Concrete pipe watertightness testing station - has chuck arrangement accommodating different sizes of concrete or reinforced concrete pipe

摘要

The station is used for testing the watertightness of ducts and conduits (a) in concrete and reinforced concrete and requires only one laboratory assistant. It enables repetitive cycles to be carried out rapidly without water consumption. The rapidity of control and the arrangement of several chucks (d) enables ducts and conduits (a) of different diameters to be included in the same series of tests. The refilling water is introduced and removed in several seconds and is permanently recycled. The use of a bath (j) with a scale (k) permits, not only measurement of pressure but also of any loss of water from the test elements.
