Application of silk geotextile in the construction of sponge city

Number of hits:1032019-01-05 00:00:00

In the newly developing sponge city construction, geotechnical synthetic materials such as silk geotextiles should play the functions of downward infiltration, reverse filtration, etc. to ensure that rainwater effectively seeps into the soil, minimizing the rainfall discharged into the pipeline system; For the measures of "storage and net", geotechnical synthetic materials such as silk geotextiles should be able to perform the functions of water storage and clean water, ensure that rainwater can be effectively retained as much as possible, and work with sand and stone to purify water quality and effectively store rainwater. Good hydraulic conditions and anti-filtration conditions ensure that it is not easy to block and achieve the goal of comprehensive utilization of rainwater.



Silk geotextiles have good mechanical functions, good water permeability, anti-corrosion, anti-aging, isolation, anti-filtration, drainage, protection, stability, reinforcement and other functions, can adapt to uneven grassroots, can resist the construction of external forces damage, creep smaller, Can still maintain the original function under long-term load. Moreover, filament geotextiles have high UV resistance and strong high temperature resistance. Gaowenda has 230 °C. At high temperatures, they still maintain structural integrity and original physical properties. The filament geotextiles are thick and acupuncture molding., with good plane drainage and vertical permeability, This performance can still be maintained after many years.
