Q: Are geotextiles suitable for use in wetlands?: Yes, geotextiles are suitable for use in wetlands. They are commonly used to stabilize soil, control erosion, and promote vegetation growth in wetland areas. Geotextiles can help retain moisture, filter water, and provide support to prevent soil movement. Additionally, they are often biodegradable or made from natural materials, making them environmentally friendly and suitable for use in wetland ecosystems.

Q: How do geotextiles contribute to soil reinforcement?: Geotextiles contribute to soil reinforcement by providing a strong and stable support system. They prevent soil erosion by acting as a barrier that holds the soil particles in place, preventing them from being washed away by water or wind. Additionally, geotextiles distribute the weight and load of structures evenly, reducing the risk of settlement and improving overall stability.

Q: Are geotextiles resistant to freeze-thaw cycles?: Yes, geotextiles are generally resistant to freeze-thaw cycles. Geotextiles are designed to withstand various environmental conditions, including freezing temperatures and the subsequent expansion and contraction of soil during freeze-thaw cycles. Their properties, such as high tensile strength and durability, allow them to maintain their structural integrity and functionality in such conditions.

Q: How do geotextiles help with soil stabilization in steep slopes?: Geotextiles help with soil stabilization in steep slopes by providing a protective barrier that prevents erosion and helps to retain the soil in place. They act as a reinforcement layer, distributing the load across a wider area, reducing the likelihood of slope failure. Additionally, geotextiles promote water drainage, reducing the potential for saturation and increasing the slope's stability.

Q: How do geotextiles help in preventing clogging of drainage systems?: Geotextiles help prevent clogging of drainage systems by acting as a filter, allowing water to pass through while preventing the entry of fine particles and debris that could potentially clog the system.

Q: Filament spunbond nonwoven geotextile performance requirements for what is the basic item: Filament spunbond acupuncture non-woven geotextile is the implementation of the national standard GB / T-2008 standard. GB / T-2008 standard for filament spunbond acupuncture non-woven geotextile performance requirements of the basic items include: product vertical and horizontal nominal fracture strength (KN / m), vertical and horizontal nominal elongation at break (%) (KN), vertical and horizontal tearing strength (KN), mass per unit area deviation (%), width deviation (%), thickness (mm), vertical permeability coefficient (cm / s), equivalent pore size (O90 (95) / mm). Only the above indicators meet the corresponding GB / T-2008 standard requirements, be considered qualified filament spunbonded non-woven geotextile.

Q: How are geotextiles used in civil engineering projects?: Geotextiles are used in civil engineering projects to provide reinforcement, separation, filtration, and drainage functions. They help stabilize soil, prevent erosion, and improve the performance of structures like roads, embankments, and retaining walls.

Q: What are the factors to consider when designing geotextile-reinforced slopes?: When designing geotextile-reinforced slopes, several factors need to be considered. These include the type and strength of geotextile to be used, the slope angle and height, soil properties, expected loads and stresses, water drainage and erosion control measures, construction methods, and long-term performance requirements. Additionally, site-specific conditions such as climate, vegetation, and nearby structures should also be taken into account. Proper consideration of these factors ensures a safe and stable design that effectively mitigates slope failures and erosion.
