Description

MIT ARMATUREN AUSGERÜSTETER SCHACHT FÜR WASSER- BEZIEHUNGSWEISE DAMPFLEITUNGEN, INSBESONDERE FÜR WASSERUHRENFITTED SHAFT FOR WATER RELATIONSHIP STEAM PIPES, ESPECIALLY FOR WATER WATCHES
Die Erfindung betrifft einen mit Armaturen ausgerüsteten Schacht für Wasser- beziehungsweise Dampfleitungen, insbesondere für Wasseruhren.The invention relates to a shaft equipped with fittings for water or steam lines, in particular for water meters.
Die Schächte, in denen Wasseruhren angebracht werden, sind unterhalb der Frostgrenze in den Boden eingelassene, mit einem abnehmbaren Deckel versebene Objekte, die die Aufgabe haben, die am Anschlußort der von der medienfördernden Hauptleitung zum Verbraucher, im allgemeinen einem Familienhaus, abzweigenden Leitung die erforderlichen Armaturen, wie zum Beispiel Ventile, Knierohre, Wasserverbrauchsmesser ("Wasseruhr") usw. aufzunehmen und vor dem Einfrieren zu schützen.The shafts, in which water meters are attached, are objects embedded in the ground below the frost line, with a removable cover, which have the task of being the necessary ones at the connection point of the line branching from the media-promoting main line to the consumer, generally a family house Fitting fittings such as valves, knee tubes, water consumption meter ("water meter") etc. and to protect them from freezing.
Gegenwärtig sind der Einbau der Wasseruhr in den Schacht, ihr Anschluß, ihre Reparatur oder auch ihr Auswechseln Arbeitsgänge, die der Fachmann am Boden des Schachtes in Schmutz und Enge, unter unbequemen Bedingungen vornehmen muß. Zum Ablesen der Wasseruhr, das durchschnittlich etwa alle zwei Monate erfolgt, muß der Beamte in den Wasseruhrschacht einsteigen. Die bekannten Wasseruhrschächte bestehen meistens aus Beton und haben gegebenenfalls eine Bodenplatte. Sie sind mit einem abnehmbaren Deckel versehen.At the moment, the installation of the water meter in the shaft, its connection, its repair or also its replacement are work steps that the specialist on the bottom of the shaft has to carry out in dirty and confined spaces under uncomfortable conditions. To read the water meter, which takes place approximately every two months on average, the officer must enter the water meter shaft. The well-known water meter shafts mostly consist of concrete and may have a base plate. They are provided with a removable lid.
Aus der ungarischen Patentschrift Nr. ist ein mit Armaturen ausgerüsteter Schacht bekannt, bei dem das Schachtelement selbst aus Kunststoff besteht. Die Anordnung dieses Schachtelementes und seiner Armaturen entspricht im wesentlichen der bereits gegebenen Beschreibung. Die Patentschrift enthält auch einen Vorschlag, gemäß dem die Armaturen im Interesse einer leichteren Handhabung und einer besseren Ablesbarkeit der Wasseruhr mehr in der Nähe der Bodenoberfläche angebracht werden sollen. In diesem Falle muß jedoch für ein dickwandiges Schachtelement und für eine teure Wärmeisolierung gesorgt werden. Trotzdem kommt es vor, daß die Wasseruhr einfriert, wenn zum Beispiel 24 Stunden lang kein Wasser entnommen wird und die Außentemperatur -5 ºC beträgt.A shaft equipped with fittings is known from the Hungarian patent specification No. 1, in which the shaft element itself consists of plastic. The arrangement of this shaft element and its fittings essentially corresponds to the description already given. The patent also contains a proposal according to which the fittings in the interest of easier handling and better readability of the water meter should be placed more near the surface of the floor. In this case, however, a thick-walled shaft element and expensive thermal insulation must be provided. Nevertheless, the water meter will freeze if, for example, no water is drawn for 24 hours and the outside temperature is -5ºC.
