Introduction Of Geotextile
Dec 20, 2017

Geotextile is a geosynthetic material which is widely used in geotechnical engineering today. It is a general name for high molecular polymer products. As early as 1920s, the chemical sector successfully produced synthetic materials, but until the late 50s, this material was gradually applied as a new building material in geotechnical engineering. The early products were mainly permeable spinning and nonwoven geotextiles, and later produced water permeable geomembrane. With the requirements of the engineering practice and the improvement of the manufacturing process, the geogrid and other combined products of high strength reinforcement have been produced. In this way, the word "geotextile" has been far from being able to summarize the meaning of all kinds of products. Therefore, many alternative names have appeared in the world. The word "geotextile" is most commonly used, but it is still commonly referred to as geotextile. [1] geomembrane can be divided into several main categories: geotextile, geomembrane, geogrid, drainage plate, composite geomembrane, geotextile, geocell, bentonite waterproof blanket, etc.

Glass fiber geogrid is a new type of excellent geomembrane for reinforcing roadbed and roadbed. The product is made of alkali free glass fiber filament as main raw material and woven by special warp knitted weaving technology and coated with special rubber. It can effectively improve the stress distribution of the road structure, resist and delay the occurrence of reflective cracks caused by the cracks at the grassroots level, improve the service life of the road, and reduce the cost and improve the quality of the construction. The product is a new type of patent products the company launched, using glass fiber geogrid self adhesive coating treatment, while keeping the glass fiber geogrid characteristics and function, the grid and the contact surface layer closely together, has the advantages of convenient construction, etc. the whole pool paving, especially suitable for highway pavement construction, reinforcement and transformation of the old road engineering reinforcement. Composite geotextile is a new composite geotextile material with high strength polyester fiber or glass fiber yarn and woven fabric by weaving or bonding, combines the excellent performance of glass fiber and non-woven fabric of the two, in addition to have high strength geogrid with high elastic modulus, low elongation. Resistance, temperature and other characteristics, also has the anti permeability and anti filter ability is good, geosynthetics is a kind of multifunctional, can effectively prolong the service life of project and reduce maintenance frequency, reduce project cost, suitable for road pavement and roadbed, dam water conservancy engineering reinforcement and isolation and protection. High strength polyester fiber geogrid is a new high quality geomembrane for reinforcing roadbed. It uses high strength polyester fiber or polypropylene fiber as raw material, warp knitted directional weaving and special process dip coating. The extension has high tensile strength, low rate, can effectively prevent the pavement cracking in roadbed engineering, improve the bearing capacity of soft soil foundation, prevent foundation settlement, reduce project cost, improve the efficiency of construction, so as to improve the service quality and service life of highway and railway engineering.
