Využití oscilujících vodních paprsků při odstraňování povrchových vrstev degradovaného betonu in situ
The effects of aggressive environment, the use of the structure during the course of time and the loads induced by the operation can lead to damages. Transport structures (roads, tunnels, bridges) belong among highly exposed concrete structures (through cyclic loading, climatic conditions, application of thawing chemicals, actions of fires etc.). The already damaged structures have to be returned to an operational condition in the shortest possible time.The rehabilitation of concretestructures requires a defective concrete layer is removed on the basis of an expert assessment and design and the defective parts of the structure are replaced. The removal of defective layers therefore represents an important stage during the course of the rehabilitation and maintenance of concrete structures. Apart from traditional methods, such as cutting off, breaking by jack hammers, dry or wet sand blasting, flame cleaning and milling, ever more technologies used to this purpose are based on high-velocity waterjets. In our country the use of waterjets is recommended, whilst in some countries (e.g. Germany) it is, owing to the unique properties of waterjets,even required.
