Description

Verfahren zum Isolieren der Außenfläche von Rohren unter Verwendung eines Wickelbandes als Träger für eine bituminöse Masse Die Erfindung geht aus von einem Verfahren zum Isolieren der Außenflächen von Rohren unter Verwendung eines Wickelbandes als Träger für eine bituminöse Masse, wobei das Band mit bituminöser Masse imprägniert und danach das Band mit bituminöser Masse beschichtet wird, wobei die bituminöse Masse mit einem gehärteten Epoxyharz versehen ist.Method for isolating the outer surface of pipes using a wrapping tape as a carrier for a bituminous mass The invention is based on a method of isolating the outer surfaces of pipes using a Wrapping tape as a carrier for a bituminous mass, the tape with bituminous Impregnated mass and then the tape is coated with bituminous mass, wherein the bituminous mass is provided with a hardened epoxy resin.

Die Aufgabe der Erfindung besteht demgegenüber darin, zu erreichen, daß durch das Verfahren Wickelbänder entstehen, die neben großer Festigkeit auch eine große Dehnbarkeit an der Innen- und Außenschicht aufweisen, so daß die durch die Temperaturänderungen hervorgerufenen Längsdehnungen des Rohres am Wickelband elastisch aufgenommen werden, ohne daß das Band reißt und daß andererseits, insbesondere beim Einlegen des Rohres das Erdreich und Beschütten des Rohres mit Erdreich, das Rohr außen nicht verletzt wird, sondern die mechanischen Beanspruchungen an der Außenfläche elastisch 'aufgenommen werden.In contrast, the object of the invention is to achieve that the process creates wrapping tapes, which in addition to great strength have great stretchability on the inner and outer layers, so that the through the temperature changes caused longitudinal expansions of the pipe on the winding tape be absorbed elastically without tearing the tape and that on the other hand, in particular when inserting the pipe the soil and filling the pipe with soil, the The pipe is not damaged on the outside, but the mechanical stresses on the External surface elastically 'are added.

Zur Lösung dieser Aufgabe ist nach einer ersten Lösung die Vereinigung folgender Merkmale vorgeschlagen: a) Das Wickelband wird unmittelbar vordem Aufwickeln auf das Rohr mit der bituminösen Masse, das Epoxyharz ohne Härter enthaltend, imprägniert.For the solution of this task the union is after a first solution The following features are proposed: a) The winding tape is immediately before winding impregnated onto the pipe with the bituminous mass containing epoxy resin without hardener.

b) Das Wickelband wird danach sofort mit der bituminösen Masse, den für Epoxyharz üblichen Aminhärter enthaltend, beschichtet.b) The wrapping tape is then immediately with the bituminous mass, the containing amine hardeners customary for epoxy resin, coated.

In einer zweiten Lösung ist zur Lösung dieser Aufgabe die Vereinigung folgender Merkmale vorgeschlagen: a) Das Wickelband wird unmittelbar vor dem Aufwickeln auf das Rohr mit der bituminösen Masse, den für Epoxyharz üblichen Aminhärter enthaltend, beschichtet.In a second solution, to solve this problem is the union Suggested the following features: a) The winding tape is immediately before winding on the pipe with the bituminous mass containing the amine hardener usual for epoxy resin, coated.

b) Das Wickelband wird danach sofort mit der bituminösenMasse, dasEpoxyharz ohneHärter, enthaltend, beschichtet.b) The wrapping tape is then immediately covered with the bituminous mass, the epoxy resin without hardener, containing, coated.

Durch beide Lösungen wird erreicht, daß entweder in der mittleren Schicht oder in den beiden äußeren Schichten sich zunächst bituminöse Masse plus Kunstharz ohne Härter befindet und in der anderen Schicht, also entweder in den beiden äußeren oder in der mittleren Schicht, zunächst die bituminöse Masse plus Härter ohne Kunstharz befindet. Nur an der Grenze zwischen den drei Schichten bildet sich in der kurzen, hierfür möglichen Zeitspanne eine ganz dünne harte Schicht aus, die dadurch entsteht, daß sich Härter und Epoxyharz verbinden. Ganz in der Mitte und außen und innen ist jedoch eine elastische Schicht. Somit ist durch die genannten dünneren härteren Schichten insgesamt die Festigkeit des Bandes gewährleistet, während durch die -elastischen Schichten die genannten Temperaturänderungen des Rohres elastisch aufgenommen werden, ohne daßRisse im Band entstehen und außen die Beanspruchung des Rohres durch Baraufgeworfenes Gestein elastisch aufgenommen wird, ohne daß Risse in der Binde entstehen.Both solutions achieve that either in the middle First layer or in the two outer layers bituminous mass plus Synthetic resin without hardener is located and in the other layer, i.e. either in the both outer or middle layer, first the bituminous mass plus Hardener is located without synthetic resin. Forms only on the border between the three layers a very thin hard layer develops in the short period of time possible for this, which arises from the fact that hardener and epoxy resin combine. Right in the middle and outside and inside, however, is an elastic layer. Thus, through the said Thinner harder layers while ensuring the overall strength of the tape the said temperature changes of the pipe are elastic due to the elastic layers be absorbed without cracks occurring in the tape and without external stress of the pipe is elastically absorbed by rock thrown up in the bar, without cracks arise in the bandage.