Ziel der Erfindung ist es, die beschriebenen Mängel zu beseitigen und für Wasser- beziehungsweise Dampfleitungen einen mit Armaturen ausgrüsteten Schacht bereitzustellen, mit dem die Gefahr des Einfrierens unter verhältnismäßig geringem Aufwand völlig beseitigt werden kann und gleichzeitig die Armaturen für die Montage und Kontrolle von der Bodenoberfläche aus leicht zugänglich sind.The aim of the invention is to eliminate the shortcomings described and to provide a shaft equipped with fittings for water or steam lines, with which the risk of freezing can be completely eliminated with relatively little effort and at the same time the fittings for the assembly and control of the floor surface are easily accessible from.
Zur Lösung der gestellten Aufgabe wurde von einem Schacht ausgegangen, der in einem mit einem abnehmbaren Deckel versehenen, am Boden geschlossenen Schachtelement angeordnet die mit der medienfördernden Leitung in Verbindung stehenden Armaturen, zum Beispiel Zu- und Ableitungsrohre, Ventile, Verbrauchsmeßgeräte usw. enthält. Dieser Schacht wurde erfindungsgemäß dadurch weiterentwickelt, daß die zwischen der AuslaufÖffnung des hereinführenden Rohres und der Einlauföffnung des wegführenden Rohres eingebauten Armaturen in ihrer Grundstellung unterhalb der Frostgrenze angeordnet sind und mit einem bis in Bodenhöhe hinaufreichend Henkel in Verbindung stehen, daß ferner das hereinführende Rohr und das wegführende Rohr wenigstens zum Teil als flexibler Schlauch und/oder als elastisches Rohr ausgebildet sind, deren eines Ende durch das Schachtelement führt und deren anderes Ende mittels des Henkels bis in Bodenhöhe anhebbar angeordneten Armaturen in Verbindung steht.To solve the problem, a shaft was assumed which, in a shaft element which is provided with a removable cover and is closed at the bottom, contains the fittings connected to the media-conveying line, for example supply and discharge pipes, valves, consumption meters, etc. This shaft was further developed according to the invention in that the fittings installed between the outlet opening of the pipe leading in and the inlet opening of the pipe leading away are arranged in their basic position below the frost limit and are connected to a handle reaching up to the level of the ground, and further that the pipe entering and the leading pipe at least in part as flexible hose and / or are designed as an elastic tube, one end of which leads through the shaft element and the other end of which is connected by means of the handles which can be raised to floor level.
Es ist zweckmäßig, wenn hereinführendes und wegführendes Rohr aus bis zur Formbeständigkeit wärmebehandeltem Polyäthylen in Form einer Rohrspirale ausgebildet sind. Vorteilhaft ist es auch, wenn die beiden Rohrspiralen axial angeordnet und ineinandergepaßt sind (ähnlich wie die Gänge einer Zweigang-Gewindeschnecke), denn in diesem Falle bleibt in Innenraum der Pohrspirale genügend Platz für die Armaturen.It is expedient if the incoming and outgoing pipe are formed from polyethylene heat-treated to the dimensional stability in the form of a pipe spiral. It is also advantageous if the two pipe spirals are arranged axially and fit into one another (similar to the threads of a two-speed screw), because in this case there is enough space in the interior of the pipe spiral for the fittings.
Das Schachtelement ist ein zweckmäßig aus Polyäthylen vorgefertigtes Element, das die Form eines zylindrischen Behälters hat. Das Schachtelenent kann im Interesse einer besseren Verankerung im Boden mit einem radialen Verankerungsrand beziehungsweise -ring versehen sein.The shaft element is a suitably prefabricated element made of polyethylene, which has the shape of a cylindrical container. In the interest of better anchoring in the ground, the box element can be provided with a radial anchoring edge or ring.
Die Erfindung wird an Hand der Zeichnungen näher erläutert.The invention is explained in more detail with reference to the drawings.
