Filament geotextile yog ib puag ncig-phooj ywg cov khoom siv hauv tsev yam tsis muaj tshuaj ntxiv thiab kev kho cua sov.Nws muaj cov khoom siv zoo, cov dej zoo permeability, corrosion kuj, kev laus tsis kam, yoog mus rau qhov tsis sib xws hauv cov chav kawm, tiv thaiv kev tsim kho sab nraud, tsis tshua nkag siab, thiab tseem tuaj yeem tswj hwm nws cov haujlwm qub nyob rau hauv lub sijhawm ntev.
Hauv ntau qhov haujlwm, daim ntawv thov ntawm filament geotextile yog qhov dav heev, tab sis cov filament geotextile muaj qee qhov kev pabcuam lub neej, thiab nws lub neej kev pabcuam kuj yog ib qho kev txhawj xeeb ntawm ntau tus neeg siv tam sim no.Qhov txo qis ntawm kev pabcuam lub neej ntawm geotextile feem ntau yog vim kev laus, cov khoom siv, kev tsim kho thiab lwm yam.
1, Yam dab tsi muaj feem xyuam rau lub neej kev pab cuam ntawm filament geotextile
Yuav kom ncua lub neej kev pab cuam ntawm geotextile, cia peb tham txog qhov ua rau geotextile aging.Muaj ntau qhov laj thawj, feem ntau suav nrog cov laj thawj sab hauv thiab sab nraud.Qhov ua rau sab hauv feem ntau yog xa mus rau kev ua haujlwm ntawm geotextile nws tus kheej, kev ua haujlwm ntawm fibers, zoo ntawm additives, thiab lwm yam. Cov sab nraud ua rau feem ntau yog ib puag ncig, xws li lub teeb, kub, acid-puag ib puag ncig, thiab lwm yam. Txawm li cas los xij, kev laus ntawm geotextile tsis yog ib qho tseem ceeb, tab sis qhov tshwm sim ntawm kev sib xyaw ntawm ntau yam, Sab nraud yam muaj feem cuam tshuam rau kev laus ntawm geotextiles.
2, Yuav ua li cas kom ntev lub neej kev pab cuam ntawm filament geotextile
1. Kev xaiv cov khoom siv geotextile yog qhov tseem ceeb heev.Ntau lub tsev me me geotextile siv tsawg dua cov khoom siv hauv tsev, yog li qhov zoo ntawm cov khoom tsim tawm yuav tsis zoo.Yog li ntawd, nws tseem ceeb heev los xaiv ib lub chaw tsim khoom muaj peev xwm geotextile.
2. Cov txheej txheem kev tsim kho yuav tsum raug tswj xyuas nruj raws li kev tsim kho tshwj xeeb ntawm geotextile, txwv tsis pub kev tsim kho zoo thiab kev pabcuam lub neej ntawm geotextile tsis tuaj yeem lav,
3. Ua tib zoo saib seb qhov chaw ntawm cov khoom puas raug puas tsuaj thaum siv, txhawm rau xyuas kom meej tias cov khoom siv tau zoo raws li tus qauv;Lub neej ua haujlwm ib txwm muaj ntawm cov khoom siv geotextile yog tias tom qab 2-3 lub hlis ntawm tshav ntuj, lub zog yuav ploj tag.Txawm li cas los xij, yog tias tus neeg saib xyuas kev laus ntxiv rau geotextile, tom qab 4 xyoos ntawm lub hnub ncaj qha, lub zog poob tsuas yog 25%.Cov geotextile tuaj yeem tswj cov khoom muaj zog tensile nrog cov yas fibers hauv qhov chaw qhuav thiab ntub dej.
4. Ntxiv tshuaj pleev thaiv hnub thiab tiv thaiv kev laus kom hloov mus rau qhov chaw tsim kho.
3, Cov yam ntxwv ntawm filament geotextile
1. Lub zog muaj zog.Vim yog siv cov yas fiber ntau, nws tuaj yeem tuav lub zog txaus thiab elongation nyob rau hauv ntub thiab qhuav.
2. Corrosion kuj, uas tuaj yeem tiv taus corrosion rau lub sijhawm ntev hauv av thiab dej nrog pH sib txawv.
3. Cov dej zoo permeability.Muaj qhov sib txawv ntawm cov fibers, yog li cov dej permeability zoo.
4. Kev ua haujlwm zoo ntawm cov kab mob, tsis muaj kev puas tsuaj rau cov kab mob thiab kab.
5. Kev tsim kho yog yooj yim.Vim tias cov ntaub ntawv yog lub teeb thiab mos, kev thauj mus los, kev tso thiab kev tsim kho tau yooj yim.
6. Ua tiav cov lus qhia: qhov dav tuaj yeem ncav cuag 9m.Tam sim no, nws yog ib qho khoom siv dav hauv tsev, nrog thaj tsam hnyav ntawm 100-800g / m2
