Nrog rau kev loj hlob ntawm peb lub teb chaws kev lag luam thiab kev txhim kho ntawm cov qauv kev ua neej, cov geotextile membranes tau pom tias muaj kev siv dav dua. Txawm li cas los xij, txawm tias rau tib hom geotextile membrane, lub neej ua haujlwm tuaj yeem sib txawv ntau nyob ntawm qhov chaw tshwj xeeb thiab cov xwm txheej ua haujlwm. Yog li, peb yuav siv cov geotextile membranes kom zoo li cas kom ua rau lawv lub neej ua haujlwm ntev tshaj plaws? Niaj hnub no, cia peb tshawb nrhiav cov lus ceeb toom tseem ceeb uas yuav tsum tau ua thaum siv cov ntaub ntawv no.
Thaum siv cov geotextile membranes, nws raug pom zoo kom txo qhov kev raug lub teeb. Yog tias daim nyias nyias tuaj yeem tiv thaiv tau lub teeb thaum lub sijhawm ua haujlwm, qhov no muab kev lees paub zoo rau kev txuas ntxiv nws lub neej ntev.
Thaum lub sijhawm teeb tsa, daim ntaub thaiv yuav tsum tau muab tso rau qhov nruab nrab, kom muaj qee qhov ntug ntawm kev nthuav dav thiab kev sib cog lus; txwv tsis pub ncab ntau dhau. Kev hloov pauv kub thiab av poob qis tuaj yeem ua rau cov ntaub thaiv tau tawg; kev tso daim ntaub thaiv nrog qee qhov kev sib cog lus zoo txo cov kev pheej hmoo no. Kev teeb tsa yuav tsum mus rau hauv qab ntawm qhov nqes hav - los ntawm sab saud mus rau hauv qab - kom txo cov xov sib tshuam. Qhov dav ntawm cov ntawv sib tshooj ntawm cov ntawv sib tshooj yuav tsum ua tau raws li cov qauv tsim: cov ntaub sib tshooj vuam yuav tsum tsis pub tsawg dua 10 cm dav, thaum cov ntaub sib tshooj sib txuas yuav tsum tsis pub tsawg dua 15 cm dav.
Cov neeg ua haujlwm tsim kho yuav tsum hnav khau mos mos thaum ua haujlwm; taug kev saum daim nyias nyias hauv khau tawv lossis khau uas muaj cov ntsia hlau pom yog txwv tsis pub ua. Cov cuab yeej tsim kho yuav tsum tau ua tib zoo tuav kom tsis txhob poob hnyav. Cov tshuab hnyav thiab tsheb raug txwv tsis pub tsav tsheb ncaj qha hla daim nyias nyias geotextile; yog tias cov haujlwm no tsim nyog, cov khaubncaws sab nraud povtseg tiv thaiv ib ntus - xws li cov ntoo lossis cov hnab xuab zeb - yuav tsum tau muab tso rau hauv av ua ntej. Ntxiv mus, cov huab cua thaum lub sijhawm tsim kho yuav tsum tau saib xyuas nruj me ntsis. Kev teeb tsa thiab kev vuam raug txwv tsis pub ua thaum huab cua los nag lossis pos huab, thaum cua tshaj Force 5, lossis thaum qhov kub thiab txias poob qis dua 5 ° C, kom tiv thaiv daim nyias nyias kom tsis txhob raug cua lossis kom ntseeg tau tias qhov zoo ntawm kev vuam ua tau raws li cov qauv xav tau.
Thaum twg qhov project engineering tau pib ua haujlwm lawm, yuav tsum muaj ib txoj kev los tshuaj xyuas txhua lub sijhawm. Yuav tsum tau ua tib zoo saib xyuas cov chaw tseem ceeb xws li cov vuam sib txuas, cov chaw hloov pauv ntawm qhov nqes hav, thiab cov cheeb tsam uas muaj dej sib sau ua ke, kom paub seb puas muaj cov cim qhia tias puas tsuaj, tawg, tawg vim yog kev sib tsoo, lossis nkag mus rau hauv cov hauv paus. Hauv thaj chaw uas dej tsis nkag tau, cov haujlwm xws li kev tsav pawg, kev khawb, lossis kev rub cov khoom tawv raug txwv tsis pub ua kom tiv thaiv kev puas tsuaj los ntawm tib neeg.
Rau cov ntawv thov tshwj xeeb—xws li cov chaw pov tseg lossis cov pas dej tshuaj lom neeg—nws yog ib qho tseem ceeb uas yuav tsum xaiv cov ntaub geotextile uas tsim tshwj xeeb rau kev tiv thaiv corrosion siab thiab cov khoom tiv thaiv kev laus, thiab ua qhov kev sim ua haujlwm tsis tu ncua ntawm cov khoom siv membrane. Txhua qhov kev puas tsuaj me me uas pom yuav tsum tau kho tam sim ntawd kom tiv thaiv qhov xau los ntawm kev nthuav dav thiab kom ntseeg tau tias lub kaw lus impermeable ruaj khov thiab kev ncaj ncees mus sij hawm ntev. Cov kws tshaj lij hauv kev lag luam hais tias, thaum nws los txog rau kev siv geomembranes, tsis muaj qhov me me dhau; txhua qhov ib qho cuam tshuam ncaj qha rau ob qho tib si qhov zoo ntawm qhov project thiab kev nyab xeeb ib puag ncig. Cov neeg cog lus thiab cov neeg siv kawg yuav tsum ua raws li cov qauv thiab cov qauv tsim, siv cov kev tswj hwm thoob plaws hauv tag nrho cov txheej txheem, txhawm rau kom siv tau qhov tsis pub dhau ntawm geomembranes thiab txhawb nqa qhov project "impermeability lifeline."
