Abstract

The invention concerns a method and device for renovating drains which enable connections to domestic connection pipes to be improved. According to the invention pipes made of thermoplastic plastics are introduced into a drain (1). The plastics pipes are then heated in the area covering the connection and this area is subsequently deformed into the domestic connection pipe (3), in the manner of a connection piece, by a telescopic deformation member. During this movement, the deformation member (7) entrains an annular transitional formed part (10) and, as the deformation member moves back, it deposits said part (10) on the interior of the connection piece formed in this way. It is also possible to insert a connection formed part (14) which is sealed with respect to the transitional formed part (10) and the domestic connection (3) in order to improve further the connection to the domestic connection pipe.

Beschreibungdescription
Die Erfindung betrifft ein Verfahren zum Sanieren von Ab¬ wasserkanälen, bei dem thermoplastische Kunststoffröhre un¬ ter Überdeckung einmündender Hausanschlüsse in den Abwas- serkanal eingeführt und an Hausanschlüsse angeschlossen werden, wobei die Position des Überdeckungsbereichs der Hausanschlüsse in den Kunststoffröhren geortet wird, die Kunststoffröhre in dem Überdeckungsbereich mittels Druck und Wärme in der Art eines Stutzens in den Hausanschluß hinein und an dessen Wandung anliegend verformt werden, so¬ wie eine Einrichtung zur Durchführung dieses Verfahrens mit einem in dem Abwasserkanal verfahrbaren Wagen, mit einem Verformkörper, der im Überdeckungsbereich aus dem Abwasser¬ kanal heraus und in den Hausanschluß hinein und wieder zu- rück verfahrbar ist, mit einem Schneidelement und mit einer Erwärmungsvorrichtung.The invention relates to a method for the rehabilitation of sewage ducts, in which thermoplastic pipes are introduced into the sewer under the overlap of house connections opening and connected to house connections, the position of the area of coverage of the house connections being located in the plastic pipes, the plastic pipe in the covering area is deformed by means of pressure and heat in the manner of a connecting piece into the house connection and adjoining its wall, as is a device for carrying out this method with a carriage which can be moved in the sewer, with a deforming body which emerges from the sewage in the covering area ¬ can be moved out and back into the house connection and back again, with a cutting element and with a heating device.
Es sind bereits ein Verfahren und eine Einrichtung bekannt (DE 3 931 616 A1 ) , die zur Sanierung von Abwässerkanälen Verwendung finden. Dabei werden Kunststoffröhre aus einem thermoplastischen Kunststoff in einen Abwasserkanal einge¬ führt. Dann wird in dem so ausgekleideten Abwasserkanal mittels eines Wagens ein Verformkörper vor der Mündung ei¬ nes Hausanschlusses positioniert, wobei diese Mündung zunächst von der Wandung des Kunststoffrohrs überdeckt ist. Der Verformkörper wird dann von der Innenseite des Abwas¬ serkanals her gegen die Wandung des Kunststoffrohrs ge¬ drückt. Der Verformkörper wird aufgeheizt, erwärmt damit das Kunststoffröhr und macht es plastifizierbar. Der Ver- formkörper wird dann in den Hausanschluß hinein bewegt und bildet aus dem die Mündung des Hausanschlusses abdeckenden Bereich des Kunststoffrohrs einen Stutzen. Dieser Stutzen wird an seinem Rand beschnitten. Der Verformkörper wird dann zum Wagen zurückgeführt. Gesonderte Dichtungsmaßnahmen in dem Ringraum zwischen Kunststoffröhr und Hausanschluß sind dabei nicht vorgesehen.A method and a device are already known (DE 3 931 616 A1) which are used for the rehabilitation of sewage canals. Plastic pipes made of a thermoplastic are introduced into a sewer. Then a deforming body is positioned in front of the mouth of a house connection in the sewer lined in this way by means of a carriage, this mouth initially being covered by the wall of the plastic pipe. The deformed body is then pressed against the wall of the plastic pipe from the inside of the sewer. The deformed body is heated, thus heating the plastic tube and making it plasticizable. The deformed body is then moved into the house connection and forms a connection piece from the area of the plastic pipe covering the mouth of the house connection. This neck is trimmed at its edge. The deformable body will then returned to the car. There are no separate sealing measures in the annular space between the plastic pipe and the house connection.
