Description

Die Erfindung betritt ein Verfahren zur Herstellung einer Straße, bei dem eine Absperrarmatur Unterflur, am Grund eines Rohrgrabens vorgesehen wird, eine verlängerbare Schlüsselstange von der Absperrarmatur nach oben rangend angeordnet wird, der Rohrgraben ausgefüllt wird, eine über den ausgefüllten Rohrgraben hinweggehende Straßendecke gebaut wird, eine Verlängerung der Schlüsselstange zur Gebrauchslänge durchgeführt wird, nach dem Bau der Straßendecke eine Aufgrabung erfolgt und die Aufgrabung bei zur Gebrauchslänge verlängerter Schlüsselstange wieder ausgefüllt wird.The invention relates to a method for producing a road, in which a shut-off valve is provided under the floor, at the bottom of a pipe trench, an extendable key bar is arranged so that it extends upward from the shut-off valve, the pipe trench is filled, a road surface is built over the filled pipe trench, an extension of the key bar to the working length is carried out, after the construction of the road surface a digging is carried out and the digging is completed again with the key bar extended to the working length.

Die Erfindung betrifft auch eine Erdeinbaugarnitur für eine Unterflur angeordnete Absperrarmatur, mit einer Schlüsselstange, bei der ein, eine untere Kuppelmuffe tragendes Teleskoprohr eine, eine obere Steckpassung tragende Teleskopstange verschiebbar aufnimmt und eine klemmende Festlegung der Teleskopstange gegenüber dem Teleskoprohr derart vorgesehen ist, daß die Te- leskopstanfe am Teleskoprohr getragen ist, insbesondere zur Durchführung des vorhergenannten VerfahrensThe invention also relates to an in-ground installation for a shut-off valve arranged under the floor, with a key rod in which a telescopic tube carrying a lower coupling sleeve slidably receives a telescopic rod carrying an upper plug fit and a clamping fixation of the telescopic rod relative to the telescopic tube is provided in such a way that the Te - Leskopstan f e is worn on the telescopic tube, in particular to carry out the aforementioned method

Mit einer bekannten (DE-PS 16 03 926) Schlüsselstange der hier zur Rede stehenden Art wird eine Straße in der Praxis folgendermaßen hergestellt: Die Schlüsselstange wird bereits vor dem Bau der Straßendecke soweit verlängert, daß sie aus dem ausgefüllten Rohrgraben herausragt, wobei die genaue Einstellung der Gebrauchslänge vor dem Bau der Straßendecke erfolgt Da die Schlüsselstange mit ihrem oberen Endstück genau dort nach oben ragt, wo die Straßendecke gebaut wird, ist sie während des Straßenbaues hinderlich und kann während des Straßenbaues leicht beschädigt werden- Die Baufahrzeuge, die der Schlüsselstange ausweichen . sollten, stoßen häufig gegen die Schlüsselstange, wodurch diese verbogen und unbrauchbar wird. Zum Einsetzen einer neuen geraden Schlüsselstange muß der Rohrgraben bis hinab zur Absperrarmatur aufgegraben werden. Es ist daher auch üblich, vor dem Ausfüllen des Rohrgrabens und dem Bau der Straßendecke keine Schlüsselstange vorzusehen und nach dem Bau der Straßendecke durch den ganzen Rohrgraben hindurch zum Unterflurabsperrorgan aufzugraben, die Schlüsselstange auf Gebrauchslänge eingestellt aufzustecken und die Aufgrabung wieder auszufüllen.With a known (DE-PS 16 03 926) key bar of the type in question, a road is made in practice as follows: the key bar is extended before the road surface is built so that it protrudes from the filled pipe trench, the exact Adjustment of the working length is carried out before the construction of the road surface. Since the key rod protrudes with its upper end exactly where the road surface is being built, it is a hindrance during road construction and can easily be damaged during road construction - the construction vehicles that avoid the key pole . should frequently hit the key bar, making it bent and unusable. To insert a new straight key rod, the pipe trench must be dug down to the shut-off valve. It is therefore also customary not to provide a key bar before filling the pipe trench and building the road surface, and after building the road surface to dig through the entire pipe trench to the underfloor shut-off device, to attach the key bar to the length of use and to complete the excavation again.

