Geotextile Woven PP Earthwork for Road and Railway

Q: What is the coefficient of friction for nonwoven geotextiles? What is the coefficient of friction between rock and soil?: Geotextile friction coefficient refers to the friction between the two surfaces and the role of the vertical force on a surface ratio. It is related to the roughness of the surface, regardless of the size of the contact area. According to the nature of motion, it can be divided into dynamic friction coefficient and static friction coefficient.

Q: What are the factors affecting the selection of geotextiles?: The factors affecting the selection of geotextiles include the specific application or project requirements, such as the desired strength, durability, and permeability of the geotextile. Other factors include the site conditions, including soil type, slope stability, and water conditions. Additionally, the cost, availability, and environmental considerations of the geotextile should also be taken into account during the selection process.

Q: How do geotextiles contribute to soil improvement in soft ground areas?: Geotextiles contribute to soil improvement in soft ground areas by providing reinforcement and stabilization. They act as a barrier between the unstable soil and the overlying structures, distributing the load and reducing settlement. Additionally, geotextiles allow for water drainage while preventing soil erosion, promoting healthy soil conditions for growth and stability.

Q: How do geotextiles help in preventing soil contamination from chemicals?: Geotextiles act as a protective barrier between the soil and chemicals by preventing their infiltration into the ground. They effectively filter and separate contaminants, allowing water to flow through while retaining harmful substances. This helps in minimizing soil contamination and preserving its quality.

Q: Can geotextiles be used in bridge abutment construction?: Yes, geotextiles can be used in bridge abutment construction. Geotextiles are often used to reinforce soil and provide stability in various construction projects, including bridge abutments. They can be employed to separate different soil layers, prevent erosion, and enhance drainage, thereby improving the overall performance and longevity of the bridge abutment structure.

Q: How do geotextiles prevent soil contamination?: Geotextiles prevent soil contamination by acting as a barrier that separates the soil from potentially harmful substances, such as pollutants or contaminants. It helps to filter and retain these substances, preventing them from leaching into the soil and affecting its quality. Geotextiles also aid in erosion control, reducing the risk of soil contamination caused by sediment runoff.

Q: How do geotextiles help in subsurface drainage?: Geotextiles help in subsurface drainage by acting as a filter and separation layer between the soil and the drainage material. They prevent the soil particles from clogging the drainage system while allowing water to pass through, promoting efficient water flow and preventing waterlogging.

Q: Are geotextiles suitable for use in landfill caps?: Yes, geotextiles are suitable for use in landfill caps. They provide a barrier and filtration system that helps prevent the escape of gases and leachate from the landfill, while also allowing for proper drainage. Geotextiles also help to stabilize the soil and prevent erosion, making them an effective solution for landfill cap construction.

Q: What are the disadvantages of using geotextiles?: There are several disadvantages of using geotextiles. Firstly, geotextiles can be quite expensive compared to other types of erosion control or soil stabilization methods. Additionally, they may require professional installation, which can add to the overall cost. Secondly, geotextiles are not a permanent solution and may degrade over time due to weather conditions and UV exposure. This can lead to the need for frequent replacements, resulting in additional expenses. Lastly, geotextiles may not be suitable for all soil types or project requirements, as they have limitations in terms of load-bearing capacity and effectiveness in certain applications.

Q: 300 grams of non-woven geotextile piercing strength is how much: First of all, according to what you said 300g non-woven geotextile should be polyester staple fiber non-woven geotextile. Polyester staple fiber non - woven geotextile implementation of the national standard GB / T - 2008 standard. According to GB / T-2008 standard anti-puncture strength (standard is CBR burst strength) requirements, 300g national standard geotextile anti-piercing strength should be ≥ 1.5KN.
