Geotextile geomembrane for dam lakes is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Geotextile is one of the new geosynthetic materials. The finished product is in the shape of cloth, generally with a width of meters and a length of meters. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles.
Features: High strength. Due to the use of plastic fibers, it can maintain sufficient strength and elongation in wet and dry conditions.
, Corrosion-resistant, can resist corrosion for a long time in soil and water with different pH levels.
, good water permeability. There are gaps between fibers, so it has good water permeability.
It has good anti-microbial properties and is not damaged by microorganisms and insects.
, Convenient construction. Because the material is light and soft, it is convenient to transport, lay and construct.
, complete specifications and width up to meters. It is currently the widest product in China, with mass per unit area: /㎡
Function
: Isolation
Polyester staple fiber needle-punched geotextiles are used to have different physical properties (particle size, distribution, consistency and Density, etc.) building materials (soil and sand, soil and concrete, etc.) are isolated. It prevents the loss or mixing of two or more materials, maintains the overall structure and function of the materials, and enhances the load-bearing capacity of the structure.
: Filtration and reverse filtration)
When water flows from the fine soil layer into the coarse soil layer, the good air permeability and water permeability of the polyester staple fiber needle-punched geotextile are used to allow the water flow
to pass , and effectively intercept soil particles, fine sand, small stones, etc. to maintain the stability of water and soil engineering.
: Drainage
Polyester staple fiber needle-punched geotextile has good water conductivity. It can form drainage channels inside the soil to drain excess liquid and gas out of the soil structure.
: Reinforcement
Use polyester staple fiber needle-punched geotextile to enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure, and improve the quality of the soil.
: Protection
When water flows against the soil, it effectively diffuses, transfers or decomposes the concentrated stress, preventing the soil from being damaged by external forces and protecting the soil.
