土工格栅的意义是什么？

what is the significance of the geogrid?

1.塑料土工格栅

1. plastic geogrid

塑料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。

the plastic geogrid is a polymer mesh with square or rectangular shape formed by stretching. according to its manufacturing direction, the tensile direction can be two kinds: uniaxial tension and biaxial stretching. it is a extruded polymer sheet (the raw material is mostly polypropylene or high density polyethylene) punching, and then subjected to directional stretching under heating conditions. the unidirectional tensile grid is only stretched along the length direction of the sheet, while the biaxially stretched grid continues to stretch the unidirectional stretched grille in the direction perpendicular to its length.

由于塑料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。

due to the rearrangement of polymers in the manufacture of plastic geogrids, polymers will rearrange their orientation along with the heating and extending process, and enhance the bonding force between molecular chains, so as to improve their strength. its elongation is only 10% ~ 15% of the original plate. if the anti aging material such as carbon black is added to the geogrid, it can have good durability, such as acid resistance, alkali resistance, corrosion resistance and aging resistance.

k8凯发-凯发app认为塑料土工格栅在施工时应注意下列问题：支撑在预制混凝土基础上，其宽度不大于30cm，厚度不小于20cm，埋深不小于60cm防止地基冻胀影响；筋材铺设，筋材主强度方向应垂直于墙面，以销钉固定；平整墙基，按设计要求开挖、平整；软土需压实或换填，压实到要求密度，应略超出墙面范围。

plastic geogrid should pay attention to the following questions: in the construction of precast concrete support on the basis, the width is not more than 30cm, the thickness of not less than 20cm, depth of not less than 60cm to prevent the frost heaving of foundation reinforcement effect; laying reinforcement strength, the main direction should be perpendicular to the wall, with the pin fixed flat wall, according to the design requirements; excavation, smooth; soft soil to compaction or replacement, compaction requirements should be slightly beyond the scope of the wall density.

1.2双向土工格栅

1.2 bi-directional geogrid

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。
