The main uses of airport isolation geotextile are as follows:
Isolation: Isolate building materials (such as soil and sand, soil and concrete) with different physical properties (such as particle size, distribution, consistency, and density) to prevent loss or mixing between two or more materials, maintain the overall structure and function of the materials, and enhance the load-bearing capacity of the structure.
Filtration (reverse filtration): When water flows from the fine soil layer into the coarse soil layer, its good breathability and permeability are utilized to allow water to pass through, effectively intercepting soil particles, fine sand, small stones, etc., and maintaining the stability of soil and water engineering.
Drainage: It has good water conductivity and forms drainage channels inside the soil to discharge excess liquids and gases from the soil structure.
Reinforcement: Enhance the tensile strength of soil.
The key points for the construction of airport isolation geotextile are as follows:
Preparation before construction: Ensure that the construction site is level, remove debris and sharp objects.
Laying direction: The laying direction should be determined according to the needs of the project and generally kept straight.
Laying method: Due to the light and flexible material, it should be carefully transported and laid to avoid damage caused by strong pulling.
Overlap treatment: There should be sufficient overlap width between adjacent geotextiles, usually not less than 10 centimeters, and proper connection treatment should be carried out.
Fixed measures: Take fixed measures at necessary locations to prevent the geotextile from shifting during construction.
