TH21522B - Geotextile filter structure - Google Patents

Abstract

DC60 (01/10/41) invention of this Related to the structure of geotextiles, the use of geotextiles, which consists of - the lower layer (12) of the geotextile material For filtering appear the number One of the n-band contractions is included between 15 and 40 and is made up of strands or fibers. The synthesis appears bowed D (decitex decitex) and the top-layer (14) of geotextile materials. For protection Which phenomenon Shrink the fasteners that open over the bottom layer. And made up of fibers and synthetic fibers Where the count values are at least equal to those upper and lower 2D (decitex) levels And connect with each other This invention Related to the structure of geotextiles, the use of geotextiles, which consists of - the lower layer (12) of the geotextile material For filtering appear the number One of the n-band contractions is included between 15 and 40 and is made up of strands or fibers. The synthesis appears bowed D (decitex decitex) and the top-layer (14) of geotextile materials. For protection Phenomenal Shrink the fasteners that open over the bottom layer. And made up of fibers and synthetic fibers It turns out that it counts at least the same as the top and bottom 2D (decitex) above. And connect with each other

Claims (5)

1. Geotextile structures are used for filtration of liquid from soil. It has the characteristics that it consists of - the lower layer (12) of the tubular material used for filtration with a certain thickness of n shrinkage that is included between 15 and 40 and is made of fibers or synthetic fibers. There is a count value D (decitex) and - the upper layer (14) of the textile material. Geologically used for mechanical protection. That are in the thickness of the Shrink the band open rather than shrink the lower strapping to avoid clogging the bottom layer. And made of fiber or synthetic with a count of at least 2D, the top and bottom layers are welded to. With each other 2. Structures of geo-pipelines According to claim 1, it is characterized by that the amount of constriction of the lower layers (12) is included between 20 and 35. 3. Geotextile structures According to claim 1 or 2, which has a special characteristic that the count of the fiber of the upper layer Is integrated between 3D and 4D. 4. Geotextile structures are used according to any of the clauses 1 to 3, which has the effect that the lower layers are made of fibers that count between 3 and 5 decitex and that the upper layers are made of Fiber The value counts between 12 and 20 decitex. 5. Geotextiles are geologically applied according to any of the clauses 1 to 4, characterized by the fact that the upper layer has a mass per face, adjusted to the degree of protection required.