Eine Aufgabe der Erfindung ist es somit, ein Verfahren der eingangs genannten Art zu schaffen, bei dem nicht nur Beschädigungen einer aus dem Rohrgraben herausragenden Schlüsselstange während des Baues der Straßendecke vermieden sind, sondern auch ein nachträgliches Wiederaufgraben bis hinab zur Absperrarmatur vermieden ist, indem die Verlängerbarkeit der Schlüsselstange ausgenützt wird. Das erfindungsgemäße Verfahren ist, diese Aufgabe lösend, dadurch gekennzeichnet, daß die Schlüsselstange vor dem Bau der Straßendecke auf eine Anorndung des oberen Endes innerhalb des Rohrgrabens kurz unter der zu bauenden Straßendecke verkürzt eingestellt wird, die nach dem Bau der Straßendecke erfolgende Aufgrabung nur bis zum oberen Ende der Schlüsselstange erfolgt und die Verlängerung zur Gebrauchslänge unter Herausbewegen des oberen Schlüsselstangen-Endes aus dem nahezu vollständig ausgefüllten Rohrgraben erfolgtAn object of the invention is therefore to provide a method of the type mentioned, in which not only damage to a key stick protruding from the pipe trench is avoided during the construction of the road surface, but also subsequent digging down to the shut-off valve is avoided by the Extensibility of the key bar is exploited. The method according to the invention is this Solving the problem, characterized in that the key bar is shortened before the construction of the road surface to a location of the upper end within the pipe trench just below the road surface to be built, the excavation taking place after the construction of the road surface takes place only up to the upper end of the key rail and the extension to the working length takes place by moving the upper end of the key bar out of the almost completely filled pipe trench

Da bei dem erfindungsgemäßen Verfahren die SchlUsselstange während des Baues der Straßendecke nicht aus dem Rohrgraben herausragt, kann sie nicht beschädigt werden. Das nachträgliche Aufgraben nur bis zum oberen Ende der Schlüsselstange verursacht relativ wenig Aufwand. Das erfindungsgemäße Verfahren führt zu einer beachtlichen Verkürzung der für die Herstellung der Straße erforderlichen Zeit, da die Baumaschinen ungehindert fahren können und grabentiefe Aufgrabungen entfallen. Obzwar es denkbar ist, die verkürzte Schlüsselstange durch Aufstecken eines Stangenstückes zu verlängern, wird in der Regel eine Schlüsselstange verwendet, bei der eine Teleskopstange in einem Teleskoprohr steckt und Teleskopstange und Teleskoprohr gegeneinander in Längsrichtung verstellbar sind.Since in the method according to the invention the key bar does not protrude from the pipe trench during the construction of the road surface, it cannot be damaged. The subsequent digging up to the upper end of the key bar causes relatively little effort. The method according to the invention leads to a considerable reduction in the time required for the production of the road, since the construction machines can travel unhindered and trench-deep excavations are dispensed with. Although it is conceivable to extend the shortened key bar by plugging on a piece of bar, a key bar is generally used in which a telescopic bar is inserted in a telescopic tube and the telescopic rod and telescopic tube are adjustable in the longitudinal direction relative to one another.

Besonders zweckmäßig und vorteilhaft ist es, wenn eine Schlüsselstange, die in der verlängerten Gebrauchslänge gegen Zug in' Längsrichtung gesichert festgelegt ist, verwendet wird. Es kann nun ein auf das obere Schlüsselstangen-Ende aufgesetzter dem Drehen der Schlüsselstange dienender Schlüssel auch bei starker Verklemmung abgezogen werden, ohne daß sich der obere Teil der Schlüsselstange von deren unterem. Teil löst.Particularly useful and advantageous it is if a key rod, which is fixed secured in the prolonged use to train length in 'the longitudinal direction, is used. It can now be placed on the upper end of the key bar Turning the key bar serving key can be removed even with strong jamming, without the upper part of the key bar from the lower. Part solves.

