Abstract

The watertight joint is formed at the junction of a mains drainage pipe (4) and household waste pipe (5) in an underground location. A satisfactory joint keeps the surrounding ground area free of unhygienic seepages and the ingress of earth will be prevented thereby preventing the mains drainage pipe from becoming blocked. A lining and mould component (1) is placed into the household waste pipe (5) at an inspection chamber or access point. The lining and a mould component (1) is pushed into the main drainage pipe (4) by means of a hollow pipe tube which is constructed of GRP. The lining and mould component (1) is now pulled back so that the tube section (3) is situated in the entry area of the household waste pipe. A pliable inflatable bag is also placed so that the sides of the bag expand to fill the spaces between the mains drainage pipe and the household waste junction. The lining and mould component is constructed of a fibrous woven material which is impregnated with a self hardening synthetic epoxy resin. The resin will now form the shape of the inside of the pipe connection and thus cause a satisfactory joint to be formed. The inflatable bag will then be removed. Provision is made for the use of liquid or gaseous filling in the bag to be activated through thermal reaction of the epoxy compound. USE - Repair of defective underground pipe joints esp. for domestic drainage points.

Description

Die Erfindung bezieht sich auf eine im Erdreich verlegte Abwasserrohr­ leitung mit einmündendem Hausanschlußkanal.The invention relates to a sewage pipe laid in the ground Pipe with a connecting house duct.

Fernsehuntersuchungen der im Erdreich verlegten Abwasserrohrleitungen haben ergeben, daß in den meisten Fällen die Einmündungen von Hausan­ schlußkanälen in den Hauptkanal nicht sorgfältig ausgeführt wurden. Sofern in der Einmündungszone eine ausreichende Dichtigkeit zwischen dem Hausanschlußkanal und der den Hauptkanal bildenden Abwasserrohrlei­ tung nicht gegen ist, können Abwässer in das Erdreich eindringen und es können auch Flüssigkeiten aus dem Erdreich in die Abwasserrohrlei­ tung einströmen oder es können Teile des Erdreiches in die Abwasser­ rohrleitung eingeschwemmt werden, die zu Verstopfungen führen können.TV surveys of sewage pipes laid in the ground have shown that in most cases the confluence of Hausan end channels in the main channel were not carefully executed. Provided there is sufficient tightness in the confluence zone the house connection channel and the sewage pipe forming the main channel is not against, waste water can penetrate into the soil and liquids from the ground can also enter the sewage pipe flow or parts of the soil can enter the wastewater pipeline that can lead to blockages.

Bei der Auskleidung von im Erdreich verlegten Abwasserrohrleitungen mittels eines aus einem Faserflies gefertigten Auskleideschlauches, der mit einem aushärtbaren Kunstharz getränkt ist, wird von den meisten Auftraggebern nur verlangt, den Hauptkanal und nicht zusätzlich die einmündenden Hausanschlußkanäle zu sanieren.When lining sewage pipes laid in the ground by means of a lining hose made of a fiber fleece, which is impregnated with a hardenable synthetic resin is used by most Clients only require the main channel and not additionally the one to renovate confluent house connection channels.

Aufgrund der Tatsache, daß eine Verklebung des Auskleideschlauches mit dem Altrohr nur bei der Verwendung von Epoxidharzen erreicht werden kann und beim Einsatz von Polyesterharzen zumindest mit einer geringen Schrumpfung gerechnet werden muß, bildet sich bei der Verwendung von Polyesterharzen zwischen dem Altrohr und dem Auskleideschlauch ein, wenn auch minimaler Spalt, in den Abwasser eindringen kann, so daß eine Korrosion nicht verhindert wird.Due to the fact that the lining hose is glued with the old pipe can only be achieved when using epoxy resins  can and with the use of polyester resins at least with a small Shrinkage must be expected when using Polyester resins between the old pipe and the lining hose, although minimal gap, can enter the wastewater, so that corrosion is not prevented.

