GEOSYNTHETIC MATERIAL FOR A DEVICE FOR REINFORCING GROUND AT RISK OF COLLAPSE

摘要

THE INVENTION RELATES TO A REINFORCING DEVICE FOR A GEOSYNTHETIC MATERIAL (10) WHICH COMPRISES AT LEAST ONE LAP OF PARALLEL STRANDS (11, 12). THESE REINFORCING STRANDS ARE DISTRIBUTED IN A FIRST GROUP OF STRANDS (11), PRODUCED WITH A FIBRE HAVING A HIGH TENSION MODULUS AND A BREAKING ELONGATION, PRODUCED WITH A FIBRE HAVING A TENSION MODULUS BELOW THE TENSION MODULUS OF THE FIBRE OF THE FIRST GROUP OF STRANDS AND A BREAKING ELONGATION VALUE AT LEAST EQUAL TO 12THE FIBRE OF THE STRANDS OF THE FIRST GROUP IS MADE OF POLYVINYL ACETATE.(FIG. 1)
