Artificial Lake Anti-seepage Cov Lus Pom Zoo Ua Ke - Composite Geomembrane thiab Pam Bentonite Waterproof
Tam sim no, feem ntau ntawm cov toj roob hauv pes ua kom zoo nkauj, dej ntws, pas dej da thiab pas dej kom zoo nkauj muaj teeb meem to. Kev poob ntawm cov dej hauv thaj av ua rau lub hauv paus tom ntej ntsuab tsis zoo, kev kho dej tsis zoo tuaj yeem tsim kho, thiab lwm cov vaj tse nyob ib puag ncig cuam tshuam. Kev tsim kho yog teeb meem.
Cov pas dej cuav yog qhov nyuaj hauv cov qauv thiab muaj ntau yam duab. Feem ntau, muaj cov kwj deg uas dej ntws, cov kab tawm, cov kob dej hiav txwv uas muaj cov duab sib txawv, cov pob zeb uas tsis ruaj khov kho kom ruaj khov, muaj qhov pom toj roob hauv pes, thiab toj roob hauv pes tiv thaiv vaj huam sib luag zoo li dej tsis tuaj yeem. Vim tias qhov kev daws teeb meem tsis sib xws ntawm lub hauv paus, tawg thiab to los yog tshwm sim, cov nyhuv los tiv thaiv nplooj ntawv tsis tuaj yeem ua tiav, thiab tus nqi tau siab thiab lub sijhawm tsim kho tau ntev. Yog li yuav ua li cas los daws cov teeb meem to dej ntawm toj roob hauv pes pas dej lossis pas dej cuav? Qhov sib xyaw geomembrane thiab bentonite waterproof pam yog kev sib koom ua ke!
Qhov sib xyaw geomembrane yog dej-impermeable cov khoom ua los ntawm cov khoom siv geotextile thiab geomembrane. Nws yog tsuas yog siv rau anti-seepage. Qhov sib xyaw geomembrane tau muab faib ua zaj duab xis thiab zaj duab xis, qhov dav ntawm 4-6m thiab qhov hnyav ntawm 200- 1500g / m2, lub cev muaj zog thiab lub cev muaj zog xws li lub zog tensile, kua muag tsis kam thiab tawg, tuaj yeem ua tau raws li cov kev xav tau ntawm civil engineering. xws li dej txuag dej, hauv nroog, kev tsim vaj tsev, tsheb thauj mus los, chaw nres tsheb ciav hlau, qhov av, thiab lwm yam Vim tias nws xaiv cov ntaub ntawv polymer thiab ntxiv cov thev naus laus zis ntau lawm los tiv thaiv kev laus, yog li nws tuaj yeem siv hauv qhov tsis muaj kev tiv thaiv ib puag ncig kub.
