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: Can geotextiles be used in bridge construction?
- Yes, geotextiles can be used in bridge construction. Geotextiles are often used as a separation layer between the bridge substructure and the underlying soil to prevent soil erosion and enhance stability. They can also be used as a reinforcement material to improve the strength and stability of bridge foundations and slopes. Additionally, geotextiles can help with filtration, drainage, and erosion control in bridge construction projects.
- Q: What is the purpose of using geotextiles?
- The purpose of using geotextiles is to provide a wide range of functions in different construction and engineering applications. These functions include soil stabilization, erosion control, filtration, drainage, separation, and reinforcement. Geotextiles act as a protective barrier, improving the performance and lifespan of infrastructure projects such as roads, embankments, retaining walls, and landfills.
- Q: How do geotextiles help with reinforcement of embankments?
- Geotextiles help with the reinforcement of embankments by providing stability, preventing soil erosion, and improving overall durability. They act as a barrier between soil layers, distributing loads and reducing the risk of settlement or slope failure. Additionally, geotextiles allow for better drainage, reducing the buildup of water pressure behind the embankment and minimizing the possibility of landslides.
- Q: How do geotextiles contribute to soil separation?
- Geotextiles contribute to soil separation by acting as a barrier between different types of soil, preventing them from mixing and maintaining their individual characteristics.
- Q: What are the specifications for geotextiles in railway projects?
- The specifications for geotextiles in railway projects generally include requirements for strength, durability, permeability, and filtration. These geotextiles should have sufficient tensile strength to withstand the dynamic loads imposed by trains and maintain their integrity over time. They should also be resistant to degradation caused by UV exposure, chemical exposure, and biological factors. The permeability of geotextiles is crucial to ensure proper drainage and prevent water accumulation, which can lead to instability. Additionally, the geotextiles should possess excellent filtration properties to prevent the migration of fine particles and maintain the stability of the railway subgrade.
- Q: What are the different geotextile reinforcement techniques for slopes?
- There are several geotextile reinforcement techniques for slopes, including slope stabilization using geotextile wraps, slope reinforcement with geotextile grids, and slope erosion control using geotextile blankets. These techniques involve the use of geotextile materials to enhance the stability and performance of slopes, preventing erosion and promoting long-term stability.
- Q: How do geotextiles improve soil stability?
- Geotextiles improve soil stability by providing reinforcement and separation. They prevent soil erosion, retain moisture, and distribute loads, ultimately enhancing the overall strength and stability of the soil.
- Q: Are geotextiles suitable for use in high-temperature environments?
- Yes, geotextiles are suitable for use in high-temperature environments. Geotextiles are designed to withstand a wide range of temperatures, including high temperatures. They are often used in applications such as road construction, erosion control, and drainage systems in hot climates without any issues.
- Q: Are geotextiles resistant to hydrostatic pressure?
- Yes, geotextiles are generally resistant to hydrostatic pressure.
- Q: Can geotextiles be used in erosion control in river channel stabilization?
- Yes, geotextiles can be used in erosion control in river channel stabilization. Geotextiles are engineered fabrics that can be placed in river channels to prevent soil erosion and stabilize the riverbanks. They help in reducing the velocity of water flow, trapping sediment, and promoting vegetation growth, thereby effectively controlling erosion in river channels.
