Woven geotextiles are polypropylene, C b-fiber ribbonfil as raw material, by at least two sets of parallel yarn (or flat), a group of longitudinal (along the loom fabric direction of travel) called warp, another group of transverse arrangement called weft. With different weave weaving equipment and process of warp and weft intertwined woven into cloth shape, can according to the different scope of use woven into different thickness and density, generally woven geotextile thin vertical has very strong (tensile strength greater than latitude longitude), has a very good stability performance.

　　产品性能：

　　The properties of the product:

　　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。

　　1, reinforcement effect: for road, railway, airport, dam, breakwater, retaining wall backfill and rock engineering such as slope, soil stress increase soil element dispersion modulus, limit soil piece slip, improve stability.

　　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。

　　2, protection: it can prevent banks from the wind, wave, tide, rain erosion, and used for the revetment, slope protection, bottom protection, prevent soil erosion.

　　3、反滤作用：用于堤、坝、河及海岸石快、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。

　　3, filtrate: filtering layer for embankment, dam, river and coastal stone, slope, retaining wall, prevent sand grains through, while allowing free water or air through.

　　安装施工注意事项：

　　Installation and construction matters needing attention:

　　1、土工布只能用土工布刀进行切割(钩刀)，如在场地内切割，对其他材料须采取特殊保护措施，以防由于切割土工布而对其造成不必要的损坏;

　　1, geotextile can only use geotextile knife for cutting (hook), such as cutting in the field, on other materials shall take special protective measures to prevent due to cutting of geotextile and its cause unnecessary damage;

　　2、在铺设土工布的同时，必须采取一切必要措施，以防止对下面一层材料造成破坏;

　　2, the laying of the geotextile and at the same time, we must take all necessary measures to prevent damage to the bottom layer material;

　　3、在铺设土工布时，必须注意不要让石头、大量尘土或水分等有可能破坏土工布、有可能阻塞排水渠或过滤网、或有可能给接下来的连接带来困难的物质进入土工布或土工布的下面;

　　3, in the laying of the geotextile, must pay attention not to let the stone, below a lot of dust or moisture may damage the geotextile, likely blocked drains or filters, or may bring difficulty to the next connection material into the geotextile or geotextile;

　　4、安装结束后，对所有土工布表面进行目测以确定所有损坏的地主，作上标记并进行修补，确定铺设表面没有可以造成损坏的外来物质，如断针等异物;

　　4, after installation of all the geotextile surface was visually to identify all damage to the landlord, mark and repair, identify the laying surface without can cause foreign material damage, such as broken needle and other foreign bodies;

　　5、土工布的连接必须遵循以下规定：正常情况下，坡面上不能有水平连接(连接须沿坡面的轮廓不与其相交)，除修补的地方以外。

　　5, geotextile connection must comply with the following provisions: under normal circumstances, the slope surface can not have horizontal connection (connection must be along the slope contour rather than intersecting), except for the repairs.

　　6、如采用缝合，缝合线须采用与土工布材质相同或超过的材料，缝合线须为防化学紫外线的材持。缝合线与土工布应有明显的色差，以便于检查。

　　6, such as the use of suture, suture line will be adopted and geotextile materials are the same or more than material, suture line must be chemical resistant ultraviolet to. Suture and geotextile has obvious color difference, in order to check.

　　7、安装时对缝合特别注意以确保没有泥土或砾石覆盖层中的砾石进入土工布中间。

　　7, installation of suture pay special attention to ensure that no dirt or gravel in the cover layer of gravel into the geotextile intermediate.