Für das erfindungsgemäße Verfahren läßt sich an sich auch die bekannte (DE-PS 16 03 926) Schlüsselstange der eingangs genannten Art verwenden. Bei dieser ist das umschließende Stück ein kompakter, starrer Ring, der in radialer Richtung von zwei Schrauben durchdrungen ist, die gegen das Innenrohr verspannt sind. Der Ring liegt nur lose auf dem oberen Rohrstangen-Ende auf Nachteiligerweise sind hier Innenstange und Rohrstange nicht zugfest verbunden. Dabei ist zwar die Klemm-Festlegung durch Drehen der Schraubteile an sich von Vorteil, aber wegen der radial angeordneten Schrauben praktisch nur durchführbar, wenn das umschließende Stück samt Innenstange von der Rohrstange nach oben weggezogen ist.The known (DE-PS 16 03 926) key bar of the type mentioned at the outset can also be used for the method according to the invention. In this case, the enclosing piece is a compact, rigid ring which is penetrated in the radial direction by two screws which are braced against the inner tube. The ring lies only loosely on the upper end of the tubular rod. Unfortunately, the inner rod and the tubular rod are not connected in a tensile manner. In this case, the clamping fixation by turning the screw parts per se is advantageous, but because of the radially arranged screws, it can practically only be carried out if the surrounding piece, including the inner rod, has been pulled upward away from the tubular rod.

Eine weitere Aufgabe der Erfindung ist es daher, eine Erdeinbaugarnitur der eingangs genannten Art zu schaffen, bei der, insbesondere zwecks verbesserter Durchführung des erfindungsgemäßen Verfahrens, die Längenveränderung in vereinfachter Weise durchführbar ist. Die erfindungsgemäße Einbaugarnitur ist, diese Aufgabe lösend, dadurch gekennzeichnet, daß ein einerseits an der Teleskopstange abgestützten Federelement andererseits mit einem Klemmglied gegen die Innenseite des Teleskoprohres gleitbar abgestützt ist.Another object of the invention is therefore to provide an underground installation set of the type mentioned, in which, in particular for the purpose of improving the method according to the invention, the length change can be carried out in a simplified manner. The installation set according to the invention solves this problem, characterized in that a spring element supported on the one hand on the telescopic rod is on the other hand slidably supported with a clamping member against the inside of the telescopic tube.

Bei der erfindungsgemäßen Erdeinbaugarnitur kann die Schlüsselstange ausgezogen werden, ohne von alleine wieder zurückzufallen, da eine selbstätige Klemmung zwischen Teleskoprohr und Teleskopstange vorgesehen ist. Diese Klemmung oder Reibung ist aber nur so groß, daß sie durch kräftigen Zug oder Druck überwunden werden kann. Stange und Rohr sind unter Schwergängigkeit ineinander schiebbar und die Teleskopstange bleibt in jeder Stellung von alleine stehen Hierzu und für eine Längenveränderung ist kein Werkzeug nötig. Diese Eigenschaften der erfindungsgemäßen Schlüsselstange sind schon bei unverfülltem Rohrgraben von Nutzen, weil sich die Länge der Schlüsselstange ohne unveränderbare Festleg-ung einstellen läßt.In the underground installation set according to the invention, the key rod can be pulled out without falling back on its own, since an automatic clamping between the telescopic tube and the telescopic rod is provided. This clamping or friction is only so great that it can be overcome by strong pull or pressure. Rod and tube can be slid into each other with difficulty and the telescopic rod remains in any position by itself. No tools are required for this and to change the length. These properties of the key rod according to the invention are useful even in the case of unfilled pipe trenches, because the length of the key rod can be adjusted without being fixed.

Besonders zweckmäßig und vorteilhaft ist es, wenn die Schlüsselstange in einem schützenden Teleskop-Hülsrohr angeordnet ist, dessen oberes Rohr oben einen Deckel mit Stützplatte trägt, der mit der Teleskopstange der Schlüsselstange in Achsrichtung unverschiebbar verbunden ist. Hierbei ist nicht nur die Schlüsselstange durch das Teleskop-Hülsrohr in längenver- änderbarer Weise gegen das Erdreich geschützt. Vielmehr ist die Teleskopstange der Schlüsselstange auch mittels der Stützplatte gegen das Erdreich abgestützt, so daß die Schlüsselstange nicht ungewollt durch Druck von oben oder durch ein Nachlassen der Klemmreibung verkürzt werden kann.It is particularly expedient and advantageous if the key rod is arranged in a protective telescopic sleeve tube, the upper tube of which carries a cover with a support plate at the top, which is connected to the telescopic rod of the key rod so that it cannot move in the axial direction. It is not only the key bar that is protected against the ground by the telescopic sleeve tube in a length-adjustable manner. Rather, the telescopic rod of the key rod is also supported against the ground by means of the support plate, so that the key rod cannot be inadvertently shortened by pressure from above or by a reduction in the clamping friction.

