Abstract

The invention relates to a device and method for making the channel walls watertight around the joint of a subsidiary channel (2) and a main channel having an inliner (1), by applying a viscous jointing compound in the joint area. After hardening, this jointing compound forms watertight wall areas in the joint area. The device consists of a ring-shaped disk with an opening which at least partially overlaps the joint opening in the inliner. The radially outer area (3) of the ring disc is located in the section of the inliner (1) surrounding the joint opening, and can rest against this inliner. Said radially outer area (3) consists of a material which can be joined, in particular welded or glued, to the material of the inliner (1), and verges into a radially inner area (4) of the ring disc which can be integrated into the jointing compound. This radially inner area (4) consists in particular of woven or knitted material, or material composed of laminates or similar. The invention furthermore relates to the use of this device, which is configured as a ring-shaped disc, for making channel walls watertight in the area of the joint of a subsidiary channel and a main channel having an inliner, by means of a viscous jointing compound, which, after hardening, forms watertight wall areas around the joint. The device is also use for producing a watertight connection of the jointing material to the inliner (1) via the ring-shaped disc. The radially outer area (3) of this ring-shaped disc is connected to the inliner, while its radially inner area (4) is integrated into the hardened jointing material.

Description

Vorrichtung und Verfahren zum Abdichten von Kanalwandungen im Bereich des Anschlusses eines Nebenkanals an einen Hauptkanal sowie Verwendung der Vorrichtung Device and method for sealing channel walls in the area of the connection of a secondary channel to a main channel and use of the device

Zum Abdichten von Kanalwandungen im Bereich des Anschlusses eines Nebenkanals an einen Hauptkanal wird häufig so vorgegangen, daß mittels geeigneter Hilfsvorrichtungen mit aushärtbarem Kunststoff getränkte Laminate, Gewebevliese oder dergleichen an der Anschlußstelle positioniert und an die Wandungen von Haupt- und Nebenkanal angedrückt werden. Nach dem Aushärten des Kunststoffs und dem Entfernen der Hilfsvorrichtungen ist eine dichte Anbindung des Abzweigstutzens an den Hauptkanal geschaffen.To seal duct walls in the area of the connection of a secondary duct to a main duct, the procedure is often such that laminates, nonwoven fabrics or the like impregnated with curable plastic are positioned at the connection point by means of suitable auxiliary devices and pressed onto the walls of the main and secondary duct. After the plastic has hardened and the auxiliary devices have been removed, a tight connection of the branch connector to the main duct is created.

Nach anderen, der vorliegenden Erfindung zugrundegelegten Verfahren wird eine viskose Dichtmasse in den Anschlußbereich gepreßt. Dabei kann eine geeignete Schalung verwendet werden, die den Wandungen von Haupt- und Nebenkanal gegenüberliegend positioniert wird und so einen mit der Dichtmasse auszufüllenden Hohlraum bildet. Nach dem Aushärten der Dichtmasse und dem Entfernen der Hilfsvorrichtungen ist mit diesen Verfahren eine dichte Anbindung des Abzweigstutzens an den Hauptkanal geschaffen.According to other methods on which the present invention is based, a viscous sealing compound is pressed into the connection area. A suitable formwork can be used, which is positioned opposite the walls of the main and secondary duct and thus forms a cavity to be filled with the sealing compound. After the sealing compound has hardened and the auxiliary devices have been removed, this method creates a tight connection of the branch connector to the main duct.

