Dab tsi sib txawv ntawm Woven geotextile thiab non-woven geotextile?
Geotextile yog dej-permeable geosynthetic cov khoom ua los ntawm cov hluavtaws ua ke los ntawm rab koob xuas nrig lossis nws. Cov khoom tiav yog daim ntaub-zoo li, yog li nws hu ua geotextile, nrog qhov dav ntawm 4 txog 6 meters thiab qhov ntev ntawm 50 txog 100 meters.
Geotextiles tau muab faib ua: non-woven geotextiles thiab woven geotextiles
1. Cov ntaub qhwv tsis-geotextiles tau muab tso rau hauv lub network los ntawm filament lossis staple fiber ntau los ntawm cov khoom siv sib txawv thiab cov txheej txheem, thiab cov kab hluav taws xob sib txawv (cov fiber filaments) sib cuam tshuam thiab ua kom sib nkag siab tom qab rab koob punching thiab nws. Txheem thiab ua qauv zoo ntawm cov khoom sib txawv, thiab ua kom cov ntaub mos muag, tag nrho, tuab thiab txhav, nrog cov yam ntxwv ntawm cov ntaub, thiab siv qhov no kom ua tiav cov tuab sib txawv kom tau raws li qhov xav tau ntawm kev siv.
Tsis-woven geotextiles muaj cov qhov zoo ntawm cov ntaub thiab qhov sib txuas ua ke, kom cov geotextiles muaj qee qhov dej permeability, hloov tau mus rau deformation, thiab kua muag tsis kam; vim tias cov nplaim mos mos thiab muaj ntau qhov khoob, qhov chaw geotextiles muaj qhov sib tshooj zoo ntawm kev sib txhuam uas tuaj yeem ua rau muaj peev xwm ntxiv Adhesion muaj peev xwm ntawm cov av.
Raws li qhov ntev ntawm filament, nws muab faib ua: filament non-woven geotextile, luv filament tsis-woven geotextile; lawv tuaj yeem ua lub luag haujlwm zoo hauv kev lim dej, cais tawm, ntxiv dag zog, tiv thaiv, thiab lwm yam, yog cov khoom siv geosynthetic dav; Lub zog tensile ntawm filament yog siab dua li ntawm staple, thiab nws tuaj yeem xaiv thiab siv raws li qhov xwm txheej tshwj xeeb.
Tshwj xeeb, qhov tsis-woven geotextile muaj: 1. kev cais tawm 2. pom 3. qhov nqus dej 4. kev ruaj khov 5. kev tiv thaiv 6. kaw
2. Woven geotextiles muaj cov tsawg kawg yog ob pawg ntawm cov yarns mus tib seem (lossis xov yarns). Ib txheej yog raws qhov ntev ntawm qhov ntos (qhov kev taw qhia ntawm cov ntaub, qhov ntev hais tias mus rau) yog hu ua warp, thiab lwm cov teeb tsa cov kev taw qhia ntsug ntawm ntos (uas yog, kab rov tav) yog hu ua weft yarn, uas thaus cov khoom tiav ua tiav xws li daim ntaub. Weaving warp thiab weft yarns rau hauv cov ntaub sib txawv nrog cov cuab yeej sib txawv weaving, sib txawv tuab tuab thiab densities raws li kev sib txawv ntawm kev siv. Feem ntau hais lus, muaj nyias cov geotextiles, thiab lawv muaj lub zog tensile muaj zog heev hauv ob qho chaw qhia ntsug thiab kab rov tav. Lub zog (feem ntau, qhov kev sib zog tensile hauv qhov ntev qhov kev taw qhia yog qhov ntau dua li qhov kev qhia ntawm latitude), thiab nws tseem muaj kev ruaj ntseg zoo.
Woven geotextiles tau muab faib ua: cov khoom tiv thaiv geotextiles thiab tsis tsim kev tiv thaiv geotextiles raws li kev ua haujlwm weaving sib txawv.
Lub zog tensile ntawm lub zog tiv thaiv geotextile yog ntau dua li qhov tsis muaj kev tiv thaiv ntawm cov geotextile thiab qhov zoo tib yam geotextile.
Tshwj xeeb, lub luag haujlwm tseem ceeb ntawm spinning geotextiles yog qhov cuab lub zog ntawm geotechnical engineering, uas muaj cov haujlwm ntawm dav hlau cais thiab tiv thaiv, tab sis tsis muaj cov haujlwm ntawm dav hlau tso.
Raws li cov xwm txheej saum toj no, tuaj yeem pom tias lub luag haujlwm ntawm geotextiles yog cais tawm, ntxiv dag zog, tiv thaiv, ntws, lim, thiab ze. Vim tias qhov sib txawv ntawm txhua qhov project, cov geotextiles uas yuav tsum muaj sib txawv, thiab cov txheej txheem kev tsim kho yog txawv. Yog tias nws yog, ces nws yuav tsum tau xaws, thiab nws yuav tsum muaj kev ruaj ntseg; yog tias nws yog kev rho tawm, ua paug tawm, lim av, nws yog OK siv cov hlau xaim los yog pam vov 10cm, tab sis nws yog qhov zoo tshaj plaws los tseem xaws.
