双向拉伸土工格栅生产线及技术 双向拉伸土工格栅是高分子聚合物通过挤出、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的力的承担和扩散的理想的连锁系统，适应于大面积性承载的地基补强。 格栅产品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。 Biaxial plastic geogrid production line and technology The biaxial geogrid is made of macromolecule polymer through extruding, sheet forming, holes punching longitudinal and transversal stretching. This kind of material exhibits great tensile strength at both longitudinal and transversal directions, such structure can also provide an ideal chain system for bearing and spreading the force in the soil, which is suitable for permanent reinforcement of large-area foundation. The geogrid product is suitable for reinforcement of embankment, subgrade, slope and tunnel wall, and reinforcement of permanent foundation, such as large airport, parking lot, dock, and so on. 1. Increase the bearing capacity of the road (ground), and prolong the service life of the road (ground). 2. Protect the road (ground) surface from subsiding or cracking, and keep the road (ground) beautiful and neat. 3. It is convenient for construction, which can save time and labour force, and reduce the maintenance cost. 4. Protect the culvert from cracking. 5. Enhance the slope, and prevent soil erosion. 6. Reduce cushion thickness, and save cost. 7. Keep the stability of the slope of grass mat for green environment. 8. Replace metal net to be used as the top net in the coal mine.
