Non-woven Geotextiles rau cais cov khoom siv
Khoom Taw Qhia:
Non-woven Geotextiles (tseem hu ua permeable geotextiles, lim geotextiles, non-woven geotextiles), thiab muab faib ua luv fiber needled geotextiles thiab polyester filament geotextiles, gram hnyav nyob rau hauv 100g-1200g, geotextiles yog ib tug nonwoven thiab muaj ntaub.Lub permeable geosynthetics yog tsim los ntawm cov txheej txheem ntawm cov khoom siv tsis-woven, xws li loosening, carding, cluttering (luv fibers interwoven ua ke), netting (normalized entangling thiab fixation), thiab needling.
Khoom nta:
1. Non-woven Geotextile yog siv los cais cov khoom siv nrog lub cev sib txawv (particle loj, faib, sib xws thiab ntom, thiab lwm yam), xws li av thiab xuab zeb, xuab zeb thiab gravel, av thiab pob zeb, thiab lwm yam.
2. Lim thaum dej los ntawm cov av zoo rau hauv cov av ntxhib, siv cov geotextile zoo huab cua permeability thiab dej permeability, kom cov dej los ntawm
3. Dej ntws tawm Nws tuaj yeem tsim cov dej ntws hauv cov qauv av, cov qauv av ntawm cov kua dej ntau dhau thiab cov pa tawm.
4. Reinforcement siv geotextile los txhim kho lub zog tensile thiab tiv thaiv deformation muaj peev xwm ntawm cov av, txhim khu kev ruaj ntseg ntawm lub tsev qauv, txhim kho cov av zoo.
