Short-filament geotextiles muaj kev pom zoo heev, thaiv kev tiv thaiv, kev txhawb zog thiab kev tiv thaiv, siab tensile lub zog, zoo permeability, kub tsis kam, khov tsis kam, laus tiv taus, thiab corrosion kuj.Geotextiles muab faib ua geotextiles woven thiab non-woven geotextiles.
Non-woven geotextiles: Non-woven geotextiles yog ua los ntawm filaments lossis luv fibers nteg tawm rau hauv ib lub mesh los ntawm cov khoom sib txawv thiab cov thev naus laus zis.Tom qab acupuncture thiab lwm yam technologies, sib txawv fibers yog intertwined nrog ib leeg, entangled nrog ib leeg thiab tsau los ua cov ntaub.Normalization ua rau cov ntaub mos, plump, khoom, thiab tawv, thiaj li ua tiav cov thicknesses sib txawv kom tau raws li daim ntawv thov.Nws kuj tseem tuaj yeem muaj peev xwm hloov tau zoo heev deformation, muaj peev xwm ua kom lub ntsej muag zoo, lub ntsej muag muag thiab ntau qhov tsis zoo, kev sib txhuam coefficient zoo heev, tuaj yeem ua rau muaj peev xwm ua kom muaj peev xwm adhesion ntawm cov av, thiab lwm yam. .Cov dej noo ntxiv raug tshem tawm, thiab cov tsos yog mos thiab muaj peev xwm tu zoo heev.Raws li qhov ntev ntawm cov filament, nws muab faib ua filament non-woven geotextile lossis luv filament non-woven geotextile.Lawv tuaj yeem ua lub luag haujlwm zoo hauv kev lim dej, thaiv, kev txhawb nqa, kev tiv thaiv, thiab lwm yam, yog cov khoom siv dav siv hauv cov khoom siv geotechnical.Lub zog tensile ntawm filament yog siab tshaj qhov luv luv filament, uas tuaj yeem xaiv thiab siv raws li cov kev xav tau tshwj xeeb.
Woven geotextile (reinforced geotextile): woven geotextile yog tsim los ntawm tsawg kawg yog ob pawg ntawm cov xov paj sib npaug (los yog cov xov paj tiaj), ib pab pawg hu ua warp raws txoj kab ntev ntawm lub loom (kev taw qhia ntawm cov ntaub mus ncig), thiab lwm pab pawg yog npe warp.Lateral placement yog hu ua weft.Cov khoom siv sib txawv thiab cov tswv yim sib txawv yog siv los cuam tshuam cov warp thiab weft yarns rau hauv daim ntaub, uas tuaj yeem woven rau hauv nyias thickness thiab compactness raws li qhov sib txawv daim ntawv thov ntau yam.Lub zog tensile muaj zog (longitude yog ntau dua latitude), nrog kev ruaj ntseg zoo heev.Woven geotextiles tau muab faib ua ob pawg: kev siv zog geotextiles thiab non-reinforced geotextiles raws li kev siv tshuab weaving thiab kev siv warp thiab weft.Lub warp tensile lub zog ntawm reinforced geotextiles yog ntau dua li ntawm cov geotextiles zoo tib yam.Woven geotextiles feem ntau yog siv hauv kev xyaum thiab yog npaj los txhawb ntxiv rau cov haujlwm geotechnical.Lub luag haujlwm tseem ceeb yog txhawm rau txhim kho thiab ntxiv dag zog, thiab nws muaj lub luag haujlwm ntawm lub dav hlau thaiv thiab kev saib xyuas.Nws tsis muaj lub luag haujlwm ntawm lub dav hlau ntws thiab tuaj yeem xaiv raws li lub hom phiaj ntawm daim ntawv thov tshwj xeeb.
Staple fiber koob-punched geotextile: ib yam ntawm txoj cai thiab tsis ncaj ncees lawm weaving thiab industrial fabrics.Nws yog ua los ntawm polyester bent staple fibers nrog ib tug fiber ntau fineness ntawm 6-12 denier thiab ib tug ntev ntawm 54-64 hli raws li raw khoom.Tom qab cov txheej txheem ntawm kev qhib, xov, messing (cov fibers luv yog intertwined nrog ib leeg), nteg (standardized entanglement thiab kho), koob punching thiab lwm yam technologies ntawm cov khoom siv uas tsis yog-woven, nws yog tsim rau hauv daim ntaub.Nws yog tsuas yog siv nyob rau hauv lub zog ntawm railway subgrades, txij nkawm ntawm txoj kev loj pavements, kev tiv thaiv ntawm kev ua si halls thiab dikes, lub barriers ntawm hydraulic siv, tunnels, coastal mudflats, reclamation, ib puag ncig tiv thaiv thiab lwm yam dej num.
