Abstract
Description
Einstellbare, hydraulische Aufweitvorrichtung zum Sanieren bzw. Erneuern von unterirdischen Abwasser kanälen, durch aufweiten mit möglichst kleinem Ringraum, unter gleichzeitigen Nachführen von Spezialkurzrohren, über vorhandene Schachtbauwerke oder Baugruben.Adjustable hydraulic expansion device for Rehabilitation or renewal of underground wastewater channels, by expanding with the smallest possible Annulus, with simultaneous tracking of Special short pipes, over existing shaft structures or construction pits.
Die Aufweitvorrichtung wird hierbei von einer über Funk, vom Einzugschacht aus gesteuerten Seilwinde taktweise (aufweiten, zusammenfahren, vorziehen) über eine Umlenkrolle im Endschacht vorgezogen Fig. 3. Die Spezialkurzrohre werden gleichzeitig, mit dem Vorziehen der Aufweitvorrichtung mit einer hydrau lischen Nachführeinrichtung, vom Einzugschacht aus nachgeschoben.The expanding device is pulled forward by a radio winch, controlled from the feed chute in cycles (expanding, pulling together, pulling forward) via a deflection roller in the end shaft Fig. 3 pushed out.
Es ist bekannt, daß es bereits Aufweitvorrichtungen zum Sanieren, von unterirdischen Abwasserkanälen gibt.It is known that there are already expanding devices for the rehabilitation of underground sewers gives.

Die derzeitigen Aufweitvorrichtungen lassen sich nicht auf die unterschiedlichen Rohrdurchmesser der neu einzubauenden Rohre einstellen.The current expanders can be not on the different pipe diameters of the new pipes to be installed.
Das heißt um einen möglichst kleinen Ringraum zwischen verdrängten Material und neu eingebauten Rohr zu erhalten, müßte für jeden Rohrdurchmesser eine Aufweitvorrichtung vorhanden sein. That means around the smallest possible annulus between displaced material and newly installed Obtaining pipe would have to be for every pipe diameter an expanding device may be present.
Die bisherige Arbeitsweise hat gezeigt, das ein zu großer Ringraum keine stabile Lage der neu einge bauten Rohre gewährleistet, so das der entstandene Ringraum kosten- und zeitaufwendig mit Dämmer ver füllt werden muß.The previous way of working has shown that one too large annulus no stable location of the newly turned on built pipes guaranteed, so that the resulting Annulus ver and costly with twilight ver must be filled.
Der Erfindung liegt die Aufgabe zu Grunde, daß die hydraulische Aufweitvorrichtung, durch auswechseln von Basis und Gehäuseteilen auf den erforderlichen Rohrdurchmesser eingestellt werden kann.The invention is based on the object that hydraulic expansion device, by replacing base and housing parts to the required Pipe diameter can be adjusted.
Durch die Einstellbarkeit der hydraulischen Auf weitvorrichtung wird erreicht, daß der Ringraum zwischen verdrängten Material und den neu einge bauten Rohren, so klein wie möglich bleibt, damit eine stabile Lage der eingebauten Rohre erreicht wird.Due to the adjustability of the hydraulic on Wide device is achieved that the annulus between repressed material and the newly inserted built pipes, as small as possible so that achieved a stable position of the installed pipes becomes.
Die Vorteile der einstellbaren hydraulischen Auf weitvorrichtung liegen darin.The advantages of adjustable hydraulic on there are wide devices.
- a) Es braucht nicht für jeden Rohrdurchmesser eine passende Aufweitvorrichtung hergestellt werden, es werden hierdurch erhebliche Herstellungs kosten eingespart.a) You don't need one for every pipe diameter suitable expanding device are manufactured, this will result in significant manufacturing cost savings.
- b) Durch die Einstellbarkeit wird ein kleinst mög licher Ringraum erreicht, der nicht kosten- und zeitaufwendig verdämmt werden muß.b) The adjustability makes the smallest possible Licher annulus reached that is not cost and time-consuming must be insulated.
- c) Es wird durch die Einstellbarkeit verhindert, das sich durch einen zu großen Ringraum Hohl räume bilden können, die durch zurückfallendes Erdreich nicht mehr verdämmt werden können.c) The adjustability prevents which is characterized by an excessively large annulus can form spaces by falling behind Soil can no longer be dammed.
- d) Durch die Einstellbarkeit wird erreicht, daß eine kleinst mögliche Verdrängung des umliegen den Materials erreicht wird. Wodurch eine etwaige Beschädigung von parallellaufenden Leitungen oder Kanälen verhindert wird.d) The adjustability ensures that the smallest possible displacement of the surrounding area the material is reached. What a possible Damage to parallel lines or channels is prevented.
In Fig. 3 ist ein Anwendungsbeispiel dargestellt, das die Aufweitvorrichtung (E) im auseinanderge fahrenen Zustand in einem Kanal zeigt.In Fig. 3, an application example is shown, which shows the expanding device (E) in the extended state in a channel.
Die Aufweitvorrichtung wurde hierbei über einen vor handenen Schacht (W) eingebaut, wobei das Vorziehen über eine Umlenkrolle (D) im Schacht (U) durch eine funkgesteuerte hydraulische Seilwinde (B) erfolgt.The expanding device was installed over an existing shaft (W) , the pulling over a deflection roller (D) in the shaft (U) being carried out by a radio-controlled hydraulic cable winch (B) .
Das Nachführen der Spezialkurzrohre (G) erfolgt durch eine hydraulische Nachführvorrichtung (F), vom Schacht (W) aus gleichzeitig mit dem Vorziehen der Aufweitvorrichtung.The special short pipes (G) are fed through a hydraulic tracking device (F) from the shaft (W) at the same time as the expanding device is pulled forward.
Nach erreichen von Schacht (U) wird die Aufweit vorrichtung ausgebaut und die Spezialkurzrohre (G) bis in den Schacht (U) nachgeschoben.After reaching the shaft (U) , the expansion device is removed and the special short pipes (G ) are pushed into the shaft (U) .
Claims (11)
die Gehäuseteile (4) sind um die Längsachse der Auf weitvorrichtung herum nach außen beweglich bzw. schwenkbar angeordnet Fig. 2.3. Adjustable, hydraulic expansion device according to claim 1, characterized in that it consists of four conically curved housing parts Fig. 1 ( 4 ), which is exchangeable and movable by pivot connections Fig. 1 ( 13 ) and ( 14 ) with the base part ( 2 ) and the Ge housing parts ( 7 ) are connected;
the housing parts ( 4 ) are arranged around the longitudinal axis of the wide device on outward movable or pivotable Fig. 2nd
wodurch die Gehäuseteile Fig. 2A (7) und (4) von der Längsachse der Aufweitvorrichtung nach außen wegge drückt werden, was bewirkt, das die vorhandenen Kanalrohre gebrochen und mit dem Erdreich verdrängt werden.8. Adjustable, hydraulic expansion device according to claim 1, characterized in that by moving together the double-acting hydraulic cylinder ( 10 ), the pressure plate attached to the piston rod ( 11 ) pushes onto the contact surfaces of the slide rails ( 5 );
whereby the housing parts Fig. 2A ( 7 ) and ( 4 ) are pushed away from the longitudinal axis of the expander to the outside, which causes the existing sewer pipes to be broken and displaced with the ground.
