    长丝仿粘针刺非织造土工布性能特点:

    1.过滤(反滤)作用:在使液体通过的同事,保持住受液力作用的土或其他颗粒

    2.隔离作用:使两种或多种材料间不流失、不混杂。保持材料的整体结构和功能,使构筑物荷载承受能力加强。

    3.排水作用: 土工布是良好的导水材料, 它可以在土体结构形成排水通道,将土体结构内部多余的液体和气体排出。

    4.加筋作用,将土工布埋置于软基或不稳定的土体中可以起到加筋作用,从而提高土体的整体强度和稳定性。

    5.防护作用:有效地将集中应力扩散、传递或分解,防止土体受外力作用而被破坏。

    长丝仿粘针刺非织造土工布用途:

    水利工程堤坝及护坡的反滤,渠道的隔离、防渗。公路、铁路、机场跑道的基础隔离、反滤、排水、土坡、挡土墙及路面加筋、排水。港口工程的软基处理,海滩围堤、海港码头及防坡堤加筋、排水。长丝土工布已普遍应用于基础设施建设领域,逐步被应用于更广泛的领域。
