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 are geotextiles affected by UV exposure?
- Geotextiles are affected by UV exposure as prolonged exposure to sunlight can cause degradation and deterioration of their materials. UV rays can weaken the fibers of geotextiles, reducing their strength and overall performance. To combat this, geotextiles are often treated with UV stabilizers or coatings to increase their resistance to UV radiation and extend their lifespan.
- Q:Principle of drainage pipe geotextile
- Plastic blind ditch is made of plastic core wrapped filter cloth group type. Plastic core is a thermoplastic synthetic resin as the main raw material, after modification, in the hot-melt state, through the nozzle extrusion of fine plastic wire, and then through the molding device will be extruded plastic wire at the junction of welding , The formation of three-dimensional network structure. Plastic core with rectangular, hollow matrix, round and round shape of a variety of hollow. The material overcomes the shortcomings of the traditional blind ditch, with good surface opening rate, good water holding capacity, good porosity, good drainage, strong compressive strength, good pressure resistance, good flexibility, good soil deformation and good durability , Light weight, easy construction, workers labor intensity greatly reduced, high construction efficiency, which is generally welcomed by the Engineering Bureau, and has been widely used. Drainage blind tube manufacturers to answer your questions
- Q:How is the strength of geotextiles determined?
- The strength of geotextiles is determined through various laboratory tests, including tensile strength, puncture resistance, and tear strength. These tests evaluate the material's ability to withstand forces and stresses, providing an indication of its overall strength and durability.
- Q:Pudong Chuansha where to sell geotextiles
- Geotextile, also known as geotextile, it is made of synthetic fiber through acupuncture or woven from the permeability of geosynthetics. Geotextile is a new material geosynthetics which one, the finished product for the cloth, the general width of 4-6 meters, the length of 50-100 meters. Geotextile is divided into a spinning geotextile and non-woven filament geotextile. Use geotextile, letter, welcome
- Q:Can geotextiles be used in retaining wall construction?
- Yes, geotextiles can be used in retaining wall construction. They are often used as a reinforcement material to improve the stability and longevity of the wall. Geotextiles can help in preventing soil erosion, providing drainage, and increasing the overall strength of the retaining wall.
- Q:Can geotextiles be used in the protection of pipelines?
- Yes, geotextiles can indeed be used in the protection of pipelines. Geotextiles are commonly used as a protective barrier or liner for pipelines to prevent damage from surrounding soil, rocks, or other external factors. They act as a cushioning layer, distributing the load and reducing the risk of punctures or abrasions to the pipeline. Additionally, geotextiles can help with soil stabilization and erosion control, further enhancing the protection of pipelines.
- Q:What are the factors to consider when designing geotextile tubes for dewatering?
- When designing geotextile tubes for dewatering, several factors need to be considered. These include the type and characteristics of the sediment being dewatered, the desired dewatering efficiency, the required size and number of tubes, the hydraulic conditions, the site-specific environmental factors, and the available equipment and resources. Additionally, factors such as the strength and permeability of the geotextile material, the potential for clogging, and the long-term stability of the dewatering system should also be taken into account.
- Q:What are the specifications for geotextiles used in geosynthetic tubes?
- Geotextiles used in geosynthetic tubes typically have specific specifications that vary depending on the specific application and project requirements. These specifications may include factors such as tensile strength, puncture resistance, permeability, UV resistance, and fabric weight. The specific specifications for geotextiles used in geosynthetic tubes should be determined based on the intended use and the engineering design of the project.
- Q:Are geotextiles resistant to freeze-thaw cycles?
- Yes, geotextiles are typically resistant to freeze-thaw cycles. They are designed to withstand extreme weather conditions, including freezing temperatures and repeated cycles of freezing and thawing without significant deterioration or damage.
- Q:Detailing the geotextile standard which, how to apply their own
- GB GB I specialize in the production of geotechnical materials
