1. Introduction of PP Woven Geotextile for Tunnel Engineering:
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 aid in the reduction of pore water pressure?
- Geotextiles aid in the reduction of pore water pressure by providing a barrier that allows water to flow through while preventing the movement of fine soil particles. This helps to maintain the stability of soil structures, as the geotextile acts as a filter, allowing excess water to drain away and reducing the build-up of pressure within the soil.
- Q: Can geotextiles be used in erosion control in agricultural fields?
- Yes, geotextiles can be used effectively in erosion control in agricultural fields. Geotextiles act as a physical barrier that prevents soil erosion by stabilizing the soil and reducing the impact of water flow. They can be used to reinforce slopes, control sedimentation, and provide long-term soil stabilization. Additionally, geotextiles are permeable, allowing water to pass through while retaining soil particles, making them an ideal solution for erosion control in agricultural fields.
- Q: What are the key considerations for geotextile installation in cold climates?
- Some key considerations for geotextile installation in cold climates include selecting a geotextile material that is designed for cold weather conditions, ensuring proper site preparation and ground stabilization, protecting the geotextile from frost heave or ice damage, and taking into account the potential for snow accumulation and removal on the geotextile surface. Additionally, considering the impact of freeze-thaw cycles and designing proper drainage systems are crucial for successful geotextile installation in cold climates.
- Q: How do geotextiles affect soil nutrient availability?
- Geotextiles can have both positive and negative effects on soil nutrient availability. On one hand, geotextiles can help retain nutrients in the soil by preventing their leaching and runoff, thus promoting their availability for plant uptake. On the other hand, if geotextiles are impermeable to water and air, they can hinder nutrient exchange processes and microbial activity, ultimately reducing nutrient availability in the soil. Therefore, the impact of geotextiles on soil nutrient availability depends on their design and application.
- Q: How do geotextiles help with soil confinement in erosion control mats?
- Geotextiles help with soil confinement in erosion control mats by providing a stable and permeable layer that prevents soil erosion. They act as a barrier, holding the soil particles in place while allowing water to pass through, thereby reducing surface runoff and promoting root growth. This prevents the displacement of soil and helps in establishing vegetation, ultimately preventing erosion and improving soil stabilization.
- Q: How do geotextiles help with soil stabilization in foundation construction?
- Geotextiles help with soil stabilization in foundation construction by providing reinforcement and separation functions. They act as a barrier between different soil layers, preventing their intermixing and maintaining their structural integrity. Additionally, geotextiles improve the load-bearing capacity of the soil by distributing the applied loads more evenly, reducing settlement and increasing stability.
- Q: How do geotextiles help with reinforcement of soil slopes?
- Geotextiles help with the reinforcement of soil slopes by providing stability and preventing erosion. They are placed between layers of soil to distribute the load and strengthen the slope. The geotextiles act as a barrier, separating different soil layers and preventing the movement of fine particles. This helps to improve the overall strength and integrity of the slope, reducing the risk of landslides and soil erosion.
- Q: What are the factors to consider when designing geotextile-reinforced slopes?
- When designing geotextile-reinforced slopes, several factors need to be considered. These factors include the type and strength of the soil, the slope angle, the water conditions, the expected load and stress on the slope, the desired vegetation cover, and the available space for construction. Additionally, the design should account for the potential for erosion and the need for drainage to prevent water buildup. The selection of appropriate geotextile materials and installation techniques is also crucial for ensuring long-term stability and effectiveness of the reinforced slope.
- Q: What causes the geotextile aging phenomenon
- Gundam has the characteristics of the product we are all obvious, both in the highway, dams, railways and many other occasions have a very strong product features, and the performance is very outstanding, geotextile is an irreplaceable geotechnical material. Although the geotextile has unparalleled advantages, but the product is not perfect that any product has more or less problems or less, geotextile is the same, its aging problem has been with us, then in the end what causes Geotextile aging? Geotextile aging problem refers to the geotextile in the sun by the smell, temperature changes, biological erosion, chemical corrosion, moisture and other external factors, so that the geotextile strength and performance gradually weakened, loss of seepage effect. UV radiation intensity changes with the intensity of solar radiation, geotextile aging speed with the intensity of UV radiation and speed. Synthetic polymer polymer is concerned, the sun radiation is the main factor in the degradation of polymer degradation. UV radiation in the sun is the most important factor in the aging of the fabric. The ultraviolet radiation causes the polymer to produce a photooxidative decomposition reaction, especially ultraviolet light at a wavelength of 290 to 400 mPm, which has a significant decomposition effect on the polymer , Because the geotextile in the range of ultraviolet light energy is higher than the polymer chemical steamed broken the required energy, so the polymer material aging is very obvious.
- Q: How are geotextiles used in sports field construction?
- Geotextiles are used in sports field construction to enhance the stability, drainage, and overall performance of the playing surface. They are typically installed as a layer between the subgrade and the topsoil, acting as a barrier to prevent the mixing of different soil layers while still allowing water to permeate through. This helps in preventing the formation of puddles and maintaining a consistent playing surface. Additionally, geotextiles can aid in soil stabilization, reducing the risk of erosion and promoting better turf growth.
