Instruction of PP Woven Geotextile for Dam Construction:
Geotextiles are composed from synthetic polypropylene/polyester fibres through a mechanical process of needling the fabric and adding, when necessary, a thermo fused process, resulting in a uniform porous structure with excellent tensile strength and chemical deterioration. Type: 1. Wovens & knitted: use various fibre types (e.g. monofilament, multi-filament, split extruded film) in different combinations. 2. Non-wovens: staple or continuous fibres that are heat treated or needlepunched to “fix” fibres relative to each other.

- Q: How do geotextiles help with reinforcement of geogrid retaining walls?
- Geotextiles help with the reinforcement of geogrid retaining walls by acting as a separator between the backfill materials and the geogrids. They prevent the fine particles in the backfill from clogging the geogrids, maintaining their effective functioning. Additionally, geotextiles distribute the load evenly across the geogrids, enhancing their strength and stability.
- Q: 300g / m2 geotextile permeability coefficient is generally how much?
- Geotextile cloth short fiber geotextile and long fiber geotextile, the two geotextile permeability coefficient is basically the same. According to the requirements of the national standard 300g / ㎡ geotextile permeability coefficient for the K * (10 negative side ~ 10 negative three power), K is between 1.0-9.9 values. From the indicators can be seen 300g / ㎡ specifications of the geotextile has a good water filter, can be used for water, filter them.
- Q: How do geotextiles help in preventing weed growth?
- Geotextiles help in preventing weed growth by acting as a physical barrier that blocks sunlight from reaching the soil, thus inhibiting weed seed germination and growth. Additionally, they prevent weed roots from penetrating through the fabric, reducing their ability to establish and thrive in the area.
- Q: What are the factors to consider when designing geotextile-reinforced walls?
- When designing geotextile-reinforced walls, there are several factors that need to be considered. Firstly, the strength and stability of the geotextile material itself is crucial. The geotextile should have sufficient tensile strength and durability to withstand the loads and pressures exerted on the wall. Secondly, the soil characteristics and properties must be thoroughly analyzed. Factors such as soil type, compaction, and shear strength are essential in determining the design of the reinforced wall. The slope of the site and the anticipated slope stability also play a significant role. The angle of inclination and the height of the wall will impact the design and reinforcement requirements. Additionally, proper drainage is vital to prevent water buildup and potential failure of the wall. The design should incorporate adequate measures to ensure effective water management and prevent hydrostatic pressure. Considering the environmental conditions is essential. Factors such as temperature variations, freeze-thaw cycles, and corrosive substances in the soil must be taken into account to ensure the longevity of the geotextile-reinforced wall. Lastly, construction techniques and maintenance requirements should be considered during the design phase. The ease of installation, access for maintenance, and potential future repairs should all be evaluated to ensure the practicality and sustainability of the reinforced wall.
- Q: Can geotextiles be used in coastal erosion control projects?
- Yes, geotextiles can be used in coastal erosion control projects. They are often employed as a part of erosion control systems to stabilize the soil and prevent erosion in coastal areas. Geotextiles are permeable fabrics that are placed on the ground or underwater to reinforce and protect the soil, while allowing water to pass through. They can help in maintaining beach profiles, preventing sediment loss, and reducing wave energy, thus providing effective coastal erosion control.
- Q: What are the specifications for geotextiles in gas venting projects?
- The specifications for geotextiles in gas venting projects typically include factors such as the material's permeability, strength, and durability. The geotextile should have a high permeability to allow gas to pass through while preventing the migration of fine particles. It should also possess adequate strength to withstand the gas pressure and potential stresses. Additionally, the geotextile should exhibit durability to withstand environmental conditions and maintain its functionality over time.
- Q: How do geotextiles help with reinforcement of soil slopes?
- Geotextiles help with the reinforcement of soil slopes by providing a stable and strong barrier that prevents soil erosion. They act as a protective layer, distributing the weight and forces evenly, enhancing the stability of the slope. Additionally, geotextiles separate the soil layers, preventing intermixing and promoting drainage, which further contributes to the reinforcement of the slope.
- Q: Do geotextiles affect soil pH levels?
- No, geotextiles do not affect soil pH levels as they are primarily used for erosion control and soil stabilization rather than altering the chemical composition of the soil.
- Q: National standard geotextile and non - standard how to distinguish
- First of all, the appearance: the national standard geotextile because of the use of high-quality production of large fiber, the production of Dan Shan measured Yao non-astonishing stone products will be dense needle, the appearance of bright white or white. Rather than the standard geotextile generally used in the production of small or small fiber, the product is slightly loose acupuncture, the appearance of dark yellow or gray soil. GB geotextile and non-standard geotextile together through the appearance is easy to distinguish. Second, the strength: the national standard geotextile material is excellent, strong product breaking strength and bursting high strength, the same weight of non-standard geotextile products broken strength and broken broken strong, can be used to tear, items piercing and other methods to distinguish the quality of simple Good or bad. Finally, the price: GB geotextile price is higher than non-standard geotextile, the procurement of less than the market price of geotextiles to be careful.