Die Kombination der Stützplatte mit dem gleitbar wirkenden Federelement bewirkt einerseits, daß die Schlüsselstange sich aufgrund von Erderschütterungen nicht ohne weiteres unter Überwindung der Federelement-Klemmung zusammenschieben kann, da sie von der Stützplatte gehalten ist, und andererseits, daß die SchlUsselstange bei starkem Druck von oben nachgeben kann, ohne daß das Hülsrohr oder auch die Klemmeinrichtung beschädigt wird, da das erfindungsgemäß verwendete Federelement eine Verschiebung zuläßt. Die Klemmung kann bei verstärktem Druck durch-rutschen, ohne daß Beschädigungen entstehen.The combination of the support plate with the slidably acting spring element causes on the one hand that the key bar itself due to earth vibrations can not be easily pushed together by overcoming the spring element clamping, since it is held by the support plate, and on the other hand, that the key rod can yield under high pressure from above, without the sleeve tube or the clamping device being damaged, since that Spring element used according to the invention allows a displacement. The clamp can slip under increased pressure without causing damage.

Zur Klemmung läßt sich z.B. eine von einer Wendelfeder beaufschlagte Kugel vorsehen, die aus einer Führungsbohrung der Teleskopstange herausragt und gegen das Teleskoprohr drückt. Besonders zweckmäßig und vorteilhaft ist es jedoch, wenn das Federelement und das Klemmglied von einer Blattfeder gebildet sind, die in einer Ausnehmung der Teleskopstange angeordnet ist. Diese Ausgestaltung ist kräftig, einfach und wenig störanfällig.For clamping, e.g. provide a ball loaded by a helical spring, which protrudes from a guide hole in the telescopic rod and presses against the telescopic tube. However, it is particularly expedient and advantageous if the spring element and the clamping member are formed by a leaf spring which is arranged in a recess in the telescopic rod. This configuration is strong, simple and less prone to failure.

Besonders zweckmäßig und vorteilhaft ist es weiterhin, wenn nahe dem oberen Ende des Teleskoprohres an dessen Innenseite ein Widerlager für das Klemmglied vorgesehen ist. Hierdurch ist in sehr einfacher Weise ein Herausziehen der Teleskopstange aus dem Teleskoprohn verhindert.It is also particularly expedient and advantageous if an abutment for the clamping member is provided on the inside near the upper end of the telescopic tube. This prevents the telescopic rod from being pulled out of the telescopic tube in a very simple manner.

Gemäß Fig. 1 ist im Boden 1 ein Rohrgraben 2 vorgesehen, an dessen Grund sich Rohrleitungen und Armaturen, nämlich eine Unterflur-Absperrarmatur 3 befinden. Auf die als nach oben ragender Vierkant ausgebildete Betätigungsspindel der Absperrarmatur ist eine Kuppelmuffe gesetzt und gesplintet, in die eine SchlUsselstange 4 ragt, deren am unteren Ende befindlicher Schlüssel mit der Kuppelmuffe versplintet ist, wie Fig. 2 zeigt. Die Schlüsselstange 4 endet oben kurz vor dem oberen Ende des Rohrgrabens 2 und ist von einem schützenden Teleskop-Hülsrohr umgeben, dessen unteres Rohr 5 auf der Armatur aufsteht und dessen oberes Rohr 6 außen aufgeschoben ist. Der Rohrgraben 2 ist mit Erdreich aufgefüllt.1, a pipe trench 2 is provided in the bottom 1, at the bottom of which there are pipes and fittings, namely an underfloor shut-off valve 3. On the actuating spindle of the shut-off valve, which is designed as an upwardly projecting square, a coupling sleeve is placed and splinted, into which a key rod 4 protrudes, the key of which is located at the lower end and is split together with the coupling sleeve, as shown in FIG. 2. The key rod 4 ends at the top shortly before the upper end of the pipe trench 2 and is surrounded by a protective telescopic sleeve pipe, the lower pipe 5 of which stands on the fitting and the upper pipe 6 is pushed on the outside. The pipe trench 2 is filled with soil.

