Thaum tham txog lub luag hauj lwm ntawm yas zaj duab xis nyob rau hauv waterproof thiab thermal rwb thaiv tsev, peb yuav tsum xub xav txog impermeable ntiaj teb zaj duab xis.Hom geomembrane no muaj npe nrov rau nws qhov kev ua tau zoo heev thiab tuaj yeem siv tau rau hauv ntau lub ntiaj teb kev ua dej num lossis cov kwj dej.Tej zaum peb yuav pom cov ntaub tsis-woven hauv ntau zaus.Geomembrane yog cov khoom siv tshuaj fiber ntau luv luv.
Geomembrane tuaj yeem nthuav dav rau qee qhov thiab tuaj yeem siv tau ntau qhov chaw.Tom qab cov geomembrane ua ke nrog cov yas zaj duab xis, peb hais tias qhov zoo ntawm cov yeeb yaj kiab yas qub tuaj yeem txhim kho tau zoo, thiab tuaj yeem ua tau raws li peb xav tau ntau dua.Cov khoom no feem ntau hu ua geomembrane.Thaum cov khoom siv ntxiv, kev sib txhuam quab yuam ntawm qhov chaw sib cuag tuaj yeem nce ntxiv, thiab txheej txheej tiv thaiv tuaj yeem tsim lub xeev ruaj khov dua.
Geomembrane feem ntau yog cov khoom siv hluav taws xob luv luv
Tsis tas li ntawd, geomembrane tuaj yeem tiv taus qee yam tshuaj tiv thaiv sab nraud thiab muaj kev tiv thaiv corrosion zoo.Txawm tias muaj zog acid ib puag ncig, qee hom geomembrane tuaj yeem khaws cia rau lub sijhawm ntev.Feem ntau hais lus, cov ntaub ntawv geomembrane ntshai heev ntawm acidic, alkaline lossis ntsev ib puag ncig.Yog tias koj xav siv mulch, nws yog qhov zoo tshaj rau muab tso rau hauv qhov chaw tsis muaj hnub ci ncaj qha.
Vim tias nws tuaj yeem ua rau lub neej ua haujlwm ntev ntawm geomembrane thiab zam cov ntaub ntawv khaws cia, tsuas yog ua li no kom cov geomembrane zam cov tshuaj tiv thaiv.Lub hnub ci ntev ntev tuaj yeem ua rau qhov kub thiab txias ntawm geomembrane, yog li nws yuav ua rau cov qauv ntawm geomembrane tawg.Nws yuav tsis zoo li tias muaj qhov sib txawv loj, tab sis qhov tseeb, qhov xwm txheej ntawm geomembrane tau hloov pauv.
Nrog rau txoj kev loj hlob ntawm kev lag luam, daim ntawv thov ntawm geomembrane thiab geotextile yog ntau dua thiab dav, feem ntau yog siv rau hauv kev tsim kho vaj tse, dej phwj kho cog, kev tiv thaiv dej ntws tawm, qhov project subway thiab lwm yam dej num.Dab tsi yog qhov txawv ntawm geomembrane thiab geotextile thaum siv geotextile?Cia peb saib.
Ntawd yog, cov yam ntxwv sib txawv:
1. Cov yam ntxwv ntawm geomembrane:
Geomembrane yog ib yam khoom siv los tiv thaiv cov dej ntws los ntawm cov yas zaj duab xis thiab cov ntaub tsis-woven.Qhov kev ua tau zoo los tiv thaiv kev ua haujlwm ntawm cov khoom siv tshiab geomembrane feem ntau yog nyob ntawm qhov kev ua tau zoo ntawm cov yeeb yaj kiab yas.
1) Nws muaj kev tiv thaiv zoo rau ib puag ncig kev ntxhov siab tawg thiab tshuaj lom neeg corrosion.
2) Qhov kub thiab txias ntau thiab ua haujlwm ntev.
3) Kev tiv thaiv kev tawm tsam thiab cov dej ntws tawm tau teeb tsa los ua haujlwm ntawm lub tshuab lub cev thiab muaj cov haujlwm ntawm kev sib cais thiab kev txhawb zog.
4) High composite zog, siab tev lub zog thiab zoo puncture kuj.
5) Lub peev xwm ua kom muaj zog, kev sib txhuam loj coefficient thiab me me linear expansion coefficient.
2. Cov yam ntxwv ntawm geotextile
Geotextiles, tseem hu ua geotextiles, yog permeable geosynthetics ua los ntawm tib neeg tsim fibers, koob los yog braids.Geotextile yog ib hom tshiab ntawm geosynthetics.Cov khoom tiav yog daim ntaub, feem ntau 4-6 meters dav thiab 50-100 meters ntev.Geotextiles muab faib ua geotextiles thiab non-woven geotextiles.
1) Tam sim no, hluavtaws fibers siv nyob rau hauv geotextile ntau lawm muaj xws li polyamide fiber, polyester fiber, polypropylene fiber, polypropylene fiber, thiab lwm yam., tag nrho cov uas muaj zog faus thiab corrosion kuj.
2) Geotextile yog ib yam khoom siv permeable nrog kev lim dej zoo thiab kev sib cais ua haujlwm.
3) Nonwoven geotextile muaj kev ua haujlwm zoo vim nws cov qauv fluffy.
4) Geotextile muaj qhov zoo tiv thaiv, yog li nws muaj kev tiv thaiv zoo.
5) Geotextile muaj kev sib txhuam coefficient zoo thiab lub zog tensile, thiab muaj kev ua haujlwm ntawm geotextile qhov cuab lub zog.
2 Cov dej permeability sib txawv:
Geomembrane yog impermeable, thaum geotextile yog permeable.
3 Cov khoom sib txawv:
Geomembranes yog cov ntawv sib txawv ntawm cov thicknesses ua los ntawm cov khoom siv molecular siab lossis roj hmab los ntawm cua sov extrusion lossis tshuab molding.Lawv yog cov impermeable membranes ua los ntawm high thiab tsawg ntom polyethylene, EVA, thiab lwm yam Geotextiles yog polyester, acrylic, thiab lwm yam. Non-woven fabrics processed by spinning, card khaub ncaws los yog tshuab woven fabrics, non-woven fabrics los yog spinning, polyester, polypropylene, acrylic fiber, nylon, thiab lwm yam.
4, Kev ua tau zoo sib txawv:
Geotextiles muaj kev lim dej zoo, kev tso dej, kev sib cais, kev txhawb zog, kev tiv thaiv kev tiv thaiv thiab kev tiv thaiv, thiab yog lub teeb hauv qhov hnyav, siab tensile lub zog, zoo nyob rau hauv huab cua permeability, siab kub thiab laus tiv taus.
Geomembrane yog cov khoom siv polymer hloov tau yooj yim nrog lub ntiajteb txawj nqus me me, muaj zog ductility, muaj zog deformation adaptability, corrosion kuj, tsis kub tsis kam thiab zoo Frost.
Lub hom phiaj sib txawv:
Geotextiles feem ntau yog siv rau kev txhawb nqa, kev sib cais, kua dej, pom thiab kev tiv thaiv.
Geomembrane feem ntau yog siv rau sealing, muab faib, seepage tiv thaiv thiab tiv thaiv tawg.
