Geomembrane yog cov khoom siv tshwj xeeb siv rau engineering waterproofing, anti-seepage, anti-corrosion, thiab anti-corrosion, feem ntau yog ua los ntawm cov ntaub ntawv siab polymer xws li polyethylene thiab polypropylene. Nws muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, tiv thaiv kev laus, tiv thaiv ultraviolet, acid thiab alkali tsis kam, thiab yog siv dav hauv kev tsim vaj tsev engineering, kev tiv thaiv ib puag ncig, dej txuag engineering thiab lwm yam haujlwm.
Daim ntawv thov ntau yam ntawm geotextile daim nyias nyias yog dav heev, xws li engineering foundation anti-seepage, hydraulic engineering infiltration poob tswj, kua infiltration tswj nyob rau hauv landfill sites, qhov, hauv qab daus thiab subway engineering anti-seepage, thiab lwm yam.
Geomembranes yog tsim los ntawm cov ntaub ntawv polymer thiab tau txais kev kho tshwj xeeb, uas muaj kev tiv thaiv corrosion zoo thiab permeability tsis kam. Lawv tuaj yeem txo qhov tshwm sim ntawm kev puas tsuaj rau cov txheej txheem dej tsis zoo thiab ua kom lub neej ua haujlwm ntev ntawm qhov project.
Txoj kev tsim kho ntawm Geomembrane
Geomembrane yog ib zaj duab xis nyias siv rau kev tiv thaiv av, uas tuaj yeem tiv thaiv cov av poob thiab infiltration. Nws txoj kev tsim kho feem ntau suav nrog cov kauj ruam hauv qab no:
1. Kev npaj ua haujlwm: Ua ntej kev tsim kho, nws yog ib qho tsim nyog yuav tsum tau ntxuav qhov chaw kom ntseeg tau tias qhov chaw tiaj tus, tsis muaj cov khib nyiab thiab khib nyiab. Nyob rau tib lub sijhawm, qhov loj ntawm thaj av yuav tsum tau ntsuas los txiav txim siab thaj tsam ntawm geomembrane.
2. Tso zaj duab xis: nthuav tawm cov zaj duab xis geotextile thiab nteg nws ncaj nraim rau hauv av los xyuas seb puas muaj kev puas tsuaj lossis qhov khoob. Tom qab ntawd, ruaj khov kho cov geomembrane rau hauv av, uas tuaj yeem kho tau siv cov ntsia hlau ntsia hlau lossis cov hnab xuab zeb.
3. Trimming npoo: Tom qab tso, nws yog ib qho tsim nyog yuav tsum tau txiav cov npoo ntawm geotextile kom ntseeg tau tias nws yog nruj nreem khi rau hauv av thiab tiv thaiv infiltration.
4. Soil filling: Sau cov av nyob rau hauv lub geomembrane, saib xyuas kom tsis txhob overcompression thiab tswj cov av aeration thiab permeability.
5. Anchor ntug: Tom qab sau cov av, nws yog ib qho tsim nyog yuav tsum tau thauj cov ntug ntawm cov geotextile dua kom ntseeg tau tias nws yog nruj nreem khi rau hauv av thiab tiv thaiv kom tsis txhob tawm.
6. Kev ntsuam xyuas thiab kev saib xyuas: Tom qab kev tsim kho tiav, yuav tsum tau kuaj xyuas kom paub tseeb tias cov geotextile membrane tsis xau. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas thiab tswj cov geomembrane, thiab yog tias muaj kev puas tsuaj, kho lossis hloov nws raws sijhawm.
Thaum lub sij hawm tsim kho, yuav tsum tau them nyiaj rau kev nyab xeeb thiab ib puag ncig teeb meem kom tsis txhob muaj kev puas tsuaj rau ib puag ncig thiab kev raug mob ntawm tus kheej. Nyob rau tib lub sijhawm, nws yuav tsum xaiv cov ntaub ntawv geotextile tsim nyog raws li cov av sib txawv thiab ib puag ncig.
