Knowledge introduction and popularization of geotextile

Jun 28, 2021

Geotextile, also known as geotextile, is a geosynthetic material made of fibers through needle punching or weaving into a cloth shape. It is a kind of non-woven and industrial non-woven fabric products, a new type of geotechnical material used in civil engineering prescribed by the state. Geotextile has good air permeability and water permeability, allowing water to pass through to effectively intercept sand and soil loss; Geotextile has good water conductivity, it can form a drainage channel inside the soil, and make the soil structure more than liquid; And gas discharge; geotextile has the ability to enhance the tensile strength and deformation resistance of the soil, and enhance the stability of the building structure. The quality of the soil effectively spreads, transfers or decomposes the concentrated stress, prevents the soil from being damaged by external forces, and prevents the upper and lower layers of sand and gravel, soil and concrete from mixing;

Features of geotextile:

The mesh is not easy to be blocked-the mesh structure formed by the indeterminate fibrous tissue has strain and mobility;

High water permeability-it can still maintain good water permeability under the pressure of soil and water;

Corrosion resistance-using polypropylene or polyester and other chemical fibers as raw materials, acid and alkali resistance, corrosion resistance, no insects, and oxidation resistance;

Simple construction-the product is light in weight, easy to use, and simple in construction;

Geotextile has excellent filtering, isolation, reinforcement and protection, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, and corrosion resistance;

The main application fields of geotextile: water conservancy engineering: seawall, river embankment, lake embankment compliance engineering; reservoir reinforcement engineering; reclamation engineering; flood prevention and rescue; highway and railway airport engineering: soft foundation reinforcement treatment, side slope protection, pavement anti-reflective crack structure Layer, drainage system, green isolation zone; electrical engineering: nuclear power plant foundation engineering, thermal power ash dam engineering; hydropower station engineering.
