The gauge of the deformation for layers geosynthetics and geomembranes

摘要

The present invention relates to a deformation measurement gauge for construction fabric sheets, using a resistive element. This gauge is characterised in that it comprises two rigid and strong lateral plates 3, 4, fixed to the construction fabric sheet, separated from each other, and a resistive element 7, such as a wire, extending between the two plates 3, 4 to which it is fixed, and whose change in resistance, corresponding to its change in extension, is measured.
