Yuav ua li cas xaiv lub thickness ntawm geomembrane rau irrigation reservoir
Tnws geomembranance ntawm irrigation reservoir yog ua los ntawm polyethylene resin. Cov khoom tseem ceeb yog 97.5 feem pua polyethylene high-density polyethylene, li 2.5 feem pua carbon dub, aging resistance agent, oxygen resistance agent, ultraviolet absorbent, stabilizer thiab lwm yam khoom siv. Nws yog tsim los ntawm cov khoom siv geoproduction tsis siv neeg thiab peb txheej co-extrusion tshuab. Tag nrho cov khoom yog ua raws li Teb Chaws Asmeskas cov qauv GRI thiab ASTM cov qauv ntsuas kev ua tiav ntawm kev tsim khoom, ua tiav cov ntsiab lus, du nto roughness thickness ntawm O. 20mm-4.0mm, dav 1m {{11} }m, kom ua tau raws li kev tiv thaiv ib puag ncig thiab kev huv, kev txuag dej, kev tsim kho, kev tsim vaj tsev hauv nroog, vaj, toj roob hauv pes, petrochemical, mining, ntsev, kev ua liaj ua teb, aquaculture kev lag luam thov kev thov.
Impermeable zaj duab xis nta:
1. Ua tiav qhov dav thiab thickness specifications (thickness 0.2-4mm, dav 1-6m).
2.Excellent kuj rau ib puag ncig kev nyuaj siab cracking kev ua tau zoo.
3. qhov kub thiab txias ntau thiab ua haujlwm ntev.
4. Kev noj qab haus huv thiab kev tiv thaiv ib puag ncig. Nws tsis muaj teeb meem rau tib neeg lub cev thiab tsis ua phem rau ib puag ncig. Nws yog dav siv nyob rau hauv haus dej engineering txawv teb chaws.
Geomembrane ntawm irrigation reservoir yog siv nyob rau hauv dej conservancy engineering thiab kuj siv rau seepage tiv thaiv ntawm lub pas dej ua ke los yog channel, thiab tej zaum kuj siv nyob rau hauv lub cia engineering ntawm kev daws nrog complex tshuaj muaj pes tsawg leeg los yog industrial pov tseg. Geomembrane yog siv nyob rau hauv txawv anti-seepage tej yaam num, thiab lub thickness xaiv kuj txawv. Lub thickness ntawm geomembrane muaj ob qhov yuav tsum tau txiav txim siab. Ib qho yog los tswj cov dej ntws tawm, cov geomemes tuab tuaj yeem txo cov hydraulic gradient thiab yog li txo nws cov permeability; Ntawm qhov tod tes, nws yog tswj nyob rau hauv qhov kev txiav txim ntawm dej siab kom tsis txhob punctured los ntawm cov av hauv qab.
Raws li qhov yuav tsum tau ua, lub thickness ntawm geomembrane nyob ntawm qhov loj ntawm cov dej siab ntawm cov khoom siv membrane, qhov loj me ntawm cov txheej hauv qab, thiab cov elastic modulus ntawm cov khoom siv membrane nws tus kheej thiab qhov kev cia siab tensile. Nyob rau hauv kev xaiv ntawm impermeable zaj duab xis thickness nrog rau impermeable txaj nyob rau hauv qab ntawm niaj hnub reservoirs los yog reservoirs, lub impermeable zaj duab xis nqes hav thiab qis interface yuav tsum tau txiav txim siab dais unbalanced kev sib txhuam, uas ua rau tensile kev nyuaj siab nyob rau hauv lub geomembrane. Xav txog lub reservoir dej siab, yog hais tias cov dej qhov tob yog li 2m, siv tau 0.75mm los yog ntau tshaj 0.75mm geomemetic seepage tiv thaiv; Yog tias qhov dej tob ntawm lub reservoir yog li 4m, koj tuaj yeem siv 1.0mm lossis ntau dua 1.0mm geomemetic anti-seepage; Yog hais tias cov dej tob ntawm lub reservoir yog li 8m, 1.2mm los yog ntau tshaj geomembrane yuav tsum tau siv los tiv thaiv seepage. Tshwj xeeb reservoir impermeable geomembrane thickness yuav tsum tau txiav txim raws li qhov tseeb.
Txoj kev tsim kho ntawm lub pas dej geomembrane: tom qab khawb lub pas dej, lub geomembrane yog nteg, hauv qab tuaj yeem rov qab nrog cov av, sab saum toj ntawm txoj kab nqes yuav tsum tau anched, thiab qhov dav ntawm lub geomembrane tuaj yeem welded los yog glued rau pob tw. Pas dej geomembrane xyaum; Cov ntsiab lus tseem ceeb yog tuav ntawm ntug thiab cov ces kaum, thiab anched. Cov cuab yeej siv yog ob lub tsheb ciav hlau vuam tshuab, ib lub tsheb ciav hlau vuam tshuab, cua kub vuam phom.
