The application of Short fiber needle punched geotextile:
As the geotextile with acupuncture has for more than six major functions, it is widely used in:
- Railways, highways,
- Sport stadiums, dams, construction of hydraulic
- Tunnel, coastal beaches, reclamation and environmental protection projects.
The Characteristics of Short fiber needle punched geotextile:
- The use of geotextile different physical properties (particle size, distribution, density and thickness, etc.) materials (such as soil and sand, sand and gravel soil, soil and concrete, etc.) for isolation. So that tow or more material are not loss of inter-and non-hybrid, to maintain the overall structure of the material and functions of the structures is to strengthen the load bearing capacity.
- The good air and water permeability can make the water flow through, and effective interception soil particle, pinning, the small stone so as to maintain the stability of the soil and water projects.
- It is a good hydraulic material, which can form a soil internal drainage channel, soil structure and excess liquid gas emissions.
- Acupuncture use of geotextile to enhance soil and the tensile strength of the anti-deformation ability to increase the stability of the building structure in order to improve the quality of the soil.
- It can focus on the effective stress –proliferation, transfer or broken down by external force to prevent the soil and damage.
- Acupuncture geotextile and other materials (primarily asphalt or plastic film) with the formation of impermeable layer of insulation layer.
