beim Schildvortrieb.in shield tunneling.
Beim Auffahren von Tunneln mit Schildvortrieb wurde bisher die' Tunneldecke in einem Zuge hergestellt, wobei die Decke aus einzelnen Betonbalken zusammengesetzt, ist. Über diese Betonbalken wird eine dünne Schutzschicht gelegt, die das Durchfallen von Sand in den Tunnel während des Einbauens der Balken verhütet. Gegenstand der . Erfindung ist ein' Verfahren zum HerstellenWhen driving tunnels with shield driving, the 'tunnel ceiling in produced in one train, the ceiling being composed of individual concrete beams. A thin protective layer is placed over these concrete beams to prevent them from falling through of sand in the tunnel during the installation of the joists. Subject of . Invention is a 'method of manufacturing
ίο einer Decke für Unterpflastertunnel beim Schildvortrieb, bei welchem die' schweren Betonbalken vermieden werden und sowohl . die Decke als auch das Tragwerk leichter ausgeführt wird. Das Neue besteht darin, daß unter dem Schutz des Schwanzendes des Schildes zunächst eine Schutzdecke einstwei-7 Ug abgestützt wird, alsdann die endgültigen Deckenträger eingezogen und nach schrittweisem Vorschieben des Schildes, mit derίο a ceiling for underpaved tunnels for shield driving, in which the 'heavy concrete beams are avoided and both. the ceiling and the supporting structure are made lighter. The novelty consists in that under the protection of the tail end of the shield initially einstwei- a protective cover 7 Ug is supported, the final floor beams and then retracted by stepwise advancing of the shield, with the
ao · Schutzdecke nach oben gegen die Straßendecke gepreßt werden, worauf die Tunnelwände hochgeführt und die endgültige Tunneldecke zwischen den Deckenträgern eingebaut wird. Die Schutzdecke besteht dabei . aus zwei oder mehreren Lagen- von Betonoder Eisenbetonplatteh mit zwischengelegter Dichtung, von denen die oberen Betonplatten durch Haken und Ösen miteinander verbunden sind.ao · protective cover pressed up against the road surface, whereupon the tunnel walls raised and the final tunnel ceiling installed between the ceiling beams will. The protective cover exists. from two or more layers of concrete or Reinforced concrete slab with an interposed seal, of which the upper concrete slabs are connected to each other by hooks and eyes.
Die Figuren der Zeichnung geben ein Bild der zur Ausübung des Verfahrens nötigen Einrichtung. ,The figures in the drawing give a picture of the things necessary to carry out the process Furnishings. ,
Mit α (Fig. 1) ist das Schwanzende des Schildes bezeichnet, das schrittweise vorgeschoben wird. Nach jedesmaligem Vorschieben wird eine Anzahl von Betonplatten b untergeschoben. Diese Platten enthalten beispielsweise,, wie in Fig. 2 dargestellt ist, Eisenstäbe, die an ihren Enden mit Haken und Ösen versehen sind. Die Stäbe endigen an ihrer einen Seite in einer Aussparung der Betonplatte b, so daß es möglich ist, die neü~~ ■ eingeschobenen Platten fest und dicht mit den vorhergehenden zu verbinden. Durch diese Verbindung, die natürlich auch durch andere Mittel bewerkstelligt werden kann, wird ein Mitnehmen der einzelnen Platten beim Vorschieben des Schildes α verhindert und gleichzeitig ein Auflager der zuletzt eingelegten ' Plattenreihe an der vorhergehenden geschaffen. Unter die Betonplattendecke b wird eine Dichtung c geklebt. Alsdann wird eine Reihe starker tragfähiger Eisenbetonplatten d mit Mörtelfuge derart untergelegt, daß ein Halt durch die Behelfsträger e und Keile / erzielt wird. Wenn etwa vier ■ Eisenbetonplatten oder Felder d eingebracht sind, werden die endgültigen starken Träger g eingezogen und durch Bauschrauben h gehalten.With α (Fig. 1) the tail end of the shield is referred to, which is advanced step by step. After each advance a number of concrete slabs b is pushed under. These plates contain, for example, as shown in FIG. 2, iron rods which are provided with hooks and eyes at their ends. The rods end on one side in a recess in the concrete slab b, so that it is possible to connect the newly inserted slabs firmly and tightly to the previous ones. By this connection, which of course can be accomplished by other means, a take-away of the individual plates is α prevented during advancement of the shield, while creating a support of the most recently loaded 'plate number to the previous one. A seal c is glued under the concrete slab ceiling b. A number of strong, stable reinforced concrete slabs d with a mortar joint are then placed underneath in such a way that support is achieved by the temporary supports e and wedges /. When about four reinforced concrete slabs or fields d have been introduced, the final strong girders g are drawn in and held in place by construction screws h .
Um den beim Vorschieben des Schwanzendes α des Schildes entstandenen Hohlraum k zwischen Straßendecke und den Platten d zu beseitigen, werden die Bauschrauben h angezogen und die Schutzdecke nach oben gegen die Straßendecke gepreßt. . In order to eliminate the cavity k between the pavement and the plates d that arises when the tail end α of the shield is pushed forward, the construction screws h are tightened and the protective sheet is pressed upwards against the pavement. .
Beim Aufführen der Tunnelwände werden die Träger g ordnungsmäßig -eingebaut und alsdann die Bauschrauben h entfernt.When the tunnel walls are installed, the girders g are properly installed and then the construction screws h are removed.
Ist die Decke auf diese Art in die richtige Lage gebracht, so werden die Gewölbeformstücke i, die aus Beton, Backsteinen, Steingut oder einem anderen Baustoff bestehen können, zwischen den Deckenträgern g eingebaut und alsdann der entstandene Hohlraum m mit Beton ausgefüllt. If the ceiling is brought into the correct position in this way, the vaulted pieces i, which can consist of concrete, bricks, earthenware or another building material, are installed between the ceiling girders g and the resulting cavity m is then filled with concrete.