Die zuletzt genannten, viskoses Preßmaterial verwendenden Verfahren haben sich bestens bewährt. Ihr Vorteil gegenüber der Kanalsanierung mit aushärtenden Laminaten oder Geweben ist, daß mittels der ausgehärteten, sämtliche Wandunregelmäßigkeiten oder Schadstellen vollständig ausfüllenden Dichtmasse eine nicht nur dichte, sondern auch statisch hoch belastbare Verbindung zwischen dem Haupt- und dem Nebenkanal geschaffen wird, deren Festigkeit insbesondere auf dem intensiven Formschluß zwischen Dichtmasse und angrenzenden Kanalwandteilen beruht. Allerdings hat die Praxis gezeigt, daß die Verpreßtechnik nicht immer zu einer fluiddichten Anbindung der Dichtmasse an die Wandung des Hauptkanals führt, wenn dieser mit einem Inliner versehen ist und keines der möglichen Verpreßmaterialien sich mit dem Inliner zufriedenstellend verkleben läßt. Dies ist insbesondere bei Inlinem aus Polyethylen der Fall. Der Erfindung liegt daher die Aufgabe zugrunde, geeignete Mittel aufzufinden bzw. Maßnahmen zu treffen, um bei mit viskosem Verpreßmaterial arbeitenden Kanalsanierungsverfahren auch dann eine fluiddichte Verbindung zwischen der ausgehärteten Dichtmasse und dem Hauptkanal zu schaffen, wenn dieser mit einem Inliner versehen ist.The last-mentioned processes using viscous molding material have proven themselves very well. Your advantage over sewer renovation with hardening laminates or fabrics is that the hardened sealing compound, which completely fills out all wall irregularities or damaged areas, creates a connection that is not only tight but also has a high static load-bearing capacity, the strength of which is particularly on the intensive positive locking between sealing compound and adjacent duct wall parts. However, practice has shown that the pressing technique does not always lead to a fluid-tight connection of the sealing compound to the wall of the main channel if it is provided with an inliner and none of the possible pressing materials can be satisfactorily glued to the inliner. This is particularly the case with inliners made of polyethylene. The invention is therefore based on the object to find suitable means or to take measures in order to create a fluid-tight connection between the hardened sealing compound and the main duct when the duct renovation method works with viscous grouting material, even if the latter is provided with an inliner.

Diese Aufgabe wird gelöst mit einer die Merkmale des Patentanspruchs 1 aufweisenden Vorrichtung, welche das Verfahren nach Patentanspruch 5 ermöglicht, bei welchem die erfindungsgemäße Vorrichtung entsprechend den Angaben des Patentanspruchs 6 verwendet wird. Zweckmäßige Weiterbildungen der Vorrichtung nach der Erfindung sind in den Patentansprüchen 2, 3 und 4 angegeben.This object is achieved with a device having the features of claim 1, which enables the method according to claim 5, in which the device according to the invention is used in accordance with the details of claim 6. Expedient developments of the device according to the invention are specified in claims 2, 3 and 4.

Zentraler Gedanke der eine Vorrichtung, ein Verfahren und die Verwendung einer Vorrichtung betreffenden Erfindung ist, bei der Abdichtung des Anschlusses eines Nebenkanals an einen mit einem Inliner versehenen Hauptkanal mittels aushärtbarem Verpreßmaterial dieses unter Verwendung einer aus zwei Materialbereichen aufgebauten Ringscheibe an den Inliner anzubinden. Das Material des einen Bereichs der Ringscheibe wird so gewählt, daß es sich leicht mit dem Material des Inliners verschweißen oder verkleben läßt. Dieser radial äußere Bereich trägt den radial inneren Bereich der Ringscheibe, der aus gewebtem, gestricktem oder aus Laminaten oder dergleichen gebildetem Material so ausgelegt ist, daß er sich leicht in das Verpreßmaterial einbinden läßt. Die so aufgebaute Ringscheibe bildet mithin ein Zwischenglied zwischen dem Inliner und der Verpreßmasse, mit dem die dichte Anbindung des Inliners an den Verpreßbereich erreichbar ist.The central idea of the invention, which relates to a device, a method and the use of a device, is to connect the secondary channel to a main channel provided with an inliner by means of hardenable compression material and to connect it to the inliner using an annular disk constructed from two material areas. The material of the one area of the ring disk is selected so that it can be easily welded or glued to the material of the inliner. This radially outer region carries the radially inner region of the annular disc, which is designed from woven, knitted or formed from laminates or the like material in such a way that it can be easily integrated into the compression material. The ring disk constructed in this way thus forms an intermediate member between the inliner and the molding compound, with which the tight connection of the inliner to the pressing area can be achieved.

Nachstehend wird die Erfindung im Rahmen eines Ausführungsbeispiels weiter erläutert.The invention is further explained below in the context of an exemplary embodiment.

