PET filament geotextile fabric is a kind of high strength, high modulus and durable geosynthetic material, its main role is used for geotechnical isolation, geotechnical strengthening and geotechnical protection. In tailings treatment, filament geotextile fabrics are usually used for the seepage prevention function of tailings DAMS.
Features
The selection of filament geotextile fabrics as impermeable materials for tailings DAMS is mainly because of its good durability, which can withstand long-term underwater immersion and oxidative corrosion, and its high strength and high modulus can also effectively resist the osmotic pressure and erosion damage of tailings. In addition, the filament geotextile fabric also has good filtration and drainage performance, which can help the tailings dam to quickly remove water, thereby reducing the risk of leakage.
Case Study Of PET Filament Geotextile Fabric for Tailings Project
The South African government project contractor contacted the salesman through the BPM website, they won the bid for the tailings project, they need us to provide the technical indicators of non-woven geotextiles, samples, and third-party testing reports, focusing on alkaline resistance, BPM salesman recommended the filament geotextile fabrics, 500g/m2 according to the requirements of the customer’s project. After receiving the samples, the customer asked a third-party testing company to test various indicators, and finally they were very satisfied with our products and fully met the requirements of the customer. Therefore, after communication on quantity, price, delivery time and payment method, we finally reached a cooperation.
Why Choose PET Filament Geotextile Fabric for Tailings Project?
Good durability:
Filament geotextile fabric has good durability, can withstand long-term underwater immersion and oxidation corrosion, can be used in harsh environments for a long time, suitable for tailings treatment.
Excellent permeability resistance:
Filament geotextile fabric has good permeability resistance and can effectively resist the osmotic pressure and erosion damage of tailings, thereby reducing the risk of leakage.
High tensile strength:
Filament geotextile fabric has high tensile strength and can withstand larger loads, which is suitable for strengthening and protecting tailings DAMS.
Convenient construction:
The filament geotextile fabric can be customized according to the specific design and use requirements of the tailings dam, convenient construction, quick installation, and improve work efficiency.
The product is mainly used in the following characteristics:
- It can play a permanent isolation role; The soil layer composed of different components and properties can be isolated for a long time and prevent mixing; With frost resistance and load requirements required for construction.
- With good filtration performance and anti-corrosion performance; Water can penetrate in all directions without building up pressure. At the same time, it can prevent soil loss, which is conducive to stability and corrosion resistance.
- With reliable drainage performance; Due to the fluffiness of its structure, it can effectively control the drainage of geotechnical engineering surface.
- With good protection performance; Due to its good puncture, extensibility and fluffiness, it can effectively protect the waterproof layer from potential mechanical damage.
- With reinforcement performance; The fluffiness and high strength improve the overall stability of the project and increase its strength.
Function of filament geotextile fabric
Isolation
That is, geotextiles are used to isolate building materials with different physical properties (particle size, distribution, consistency and density, etc.) (such as soil and sand, sand and gravel, soil and concrete, etc.). So that two or more materials do not lose, do not mix, maintain the overall structure and function of the material, so that the structure load bearing capacity is strengthened.
Filtration
When the water flows from the fine-grained soil layer into the coarse-grained soil layer, the good permeability and water permeability of the needled geotextile are used to make the water flow through. And effectively intercepted the soil particles, fine sand, small stone, etc., in order to maintain the stability of soil and water engineering.
Drainage
Geotextile is a good water conductive material, which can form a drainage channel in the soil structure and remove excess liquid and gas from the soil structure.
Reinforcement
The use of geotextile to enhance the tensile strength and deformation resistance of soil, enhance the stability of building structure, and improve the quality of soil.
Protection
The concentrated stress can be diffused, transferred or decomposed effectively to prevent the soil from being destroyed by external forces.
Closure
Geotextile works with other materials (asphalt, plastic film) to form an impervious barrier in the soil layer. (Mainly used for highway resurfacing, repair, etc.).
Construction and laying of filament geotextile fabric
-
Storage, transportation and treatment of geotextiles
Geotextile rolls should be protected from damage before installation and development. Geotextile rolls should be stacked in a place that is flat and does not accumulate water, and the height of the pile should not exceed four rolls, and the identification piece of the roll can be seen.
-
Geotextile laying method
Manual rolling; Cloth surface should be smooth, and leave a deformation margin. The installation of the filament is usually by several methods, such as bonding, stitching and welding.
-
Stitching of geotextile
All stitching must be done continuously (for example, spot stitching is not allowed). The geotextile must overlap at least 150mm before overlapping. The minimum stitch distance from the woven edge (the exposed edge of the material) is at least 25mm.
Appropriate measures must be taken to prevent soil, particulate matter or foreign substances from entering the geotextile layer after installation. The lapping of cloth can be divided into natural lapping, sewing or welding according to the terrain and the function of use.
