Abstract

L'invention concerne un procédé de réduction du frittage des conduites de drainage dans des systèmes de drainage d'ouvrages, tels que des tunnels de voies ferrées ou routiers ou similaires, par stabilisation de la dureté de l'eau de drainage. Le procédé consiste à déposer des sacs de pierres de dépôt issues d'un matériau perméable à l'eau et réticulé dans la/les conduite(s) de drainage, dans des positions de conditionnement sélectionnées, ces sacs étant remplis de pierres de dépôt en vrac ayant une teneur en polysuccinimide qui sert d'agent de conditionnement, le polysuccinimide étant dissous peu à peu par l'eau de drainage qui traverse le/les sac(s) de pierres de dépôt, avec transformation hydrolytique au moins partielle en acide polyaspartique, et l'agent étant ainsi libéré successivement. Le procédé est caractérisé en ce que les sacs de pierres de dépôt sont déposés ou empilés à l'intérieur de la section transversale libre essentiellement circulaire de la/des conduite(s) de drainage, de telle sorte que la section transversale de conduite de drainage soit remplie de sacs de pierres de dépôt dans le sens longitudinal de la conduite de drainage au moins sur une longueur de 10 cm et sur une hauteur de remplissage d'au moins 5 % du diamètre interne.