Oberhalb des Rohrgrabens 2 verläuft eine aus mehreren waagerechten Schichten zusammengesetzte Straßendecke 7, in der in Verlängerung der Schlüsselstange 4 eine Aufgrabung 8 vorgesehen ist, die sich auch noch auf den obersten Bereich des den Rohrgraben 2 ausfüllenden Erdreiches erstreckt. Nach Herstellung der Aufgrabung 8 wird das obere Rohr 5 des Teleskop-Hülsrohres hochgezogen und wird die Schlüsselstange in die gestrichelte Stellung 4' verlängert. Sodann wird die Straßendecke im Bereich der Aufgrabung 8 wieder hergestellt. Das obere Rohr 6 des Hülsrohres trägt oben einen Deckel 9, der auf der Teleskopstange der Schlüsselstange 4 drehbar, aber nicht verschiebbar ist, wie Fig. 2 erkennen läßt. Der Deckel 9 ist mit einer Stützplatte 10 versehen, die auf dem Erdreich bzw. Straßendecke aufliegt.Above the pipe trench 2 there is a road surface 7 composed of several horizontal layers, in which an extension 8 is provided as an extension of the key rod 4, which also extends to the uppermost region of the soil filling the pipe trench 2. After the excavation 8 has been produced, the upper tube 5 of the telescopic sleeve tube pulled up and the key rod is extended into the dashed position 4 '. The road surface in the area of the excavation 8 is then restored. The upper tube 6 of the sleeve tube carries a cover 9 at the top, which can be rotated on the telescopic rod of the key rod 4, but cannot be displaced, as can be seen in FIG. 2. The cover 9 is provided with a support plate 10 which rests on the ground or road surface.

Die Schlüsselstange 4 besteht aus einem unteren Teleskoprohr 11, das mit der Kuppelmuffe versplintet ist und einer Teleskopstange 12, die in dem Teleskoprohr auf und abverschiebbar geführt ist. Teleskoprohr und Teleskopstange sind im Querschnitt rechteckig oder durch andere eckige Gestaltung gegen ein gegenseitiges Verdrehen gesichert. Die Teleskopstange 12 besitzt nahe dem unteren Ende-eine seitliche Ausnehmung 13, in der als Federelement 14 eine zweifach gebogene Blattfeder vorgesehen ist, deren eines Ende an der Teleskopstange befestigt ist. Das Teleskoprohr 11 besitzt nahe dem oberen Ende einen Durchbruch, dessen oberes Ende ein Widerlager 15 bildet. Kurz bevor die Teleskopstange 12 vollständig aus dem Teleskoprohr gezogen ist, kann das freie Endstück der Blattfeder 14 in den Durchbruch eitrenten und sich an das Widerlager 15 anlegen. Das freie Endstück der Blattfeder 14 wirkt als Klemmglied 16, sobald die Teleskopstange etwas weiter als Fig. 3 gezeigt in das Teleskoprohr geschoben wird.The key rod 4 consists of a lower telescopic tube 11, which is spinned with the coupling sleeve, and a telescopic rod 12, which is guided in the telescopic tube so that it can be moved up and down. The cross-section of the telescopic tube and telescopic rod is rectangular or secured against mutual twisting by another angular design. Near the lower end, the telescopic rod 12 has a lateral recess 13 in which a double-curved leaf spring is provided as the spring element 14, one end of which is attached to the telescopic rod. The telescopic tube 11 has an opening near the upper end, the upper end of which forms an abutment 15. Shortly before the telescopic rod 12 is completely pulled out of the telescopic tube, the free end piece of the leaf spring 14 can pus in the opening and abut against the abutment 15. The free end piece of the leaf spring 14 acts as a clamping member 16 as soon as the telescopic rod is pushed a little further than FIG. 3 into the telescopic tube.
