A Piece Of Cloth Can Build A Bridge And Repair Roads. Is This Your Textile?

In 1926, the relevant department of South Carolina first applied cotton fabric to highway construction, which is the rudiment of modern geotextiles. Later, with the development of science and technology and application, the processing technology of geotextiles has become more and more professional, and has been widely applied in many engineering fields all over the world, including highways, railways, airports, ports, water conservancy, wind power, environmental protection, municipal administration and so on.

Road reinforcement

The amount of geotextiles used in road reinforcement is very large, mainly including road construction on Soft Soil Foundation (including highways and railway construction). On temporary roads or construction platforms, because of its too soft foundation soil, it can not support the initial construction work. The use of geotextile reinforcement can reduce the thickness of crushed stones needed for construction equipment to enter the site and maintain the stability of the roadbed. Besides, the use of Geotextiles for road construction can reduce the thickness of the roadbed and avoid long-term maintenance problems.

　　 In road construction, Geotextiles have synergy with other functions besides reinforcement, such as separating the gravel from the roadbed, and deriving the water from the soft foundation to the drainage function of the aggregate layer.

Marine Engineering

The role of Geotextiles in marine engineering is mainly to protect land and man-made structures from seawater impact and to maintain their structural stability. There are two main application forms at present: one is the material used alone for filtering or improving structural stability; the other is used as filling outer shell, internal sand filling, etc. as material for erosion resistance and structural stability.

　　 Woven geotextiles are often used in marine engineering such as geotextiles, Geotextiles and geotextiles. Polypropylene woven geotextiles are often used in offshore engineering. They have good filtration effect on sand and can maintain the stability of shape and structure. Composite geotextiles have excellent wear resistance, impact resistance and UV resistance, so they are very suitable for exposure to marine environment for a long time.

Soil erosion protection

Geotextiles can absorb and store large amounts of water to slow down their erosion and damage to the soil surface, so that soil erosion can be realized. In the application of erosion control, geotextiles are mainly in the form of geotechnical erosion control network, open erosion control blanket, woven geotextile or geosynthetic liner. Natural fiber geotextiles are mainly used for slope erosion protection around the slowly flowing small watercourses. They can be degraded with time, providing certain fertility for the soil and promoting vegetation growth.

Environmental protection and seepage prevention

In the field of anti-seepage engineering, geotextile textiles are mainly used in sewage treatment, landfill, tailings treatment, and coal ash plant. In these areas, wastes will produce gas and leachate and other harmful substances after long time stacking, which will cause pollution to soil and groundwater. Therefore, impervious composite geomembrane is mostly used to prevent such phenomena. The composite geomembrane is composed of Geotextiles and geomembrane. It can be divided into two structures: one cloth and one membrane, and two cloth and one membrane. Besides good anti-seepage effect, the products should also have excellent physical properties such as tensile, tear resistance and anti bursting.