Fig. 1 zeigt einen senkrechten Schnitt durch den erfindungsgemäßen, mit Armaturen ausgerüsteten Schacht, währendFig. 1 shows a vertical section through the shaft equipped with fittings, while
Fig. 2 den Schnitt entlang der in Fig. 1 mit II-II bezeichneten Linie darstellt.Fig. 2 shows the section along the line designated by II-II in Fig. 1.
Wie aus Fig. 1 ersichtlich, ist das Schachtelement 1 des erfindungsgenäßen Wasseruhrschachtes so in den Boden eingesenkt, daß sein oberer Rand über das Erdbodenniveau heraussteht. Im vorliegenden Fall ist das Schachtelement 1 ein aus Polyäthylen bestehender zylindrischer Behälter mit 5 mm Wandstärke, dessen Mantel 2 wasserdicht mit einer Bodenplatte 3 verschweißt ist. Der obere Teil des Mantels 2 wird durch einen abnehmbaren, gebördelten Deckel 4 verschlossen, der an beiden Seiten mit je einem Griff 5 und an der Innenfläche mit einer ringförmigen Versteifung 6 versehen ist. Der Deckel 4 ist im vorliegenden Falle ebenfalls aus Polyäthylen gefertigt, und zwar mit 7 mm Wandstärke. Im Zuge der vorgenommenen Versuche wurden der Durchmesser des Schachtelementes 1 mit 500 mm, die Höhe mit 1300 mm gewählt.As can be seen from FIG. 1, the shaft element 1 of the water meter shaft according to the invention is sunk into the ground in such a way that its upper edge protrudes above the ground level. In the present case, the shaft element is 1 a cylindrical container made of polyethylene with a wall thickness of 5 mm, the jacket 2 of which is welded watertight to a base plate 3. The upper part of the jacket 2 is closed by a removable, flanged cover 4, which is provided on both sides with a handle 5 and on the inner surface with an annular stiffener 6. The cover 4 is also made of polyethylene in the present case, with a wall thickness of 7 mm. In the course of the tests carried out, the diameter of the shaft element 1 was chosen to be 500 mm and the height to be 1300 mm.
In der Ausführungsform gemäß Fig. 1 setzt sich die Bodenplatte 3 in einem ringförmigen Rand 7 fort, der zum Beispiel in sandigem Boden die Verankerung des Schachtelementes 1 verbessert. Gegebenenfalls, zum Beispiel bei hohem Grundwasserstand, ist es zweckmäßig, das Schachtelement 1 mit einem das Aufschwimmen verhindernden Ring 8 zu versehen.In the embodiment according to FIG. 1, the base plate 3 continues in an annular edge 7, which improves the anchoring of the shaft element 1 in sandy soil, for example. If necessary, for example when the groundwater level is high, it is advisable to provide the shaft element 1 with a ring 8 which prevents it from floating.
In Fig. 1 ist die Frostgrenze mit einer dünnen Linie angedeutet und mit dem Bezugszeichen 9 versehen. Die Frostgrenze liegt in etwa 80 cm Tiefe. Unterhalb der Frostgrenze 9 sind in ihrer Grundstellung die folgenden Armaturen angeordnet: das mit der nicht besonders gekennzeichneten medien fördernden Leitung verbundene hereinführende Rohr 10, das zu dem ebenfalls nicht eingezeichneten Verbraucher führende wegführende Rohr 11, ferner zwischen diesen auf jeder Seite ein Knierohr 12 beziehungsweise 13 und unter Zwischenschalt eines Ventils 14 ein in bekannter Weise aufgebauter Verbrau messer (im vorliegenden Fall eine Wasseruhr). Erfindungsgemäß sind das hereinführende Rohr 10 und das wegführende Rohr 11 wenigstens zum Teil als flexibler Schlauch und/oder als elastisches, druckfestes Rohr ausgebildet. In dem dargestellten Fall sind hereinführendes Rohr 10 und wegführendes Rohr 11 - abgesehen von den Endabschnitten - als koaxial ineinandergepaßte Rohrspiralen ausgeführt. Die Rohre haben einen Durchmesser von 25 mm und eine Wandstärke von 2,5 mm. Im vorliegenden Fall bestehen hereinführendes Rohr 10 und wegführendes Rohr 11 aus