Road subgrade global hydrophobic-waterproof composite three-dimensional geomembrane
The invention discloses a road subgrade global hydrophobic-waterproof composite three-dimensional geomembrane, belongs to the technical field of pavement maintenance, and aims to solve the problems ofroadbed water immersion and frost heaving. The composite three-dimensional geomembrane is composed of three layers, the upper layer includes a common glass fiber net or a loose treatment glass fibernet, the middle layer includes a macromolecule polyethylene native resin impermeable membrane, and the lower layer includes a loose treatment glass fiber net. When the composite membrane is laid in aroadbed, the rising height of underground water can be blocked, the range of soil in which frost heaving participates is reduced, capillary water in the roadbed can be discharged as soon as possible,the composite membrane can be effectively combined into an edge drainage system by properly extending the composite membrane, and therefore the requirement for a roadbed filler can be properly lowered, and the using number of selected materials is reduced. When the composite membrane is laid between a cushion layer and the roadbed, the cushion layer can play a more prominent role, cushion layer drainage only aims at upper water seepage, and meanwhile the drainage efficiency can be improved through the special design of the composite membrane.
一种道路路基全域疏水‑阻水复合三维土工膜，属于路面维护技术领域。本发明的目的是为了解决路基水浸及冻胀的问题，所述复合三维土工膜由三层组成，上层为普通玻璃纤维网或疏松处置玻璃纤维网，中间层为高分子聚乙烯原生树脂防渗膜，下层为疏松处置玻璃纤维网。该复合膜铺设在路基内部时，可阻断地下水上升高度，减少冻胀参与的土体范围，可尽早排除路基内部毛细水，适当延伸复合膜可有效地结合到边缘排水系统中，这样路基填料的要求可适当降低，精选材料的使用数量减少。该复合膜铺设在垫层和路基之间时，可使得垫层作用更加突出，垫层排水仅针对上部渗水，同时复合膜的特殊设计可增大排水效率。
