- 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: 400g / m2 two cloth a layer of water permeable geotextile technical requirements
- Two cloth a film will not be permeable, the composite film index breaking strength 5kn top broken 1.1kn tear 0.15kn peel 6n / cm or substrate fracture without stripping, the current 2008 standard weight has not been required, the original standard For not less than 360 grams
- Q: How do geotextiles contribute to the efficiency of drainage systems?
- Geotextiles contribute to the efficiency of drainage systems by acting as a filter and separator. They prevent fine particles from clogging drainage pipes and channels, allowing water to flow freely. Additionally, geotextiles help in water infiltration and retention, improving overall drainage performance and reducing the risk of soil erosion.
- Q: What are the design considerations for geotextile-reinforced soil walls?
- Some of the key design considerations for geotextile-reinforced soil walls include the selection and placement of appropriate geotextile materials, determining the required strength and stability of the wall, considering the potential for water drainage and filtration, accounting for settlement and creep behavior, evaluating the impact of external loads and surcharges, and ensuring proper construction techniques are followed. Additionally, considerations for long-term durability, environmental factors, and aesthetic aspects may also be taken into account depending on the specific project requirements.
- Q: How do geotextiles help with sediment filtration in stormwater ponds?
- Geotextiles help with sediment filtration in stormwater ponds by acting as a barrier to prevent sediment from entering the water. They are placed at the bottom of the pond or along the sides to trap sediment particles while allowing water to flow through. This helps in reducing the amount of sediment that settles in the pond, ensuring cleaner water and improving the overall efficiency of the stormwater management system.
- Q: The technical parameters of woven geotextile
- Test items / specifications 0400 Remarks breaking strength (longitudinal) KN / m ≥ 17. Breaking strength (horizontal) KN / m ≥ no special requirements by the meridional 0.7 / 1 longitudinal and transverse elongation at break% ≤ 25 vertical and horizontal trapezoidal torn Strength, KN ≥ 0.180.200.270.340.410.480.600.72 vertical and horizontal CBR top breaking strength, KN ≥ 1.41.62.43.24.04.86.07.5 equivalent aperture O95 (O95) mm0.07-0.5 vertical permeability coefficient cm / sK × (10-1-10-4) K = 1.0-9.9
- Q: How do geotextiles help with soil confinement in erosion control block walls?
- Geotextiles play a crucial role in soil confinement within erosion control block walls by acting as a filter and separator. They prevent soil particles from washing out while allowing water to drain through, thereby reducing hydrostatic pressure and the risk of wall failure. Additionally, geotextiles enhance the overall stability and longevity of the wall by providing reinforcement and preventing soil erosion.
- Q: Neighborhoods: anti-seepage composite geotextile testing need to follow which test specifications, and routine testing items.
- (G / sq.m), film thickness (mm), mass per unit area deviation (%), breaking strength (KN / m), the product quality (GB / T-1998) (KN), the equivalent pore diameter O55 (mm), the vertical permeability coefficient (cm / s), the hydrostatic pressure (Mpa), the tearing strength (KN), the CBR breaking strength (KN) The And the front two said the basic almost, but hope that a detailed description can make you more clearly point.
- Q: Geotextile puncture test standard
- Staple stitch filament piercing filament woven weaving
- Q: JTGF80 / 1-2004 "standard" 4.5 Geosynthetics in the treatment of the measured items in the "anchoring length", in the construction design diagram, the provisions of the value of the allowable deviation should be how to implement? Question added: Sorry! I missed a few words. When the construction design is not indicated, the specified value, the allowable deviation value should be implemented? JTGF80 / 1-2004 "standard only write to meet the design, construction requirements. I did not say that the design of the length of the anchorage is how much, can not find the construction technical specifications. So I do not know the provisions of the value of how to allow deviation? More
- Specifically not less than the specified value, does not exceed the allowable deviation. This is the so-called construction by specification! You refer to JTG assessment standard -2004 is correct! I have the data to let you refer to the next / geogrid and geotextile landscape is greater than or equal to 50cm, vertical is greater than or equal to 150com
