Coconut fiber and coconut geotextile composite reinforced expansive soil roadbed and construction method thereof
The invention discloses a coconut fiber and coconut geotextile composite reinforced expansive soil roadbed and a construction method thereof. The coconut fiber and coconut geotextile composite reinforced expansive soil roadbed comprises a foundation layer, a roadbed layer laid on the top surface of the foundation layer and a pavement layer laid on the top surface of the roadbed layer, wherein the roadbed layer comprises a roadbed base body and a plurality of reinforced structure layers; the roadbed base body is formed by mixing and compacting coconut shell fibers and expansive soil, and the reinforced structure layer is mainly composed of coconut shell geotechnical cloth. The expansive soil roadbed mainly solves the problems of poor permeability, water swelling, water loss shrinkage, multiple cracks, humidification and the like of a current expansive soil roadbed, the coconut shell fibers and the coconut shell geotextile are used, the coconut shell fibers and the coconut shell geotextile serve as rib materials, the strength of a soil body is greatly improved, the coconut shell geotextile and the coconut shell fibers are environment-friendly materials, and therefore the expansive soil roadbed is environmentally friendly. And the method plays an important role in protecting the environment and saving resources.
本发明公开了一种椰壳纤维与椰壳土工布复合加筋膨胀土路基及其施工方法，包括：地基层、铺设于地基层顶面的路基层和铺设于路基层顶面的路面层；其中，路基层包括路基基体和多层加筋结构层；路基基体由椰壳纤维和膨胀土混合压实而成，加筋结构层主要由椰壳土工布构成。本发明主要解决了当前膨胀土路基存在的渗透性差、吸水膨胀、失水收缩、多裂隙、湿化等特性，使用椰壳纤维与椰壳土工布，不仅椰壳纤维的掺入与椰壳土工布作为筋材极大的提高了土体的强度，而且椰壳土工布与椰壳纤维均是环保型材料，对环境保护，节约资源具体重大作用。
