    Description

    塑料双向土工格栅是经过拉伸形成的具有方形或矩形的聚合物网材,按其制造时拉伸方向的不同可为单向拉伸和双向拉伸两种。它是在经挤压制出的聚合物板材(原料多为聚丙烯或高密度聚乙烯)上冲孔,然后在加热条件下施行定向拉伸。单
    向拉伸格栅只沿板材长度方向拉伸制成,而双向拉伸 格栅则是继续将单向拉伸的格栅再在与其长度垂直的方向拉伸制成。

    由于塑料双向土工格栅在制造中聚合物的高分子会随加热延伸过程而重新排列定向,加强了分子链间的联结力,达到了提高其强度的目的。其延伸率只有原板材的10%~15%。如果在土工格栅中加入炭黑等抗老化材料,可使其具有较好的耐酸、耐碱、耐腐蚀和抗老化等耐久性能。

    塑料双向土工格栅是用高分子聚合物通过挤压、成板、冲孔过程后再纵向、横向拉伸而成。该材料在纵向和横向上都具有很大的拉伸强度,这种结构在土壤中同样也能提供一个更为有效的力的承担和扩散的理想的连锁系统,适应于大面积永久性承载的地基

    塑料双向土工格栅用途:塑料双向格栅适用于各种堤坝和路基补强、边坡防护、洞壁补强,大型机场、停车场、码头货场等永久性承载的地基补强。

    1. 增大路(地)基的承载力,延长路(地)基的使用寿命。

    2. 防止路(地)面塌陷或产生裂纹,保持地面美观整齐。

    3. 施工方便,省时,省力,缩短工期,减少维修费用。

    4. 防止涵洞产生裂纹。

    5. 增强土坡,防止水土流失。

    6. 减少垫层厚度,节约造价。

    7. 支撑边坡植草网垫的稳定性绿化环境。

    8. 可取代金属网,用于煤矿井下假顶网。

    塑料双向土工格栅的施工方法:

    塑料双向格栅当用于路基、路面时,开挖基床,设置砂垫层(高差不大于10cm),碾压成平台,铺设格栅,纵轴向应与主要受力方向一致,纵向搭接15-20cm,横向10cm,搭接处用塑料带绑扎,并在铺设的格栅上,每隔1.5-2m用U型钉固定于地面,铺设的土工格栅应及时回填土料,铺设的土工格栅层数视技术要求。
