Geotextiles

Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers by needling or knitting. Geotextile is one of the new geosynthetics. The finished product is cloth like, with a width of 2-6m and a length of 50-100m.

Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers by needling or knitting. Geotextile is one of the new geosynthetics. The finished product is cloth like, with a width of 2-6m and a length of 50-100m. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles.

Characteristic

1. High strength. Due to the use of plastic fiber, it can maintain full strength and elongation under dry and wet conditions.

2. Corrosion resistance, in different pH of soil and water can be long-term corrosion resistance.

3. The water permeability is good because there is a gap between the fibers, so it has good water permeability.

4. Good anti microbial property will not damage microorganism and moth.

5. The construction is convenient. Because the material is light and soft, it is convenient to transport, lay and construct.

Effect

1: isolation

Construction materials with different physical properties (particle size, distribution, consistency, density, etc.) are treated with polyester staple fiber needle punched Geotextile

Materials (such as soil and sand, soil and concrete, etc.) shall be isolated. Keep two or more kinds of materials together

The overall structure and function of the material strengthen the carrying capacity of the structure.

2: Filtration (reverse filtration)

When the water flows from the fine soil layer to the coarse soil layer, the polyester staple fiber needled geotextile has good permeability and water permeability to make the water flow

Through, and effectively intercept soil particles, fine sand, small stone, etc., in order to maintain the stability of water and soil engineering.

3: drainage

Terylene staple fiber needle punched geotextile has good water conducting performance, it can form drainage channel in the soil body, which will make the soil structure more

The remaining liquid and gas are discharged.

4: reinforcement

In order to improve the stability of the building structure, the tensile strength and deformation resistance of the soil are enhanced by using polyester staple fiber needle punched geotextile

Good soil quality.

5: protection

When the water flow scours the soil, it can effectively diffuse, transfer or decompose the concentrated stress, prevent the soil from being damaged by the external force, and protect the soil.

6: puncture prevention

Combined with the geomembrane, the composite waterproof and anti-seepage material plays the role of anti puncture.

High tensile strength, good permeability, air permeability, high temperature resistance, freezing resistance, aging resistance, corrosion resistance, non moth.

Polyester staple fiber needle punched geotextile is a widely used geosynthetic material. Widely used in the reinforcement of railway subgrade and highway pavement

Maintenance, sports hall, dam protection, hydraulic construction isolation, Suidong, coastal beach, reclamation, environmental protection and other projects.

Characteristic:

Light weight, low cost, corrosion resistance, excellent performance of filter, drainage, isolation and reinforcement.

Purpose:

It is widely used in water conservancy, electric power, mine, highway, railway and other geotechnical engineering:

l. Filter material of soil layer separation;

2. Drainage materials for mineral processing of reservoirs and mines, and drainage materials for foundation of high-rise buildings;

3. Anti scour materials for river dikes and revetments;

4. Reinforcing materials for railway, highway and airport runway subgrade, and for road construction in swampy areas;

5. Anti frost and anti freezing insulation materials;

6. Anti crack material of asphalt pavement.
