Description
Bei größeren Reparaturen - wenn es nicht um die Ausbes serung von relativ kleinen Schadstellen geht - ist, ins besondere im Straßenbau, entweder das Abfräsen einer rela tiv dünnen Asphalt-Schicht oder die totale Zerstörung - sowohl beim Tiefeinbau als auch beim Hocheinbau - und anschließender Neubau, ggf. unter Verwendung der Reste der alten Straße, üblich. - Vergleiche Scholz, Baustoffkenntnis, 12. Auflage 1991, Werner-Verlag, S. 338.For larger repairs - if it is not the repair of relatively small damaged areas - is, ins especially in road construction, either milling a rela tiv thin asphalt layer or total destruction - both in deep installation and in high installation - and subsequent new building, possibly using the remains of the old street, usual. - Compare Scholz, knowledge of building materials, 12th edition 1991, Werner-Verlag, p. 338.
Der in den Patentansprüchen angegebenen Erfindung liegt das Problem zugrunde, die Ausbesserung von großflächigen Be reichen von Straßen, großen Platten, Kaimauern o. ä. bei Verschleiß oder beim Auftreten von Absenkungen zu verein fachen.The invention specified in the claims lies Problem underlying the repair of large Be range from streets, large slabs, quay walls or similar Wear or when subsidence occurs fold.
Dieses Problem wird durch die in den Patentansprüchen auf geführten Merkmale gelöst.This problem is highlighted in the claims guided characteristics solved.
Die mit der Erfindung erzielten Vorteile bestehen insbe sondere darin, daß der Bereich - im Verhältnis z. B. zum vollständigen Abfräsen der auszubessernden Schicht - ein fach entfernt werden kann.The advantages achieved with the invention are in particular special in that the area - in the ratio z. B. to complete milling of the layer to be repaired - a can be removed.
Das Material kann längs der Sollbruchfläche - z. B. durch Meißeln - ohne großen Energieaufwand abgetrennt werden und zudem entsteht eine Fläche, die nach dem ersten Arbeitsgang ggf. nur wenig nachbearbeitet werden muß.The material can along the predetermined breaking area - z. B. by Chisels - can be separated without much energy and in addition, a surface is created after the first work step may need to be reworked only a little.
Es kann - insbesondere im Falle der Beton-Straße - der vorhandene intakte Unterbau weiterverwendet werden; es muß daher nicht die gesamte Schicht zerstört und wieder erneuert werden.It can - especially in the case of the concrete road - the existing intact substructure can continue to be used; it must therefore not the entire layer destroyed and again to be renewed.
Außer den - langfristigen - Kostenvorteilen ergeben sich im Falle der Ausbesserung von bestehenden Autobahnen, Straßen, Flugplätzen o. ä. geringere Reparaturzeiten als bei vollständigem Abbruch und anschließender Wiederherstellung.In addition to the - long-term - cost advantages in case of repair of existing highways, Roads, airfields or similar shorter repair times than at complete abort and subsequent recovery.
Die Darstellung erfolgt beispielhaft für die mehrschichtige Beton-Bauweise in Verbindung mit Patentanspruch 5:The representation is exemplary for the multilayer Concrete construction in connection with claim 5:
Die untersten Betonschichten werden wie üblich aufgebracht und verdichtet, auf die oberste dieser Schichten wird - ge mäß Patentanspruch 5 - ein feinmaschiges, dünnes Netz, das z. B. aus Kunststoff bestehen kann, aufgebracht und darauf mindestens eine weitere Betonschicht, die wie üblich ver dichtet und mit einem Stahlbesen abgezogen werden kann.The bottom concrete layers are applied as usual and condensed, the top of these layers is - ge according to claim 5 - a fine-mesh, thin network that e.g. B. can be made of plastic, applied and on it at least one additional layer of concrete, which ver seals and can be removed with a steel broom.
Die geringfügig verringerte Festigkeit, die durch die Ein bettung des Körpers entsteht, kann, falls erforderlich, ausgeglichen werden, indem z. B. die Schichtdicken gegenüber der herkömmlichen Bauweise unwesentlich vergrößert werden.The slightly reduced strength caused by the one bedding of the body arises, if necessary, can be compensated by z. B. compared to the layer thicknesses the conventional construction can be enlarged insignificantly.
Wenn nach späterem Verschleiß insbesondere große Teile der Fläche erneuert werden sollen, so wird die oberste Schicht durch Meißeln entlang des Netzes - in dieser Ebene, die eine Sollbruchfläche bildet, platzt der Beton leicht auf - entfernt.If especially large parts of the Surface to be renewed, so the top layer by chiseling along the net - in this plane, the forms a predetermined breaking surface, the concrete bursts easily - away.
Auf die oberste der bestehenden Schichten kann - wie oben beschrieben - wieder die Deckschicht aufgebracht werden.The top of the existing layers can - as above described - the top layer can be applied again.
Dabei ist darauf zu achten, daß das neu aufgebrachte Material nach dem Erhärten ähnliche Eigenschaften wie die unteren Schichten aufweisen, damit sich die Schichten dauerhaft miteinander verbinden können.It is important to ensure that the newly applied Material after hardening similar properties to that have lower layers so the layers can connect with each other permanently.
Natürlich bleibt die Möglichkeit der üblichen Ausbesserung von Schäden auch bei Herstellung nach dem vorgeschlagenen Verfahren bestehen.Of course, the possibility of the usual touch-up remains of damage even when manufactured according to the proposed Procedures exist.
