1. Hais txog kev siv cov khoom siv geotextile no, nws lub luag haujlwm tseem ceeb yog los ua ib qho kev thaiv thiab lim cov ntaub ntawv kom cais cov av mus tas li ntawm cov dej, thaum kawg tiv thaiv cov tsub zuj zuj ntawm cov dej siab, thiab tom qab ntawd tiv thaiv dej los ntawm kev tsim corrosion.Geotextiles kuj tseem siv tau zoo los txhim kho cov qoob loo tsim khoom, lub vaj, thiab tsev cog khoom.Lawv cov khoom tiv thaiv txo qhov kev xav tau ntawm kev siv tes ua haujlwm rau cov tshuaj tua kab, thiab ua raws li qhov tsawg kawg nkaus txwv.
Tsis tas li ntawd, geotextile ntsig txog geotextiles ua raws li kev ywj pheej hauv av tsis muaj dej thaiv thiab cov ntaub ntawv lim dej, thaum kawg tiv thaiv kev sib sau ntawm cov dej siab, thiab tom qab ntawd tiv thaiv kev ua dej los ntawm kev tsim corrosion.
Qhov tshwm sim uas cov kab mob ntawm cov filament geotextile nce tsis tu ncua nrog lub sij hawm nyob rau hauv lub tensile kev txiav txim ntawm ib tug ruaj khov sab nraud quab yuam yog hu ua creep.Thaum siv nyob rau hauv tej yaam num uas ua lub luag hauj lwm nyob rau hauv filtration, kua, thiab barrier, lub filament geotextile yog sai sai rau ib tug ruaj khov tensile sab nraud quab yuam.Yog li ntawd, pupation yam ntxwv ntawm filament geotextile yog xam raws li qhov Performance index rau xaiv cov ntaub.Cov filament geotextile plays lub luag haujlwm txhawb nqa, Nws cov yam ntxwv creep muaj qhov cuam tshuam loj rau nws qhov kev txhawb zog.Filament geotextiles yog siv los txhawb cov embankments ntawm cov hauv paus mos.Filament geotextiles tau raug rau qee qhov nro.Tom qab ib lub sij hawm, cov filament geotextile undergoes loj deformation, uas yuav cuam tshuam rau stability ntawm lub embankment.Ib feem ntawm qhov kev puas tsuaj tuaj yeem tshwm sim, xws li deformation tshaj nws qhov tawg elongation, thiab cov kab nrib pleb geotextile tawg, uas tuaj yeem ua rau muaj kev puas tsuaj tag nrho rau embankment.Nyob rau hauv tej yaam num, Nws feem ntau yuav siv sij hawm 5 mus rau 7 xyoo los sib sau ua ke lub hauv paus mos.Thaum lub sij hawm no, lub creep ntawm filament geotextile tsis tuaj yeem tshaj li tus nqi npaj.
Kev siv qhov tseeb muaj txiaj ntsig zoo.
Thiab kev siv cov geotextiles hauv cov dej txuag dej muaj txiaj ntsig zoo, vim tias cov khoom siv no muaj cov dej zoo, siv sijhawm ntev, thiab muaj kev ntseeg siab ntawm cov kav ntev.
Cov khoom lag luam no tuaj yeem tsim cov dej ntws tshwj xeeb hauv cov av loj, uas tuaj yeem ua kom ntseeg tau qhov tseeb ntawm cov kua dej ntau dhau thiab qee cov pa roj thaum tshem tawm lwm yam pov tseg.Qhov no tuaj yeem tiv thaiv cov khoom seem hauv sab hauv ntawm cov av loj thiab muaj qee yam cuam tshuam rau cov qauv ntawm cov av loj.Qhov no tsis tsuas yog cuam tshuam rau cov qauv ntawm cov av loj, tab sis kuj tseem tuaj yeem muaj kev cuam tshuam loj rau kev tsim khoom tom ntej.
Rau cov av, thaum siv cov khoom, nws tseem tuaj yeem tiv thaiv deformation ntawm cov av, uas yog qhov tseem ceeb heev rau kev txhim kho cov deformation tsis kam.Rau qee qhov kev tsim kho, kev siv geotextiles tuaj yeem txhim kho kev ruaj ntseg ntawm cov tsev.
Tsis tas li ntawd, geotextile kuj tseem muaj txiaj ntsig zoo rau kev txhim kho cov av loj, uas tuaj yeem ua kom cov av loj tuaj yeem du thaum lub sijhawm tsim kho, thiab cov av loj tuaj yeem tso tawm qee cov ntaub ntawv pov tseg los tiv thaiv lawv los ntawm cov seem hauv av, ua rau nyob rau hauv ib qho kev cuam tshuam rau cov qauv ntawm cov av loj.
Qhov tseeb, cov khoom siv dej tsis zoo geotextile xws li filament geotextile feem ntau yog siv rau hauv kev tsim khoom, vim tias lawv cov huab cua permeability thiab dej permeability yog qhov zoo, thiab lawv nrov heev nrog kev lag luam.Lawv cov nyhuv waterproof kuj nrov heev nrog manufacturers.
Yog tias cov khoom siv raw siv rau cov khoom yog qhov tshwj xeeb thiab qee cov polypropylene lossis polyester fibers tau siv los ua roj, cov nyhuv ntawm corrosion kuj tseem ceeb heev, uas tuaj yeem txhim kho cov khoom muaj peev xwm tiv thaiv corrosion thiab zam cov tsos ntawm corrosion rau qee yam khoom. hauv av.
Geotextiles feem ntau yog siv rau hauv ntau qhov haujlwm hauv kev tsim vaj tse los pab hauv lawv cov khoom, vim lawv tuaj yeem txhim kho lub zog tensile thiab deformation tsis kam ntawm av.
Qhov tseeb, hom dej tsis zoo geotextile no tau siv dav, tsis yog hauv cov dej txuag dej xwb, tab sis kuj muaj qee qhov kev tsheb ciav hlau thauj mus los zoo tib yam, nrog rau kev tsim kho, kom ntseeg tau tias cov txiaj ntsig ntawm cov khoom tuaj yeem lees paub los ntawm cov chaw tsim khoom.
