Method for testing the tightness of reinforced concrete tanks and reinforced concrete tanks for carrying out the method

摘要

The invention relates to a method for leak testing of reinforced concrete containers by means of perforated injection hose, wherein a component of the container with a test page by building a formwork and a reinforcement, then introducing concrete, the curing of the concrete and removal of the formwork is formed. The object of the invention is to provide a method for leak testing of structures made of reinforced concrete, which already performed shortly after the concrete work and beyond at any time (even during the use phase of the concrete structure) can be repeated. Furthermore, the leak test to achieve a high degree of plausibility, acceptance and accuracy in terms of their statement of tightness and allow no relativization of uncontrollable influences (sunlight, wind, rainfall, etc.). This object is achieved in that the injection hose (9, 11) is laid in an installation space spanned by the reinforcement or on a side of the component opposite the test side, and that at least one end of the injection hose (9, 11) is connected to a tight connection hose (9). 10) is led out of the component or via the tight connection hose (10) outside the component is accessible and that the injection hose (9, 11) embedded in the concrete or is covered by the concrete and that after curing of the concrete a tracer gas is introduced into the injection hose (9, 11) on the connection hose (10) and that the amount of tracer gas emerging at the test side of the component serves as a measure of the tightness of the component. Furthermore, a reinforced concrete container is proposed for carrying out the method.
