What is geotextile? Geotextiles are permeable geosynthetic materials made from synthetic fibres by needling or weaving. Geotextiles are one of the new material geosynthetics, finished in cloth form, generally 4-6 metres wide and 50-100 metres long. Geotextiles are divided into spun geotextiles and non-woven filament geotextiles.
Features 1?High strength, due to the use of plastic fibres, it can maintain full strength and elongation in both wet and dry conditions. 2, corrosion resistance, in different degrees of acidity and alkalinity of the soil and water can be corrosion-resistant for a long time. 3?Good permeability There are voids between the fibres, so there is good water permeability. 4?Good anti-microbial property. It is not damaged by microorganisms and insects. 5?Construction is convenient, because the material is light and soft, so it is convenient to transport, laying and construction. 6?Complete specifications: width up to 9m. It is the widest product in China, and the mass per unit area: 100-1000g/m2
Effects 1: Isolation The use of polyester staple geotextiles to separate building materials with different physical properties (particle size, distribution, consistency and density, etc.) (e.g. soil and sand, soil and concrete, etc.). The geotextile keeps two or more materials from losing and mixing with each other, maintains the overall structure and function of the material, and makes it possible for the material to be separated. The overall structure and function of the material is maintained and the load-bearing capacity of the structure is enhanced.
2: Filtration (back filtration) When water flows from the fine material soil layer into the coarse material soil layer, the good air permeability and water permeability of polyester staple geotextile is used to make the water flow through, while effectively intercepting soil particles, fine sand, small stones, etc., in order to maintain the stability of soil and water works.
3: Drainage Polyester staple geotextile has good water conductivity, it can form a drainage channel inside the soil body and drain excess liquid and gas from the soil structure. It can form drainage channels inside the soil structure and drain excess liquid and gas from the soil structure.
4: Reinforcement The use of polyester staple geotextiles enhances the tensile strength and deformation resistance of the soil to improve the stability of the building structure. improve the quality of the soil.
5: Protection When the soil is washed by water, the concentrated stress is effectively diffused, transferred or decomposed, preventing the soil from being damaged by external forces and its protection.
6: Puncture prevention Combined with geomembrane to become a composite waterproof and impermeable material, playing the role of anti-puncture. High tensile strength, good permeability, permeability, high temperature resistance, freezing resistance, ageing resistance, corrosion resistance, no insect infestation. Polyester staple needle-punched geotextile is a widely used geosynthetic material. It is widely used in the reinforcement of railway roadbed, road surface It is widely used in the reinforcement of railway roadbeds, the maintenance of highway pavements, the protection of sports halls and dams, the isolation of hydraulic buildings, caves, coastal beaches, reclamation, environmental protection and other projects.
