Abstract

In the method, plastic or the like is applied in existing pipelines by means of a suspended nozzle body. A nozzle is set in rotation by the discharge of a gas (e.g. air) under pressure. The nozzle body is centred in the inner pipe by the rotary movement. The nozzle body has no contact with the inside of the pipe. The surface of the inner lining is finished via a smoothing and drawing ring. The coating of pipe branches is possible by the freely suspended nozzle body.

Description

Die vorliegende Erfindung betrifft das Beschichten von installierten Rohrleitungsnetzen, insbesondere industrielle oder kommunale Abwassernetze, ohne einzelne Rohrstücke aus dem Netz zu demontieren. Dies erfolgt mittels einer durch Gasdruck angetriebe­ nen, rotierenden Produktdüse, mit der die Innenseite des Rohres mit Kunststoff oder dgl. versehen werden kann.The present invention relates to the coating of installed pipeline networks, especially industrial or municipal sewage networks, without individual pipe sections disassemble from the network. This is done by means of a gas pressure driven NEN, rotating product nozzle with which the inside of the tube with plastic or Like. Can be provided.

Zahlreiche Abwasserleitungen, die zumeist als Beton- oder Steinzeugrohr verlegt wurden, sind sanierungsbedürftig. Die Sanierung der Rohrnetze werden zur Minimie­ rung der Leckageverluste und zur Verhinderung der Bodenverunreinigung durchge­ führt. Besonders die Reparatur von Abwassernetzen, in denen aggressive Medien ge­ fördert werden, erfolgen nach Stand der Technik so, daß die defekten Rohrleitungs­ stücke freigelegt werden und die einzelnen Leitungen ausgetauscht werden müssen.Numerous sewage pipes, mostly laid as concrete or stoneware pipes are in need of renovation. The renovation of the pipe networks are minimized leakage loss and to prevent soil contamination leads. Especially the repair of sewage networks in which aggressive media are promoted according to the prior art so that the defective pipeline pieces are exposed and the individual lines must be replaced.

Dieser Vorgang ist sehr kostenintensiv.This process is very expensive.

Diese Problematik wird nach der Erfindung dadurch gelöst, daß ein frei schwebender Düsenkörper (Abb. 1) auf einer Seite in den Rohrleitungsabschnitt (1), der beschichtet werden soll, eingebracht wird. Von der anderen Seite wird die Gasdruck- (7) und Be­ schichtungsprodukt-(8)Leitung durchgeschoben und am Düsenkörper befestigt.This problem is solved according to the invention in that a free-floating nozzle body ( Fig. 1) is introduced on one side into the pipe section ( 1 ) which is to be coated. From the other side, the gas pressure ( 7 ) and loading coating ( 8 ) line is pushed through and fastened to the nozzle body.

Um eine Hin- und Herbewegung des Düsenkörpers durchzuführen, wird auf der gegen­ überliegenden Seite eine Steuerleine (6) befestigt.To perform a back and forth movement of the nozzle body, a control line ( 6 ) is attached to the opposite side.

Durch Aufgabe von Gasdruck beginnt die Gasdüse (2) zu rotieren und sich im Rohr zu zentrieren, so daß der Düsenkörper keine Berührung zur Rohrinnenseite hat. Die Produktdüse (3) rotiert mit der Gasdüse. Der Impuls der Gasdruckdüse wirkt der Be­ schichtungsvorrichtung entgegen, damit wird eine Spannkraft zwischen der Gasdruck- und Beschichtungsprodukt-Leitung hergestellt. Der durch Erwärmung fließfähig ge­ machte Kunststoff wird auf die Innenseite des Rohres über die Produktdüse aufge­ bracht. Um die Qualität des Auftragens zu verbessern, sind nach der Produktdüse ein Glätt- (5) und Ziehring (4) angeordnet. Eine ggf. notwendige Nachbearbeitung der be­ schichteten Oberflächen kann mit geeignetem, aufsetzbarem Werkzeug durchgeführt werden.By applying gas pressure, the gas nozzle ( 2 ) begins to rotate and center itself in the pipe so that the nozzle body has no contact with the inside of the pipe. The product nozzle ( 3 ) rotates with the gas nozzle. The impulse of the gas pressure nozzle counteracts the coating device, so that a tension force is established between the gas pressure and coating product line. The plastic, which is made flowable by heating, is applied to the inside of the tube via the product nozzle. In order to improve the quality of the application, a smoothing ring ( 5 ) and drawing ring ( 4 ) are arranged after the product nozzle. Any necessary reworking of the coated surfaces can be carried out with a suitable, attachable tool.

An Kunststoff oder dgl. Materialien kommen für die Innenauskleidung alle geeigneten bzw. gebräuchlichen Kunststoffe mit der erforderlichen Resistenz gegenüber den vor­ kommenden aggressiven Substanzen, wie Hart- und Weich-PVC sowie entsprechende Kunstharze inklusive Kunstharzbeton und dergleichen Gemische in Betracht.Plastic or similar materials come with all suitable for the inner lining or common plastics with the required resistance to the before coming aggressive substances, such as hard and soft PVC as well as corresponding Synthetic resins including synthetic resin concrete and the like mixtures into consideration.

Zur Reinigung des Rohres kann vor der Beschichtung über die Produktdüse Druck­ wasser geführt werden.To clean the pipe, pressure can be applied via the product nozzle before coating water.

Die Beschichtung von Rohrverzweigungen ist durch den frei schwebenden Düsen­ körper gewährleistet (Abb. 2) und kann z. B. in der beschriebenen Reihenfolge durch­ geführt werden:The coating of pipe branches is guaranteed by the free-floating nozzle body ( Fig. 2). B. be carried out in the order described:

  • - Beschichtung der gesamten Rohrstrecke A,- coating of the entire pipe section A,
  • - Beschichtung der Bogenstücke B + C.- Coating of the bow pieces B + C.
