Abstract
Description
Die Erfindung betrifft einen mehrschichtigen Schlauch zur Innenauskleidung von Rohrleitungen, insbesondere Ab wasserleitungen mit einer Innenfolie und einer Außenfo lie und einem zwischen diesen angeordneten Zweikompo nenten-Harz.The invention relates to a multi-layer hose for the inner lining of pipelines, especially Ab water pipes with an inner foil and an outer fo lie and a two-component arranged between them nenten resin.
Es ist bekannt, zur Renovation nicht begehbarer Rohrlei tungen diese mit einer Innenauskleidung aus einem Harz - ggf. auch unter Verwendung eines Fasermaterials - zu re novieren.It is known for the renovation of inaccessible Rohrlei these with an inner lining made of a resin - possibly also using a fiber material - to the right novices.
Dabei stellt sich das Problem, daß das Harz erst aushärten darf, nach dem der Schlauch in die Rohrleitung eingebracht ist und mittels Aufblasens an der Rohrinnenseite aufliegt. The problem arises that Resin may not harden until after the hose in the Pipeline is introduced and by inflation on the inside of the pipe lies on.
Es ist bekannt, zu diesem Zweck Harz einzusetzen, daß (EP 03 01 204) durch Einbringen von UV- Strahlung oder aber (DE 23 50 976 C2) durch Aufbringen von Wärme ausgehärtet wird.It is known to use resin for this purpose that (EP 03 01 204) by introducing UV Radiation or (DE 23 50 976 C2) through Applying heat is cured.
Bei diesem Verfahren stellt sich jedoch das Problem, daß das Tränken der Fasermatten erst unmittelbar vor dem Einbringen in die Rohrleitung erfolgen kann, also nur an Ort und Stelle.The problem with this method is that the soaking of the fiber mats only immediately before Can be introduced into the pipeline, so only on Spot.
Der Erfindung liegt die Aufgabe zugrunde, einen mehr schichtigen Schlauch zur Innenauskleidung von Rohrlei tungen zu schaffen, der auch fernab von der Baustelle vorbereitet werden kann.The invention has for its object one more layered hose for lining Rohrlei to create solutions that also far from the construction site can be prepared.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß im Raum zwischen der Innenfolie und der Außenfolie eine Vielzahl von kleinen ersten und zweiten Kammern ausge bildet ist, wobei die ersten Kammern mit dem Klebeharz und die zweiten Kammern mit dem Härter gefüllt sind, daß bei Aufbringen von Druck die Wände der Kammern platzen und die Komponenten der Kammern zwischen Innenfolie und Außenfolie austreten und sich miteinander vermischen.According to the invention, this object is achieved in that in the space between the inner film and the outer film Large number of small first and second chambers is formed, the first chambers with the adhesive resin and the second chambers are filled with the hardener that burst the walls of the chambers when pressure is applied and the components of the chambers between the inner film and Exit the outer film and mix together.
Vorzugsweise ist das Zweikomponenten-Harz ein solches, daß nach der Vermischung der Komponenten durch Erwärmung aktiviert, also zur alsbaldigen Aushärtung gebracht wird. Dabei kann vorgesehen sein, daß das Zweikomponen ten-Harz auch nach Aushärtung dauerelastisch ist.The two-component resin is preferably one which that after mixing the components by heating activated, i.e. brought to an immediate hardening becomes. It can be provided that the two-component ten resin is permanently elastic even after curing.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigt die einzige Figur eine Schnitt darstellung eines abgewickelt wiedergegebenen Abschnitts des mehrschichtigen Schlauchs.The invention is described below with reference to a drawing explained. The only figure shows a section representation of a processed reproduced section of the multi-layer hose.
Der mehrschichtige Schlauch besteht aus einer Innenfolie 10 und einer Außenfolie 12 sowie einer Mehrzahl von zwi schen diesen angeordneten ersten Kammern 14 und zweiten Kammern 16. Die ersten Kammern 14 sind mit dem Klebharz K und die zweiten Kammern mit dem Härter H eines Zweikomponenten-Harzes gefüllt.The multi-layer hose consists of an inner film 10 and an outer film 12 and a plurality of first chambers 14 and second chambers 16 arranged between them. The first chambers 14 are filled with the adhesive resin K and the second chambers with the hardener H of a two-component resin.
Die Innenfolie 10 und die Außenfolie 12 sind relativ druckfest. Dagegen sind die Wandungen der Kammern 14 und 16 relativ schwach ausgebildet, so daß sie bei Aufbrin gen eines Drucks unter Freisetzung des Klebharzes K bzw. des Härters H platzen. Nach der automatisch erfolgenden Vermischung des Klebharzes K mit dem Härter H härtet das Zweikomponenten-Harz aus (wobei es jedoch vorzugsweise dauerelastisch bleibt).The inner film 10 and the outer film 12 are relatively pressure-resistant. In contrast, the walls of the chambers 14 and 16 are relatively weak, so that they burst when applied to a pressure releasing the adhesive resin K or the hardener H. After the automatic mixing of the adhesive resin K with the hardener H, the two-component resin hardens (although it preferably remains permanently elastic).
Der hier vorgeschlagene mehrschichtige Schlauch kann fernab von der Baustelle auf Durchmesser und Länge ge fertigt werden. Nach Einbringung - in bekannter Weise in zusammengefaltetem Zustand - und Verschließen der Enden wird Luft in den Schlauch eingebracht, dieser bläst sich auf und legt sich an die Innenwandung der zur renovie renden Rohrleitung an. Durch kurzzeitiges Aufbringen ei nes hohen Drucks platzen die Wände der Kammern 14, 16, die Komponenten treten aus den Kammern aus und vermi schen sich miteinander.The multi-layer hose proposed here can be manufactured far from the construction site in terms of diameter and length. After insertion - in a known manner in the folded state - and closing the ends, air is introduced into the hose, which inflates and lies against the inner wall of the pipeline for renovation. By briefly applying a high pressure, the walls of the chambers 14 , 16 burst, the components emerge from the chambers and mix with one another.
Das Aushärten des Zweikomponenten-Harzes kann durch Ein bringen von erwärmter Luft in den Raum beschleunigt wer den.The two-component resin can be cured by one bring heated air into the room who accelerates the.
