各种各样的土工格栅介绍

塑料土工格栅 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。

Stretch plastic geogrid is formed by polymer with square or rectangular mesh material, when they are made according to the drawing direction for uniaxial tensile and two-way stretch two kinds. It is in the extrusion make polymer material (raw material for polypropylene and high density polyethylene) on punch, then execute directional stretch under heating conditions. Single to stretching grating sheet along the length direction only stretching, one-way and two-way stretch grille is continue stretching grille again in its vertical direction tensile 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。

Because the plastic geogrid in the manufacturing of polymer macromolecule and rearrange the directional extend along with the heating process, strengthen the binding force between the molecular chain, achieved the purpose of improve its intensity. The elongation rate is only 10% ~ 15% of the original sheet. If add anti-aging material such as carbon black, in geogrid can make its have good acid and alkali resistance, corrosion resistance and anti-aging endurance performance. 钢塑土工格栅 Steel-plastic geogrid

钢塑格栅由高强度钢丝通过高密度聚乙烯包裹成高强度条带，按平面经纬成直角，经超声波焊接成型的土工合成材料，根据工程需要来用不同网孔直径及钢丝根数来改变筋带的拉力大小。

Steel-plastic geogrid made from high strength steel wire by high-density polyethylene package into high strength strip, according to the plane at right angles, after ultrasonic welding forming of geosynthetic materials, according to the project need to use different number of mesh and wire diameter to change the tension size ribbon.

钢塑格栅有什么特性 1、钢塑格栅的拉力由经纬编织的高强钢丝承担，在低应变能力下产生极高的抗拉模量，纵横向肋条协同作用，充分发挥格栅对土体的嵌锁作用。

What features 1, gangsu gangsu gratings pulling force borne by

warp/weft weaving high strength steel wire, in low strain capacity under high tensile modulus, lateral rib synergy, give full play to the grille on the soil of interlocking function.

2、钢塑格栅的纵横向肋条的钢丝经纬编织成网，外包裹层一次成型，钢丝与外包裹层能协调作用，破坏伸长率很低（不大于3%）。钢塑复合土工格栅的主要受力单元为钢丝，蠕变量极低。

2 steel-plastic grid of vertical and horizontal to the rib steel wire knitting, woven mesh, outside the parcel layer of a molding, wire and outside the package layer can coordination effect, low break elongation (not more than 3%). - the shoes should be insulators, the person is in touch electric wire without cont

3、通过生产过程中塑料表面的处理，压制有粗糙的花纹，以增强格栅表面的粗糙程度，提高钢塑复合土工格栅与土体的摩擦系数。

3, through the production process on the surface of the plastic processing, suppression with rough pattern, in order to enhance the roughness on the surface of the grating, improved steel-plastic composite geogrid and soil friction coefficient.

4、钢塑格栅的幅宽可达6m，实现高效、经济的加筋效果。 4, gangsu grille width can be up to 6 m, efficient and economical reinforcement effect.

5、钢塑格栅采用的高密度聚乙烯可以确保：在常温下不会受

到酸碱及盐溶液，或油类的侵蚀；不会受到水溶解或微生物的侵害。同时，聚乙烯的高分子性能也足以抵抗紫外线辐射所造成的老化。格栅受力后纵横肋条协同作用，不会产生结点的拉裂或破损。而实际工程中，在填料的压实后，因此未受到紫外线光和氧的侵蚀，因此完全可以满足永久性工程建设的要求。

5 steel-plastic grid using high density polyethylene can ensure that: at room temperature are not subject to acid and alkali and salt solution, or the erosion of oil; Was not influenced by water dissolution or microbes. At the same time, the polyethylene polymer performance is sufficient to resist ultraviolet radiation caused by aging. Grating stress after the vertical and horizontal rib synergy, won't produce nodes of cracking or breakage. In practical engineering, the packing material after compaction, erosion, therefore not subjected to ultraviolet light and oxygen so can completely meet the requirements of permanent project construction. 6强度大、蠕变小、适应各类环境土壤，完全可以满足高等级公路中的高大挡墙使用。
