Description

Instandsetzung schadhafter Talsperrenmauern Es ist bekannt, Staumauern dadurch instand zu setzen und abzudichten, daß auf der Wasserseite nach vorhergehender Reinigung der !Mauerfläche ein wasserdichter, gegebenenfalls durch eine Bevve.@hrung verstärkter Mörtelputz aufgebracht wird, der das dem Mauerkern schadenbringende weiche und kohlensäurehaltige Wasser von diesem abriegeln soll. Durch das Verfahren gemäß der Erfindung soll die Rissesicherheit eines derartigen wasserdichten Putzes und damit die Lebensdauer von Staumauern erhöht werden.Repair of damaged dam walls It is known, dam walls by repairing and sealing that on the water side after the previous one Clean the wall surface with a watertight, if necessary by means of a Bev. @Hrung Reinforced mortar plaster is applied, which damages the wall core Soft and carbonated water is supposed to shut off from this. Through the procedure According to the invention, the crack resistance of such a waterproof plaster should be and thus the lifespan of dams can be increased.

Zu diesem Zweck werden; nach der Erfindung in die Mauer in Abständen; die dem Ausdehnungskoeffizienten des Dichtungsmörtels angepaßt sind, waagerecht und senkrecht verlaufende, im Querschnitt schwalbenschwanzförmige Fugen eingearbeitet, hierauf werden von Fugenrand zu Fugenrand sich erstreckende Bewehrungseinlagen angeordnet, und anschließend wird die Mauerfläche einschließlich der Flächen in den Fugen mit einem Mörtelputz' von überall gleichbleibender Stärke überzogen, worauf der in den Fugen verbleibende IHohlnaum mit Asphalt ausgefüllt wird.To this end will be; according to the invention in the wall at intervals; which are adapted to the expansion coefficient of the sealing mortar, horizontally and vertically running, dovetail-shaped joints in cross-section, on this, reinforcement inserts extending from joint edge to joint edge are arranged, and then the wall surface including the surfaces in the joints with a mortar plaster 'of constant thickness everywhere, whereupon the in the Joints remaining in the hollow space is filled with asphalt.

Nach einem Ausführungsbeispiel der Erfindung geht der Ausbesserungsvorgang wie folgt vor sich: Nach vorgenommener Ahsenlku.ng des Wassers findet eine Reinigung der Mauerflächen durch Abwaschen, Absäuren und Abblasen mit dem Sandstrahl statt. Pro Quadratmeter Wandfläche werden aldann einige Eisendübel etwa 30 cm tief in die Mauer eintorkretiert, an die dann ein Baustahlgewebe mit i cm Abstand vor der Mauer angebracht wird. Nun wird .die ganze Fläche mit einem etwa 5 cm starken Torkretfllm entsprechender Zusammensetzung versehen. Um der Möglichkeit von Rissebildungen infolge der unvermeidlichen Auisdehnurig und Zusammenziehung des Tonkretputzes vorzubeugen, werden schwallbenschwanzförmige Dehnungsfugen horizontal und vertikal angeordnet, deren Entfernung voneinander sich dem ermittelten Mörtelausdehnungskoeffizienten anpaßt. Die Dehnungsfugen werden in das Betonmauerwerk eingemeißelt, und der Torkretputz wird in seiner vorgesehenen Stärke über die Fugen hinweg eingebracht. Er kann sich infolge der vorliegenden Formgebung der Dehnungsfugen ausdehnen und zusammenziehen, ohne daß Risse und damit Undichtigkeiten in der torkretierten Fläche entstehen. Die Wände des verbleibenden schwalbenschwanzförmigen Hohlraumes in der Dehnungsfuge werden mit Bitumen gestrichen, und der Hohlraum wird mit Asphaltmasse gefüllt und letztere verdichtet.According to one embodiment of the invention, the repair process proceeds as follows: After the water has been removed, the wall surfaces are cleaned by washing, acidifying and blowing with the sandblast. For every square meter of wall surface, a few iron dowels are then crammed into the wall about 30 cm deep, to which a structural steel mesh is then attached at a distance of 1 cm in front of the wall. Now the whole area is provided with an approximately 5 cm thick Torkretfllm of the appropriate composition. In order to prevent the possibility of crack formation as a result of the inevitable external expansion and contraction of the clay plaster, dovetail-shaped expansion joints are arranged horizontally and vertically, the distance between them being adapted to the determined mortar expansion coefficient. The expansion joints are chiseled into the concrete masonry and the Torkret plaster is applied over the joints in its intended thickness. It can expand and contract as a result of the existing shape of the expansion joints without cracks and thus leaks occurring in the door-locked surface. The walls of the remaining dovetail-shaped cavity in the expansion joint are painted with bitumen, and the cavity is filled with asphalt mass and the latter is compacted.
