandenen Kanalschächte ausgenutzt werden können, ist damit eine Sanierung von Gas-, Wasser- und Kanalleitungen auch in Straßen und Kreuzungen mit hohem Verkehrsaufkommen möglich.By only small in the method according to the invention Excavation pits are necessary or the existing manholes can be exploited, is a renovation of Gas, water and sewer lines also in streets and Intersections with high traffic possible.
