Composite coarse-denier long hot-melt net core filtering enhanced drainage geotextile mat and preparation method thereof
The invention relates to technical application of geotechnical materials, in particular to a composite coarse-denier long hot-melt net core filtering enhanced drainage geotechnical mat and a preparation method thereof. According to the geotextile mat, various polymer fibers are compounded to form a three-dimensional fiber net, various resin materials are subjected to high-temperature melting, extrusion spinning, cooling, disordered wire net laying and melting reinforcing forming to obtain a coarse-denier long hot melting net core, and the three-dimensional fiber net and the net core are compounded to obtain the filtering enhanced drainage mat. The drainage mat is high in pressure resistance, large in porosity, capable of accumulating water in all directions and capable of draining water horizontally and vertically; under a closed covering layer buried by soil, rainwater which is collected and permeates through the covering layer or sewage discharged by a storage yard can be discharged to a drainage ditch, soil can be protected against loss and clogging, and the effect of reinforcing the soil is achieved; and construction is convenient, and cost is low.
本发明涉及土工材料技术应用，具体涉及一种复合型粗旦长热熔网芯过滤增强排水土工席垫及其制备方法。该土工席垫以多种聚合物纤维复合形成三维纤维网，并以多种树脂材料经高温熔融、挤压纺丝、冷却、乱丝铺网、熔融加固成型获得粗旦长热熔网芯，将三维纤维网与网芯复合获得过滤增强排水席垫，该排水席垫耐压高、孔隙率大、全方位积水、水平垂直排水；能在土壤掩埋的封闭覆盖层之下，将汇集渗透过覆盖层的雨水或堆场本身排放的污水排出于排水沟，且能保护土壤不流失，不淤堵，并起加固土壤作用；施工方便，成本低。
