Abstract

L'invention se rapporte au domaine de la construction et peut être utilisée pour un dispositif de systèmes de drainage de divers types, un dispositif de couches intermédiaires de protection-filtration et de renfort dans des terre-pleins sur des sols meubles et dans des conditions de sols et géologiques complexes et des fondations de revêtements routiers, etc. Ce géotextile tissé filtrant se présente sous forme d'une bande avec une tresse en bande et de serge de fils faits de polypropylène ayant un indice d'écoulement à l'état fondu de 3-5 g/10 min. avec un ajout d'additif anti-fibrillation de carbonate de calcium et un stabilisant UV; on utilise sur la trame des fils ayant une densité linéaire de 700-6000 deniers et une largeur de 4-12 mm avec un taux de fibrillation élevé et, sur la base, on utilise des fils plans ayant une densité linéaire de 1000-4000 deniers et une largeur de 1-4 mm; le coefficient de filtration du géotextile est de 40 m/jour à une pression de 100-200 kPa. Le résultat technique consiste en une augmentation de la capacité de passage de l'eau du système de drainage de 1,5 - 2,5 fois sur lequel il est installé.
