Es zeigen:Show it:

Figuren 1 und 2 je vier Schritte eines Verlegeverfahrens einer Ausführung einer erfindungsgemäßen Brücke.Figures 1 and 2 each four steps of a laying process of an embodiment of a bridge according to the invention.

Figur 1 zeigt ein Hindernis mit einem linken Ufer 2 und einem rechten Ufer 4, wobei am.linken Ufer 2 wegen einer Böschung 6 nur relativ wenig Platz zur Verfügung steht. Etwas außerhalb der Mitte des Hindernisses, näher am rechten Ufer 4, wird eine Stütze 8 aufgestellt, die hier ä als Gittermast mit seitlicher Abspannung ausgeführt ist. Die Stütze 8 weist an ihrem oberen Ende ein Auflager 10 auf, das durch eine in vertikaler Richtung verstellbare Einrichtung 12 (Hydrozylinder, Spindel) höhenverstellbar ist und auf dem sowohl der Vorbauträger der Brücke als auch die Brückenabschnitte selbst längsverschiebbar sind (z.B. überrollen).Figure 1 shows an obstacle with a left bank 2 and a right bank 4, with the left bank 2 because of an embankment 6 there is only relatively little space available. Somewhat outside the middle of the obstacle, closer to the right bank 4, a support 8 is erected, which is designed here as a lattice mast with lateral bracing. The support 8 has at its upper end a support 10 which is adjustable in height by means of a device 12 which can be adjusted in the vertical direction (hydraulic cylinder, spindle) and on which both the stem of the bridge and the bridge sections themselves can be moved longitudinally (e.g. roll over).

Im ersten (obersten) Figurenteil steht am linken Ufer 2 ein an sich bekanntes Verlegefahrzeug 14 mit Verlegebalken 16, das gerade einen Vorbauträger 18 auslegt, der hier auf fünf 7m langen Vorbauträgerabschnitten 20 und aus einem Vorbauträgerrampenteil 22 besteht. An der Spitze des Vorbauträgers 18 ist ein Uferbalken 24 befestigt, der als Auflager für die Brücke am rechten Ufer 4 vorgesehen ist. Die Vorbauträgerabschnitte 20 sind in an sich bekannter Weise auf den Verlegebalken 16 gehoben, zusammengekuppelt und vorgeschoben worden.In the first (uppermost) part of the figure, on the left bank 2, there is a laying vehicle 14, known per se, with laying bar 16, which is currently laying out a front-end girder 18, which here consists of five 7-m long front-end girder sections 20 and a front-end girder ramp part 22. At the top of the stem support 18, a bank beam 24 is attached, which is provided as a support for the bridge on the right bank 4. The stem support sections 20 have been lifted onto the laying beam 16 in a manner known per se, coupled together and advanced.

Im zweiten Figurenteil ist der Verlegebalken 16 abgesenkt worden und der vorderste Abschnitt des Vorbauträgers 18 liegt auf dem Auflager 10 der Stütze 8. 5In the second part of the figure, the laying beam 16 has been lowered and the foremost section of the stem support 18 lies on the support 10 of the support 8. 5

Im dritten Figurenteil ist der Vorbauträger 18 mit Hilfe des am Fahrzeug 14 befestigten Krans 26 - der in den beiden oberen Figurenteilen nicht gezeigt ist - am linken Ufer 2 auf einen zweiten Uferbalken 28 abgesetzt. Die hintere Abstützvorrichtung und der Verlegebalken 16 des Verlegefahrzeugs 14 sind dabei eingefahren. Der Vorbauträger 18 liegt nun zwischen Uferbalken 28 und Auflager 10.In the third part of the figure, the front carrier 18 is by means of the crane 26 attached to the vehicle 14 - which is not shown in the two upper parts of the figure - deposited on the left bank 2 on a second bank beam 28. The rear support device and the laying beam 16 of the laying vehicle 14 are retracted. The stem support 18 now lies between the bank beam 28 and the support 10.

Im vierten Figurenteil sind ein Brückenrampenteil 30 und mehrere Brückenabschnitte 32 auf den Vorbauträger 18 aufgelegt, zusammengekuppelt und vorgetrieben worden, bis das Brückenrampenteil 30 die Stütze 8 erreicht hat. Dort wird der Uferbalken 24 vom Vorbauträgerrampenteil 22 gelöst und am Brückenrampenteil 30 befestigt.In the fourth part of the figure, a bridge ramp part 30 and a plurality of bridge sections 32 are placed on the stem support 18, coupled together and driven forward until the bridge ramp part 30 has reached the support 8. There, the bank beam 24 is detached from the porch girder ramp part 22 and attached to the bridge ramp part 30.

Figur 2 zeigt die nächsten Schritte des Verlegevorgangs: Im ersten (obersten) Figurenteil ist die Brücke durch weiteres Anfügen von Brückenabschnitten 32 verlängert undsoweit vorgetrieben worden, bis der Schwerpunkt 34 der Brücke noch einige Meter vor der Stütze 8 liegt. Dann wird noch ein Brückenabschnitt 32 angekuppelt.FIG. 2 shows the next steps of the laying process: in the first (top) part of the figure, the bridge has been extended by further adding bridge sections 32 and has been advanced until the center of gravity 34 of the bridge is still a few meters in front of the support 8. Then a bridge section 32 is coupled.

Im zweiten Figurenteil hat das Verlegefahrzeug 14 nach links gesetzt, möglich wäre auch, bei engeren Platzverhältnissen, ein Versatz nach hinten in Längsrichtung des Hindernisses, so daß auf jeden Fall vor dem Uferbalken 24 noch Platz für das Brückenrampenteil 30 (ebenfalls ca. 7 m) bleibt. Es wird jetzt noch ein Brückenrampenteil 30 angekuppelt. Die Brücke hat jetzt ihre volle Länge erreicht.In the second part of the figure, the laying vehicle 14 has set to the left; it would also be possible if space was tight ratios, an offset to the rear in the longitudinal direction of the obstacle, so that in any case there is still space for the bridge ramp part 30 (likewise approximately 7 m) in front of the bank beam 24. A bridge ramp part 30 is now coupled. The bridge has now reached its full length.

Im dritten Figurenteil ist die Brücke soweit vorgeschoben, daß sie das rechte Ufer 4 erreicht.In the third part of the figure, the bridge is advanced so far that it reaches the right bank 4.

Im vierten Figurenteil ist das Auflager 10 der Stütze 8 abgelassen worden, die Brücke liegt nun auch auf dem rechten Ufer 4 auf. Die Uferbalken 24, 28 werden ebenfalls in an sich bekannter Weise abgelassen. Schlepprampen 36 werden auf die Uferbalken 24, 28 aufgelegt. Die Brücke ist befahrbar.In the fourth part of the figure, the support 10 of the support 8 has been lowered, the bridge is now also on the right bank 4. The bank beams 24, 28 are also lowered in a manner known per se. Drag ramps 36 are placed on the bank beams 24, 28. The bridge is passable.
