何为“有纺土工布”（加筋土工布） What is' woven geotextile '(reinforced geotextile)

有纺土工布

Textile geotextile

有纺土工布是由至少两组平行的纱线{或扁线}组成，一组沿织纺的纵{织物行进的方向}称经纱，另一组横向布置称为纬纱。用不同的编制编织设备和工艺将经纱与纬纱交织在一起成布状，可根据不同的使用范围编织成不同的厚度与密实度，一般有纺土工布较薄纵横向都具有相当强的抗拉强度{经度大于纬度}，具有很好的稳定性能。有纺土工布根据编织工艺和使用经纬的不同分为加筋土工布和不加筋土工布两大类，加筋土工布的经向抗拉强度远远大于普通土工布。有纺土工布一般实际应用与土工工程项目的加筋增强，主要功能是加固增强，具有平面隔离与保护功能，不具备平面排水功能可根据具体使用目的选用。

Textile geotextile is composed of at least two sets of parallel yarns or flat threads, one set of which is called warp yarn along the longitudinal direction of the woven fabric, and the other set of which is horizontally arranged is called weft yarn. Using different weaving equipment and techniques to interweave warp and weft yarns into a cloth shape, it can be woven into different thicknesses and densities according to different usage ranges. Generally, woven geotextiles have relatively strong tensile strength in both longitudinal and transverse directions, with longitude greater than latitude, and have good stability performance. Textile geotextiles can be divided into two categories: reinforced geotextiles and unreinforced geotextiles based on the weaving process and the use of warp and weft. The longitudinal tensile strength of reinforced geotextiles is much greater than that of ordinary geotextiles. Textile geotextile is generally used for reinforcement and reinforcement in geotechnical engineering projects. Its main function is reinforcement and reinforcement, with plane isolation and protection functions. If it does not have plane drainage function, it can be selected according to specific usage purposes.
