Polypropylene woven geotextile

 塑料扁丝编织土工布以聚丙烯（PP）、聚乙烯（PE）为主要原料，经过挤出、切膜、拉伸制成扁丝（单丝、裂膜丝）后编织而成。塑料扁丝编织土工布强力高，在干湿状态下都能保持充分的强力和伸长率；在不同的酸碱度的泥土及水中能长久地耐腐蚀；扁丝间有空隙，故而有良好的渗水性能；抗微生物、虫蛀均不受损害；材料轻、柔，故而运送、铺设、施工方便。

 Woven geotextile mainly uses polypropylene（PP),polyethylene(PE) as raw materials. After extruding, film slitting, stretching, flat yarn(single yarn, film splitting yarn) is knitted into geotextile.Woven geotextile has high strength and can keep enough strength and elongation in dry and wet condition. It has long term corrosion resistance in the soil and water with different PH; There are gaps between flat yarns, making it has excellent water permeability performance. Due to its excellent microbiological degradation resistance, the geotextile will be free from damaged by micro-organism and worm. The material is light and soft, so it is convenient to transport and install.

1.加筋作用：用于公路、铁路、机场、石坝、防坡堤、挡土墙回填土、边陂等岩石工程，分散土体应力增加土件模量、限制土件滑移，提高稳定性。

　　

2.防护作用：防止堤岸受风、浪、潮、雨的冲刷，并用于护岸、护坡、护底、防止水土流失等工程。

 　　

3.反滤作用：用于堤、坝、河及海岸石块、土坡、挡土墙的滤层，防止砂土粒通过，而允许水或空气自由通过。

Application Range

1.Reinforcement: Used in the constructions of highway, railway, airport, dam, prevent slope dike, retaining wall, etc. to improve stability.

2.Protection: To prevent the bank from eroding by wind, wave ,tidal and rain. Used for the projects such as revetment, slope protection and bottom protection, anti-soil erosion,etc.

3.Filtration: Used as filtering layer of dike, the dam, river and coast stone , slope, retaining wall to prevent sand grain through and allow freedom through of air or water.
