Composite three-rib filtering reinforced drainage net and preparation method thereof
The invention relates to technical application of geotechnical materials, in particular to a composite three-rib filtering reinforced drainage net and a preparation method thereof. The composite three-rib filtering reinforced drainage net comprises a three-rib geonet core, a permeable non-woven geotextile layer and a waterproof geotextile layer; the permeable non-woven geotextile layer and the waterproof geotextile layer are fixedly arranged at the two sides of the three-rib geonet core respectively; and the three-rib geonet core is obtained by mixing and melting high-density polyethylene, an ethylene-vinyl acetate copolymer, metallocene polyethylene, polyethylene, and an anti-aging agent to form a modified high polymer, extruding the modified high polymer into filaments to obtain H-shaped special-shaped ribs, and weaving the H-shaped special-shaped ribs. The composite three-rib filtering reinforced drainage net can quickly drain accumulated water, is a gap maintenance system, can block capillary water under high load, and plays roles in isolation and reinforcement at the same time.
本发明涉及土工材料技术应用，具体涉及一种复合型三肋过滤增强排水网及其制备方法。所述复合型三肋过滤增强排水网包括三肋土工网芯、透水无纺土工布层和防水土工布层，所述透水无纺土工布层和防水土工布层分别固定设置在三肋土工网芯的两侧；所述三肋土工网芯由高密度聚乙烯、乙烯‑醋酸乙烯共聚物、茂金属聚乙烯、聚乙烯和抗老化剂混合熔化形成改性高聚合物，经挤压成丝获得H型异型肋条，再经编织获得；该排水网能够迅速地排出积水，同时自身是一个空隙维护系统，能在高载荷下阻断毛细水，同时起到隔离和加固作用。