Der Erfindung liegt die Aufgabe zugrunde, mit konstruktiv einfachen Mitteln die Übergangszone zwischen dem Hausanschlußkanal und dem Haupt­ kanal flüssigkeitsdicht auszubilden.The invention is based, with a structurally simple task Mean the transition zone between the house connection channel and the main to design the channel to be liquid-tight.

Nach der Erfindung wird dies durch ein den Verbindungsbereich zwischen der Abwasserrohrleitung (Hauptkanal) und dem Hausanschlußkanal an der Innenseite abdeckendes, aus einem ein- oder mehrschichtigen Faservlies gefertigtes, mit aushärtbarem Kunstharz getränktes Auskleideformteil erreicht, das auch einem an der freien Stirnfläche und an der Innen­ seite der Abwasserrohrleitung flächenbündig anliegenden Kragen und einem sich in den Hausanschlußkanal erstreckenden, flächenbündig an der Innenseite des Hausanschlußkanals anliegenden Rohrstück besteht und Harzfüllung des Formteils während eines Anpressens des Formteils an die zugeordneten Innenseiten der Rohrleitung und des Kanals ausge­ härtet wird.According to the invention, this is achieved by a connection area between the sewage pipe (main sewer) and the house connection sewer on the Covering on the inside, made of a single or multi-layer fiber fleece Manufactured lining molded part soaked with hardenable synthetic resin achieved that also on the free end face and on the inside side of the sewage pipe, flush-fitting collar and a flush in the house connection channel the inside of the house connection duct adjacent pipe section and resin filling of the molded part during pressing of the molded part to the assigned inside of the pipeline and the duct is hardening.

Das aus einem Kragen und einem Rohrstück bestehende, aus einem Faser­ vlies gefertigte Auskleideformteil kann in seinem Aufbau variiert und als ein- oder mehrschichtiges Faservlies ausgebildet, mit einer innen­ liegenden Folie oder flüssigkeitsundurchlässigen Schicht oder mit einer in den Vlieskörper eingebetteten Sperrschicht versehen werden. Als Fa­ servlies kann ein Polyesternadelfilz oder ein Glasfaservlies eingesetzt werden.That consisting of a collar and a piece of pipe, made of a fiber Nonwoven lining molded part can vary in its structure and designed as a single or multi-layer fiber fleece, with an inside lying film or liquid-impermeable layer or with a barrier layer embedded in the nonwoven body. As a company servlies can use a polyester needle felt or a glass fiber fleece will.

Zum Einbinden des harzgetränken Auskleideformteils in die Übergangs­ zone zwischen dem Hausanschlußkanal und dem Hauptkanal muß durch zu­ sätzliche Mittel der Kragen und das Rohrstück an die zugeordneten Kanal­ bzw. Rohrwandungen angepreßt werden, bis die Aushärtung des Kunstharzes, die als Warm- oder Kaltaushärtung vollzogen werden kann, ausgeführt ist.For integrating the resin-soaked molded part into the transition zone between the house connection duct and the main duct must pass through additional means of the collar and the pipe section to the assigned channel or pipe walls are pressed until the synthetic resin hardens,  which can be carried out as hot or cold curing is.

Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen. Ein Ausführungsbeispiel des Auskleideformteils und das Montageverfah­ ren sind in den Zeichnungen dargestellt, die im folgenden beschrieben werden.Further features of the invention emerge from the subclaims. An embodiment of the lining molding and the assembly process ren are shown in the drawings, which are described below will.

Es zeigt:It shows:

Fig. 4 das in die Abwasserrohrleitung und in den einmündenden Hausan­ schlußkanal eingebundene Auskleideformteil im Schnitt. Fig. 4 in the sewage circuit and in the confluent Hausan circuit channel integrated lining molded part in section.

Das Auskleideformteil 1 setzt sich aus einem Kragen 2 und einem Rohr­ stück 3 zusammen. Es ist aus einem Faservlies gefertigt. Der Kragen wird mit dem Rohrstück durch einen Kleber verbunden.The lining molding 1 is composed of a collar 2 and a tube piece 3 . It is made from a non-woven fabric. The collar is connected to the pipe section with an adhesive.