Bentonite waterproof pam yog ib yam tshiab ntawm cov khoom siv tsis tau zoo. Bentonite muaj cov cohesiveness zoo thiab o. Tus qauv sab hauv yog txheej txheej ntawm cov ntaub tsis-ntaub. Tom qab cov dej nqus, nws nthuav mus rau hauv qhov chaw tsis txaus los ua lub ntsej muag nruj, yog li ua tiav dej nres. nyhuv. Vim tias nws cov yam ntxwv zoo, nws kuj tseem tau teev tseg ua thawj xaiv rau txheej txheem dej pas dej ecological. Cov khoom siv yog pam vov waterproofing daim nyias nyias ua los ntawm sib xyaw ua ke ntawm sodium sodium-bentonite hais thiab sib haum admixtures rau hauv cov ntaub ntawv nyoos, thiab kho cov bentonite hais nruab nrab ntawm cov geotextile thiab yas ntaub npuag los ntawm rab koob punching txheej txheem thiab khoom siv. Cov. Bentonite waterproof pam muaj tag nrho cov yam ntxwv ntawm cov ntaub ntawv geotechnical thiab zoo kawg nkaus waterproof (permeability) cov yam ntxwv. Lub npe mineralogical ntawm bentonite yog montmorillonite, thiab ntuj bentonite tsuas yog muab faib ua sodium thiab calcium raws cov tshuaj lom neeg muaj pes tsawg leeg. Bentonite muaj cov cuab yeej ntawm o nrog dej. Thaum cov calcium-based bentonite nthuav dav, nws txoj kev nthuav dav tsuas yog 3 zaug ntawm nws tus kheej lub ntim, thaum sodium-based bentonite nqus tsib zaug nws qhov hnyav thaum nws ntsib dej, thiab nthuav mus rau 15-17 zaug lossis ntau dua. Cov sodium bentonite yog xauv rau hauv nruab nrab ntawm ob txheej ntawm cov khoom siv geosynthetic los tiv thaiv thiab ntxiv dag zog rau GCL kom muaj qee yam ntawm txhua qhov ntawm lub zog shear. Qhov bentonite hais nrawm nrawm nrog dej kom tsim tau txoj kev tsoos xim sib txawv. Raws li kev txwv ntawm ob txheej ntawm geotextiles, bentonite yog hloov los ntawm kev tsis sib haum xeeb mus rau kom nthuav tawm. Qhov tshwm sim ntawm kev nqus dej mus txuas ntxiv yog ua kom cov bentonite txheej nws tus kheej ntom, yog li muaj Waterproof.
Composite geomembrane yog siv dav hauv channel saib cov phiaj xwm kev tiv thaiv. Xyoo tsis ntev los no, cov ntawv thov dav thiab muaj txiaj ntsig ntawm geosynthetics hauv kev txua hluav taws xob, tshwj xeeb hauv kev tswj dej nyab thiab cawm cov haujlwm, tau ua rau muaj kev cuam tshuam ntawm cov engineers thiab cov kws kho. Rau cov ntawv thov thev naus laus zis ntawm geosynthetics, lub xeev tau tso cov txheej txheem kev cai ua tau los ntawm cov txheej txheem ntawm kev tiv thaiv kev tiv thaiv, kev tiv thaiv kev lim, kev lim dej, txhawb nqa, tiv thaiv, thiab lwm yam, uas tau ua kom zoo tshaj qhov nce qib thiab thov cov ntaub ntawv tshiab. Cov khoom siv tau siv dav hauv qhov pom kev tiv thaiv kev ua haujlwm ntawm cov chaw dej, thiab sib xyaw nrog kev tsim kho, daim ntawv thov thev naus laus zis ntawm geomembrane tau sib tham.
Cov sib xyaw geomembrane (cov yeeb yaj kiab tiv thaiv-tiv thaiv nplooj ntawv) tau muab faib ua ib daim ntaub ib qho thiab ob daim ntaub ib zaj duab xis, qhov dav yog 2m-6m, qhov hnyav yog 200g1500g / m2, thiab cov khoom siv lub cev thiab lub cev xws li tensile, kua muag tsis kam thiab tawg ntho muaj ntau. Cov khoom muaj cov yam ntxwv ntawm lub siab muaj zog, zoo elongation kev ua tau zoo, loj deformation modulus, acid thiab alkali tsis kam, corrosion tsis kam, laus tiv thiab zoo anti-seepage zoo. Nws tuaj yeem ua kom tau raws li cov kev xav tau ntawm kev ua haujlwm hauv pej xeem xws li kev tiv thaiv tawm tsam, cais tawm, ntxiv dag zog, tiv thaiv kev tawg thiab tiv thaiv hauv kev txuag dej, hauv nroog, kev tsim vaj tsev, tsheb thauj mus los, subway, tunnel thiab engineering kev tsim kho. Nws feem ntau siv rau kev tiv thaiv-saib nplooj ntawv ntawm lub pas dej thiab cov kwj dej, nrog rau kev tawm tsam ntawm cov khib nyiab.
