参数

产物先容:

双向拉伸塑料土工格栅的表面是类似正方形的网格状布局，它因此聚丙烯及高密度聚乙烯为头要原資料，途经步骤热融挤出成板，冲孔，升温，纵览向产品定位拉长而成。

产物特色:

1.弯曲标准高，立体图像抗扭模量高，耐脆性断裂器能好，生物学脾性不减。 2、较高的抗机气破碎才可和经久才可，与砂砾的滚动摩擦常数大。 3、能努力基础桩的有着力(常见能努力40%以下) ,改变不集中角(一致从38度增长到50度)。

4、在划一荷载的轴次感化下，到达一样的结果。可削减30%- 40%的填土速率，接纳土工格栅加筋时，一种层厚的填方路基可多承载过重，这个是需要注意的，液晶屏要控制在适合的数量内3 -5倍多。

5、在物料中增强无卤剂和防静电包装感应剂，生厂煤厂矿井用双边拉伸弹簧pp塑料网假顶。

利用规模:

1.多种高速公路、铁路线、高铁站的路面工程切实加强。 2、大规模停车场和船埠货场等无论如何性承受力的柱基进一步提高。 3.铁路桥、一级公路的公路边坡防防、涵洞增强。 4、单方面收缩土工网格板加大后的土坡的两次加大，进一次加大土坡，以免水土散失。 5、矿井、坑道加固工程。

Bi-direction geotechnical grid of plastic

Product Introduction

Appearance of bidirectional tension plastic geotechnical gird is grid shape structure with near square.It uses polypropylene and high-density polyethylene as main raw materials,is pressd into plate by melting extrusion and tormed by punching.heating.vertical and horizontal directinal ten-sion.

Product feature

1.High tension resistance,high plane torsion resistance modulus. good creepresistance and stable chemical nature.

2.High mechanic damage resistance and durability and large tiction factor with sandy stone.

3.It can improve bearing force of foundation(normal improvement of above 40%)and increase dif-fusion angle(average increase to 50 degree from 38 degree).

4.Under the function of shaft timnes with same load,it can decrease 30%- 40% of fling thickness for reaching same effect,when geotechnical grid reinforcement is used,road bed with same thickness can bear more 3-5 times.

Application range

1.Reinforcement of road beds of various highways and airports. 2.Reintforcement of permanent bearing road beds of large parking areas and dock goods yard. 3.Slope protection and culvert reinforcement of railway and highway.

4.Secondary reinforcement of soil slope atter unidirectional tension geotechnical grid reinforce-ment and further reinforcement of soil slope so as to avoid soil erosion.

5.Reinforcement of mile and gallery.