Der Erfindung liegt nun die Aufgabe zugrunde, Verfahren und Einrichtung nach dem Stand der Technik weiter zu verbessern und damit insbesondere die Verbindung zwischen Stutzen und Hausanschlußleitung zu stabilisieren.The invention is based on the object of further improving the method and device according to the prior art and in particular to stabilize the connection between the connecting piece and the house connection line.
Diese Aufgabe wird bei einem Verfahren der eingangs erwähn¬ ten Art dadurch gelöst, daß die Kunststoffröhre vor der Verformung in dem Überdeckungsbereich erwärmt und mit einem Durchgangsloch versehen werden und daß auf den Stutzen in¬ nenseitig ein ringförmiges Übergangsformstück zur Verbin- düng mit dem Hausanschluß plaziert wird. Dabei wird der in den Hausanschluß hineinragende Stutzen besonders gleich¬ mäßig ausgeformt. Zudem wird durch die Einfügung des über- gangsformstückes die Verbindung mit dem Hausanschluß in Plazierung und Abmessungen genau vorgegeben, wodurch insbe- sondere die Sicherheit des Anschlusses und die Dichtigkeit der Verbindung verbessert werden. Dabei kann auf das Über¬ gangsformstück noch ein Anschlußformstück zum Anschluß des Hausanschlusses aufgesetzt werden.This object is achieved in a method of the type mentioned at the outset by heating the plastic tube in the overlap area before the deformation and providing it with a through hole and placing an annular transition fitting on the inside of the connecting piece for connection to the house connection becomes. The nozzle protruding into the house connection is shaped particularly uniformly. In addition, the connection with the house connection is precisely specified in terms of placement and dimensions by inserting the transition fitting, which in particular improves the safety of the connection and the tightness of the connection. In this case, a connection fitting for connecting the house connection can be placed on the transition fitting.
Die gestellte Aufgabe wird zudem bei einer Einrichtung der eingangs erwähnten Art dadurch gelöst, daß die Erwärmungs¬ vorrichtung zu einem Überdeckungsbereich ausrichtbar ange¬ ordnet ist und daß der Verformkörper ein innerhalb des Stutzens an dessen Innenwand absetzbares ringförmiges über- gangsformstück trägt.The object is also achieved in a device of the type mentioned at the outset in that the heating device is arranged such that it can be aligned with an overlap area and in that the deforming body carries an annular transition fitting which can be placed on the inside wall of the connecting piece.
Dabei kann das Übergangsformstück mit einer Verlagerung in Richtung auf den Abwasserkanal entgegenwirkenden Sperrele¬ menten versehen sein, die bei ihrer Einführung in den Stut- zen nur einen vernachlässigbaren Widerstand darstellen, ge¬ gen eine Bewegung in entgegengesetzter Richtung aber sper¬ ren. Das Übergangstück kann radial spreizbar ausgebildet sein. Der Verformkörper kann radial gesteuert verformbar sein. Es kann ein an das Übergangsformstück anschließbares Anschlußformstück zur weiteren Verbesserung der Verbindung zur Hausanschlußleitung vorgesehen sein. Ein solches An¬ schlußformstück kann sich dann an seinem einen Endbereich auf dem Übergangsformstück und an seinem anderen Endbereich auf der Hausanschlußleitung abstützen. Es wird in vielen Fällen zweckmäßig sein, das Übergangsformstück und/oder das Anschlußformstück aus Stahlblech herzustellen. Zweckmäßi¬ gerweise ist mindestens ein Dichtring zwischen übergangs- formstück und Anschlußformstück vorgesehen. Auch zwischen Anschlußformkörper und Hausanschluß ist vorzugsweise ein Dichtring angeordnet.The transition fitting can be provided with a displacement in the direction of the sewer counteracting blocking elements which, when introduced into the supports, represent only negligible resistance, but can block movement in the opposite direction. The transition piece can be designed to be radially expandable. The deformable body can be deformed in a radially controlled manner his. A connection fitting that can be connected to the transition fitting can be provided to further improve the connection to the house connection line. Such a connection fitting can then be supported at its one end region on the transition fitting and at its other end region on the house connection line. In many cases it will be expedient to produce the transition fitting and / or the connection fitting from sheet steel. At least one sealing ring is expediently provided between the transition fitting and the connection fitting. A sealing ring is preferably also arranged between the shaped connection body and the house connection.