Die einzige Figur zeigt einen mit einem Inliner 1 aus Polyethylen ausgekleideten Hauptkanal. An der Einmündung des Nebenkanals 2 in den Hauptkanal weist der Inliner eine Öffnung auf. Rings um diese Öffnung ist die Ringscheibe 3,4 angeordnet. Sie weist einen radial äußeren Bereich 3 aus Polyethylen oder aus einem anderen Material auf, das sich mit dem Polyethylen des Inliners 1 gut verschweißen läßt. Zur Herstellung der Schweißverbindung trägt die Ringscheibe 3,4 in ihrem radial äußeren Bereich 3 Heizleiter 5 , über die die zur Verschweißung erforderliche Wärmeenergie der Verbindungsstelle zuführbar ist.The only figure shows a main duct lined with an inliner 1 made of polyethylene. The inliner has an opening at the junction of the secondary duct 2 into the main duct. The annular disk 3, 4 is arranged around this opening. It has a radially outer region 3 made of polyethylene or of another material which is compatible with the polyethylene of the inliner 1 can be welded. To produce the welded connection, the annular disk 3, 4 carries in its radially outer region 3 heating conductors 5, via which the thermal energy required for welding can be supplied to the connection point.

Anstelle einer Befestigung durch Schweißen kann auch eine andere Verbindung, insbesondere eine Klebeverbindung, zwischen dem Inliner 1 und dem Materialbereich 3 der Ringscheibe 3,4 vorgesehen sein.Instead of an attachment by welding, another connection, in particular an adhesive connection, can also be provided between the inliner 1 and the material region 3 of the annular disk 3, 4.

Im befestigten Zustand liegt die Ringscheibe 3,4 dicht an dem Inliner 1 an und ist der Krümmung des Inliners 1 entsprechend gekrümmt.In the fastened state, the annular disk 3, 4 lies closely against the inliner 1 and is curved in accordance with the curvature of the inliner 1.

In dem radial äußeren Bereich 3 aus Polyethylen ist mit seinem radial äußeren Randbereich ein Ring 4 aus gewebtem, gestrickten oder aus Laminaten oder dgl. gebildetem Material eingebettet. Statt Einbetten kann auch Verkleben oder eine andere Verbindungsart gewählt werden. Es kommt für den radial inneren Materialbereich 4 der Ringscheibe jedes beliebige Material in Frage, das sich gut in die nach dem Befestigen der Ringscheibe eingepreßte Dichtmasse einbinden läßt.In the radially outer region 3 made of polyethylene, with its radially outer edge region, a ring 4 made of woven, knitted or made of laminates or the like is embedded. Instead of embedding, gluing or another type of connection can also be selected. Any material can be used for the radially inner material region 4 of the ring disk that can be easily incorporated into the sealing compound pressed in after the ring disk has been fastened.

Die Figur zeigt die erfindungsgemäße Vorrichtung im am Inliner 1 befestigten Zustand vor dem Einbringen der Dichtmasse. Die vorzugsweise beim Verpressen von einer geeigneten Schalung abgestützte, in der Figur nicht dargestellte Dichtmasse bindet den radial inneren Materialbereich 4 der Ringscheibe 3,4 ein, füllt sämtliche Vertiefungen (Schadstellen 6) im Anschlußbereich aus und bildet statisch hoch belastbare hochfeste Wandbereiche, die sich von der Ringscheibe 3,4 bis zu dem intakten Bereich des Nebenkanals 2 erstrecken. Damit ist eine langlebige, flüssigkeitsdichte Anbindung des Nebenkanals 2 an den mit einem Inliner 1 versehenen Hauptkanal geschaffen. The figure shows the device according to the invention in the state attached to the inliner 1 before the sealing compound is introduced. The sealing compound, which is preferably supported during the pressing by a suitable formwork and is not shown in the figure, binds in the radially inner material area 4 of the annular disk 3, 4, fills all depressions (damaged areas 6) in the connection area and forms structurally highly resilient, high-strength wall areas which differ from of the ring disk 3, 4 extend to the intact area of the secondary channel 2. This creates a long-lasting, liquid-tight connection of the secondary duct 2 to the main duct provided with an inliner 1.