In der Fig. 2 ist eine den Hauptkanal bildende Abwasserrohrleitung 4 im Schnitt dargestellt, in die ein Hausanschlußkanal 5 einmündet. Zum Einsetzen des Auskleideformteils 1 in die Abwasserrohrleitung 4 und in den Hausanschlußkanal 5 wird durch einen Revisionsschacht direkt am oder im Haus oder aber auch durch eine Putzöffnung im Haus ein so­ genannter Röhrenaal 6 (Glasfiberstab) durch den Hausanschlußkanal 5 bis in die Abwasserrohrleitung 4 geschoben. An dem Röhrenaal wird das Auskleideformteil befestigt und mit seinem Rohrstück 3 in den Haus­ anschlußkanal 5 gezogen. Der Kragen 2 stützt sich in dieser Montagelage des Auskleideformteils 1 an der Stirnfläche 7 des Hausanschlußkanals 5 und an dem benachbarten Teil der Innenfläche 8 der Abwasserrohrleitung 4 ab.In Fig. 2 a sewer pipe 4 forming the main channel is shown in section, into which a house connection channel 5 opens. To insert the lining molded part 1 into the sewage pipe 4 and into the house connection duct 5 , a so-called tubular eel 6 (glass fiber rod) is pushed through the house connection duct 5 into the sewage pipe 4 through a inspection shaft directly on or in the house or also through a cleaning opening in the house. On the tubular eel the molded fitting is attached and with its pipe section 3 in the house connection channel 5 is drawn. The collar 2 is supported in this mounting position of the molded part 1 on the end face 7 of the house connection duct 5 and on the adjacent part of the inner surface 8 of the sewage pipe 4 .

Zum Anpressen des Kragens 2 an die genannten Flächen kann in die Ab­ wasserrohrleitung 4 eine Blase eingesetzt werden, während das Anpressens des Rohrstückes 3 an die Innenfläche des Hausanschlußkanals mittels eines Kalibrierschlauches vorgenommen werden kann. Der Druck wird bis zur Aushärtung des Kunstharzes aufrechterhalten.For pressing the collar 2 to the surfaces mentioned, a bubble can be inserted into the water pipe 4 , while the pressing of the pipe section 3 onto the inner surface of the house connection duct can be carried out by means of a calibration hose. The pressure is maintained until the resin hardens.

Es besteht auch die Möglichkeit, das Auskleideformteil 1 auf eine T- förmig mit einem Druckmittel füllbare Blase 9 zu stülpen und diese Einheit in die Abwasserrohrleitung 4 einzuführen. Das obere Ende der Blase 9 wird dann mit einem Röhrenaal 6 verbunden, der durch den Haus­ anschlußkanal 5 zuvor eingeführt war und anschließend dazu dient, das Auskleideformteil 1 in seine Betriebslage zu ziehen, die in der Fig. 3 aufgezeigt ist. Der Innenraum der T-förmigen Blase 9 wird anschließend mit dem Druckmittel gefüllt, so daß das Auskleideformteil 1 an die zu­ geordneten Flächen des Hausanschlußkanals 5 und der Abwaserrohrleitung 4 gepreßt wird, bis die Aushärtung des Kunstharzes vollzogen ist. An­ schließend wird die T-förmige Blase druckentlastet und mittels des Röhrenaals aus dem Hausanschlußkanal gezogen.There is also the possibility of putting the lining molded part 1 onto a bladder 9 that can be filled with a pressure medium and inserting this unit into the waste water pipeline 4 . The upper end of the bladder 9 is then connected to a tube eel 6 , which was previously introduced through the house connection channel 5 and then serves to pull the molded liner 1 into its operating position, which is shown in FIG. 3. The interior of the T-shaped bladder 9 is then filled with the pressure medium, so that the Auskleideformteil 1 is pressed against the surfaces of the parent to house connection duct 5 and the Abwaserrohrleitung 4 until the curing of the resin is completed. At closing, the T-shaped bladder is relieved of pressure and pulled out of the house connection duct by means of the tubular eel.

Das in die Abwasserrohrleitung und in den einmündenden Hausanschluß­ kanal eingebundene Auskleideformteil 1 ist in der Fig. 4 dargestellt.
