单向拉伸土工格栅生产线及技术
单向拉伸土工格栅是由高分子聚合物经挤压成薄板再冲规则孔网，然后纵向拉伸而成。这种过程使高分子成定向线性状态，形成分布均匀、节点强度高的长椭圆形网状整体性结构。此种结构具有相当高的拉伸强度和拉伸模量，给土壤提供了理想的力的承担和扩散的连锁系统，是目前广为采用的加筋加固材料。
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。
Uniaxial plastic geogrid production line and technology
The uniaxial geogrid is formed by extruding the macromolecule polymer into sheet, and punching the sheet into regular net, then stretching the net longitudinally. This process makes the polymer into a state of linear orientation, and forms long oval-shape integral net structure with uniformly distributed nodes of high strength. Such structure possesses very high tensile strength and tensile modulus, and provides an ideal chain system for bearing and spreading the force in the soil. It is a kind of reinforcement material widely used currently.
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.