Hartpolyäthylen. Damit die Rohre ihre gewünschte spirale Form beibehalten, werden sie während der Herstellung einer formbewahrenden Wärmebehandlung unterzogen, in deren Verlauf auf eine längere Wärmebehandlung bei 120-150 ºC plötzliches Abkühlen in Wasser folgt.In Fig. 1 the frost line is indicated with a thin line and provided with the reference number 9. The frost limit is about 80 cm deep. Below the frost limit 9, the following fittings are arranged in their basic position: the incoming pipe 10 connected to the media-conveying line, which is not particularly marked, the outgoing pipe 11 leading to the consumer (also not shown), and between them a knee pipe 12 or 13 on each side and with the interposition of a valve 14 a consumption knife constructed in a known manner (in the present case a water meter). According to the invention, the pipe 10 leading in and the pipe 11 leading away are at least partially designed as a flexible hose and / or as an elastic, pressure-resistant pipe. In the case shown, the incoming pipe 10 and away pipe 11 - apart from the end sections - are designed as coaxially fitted pipe spirals. The tubes have a diameter of 25 mm and a wall thickness of 2.5 mm. In the present case, incoming pipe 10 and away pipe 11 are made of hard polyethylene. In order for the tubes to maintain their desired spiral shape, they are subjected to a shape-retaining heat treatment during manufacture, which is followed by a prolonged heat treatment at 120-150ºC in water.
Das untere Ende des hereinführenden Rohres 10 und des wegführenden Rohres 11 sind durch im Mantel des Schachtelementes 1 angebrachte Bohrungen 18 beziehungsweise 19 nach außen geführt und durch wasserdichte Schweißbindung befestigt (s. Fig. 2). Das obere Ende des hereinführenden Rohres 10 beziehungsweise des wegführenden Rohres 11 sind über das Rohrknie 12, das Ventil 14 und das Rohrknie 13 auf die in Fig. 1 gezeigte Weise von beiden Seiten an den Verbrauchsmesser 15 angeschlossen. Das in das hereinführende Rohr 10 eingebaute Ventil 14 kann ein beliebiges bekanntes Schließventil sein, das in das wegführende Rohr 11 eingebaute Ventil ist jedoch zweckmäßig ein Strömung nur in einer Richtung zulassendes Rückschlagventil. Das Rohrknie 12 ist mit de Auslauföffnung des hereinführenden Rohres 10 beziehungsweise mit der Einlauföffnung des wegführenden Rohres 11 durch eine Schweißverbindung, mit den Ventilen 14 jedoch durch eine Schraubverbindung verbunden. Die Rohrkniee 13 sind mit den Ventilen 14 beziehungsweise mit den Anschlußstutzen des Verbrauchsmessers 15 in üblicher Weise durch Schraubverbindungen verbunden. Die Rohrkniee 12 und 13 sind im vorliegenden Fall ebenfalls aus Polyäthylen gefertigt.The lower end of the pipe 10 leading in and the pipe 11 leading away are led to the outside through bores 18 and 19 made in the casing of the shaft element 1 and fastened by means of a waterproof welded bond (see FIG. 2). The upper end of the pipe 10 leading in and the pipe 11 leading away are connected to the consumption meter 15 from both sides via the pipe elbow 12, the valve 14 and the pipe elbow 13 in the manner shown in FIG. 1. The valve 14 installed in the incoming pipe 10 can be any known closing valve, but the valve installed in the outgoing pipe 11 is expediently a one-way flow check valve. The pipe bend 12 is with the outlet opening of the pipe 10 entering with the inlet opening of the pipe 11 leading away by a welded connection, but connected to the valves 14 by a screwed connection. The elbows 13 are connected to the valves 14 or to the connecting piece of the consumption meter 15 in the usual way by screw connections. The pipe elbows 12 and 13 are also made of polyethylene in the present case.