Im folgenden Teil der Beschreibung wird eine Ausführungs- form des erfindungsgemäßen Verfahrens sowie der erfindungs¬ gemäßen Einrichtung anhand von Zeichnungen beschrieben.In the following part of the description, an embodiment of the method according to the invention and of the device according to the invention is described with reference to drawings.

Fig. 1 einen Axialschnitt durch einen Abwasserkanal mit Hausanschluß, wobei ein Kunststoffröhr in den Ab¬ wasserkanal eingelegt ist, mit Erwärmungsvorrich¬ tung,1 shows an axial section through a sewer with a house connection, a plastic tube being inserted into the sewer, with a heating device,
Fig. 2 eine der Fig. 1 ähnliche Ansicht, bei der ein Verformkörper vom Innern des Abwasserkanals her in den Hausanschluß eingefahren ist undFig. 2 is a view similar to Fig. 1, in which a deformed body is retracted from the inside of the sewer into the house connection and
Fig. 3 eine den Figuren 1 und 2 ähnliche Darstellung, in welcher der Anschluß für den Hausanschluß fertig ausgebildet dargestellt ist.Fig. 3 is a representation similar to Figures 1 and 2, in which the connection for the house connection is shown fully formed.
In allen Figuren ist ein Abwasserkanal 1 gezeigt, in den zur Sanierung ein Kunststoffröhr 2 aus thermoplastischem Kunststoff eingezogen ist, das in beliebig langen Rohr¬ stücken von einem Kontrollschacht zum anderen reichen kann. In den Abwasserkanal 1 mündet ein Hausanschluß 3. Nach dem Einbau des Kunststoffrohrs 2 überdeckt dieses zunächst die Mündungsöffnung des Hausanschlusses 3.In all of the figures, a sewer 1 is shown, into which a plastic pipe 2 made of thermoplastic material is drawn in for refurbishment, which can extend from one inspection shaft to another in any length of pipe. A house connection 3 opens into sewer 1 Installation of the plastic pipe 2 initially covers the opening of the house connection 3.
Es ist eine Erwärmungsvorrichtung 4 vorgesehen (Fig. 1), die in dem Kunststoffröhr 2 gesteuert verfahrbar ist. Diese Erwärmungsvorrichtung 4 ist mit einer nicht dargestellten Heizung versehen, z.B. mit einer Widerstandsheizung. Die Erwärmungsvorrichtung 4 ist an eine geeignete Energiequelle angeschlossen.A heating device 4 is provided (FIG. 1), which can be moved in a controlled manner in the plastic tube 2. This heating device 4 is provided with a heater, not shown, e.g. with a resistance heater. The heating device 4 is connected to a suitable energy source.
Die Erwärmungsvorrichtung 4 wird in dem Kunststoffröhr 2 in den Mündungsbereich = Überdeckungsbereich des Hausanschlus¬ ses 3 bewegt und erwärmt in diesem Bereich die Wandung des Kunststoffrohrs 2.The heating device 4 is moved in the plastic tube 2 into the mouth area = coverage area of the house connection 3 and heats the wall of the plastic tube 2 in this area.
Es ist ein Wagen 5 vorgesehen (Fig. 2), der ebenfalls in dem Kunststoffröhr 2 gesteuert verfahrbar ist. Dieser Wagen 5 ist mit einem teleskopierbaren Gestänge 6 ausgerüstet, welches relativ zum Wagen 5 schwenkbar und ausfahrbar ist. Das Gestänge 6 trägt an seinem freien Ende einen zylindri¬ schen Verformkörper 7 mit einem gerundeten Kopf 8, auf dem ein kreisförmiges Schneidelement 9 sitzt.A carriage 5 is provided (FIG. 2), which can also be moved in a controlled manner in the plastic tube 2. This carriage 5 is equipped with a telescopic linkage 6 which can be pivoted and extended relative to the carriage 5. The linkage 6 carries at its free end a cylindrical deforming body 7 with a rounded head 8 on which a circular cutting element 9 is seated.
Auf dem Verformkörper 7 sitzt ferner ein Übergangsformstück 10, das ringförmig ausgebildet ist und aus rostfreiem Stahlblech besteht.On the deformed body 7 is also a transition fitting 10, which is annular and made of stainless steel sheet.
