geotextile
1：隔离,利用涤纶短纤针刺土工布对具有不同物理性质（粒径大小、分布、稠度及密度等）的建筑材料（如土体与沙粒、土体与混凝土等）进行隔离。使两种或多种材料间不
流失，不混杂，保持材料的整体结构和功能，使构筑物载承能力加强。
2：过滤,当水由细料土层流入粗料土层时，利用涤纶短纤针刺土工布良好的透气性和透水性，使水流通过，而有效地载流土颗粒，细沙、小石料等，以保持水土工程的稳定。
3：排水,涤纶短纤针刺土工布具有良好的导水性能，它可以土体内部形成排水通道，将土体结构内多余液体和气体外排。
4：加筋,利用涤纶短纤针刺土工布增强土体的抗拉强度和抗变形能力，增强建筑结构的稳定性，以改善土体质量。
5：防护,水流对土体冲刷时，有效的将集中应力扩散，传递或分解，防止土体受外力作用而破坏，其保护土壤。
6：抗拉强度高、渗透性好、透气性能、耐高温、抗冷冻、耐老化、耐腐蚀、不虫蛀。

Advantages of geotextile:
1. Isolation. Construction materials (such as soil and sand, soil and concrete, etc.) with different physical properties (particle size, distribution, consistency and density, etc.) are isolated by using polyester staple fiber needled geotextile. Make two or a variety of materials between no loss, not mixed, maintain the overall structure and function of the material, so that the structure carrying capacity is strengthened.
2: Filtration, when the water flows from the fine soil layer into the coarse soil layer, the polyester staple fiber needled geotextile has good air permeability and water permeability to make the water flow through, and effectively carry the soil particles, fine sand, small stone, etc., in order to maintain the stability of soil and water engineering.
3: Drainage, polyester staple fiber needled geotextile has good water conductivity, it can form a drainage channel inside the soil, the soil structure of the excess liquid and gas out.
4: Reinforcement, using polyester staple fiber needled geotextile to enhance the tensile strength and deformation resistance of soil mass, enhance the stability of building structure, to improve the quality of soil mass.
5: protection, water erosion of the soil, the effective diffusion of concentrated stress, transfer or decomposition, to prevent the soil by external force and damage, the protection of the soil.
6: High tensile strength, good permeability, breathable performance, high temperature resistance, freezing resistance, aging resistance, corrosion resistance, no moth.Polyester filament non - woven geotextile has excellent heat and light - resistant properties. Even in the environment of nearly 20℃ short-term exposure, its performance is almost unchanged. It has been proved by a lot of experiments and practice that polyester filament non-woven geotextile has long-term corrosion resistance to various natural soil, water and microorganisms. The product is mainly used for the following characteristics:
1, can play a permanent isolation role;
The soil layer composed of different components and properties can be isolated for a long time and prevent mixing;
It has frost resistance and bearing capacity required by construction.
2, with good filtration performance and anti-corrosion performance;
Water can penetrate in all directions without building up pressure. At the same time, it can prevent soil loss, which is beneficial to stability and anticorrosion performance.
3, with reliable drainage performance;
Because of its fluffy structure, it can effectively control the drainage of civil rock engineering surface.
4, with good protection performance;
Due to its good puncture, extensibility and fluffiness, it can effectively protect the waterproof layer from potential mechanical damage.
5, with reinforcement performance;
The fluffiness and high strength improve the overall stability of the project and increase its strength.Keywords:- geotextile
