Application Field Of Geotextiles

Application in road construction field

The amount of geotextiles in road construction is very large, accounting for about half of the total consumption of geotextiles, which mainly relies on the interface friction between geotextiles and surrounding soil to limit the lateral movement of soil, increase the bearing capacity of soil, so as to improve the integrity and structural support capacity of soil and buildings during use. In addition to the high mechanical strength of the high-performance geotextile itself, its surface should also have a high roughness, so as to achieve the reinforcement of the soil or gravel on its surface through the transverse binding force.

In the process of road construction, high-performance geotextiles have other functions in addition to playing a strengthening role: for example, the separation function of separating gravel from the roadbed, and the drainage function of draining water from the weak foundation to the aggregate layer. In addition, on the temporary road or construction platform, the use of geotextile reinforcement can effectively improve the problems faced by the construction of too soft soil, so as to reduce the thickness of the gravel required for construction equipment to enter the site and maintain the stability of the roadbed.

Applications in the field of ocean engineering

High-performance geotextiles in the application process can also play a role in protecting land, man-made structures and man-made structures in seawater from seawater impact and maintain its structural stability, so it is also widely used in port engineering, coastal engineering and offshore engineering. In addition, the healthy development of the island ecosystem is also an important part of the ecological security of various countries, so high-performance geotextiles will continue to be widely used in the bay and coast protection, construction of seawalls, reclamation of the sea and other projects. Moreover, in the process of application in the field of Marine engineering, the hydraulic mechanical properties and durability of geotextiles become crucial.

Application in the field of environmental protection and seepage prevention

At present, for landfill, sewage treatment, tailings treatment, coal ash pile plant and other projects, it is necessary to use a large number of high-performance composite geotextiles to provide seepage prevention and protection. In addition, a large amount of investment in environmental protection projects such as landscape greening, ecological garden construction, "sponge city" construction, and ecological slope protection has further promoted the development and application of high-performance geotextiles.