Der Wagen 5 ist mit Pratzen 11 ausgestattet, welche ihn in der jeweiligen Arbeitsposition im Abwasserkanal 1 fixieren. Er ist ferner mit einer Fernsehkamera 12 ausgestattet. Dar— über hinaus können Meßgeräte vorgesehen sein, um die Pla¬ zierung des Wagens 5 zu kontrollieren.The carriage 5 is equipped with claws 11 which fix it in the sewer 1 in the respective working position. It is also equipped with a television camera 12. In addition, measuring devices can be provided to control the placement of the carriage 5.
Bei einem Einsatz der Einrichtung wird nach Einbringen des Kunststoffrohrs 2 in den Abwasserkanal 1 ein Übergangsform¬ stück 10 auf den Verformkörper 7 aufgebracht. Dabei wird das Übergangsformstück 10 über den Kopf 8 bis zum Anschla¬ gen an einem Ringbund 17 aufgeschoben. Anschließend wird dann der Wagen 5 mit Hilfe der Fernsehkamera 12 oder ge¬ eigneter Meßgeräte in dem Abwasserkanal 1 plaziert. Das Ge¬ stänge 6 wird auf den Hausanschluß 3 ausgerichtet und aus¬ gefahren. Dabei wird zunächst das Schneidelement 9 in dem von der Erwärmungsvorrichtung 4 bereits erwärmten Über¬ deckungsbereich wirksam, indem es hier ein Durchgangsloch in das Kunststoffröhr 2 schneidet. Beim Vorwärtsbewegen des Verformkörpers 2 wird dann ein in den Hausanschluß 3 hin¬ einreichender Stutzen 13 ausgebildet.When the device is used, a transition molding 10 is applied to the deformable body 7 after the plastic pipe 2 has been introduced into the sewer 1. The transition molding 10 is pushed over the head 8 until it stops on an annular collar 17. Then will then the carriage 5 is placed in the sewer 1 with the aid of the television camera 12 or suitable measuring devices. The rod 6 is aligned with the house connection 3 and extended. First, the cutting element 9 is effective in the overlap area that has already been heated by the heating device 4 by cutting a through hole in the plastic tube 2 here. When the deforming body 2 is moved forward, a connecting piece 13 extending into the house connection 3 is then formed.
Wenn nun der Stutzen 13 bis zu seinem am weitesten vorste¬ henden Ende an die Wandung des Hausanschlusses 3 angelegt ist, wird der Verformkörper 7 zum Wagen 5 hin zurückgezo¬ gen. Dabei werden sogleich an dem Übergangsformstück 10 vorgesehene, nach radial außen hin vorstehende Sperrele¬ mente wirksam. Diese Sperrelemente halten das Übergangs¬ formstück 10 in dem Stutzen 13 entgegen der Rückwärtsbewe¬ gung des Verformköpers 7 fest. Anschließend wird durch den Hausanschluß 3 hindurch ein Anschlußformstück 14 einge- bracht, das sich in Richtung auf den Abwasserkanal 1 ko¬ nisch verjüngt und an seinen beiden Endbereichen außensei¬ tig mit Dichtringen 15,16 versehen ist. Der Dichtring 15 arbeitet dabei mit dem Stutzen 13 und der Dichtring 16 mit dem Hausanschluß 3 zusammen. Das Anschlußformstück 14 ist ein Blechkörper aus rostfreiem Stahl.When the connector 13 is placed against the wall of the house connection 3 up to its most protruding end, the deforming body 7 is pulled back towards the carriage 5. At the same time, radially outwardly projecting locking elements are provided on the transition molding 10 ¬ effective. These locking elements hold the transition fitting 10 in the socket 13 against the backward movement of the deforming body 7. Subsequently, a connection fitting 14 is introduced through the house connection 3, which tapers conically in the direction of the sewer 1 and is provided with sealing rings 15, 16 on the outside at its two end regions. The sealing ring 15 works with the socket 13 and the sealing ring 16 with the house connection 3. The connection fitting 14 is a sheet metal body made of stainless steel.
An das Anschlußformstück 14 kann nun eine Hausanschlußlei¬ tung dicht und zuverlässig angeschlossen werden.A house connection line can now be connected tightly and reliably to the connection fitting 14.
