    塑料单向土工格栅作用用途:

    1、 单向土工格栅用于加固软弱地基:土工格栅能迅速提高地基承载力,控制沉降量的发展,对道路基层的侧限作用能有效地将荷载分布到更宽的底基层上,从而减少基层厚度,降低工程造价,缩短工期,延长使用寿命。

    2、 单向土工格栅用于水泥路面:土工格栅铺设在水泥铺层底部,可减少车辙深度,延长路面抗疲劳寿命,还可以减少水泥铺面厚度,以节约成本。

    3、
    单向土工格栅用于加固路堤坝迦坡及挡土墙:传统的路堤尤其是高路堤的填筑往往需要超填且路肩边缘不易压实,从而导致后期边坡雨水浸袭,坍塌失稳的现象时有发生,同时需用较缓的边坡,占地面积大,挡土墙也有同样的问题,采用土工格栅对路堤边坡或挡土墙进行加固可减少二分一占地面积,延长使用寿命,降低造价20—50%。

    4、 单向土工格栅用于加固江河海堤:可做成石笼,再与格栅并用,防止堤坝被海水冲刷造成塌陷,石笼具有渗透性,能减缓海浪冲击,延长堤坝寿命,节省人力物力,缩短工期。

    5、 单向土工格栅用于处理垃圾掩埋场:土工格栅与其它土合成材料结合使用处理垃圾掩埋场,可以有效地解决地基不均匀沉降、衍生气体排放等问题,且可最大限度地提高垃圾掩埋场的存储能力。

    6、 单向土工格栅的特殊用途:抗低温性。抗低温土工格栅,在—45℃–—50℃反复冷热循环200次后,各项性能指标均满足要求,并已经过青藏铁路的考验,适用于北方的少冰冻土、富冰冻土、高含冰量冻土不良地质。
