Abstract

The present invention relates to a geotextile according to any one of the claims of the main patent no. 84 16 711. According to this addition the geotextile is characterised in that it comprises at least one layer of additional reinforcing threads 40, oriented substantially along the diagonal with respect to the warp and weft threads.

Description

GEOTEXTILE
La présente invention concerne un géotextile du type visé dans la demande de brevet No. 84 lé 771.GEOTEXTILE
The present invention relates to a geotextile of the type referred to in patent application No. 84 lé 771.

Selon le perfectionnement de la présente addition, un géotextile conforme à la revendication 1 de la demande principale est caractérisé en ce qu'il comprend au moins une nappe de fils de renforcement additionnels, orientés sensiblement suivant la diagonale par rapport aux fils de chaine et de trame. According to the improvement of the present addition, a geotextile according to claim 1 of the main application is characterized in that it comprises at least one ply of additional reinforcing threads, oriented substantially along the diagonal with respect to the warp threads and frame.

Ces fils de renforcement sont de préférence de nature différente des fils de chaîne et de trame, c'est-à-dire soit dans leurs caractéristiques physiques, soit dans leur constitution, comme il est exposé dans le brevet principal à propos des fils de channe et de trame. These reinforcing threads are preferably of a different nature from the warp and weft threads, that is to say either in their physical characteristics, or in their constitution, as explained in the main patent with regard to the warp threads. and weft.

Selon un mode de réalisation visé par le présent certificat d'addition, il est prévu deux nappes de fils de renforcement, orientées suivant des diagonales opposées par rapport aux fils de channe et de trame. According to an embodiment referred to in this addition certificate, two layers of reinforcing threads are provided, oriented along opposite diagonals with respect to the warp and weft threads.

Toutes les autres variantes exposées dans le brevet principal peuvent également s'appliquer, notamment le doublage du géotextile par une couche de matériau non-tissé et/ou par une couche de matériau imperméable. All the other variants set out in the main patent can also apply, in particular the lining of the geotextile with a layer of non-woven material and / or with a layer of impermeable material.

Dans ces derniers cas, on disposera la couche de fils (trame, channe ou renforcement) les plus fragiles au contact de la couche de doublage afin de les protéger des agressions mécaniques extérieures. In these latter cases, the most fragile layer of wires (weft, edge or reinforcement) will be placed in contact with the lining layer in order to protect them from external mechanical attack.

La figure unique ci-jointe, semblable à la figure 3b du brevet principal, illustre un géotextile selon la présente addition. The attached single figure, similar to Figure 3b of the main patent, illustrates a geotextile according to the present addition.

En plus des fiLs de trame 10 et de chaîne 20, le géotextile comporte une nappe de fils de renforcement 40, orientée sensiblement suivant la diagonale des fils de chaine et de trame, et maintenus par les mêmes fils de Liaison 30. In addition to the weft 10 and warp threads 20, the geotextile comprises a layer of reinforcing threads 40, oriented substantially along the diagonal of the warp and weft threads, and held by the same connecting threads 30.

Si les fils de chaîne et de trame sont choisis pour Leurs propriétés hydrofuges, tandis que les fils de renforcement sont choisis pour leur propriétés hydrophiles, on observera un écoulement des eaux dans une direction diagonale par rapport à la direction des les de géotextile (fils de chaîne 20).  If the warp and weft threads are chosen for their water-repellent properties, while the reinforcing threads are chosen for their hydrophilic properties, we will observe a flow of water in a diagonal direction relative to the direction of the geotextile chain 20).
