METHOD FOR DETERMINING THE LACK OF CONTINUITY IN THE INTERSTITIAL SPACE OF DOUBLE-WALLED RESERVOIRS

摘要

Such reservoirs comprise, in principle, an outer wall (1), an inner wall (2) defined by a translucent layer of material, and an intermediate layer (3) formed by a three-dimensional fabric (4) combined with an interstitial space (5). The invention is characterised in that a light source (7) is applied to the layer of translucent material (2), crossing same until it reaches the intermediate layer (3), in such a way that the projection of the emitted light bounces back off an inner face (11) of the outer wall (1) which is in contact with the intermediate layer (3), generating a reflection (9) of the light that creates an aura (8) on the outside, that defines a visible contour line in the projection thereof when the presence of a solid accumulation of material (6) is detected inside the interstitial space (5) of said intermediate layer (3).