Wie in Fig. 1 angedeutet, können die Armaturen aus ihrer mittels einer durchgehenden Linie bezeichneten Grundstellung bis in Bodenhöhe angehoben werden, zum Beispiel mittels das an den Rohrknieen 12 befestigten Henkels 16. Das Anheben der Armaturen kann zum Beispiel beim Ablesen des Verbrauchsmessers 15 oder beim Einbau von Armaturen, ihrer Kontrolle oder Reparatur erforderlich sein. Dabei folgen die oberen Enden des hereinführenden Rohres 10 und das wegführenden Rohres 11 der Bewegung der Armaturen, d.h. im vorliegenden Fall tritt eine elastische Deformation der Rohrspiralen ein, sie werden in senkrechter Richtung auseinandergezogen. Nach Beendigung der Arbeiten werden die Armaturen mittels des Henkels IG in ihre Grundstellung zurückgesenkt. Währenddessen gewinnen das hereinführende Rohr 10 und das wegführende Rohr 11 ihre ursprüngliche Gestalt zurück. Schließlich wird das Schachtelement 1 mit dem Deckel 4 verschlossen.As indicated in Fig. 1, the fittings can be raised from their basic position indicated by a solid line to floor level, for example by means of the handle 16 attached to the pipe elbows 12. The fittings can be lifted, for example, when reading the consumption meter 15 or when Installation of fittings, their inspection or repair may be necessary. The upper ends of the incoming pipe 10 and the away pipe 11 follow the movement of the fittings, i.e. in the present case there is an elastic deformation of the tube spirals, they are pulled apart in the vertical direction. After completing the work, the fittings are lowered back into their basic position using the IG handle. In the meantime, the incoming pipe 10 and the outgoing pipe 11 regain their original shape. Finally, the shaft element 1 is closed with the cover 4.
Der erfindungsgemäße, vorgefertigte Gehacht ist sowohl Grundwasser gegenüber wie auch Niederschlägswasser und Oberflächcnwasser gegenüber als dicht schließend zu betrachten. Während der Montagearboiten gelangt jedoch unvermeidlich Wasser in den Innenraum des Schachtelementes 1. Zu dessen Entfernung wurde bei den Versuchen eine bekannte Handwasserpumpe verwendet, die auf der Zeichnung nicht dargestellt ist.The prefabricated saliva according to the invention is to be regarded as tightly closing both against groundwater and against precipitation water and surface water. However, during the assembly work inevitably arrives Water into the interior of the shaft element 1. To remove it, a known hand-water pump was used in the tests, which is not shown in the drawing.
Das Schachtelement 1 kann natürlich auch in beliebiger anderer Ausführung angefertigt werden, es kann zum Seispiel den Querschnitt eines Vielecks oder einen ovalen Querschnitt haben. Als Material kommen neben Polyäthylen auch andere bekannte Kunststoffe, zum Beispiel glasfaserverstärkte Polyester, ferner Beton in Frage.The shaft element 1 can of course also be made in any other design, for example it can have the cross section of a polygon or an oval cross section. In addition to polyethylene, other known plastics, for example glass fiber-reinforced polyester, and also concrete can be used as the material.
