1: Separation
Poking soil with polyester staple fiber is to isolate building materials with different physical properties (particle size, distribution, density, density, etc.) (such as soil and sand, soil, concrete, etc.). There is no loss or mixing between more than two materials, the overall structure and function of the materials are maintained, and the bearing capacity of the building is strengthened.
2: Filtering (filtering)
When water flows from the fine soil layer to the coarse soil layer, the polyester staple fiber is used to pierce the air permeability and water permeability of the geotextile to form water flow
In this way, soil particles, fine sand and small stones can be effectively intercepted to maintain the stability of water and soil engineering.
3: Drainage
Polyester staple fiber needle punched geotextile has good hydraulic conductivity, which can form drainage channels in the soil and mostly enter the soil structure.
The remaining liquid and gas are discharged from the body.
4: Reinforcement
The geotextile is punctured with polyester staple fiber to enhance the tensile strength and deformation resistance of soil, improve the stability of building structure and repair.
Good soil quality.
5: Protect
When the water is washed by the soil, it can effectively diffuse, transfer or decompose the concentrated stress to prevent the soil from being damaged by external forces, so as to protect the soil.
6: Prevent puncture
Combined with geomembrane, it becomes a composite waterproof and impermeable material, which can prevent puncture.
Fabric application field (1) It is used as reinforcement in the backfilling of retaining wall or for anchoring the panel of retaining wall Construction of wrapped retaining wall or abutment Application of Geotextile in construction (2) Reinforce the flexible pavement, repair the cracks on the road and prevent the pavement from reflecting cracks (3) Increase the stability of gravel slope and reinforced soil, and prevent water and soil loss and freezing damage of soil at low temperature (4) The isolation layer between ballast and subgrade, or between subgrade and soft foundation (5) Isolation layer between artificial fill, rockfill or material yard and foundation, and isolation between different frozen soil layers Inverted filtration and reinforcement.