Das hereinführende Rohr 10 und das wegführende Rohr 11 sind im Falle der Ausführungsbeispiele aus elastischem, wärmebehandeltem Hartpolyäthylen gefertigt, das infolge seiner Elastizität auch bei Deformationen seine zylindrische Form behält. Für diesen Zweck können jedoch auch andere geeignete elastische und druckfeste Rohre verwendet werden. Außer den Rohrspiralen kommen auch noch andere Formen der Roh ranordnung in Frage; jede Rohranordnung ist geeignet, die es ermöglicht, die Armaturen aus ihrer Grundstellung bis auf Bodenhöhe anzuheben. Das hereinführende Rohr 10 und das wegführende Rohr 11 können aber auch aus flexiblen Kunststoff- oder Gummischläuche bestehen. In diesen Fällen ist es zweckmäßig, während des Hebens beziehungsweise Absenkens für eine seitliche Führung zu sorgen. Ferner können Ausführungsformer, zweckmäßig sein, bei denen das hereinführende Rohr 10 und das wegführende Rohr 11 aus beliebigen Kombinationen von elastischen, flexibler, und/oder starren Rohrabschnitten besteht.The incoming pipe 10 and the outgoing pipe 11 are made in the case of the exemplary embodiments from elastic, heat-treated hard polyethylene, which retains its cylindrical shape due to its elasticity even when deformed. However, other suitable elastic and pressure-resistant pipes can also be used for this purpose. In addition to the pipe spirals, other forms of pipe arrangement are also possible; any pipe arrangement is suitable which enables the fittings to be raised from their basic position to floor level. The incoming pipe 10 and the outgoing pipe 11 can also consist of flexible plastic or rubber hoses. In these cases, it is advisable to provide lateral guidance while lifting or lowering. Furthermore, embodiment forms can be expedient, in which the incoming pipe 10 and the away pipe 11 consist of any combination of elastic, flexible, and / or rigid pipe sections.
Vorstellbar ist auch eine Ausführungsform, bei der unter den Armaturen eine Montageplatte angebracht ist, die mittels des Henkels im Innenrαurn des Schachtes auf- und abwärts bewegt werden kann, und die Armaturen sind auf dieser Montageplatte befestigt.An embodiment is also conceivable in which a mounting plate is attached under the fittings, which can be moved up and down in the interior of the shaft by means of the handle, and the fittings are attached to this mounting plate.
Der Henkel 15 muß nicht unbedingt die in Fig. 1 gezeigte bogenförmige Form haben. Statt des Henkels kann auch eine mittige Stange, eine Kette oder ein Seil verwendet werden.The handle 15 need not necessarily have the arcuate shape shown in FIG. 1. Instead of the handle, a central rod, a chain or a rope can also be used.
Erwähnt Werden muß ferner, daß die erfindungsgemäße Lösung nicht nur für Wasseruh rschächte, sondern darüber hinaus noch an zahlreichen Orten eingesetzt werden kann, zum Beispiel für Wasserhähne im Garten oder für die Wasseranschlüsse von Gieß- und Beregnungsvorrichtungen als mit Armaturen versehener Schacht. Die erfindungsgemäße Lösung kann ferner mit Vorteil auch für die Warmwasser- beziehungsweise Gasanschlüsse der Eisenbahn verwendet werden. Diese Anschlüsse sind ebenfalls in Schächten angebracht, an sie werden zum Beispiel die zur Reinigung von Lokomotiven verwendeten unterschiedlichen Werkzeuge angeschlossen.Must also be mentioned that the solution according to the invention rschächte not only for Wasseruh, but can also be used in numerous places, for example for taps in the garden or for the water connections of watering and irrigation devices as a valve provided with fittings. The solution according to the invention can also advantageously be used for the hot water or gas connections of the railway. These connections are also installed in shafts, to which, for example, the various tools used for cleaning locomotives are connected.
Der Hauptvorteil des erfindungsgemäßen, mit Armaturen ausgerüsteten Schachtes besteht darin, daß er die Gefahr des Einfrierens völlig beseitigt, in seinem Aufbau verhältnismäßig einfach und billig ist und ermöglicht, daß zur Montage und Kontrolle die Armaturen auf Bodenhöhe angehoben, d.h. gut zugänglich gemacht werden können. Ein zusätzlicher Vorteil besteht darin, daß der Schacht im Freien oder in einen Gebäude schnell zusammengesetzt und angebracht werden kann und auch zur Erneuerung bereits vorhandener Schäohte verwondbar ist. The main advantage of the shaft equipped with fittings according to the invention is that it completely eliminates the risk of freezing, its construction is relatively simple and cheap and enables the fittings to be raised to floor level for assembly and control, i.e. can be made easily accessible. An additional advantage is that the shaft can be quickly assembled and attached outdoors or in a building and can also be used to renew existing foams.
