Hauv cov haujlwm tswj kev ntws dej - xws li cov uas muaj cov qauv hauv av, cov pas dej cuav, thiab cov chaw pov tseg - yuav ua li cas thiaj daws tau qhov teeb meem ntawm kev xau dej kom zoo thiab ruaj khov? Ua ib lub chaw tsim khoom tshwj xeeb hauv kev lag luam geosynthetics, Shandong Hongyue Environmental Engineering Co., Ltd. (tom qab no hu ua "Hongyue Environmental") tau siv nws cov kev txawj ntse hauv Geosynthetic Clay Liners (GCLs) los tsim cov txheej txheem kev tsim kho uas muaj kev tshawb fawb thiab tus qauv. Los ntawm plaub kauj ruam tseem ceeb - "kev npaj qib av, kev teeb tsa kev tshawb fawb, kev sib tshooj meej, thiab kev rov qab ua kom tiav raws sijhawm" - cov txheej txheem no siv tag nrho cov txiaj ntsig tshwj xeeb ntawm GCLs, tshwj xeeb tshaj yog lawv lub peev xwm "o thaum kov dej thiab kho tus kheej," yog li tsim kom muaj cov dej tsis nkag tau rau ntau yam haujlwm engineering.
Kauj Ruam Ib: Kev Npaj Subgrade Kom Zoo - Tso Lub Hauv Paus Kom du thiab Ruaj Khob
Qhov zoo ntawm cov khoom siv hauv qab txiav txim siab ncaj qha rau qhov ua tau zoo ntawm kev teeb tsa GCL. Pab pawg kws tshaj lij ntawm Hongyue Environmental hais tias qhov chaw ntawm cov khoom siv hauv qab yuav tsum tau npaj ua ntej kev tsim kho. Ua ntej, cov khoom siv hauv qab yuav tsum tau compacted thiab leveled; tshwj xeeb, qhov sib piv ntawm qhov tiaj tiaj (txhais tau tias yog qhov sib piv ntawm qhov tob tshaj plaws ntawm txhua qhov kev nyuaj siab rau nws qhov tsawg kawg nkaus) yuav tsum tsis pub tshaj 1: 6, thiab txhua qhov kev hloov pauv yuav tsum maj mam, txwv tsis pub muaj cov yam ntxwv ntse xws li cov ces kaum sab xis. Qhov thib ob, qhov chaw ntawm cov khoom siv hauv qab yuav tsum tau khaws cia kom huv si, nrog rau kev tshem tawm tag nrho cov khib nyiab ntse - suav nrog cov hauv paus nyom, cov xuab zeb loj dua 10 hli hauv txoj kab uas hla, thiab cov khoom seem cib - kom tiv thaiv cov ntaub sab nraud ntawm GCL kom tsis txhob raug tho thaum lub sijhawm teeb tsa. Ntxiv mus, thaum GCLs tuaj yeem ntsia tau rau ntawm cov khoom siv hauv qab uas ntub dej, kev sib sau ua ke ntawm cov dej sawv ntawm qhov chaw raug txwv tsis pub ua; thaum muaj dej ntws tsis tuaj yeem tswj tau, yuav tsum tau ua cov kev ntsuas hloov pauv ib ntus ua ntej kom ntseeg tau tias qhov chaw ua haujlwm tseem nyob hauv qhov zoo tshaj plaws.
Kauj Ruam Ob: Kev Teeb Tsa thiab Kev Txuas Nruj - Xyuas Kom Ruaj Khoov thiab Ruaj Ntseg
Thaum lub sijhawm teeb tsa, Hongyue Environmental pom zoo kom txiav cov GCLs ua ntej raws li qhov loj ntawm qhov project; cov liners yuav raug muab tso rau hauv kab rov tav lossis kab rov tav. Thaum lub sijhawm tsim kho, GCL raug dov tiaj tiaj rau ntawm qhov chaw npaj, feem ntau muab tso rau ntawm cov ntaub woven uas tig mus rau hauv av thiab cov txheej geotextile uas tsis yog woven tig mus rau saum toj. Txhawm rau kom ntseeg tau tias muaj kev sib cuag ze ntawm GCL thiab qhov chaw teeb tsa, cov pins tshwj xeeb thiab cov washers yuav tsum tau siv rau kev ruaj ntseg; ntxiv rau, cov npoo ntawm lub liner yuav tsum tau hnyav nrog cov hnab xuab zeb kom tiv thaiv kev hloov pauv los ntawm cua. Cov kws tshaj lij hais tias yuav tsum ceev faj heev thaum lub sijhawm teeb tsa. Nws raug txwv tsis pub rau cov tshuab hnyav tsav ncaj qha hla qhov chaw ntawm daim pam. Cov neeg ua haujlwm taug kev ntawm cov khoom yuav tsum hnav khau tiaj tiaj kom tiv thaiv cov khoom ntse los ntawm kev tho qhov sab hauv daim nyias nyias (hauv cov ntaub thaiv dej tsis muaj membrane-laminated) lossis ua rau cov txheej geotextile sab nraud puas tsuaj, ib qho ntawm cov no yuav cuam tshuam kev faib tawm ntawm bentonite.
Kauj Ruam 3: Kev Kho Mob Sib Tov Zoo—Tsim Ib Txheej Uas Tsis Ncua Mus Ib Txhis
Kev kho pob qij txha yog qhov tseem ceeb uas txiav txim siab seb tag nrho lub kaw lus tsis pub dej nkag tau zoo lossis tsis ua tiav. Cov lus qhia txog kev tsim kho ntawm Hongyue Environmental hais kom qhov dav ntawm cov pam vov uas nyob ib sab yuav tsum tswj kom tsawg kawg yog 25 cm txog 30 cm. Hauv thaj chaw uas sib tshooj, yuav tsum siv cov hmoov bentonite qhuav tshwj xeeb (lossis bentonite paste) uas lub tuam txhab muab - sib npaug. Tus nqi siv feem ntau yog tswj hwm ntawm kwv yees li 0.4 kg / m² kom ntseeg tau tias, thaum sib cuag nrog dej, qhov sib koom ua ib txheej tsis pub dej nkag, ntom ntom, zoo li gel. Txhawm rau kom kaw cov overlaps ntxiv, daim ntawv thov hmoov tuaj yeem ntxiv nrog daim kab xev tsis pub dej nkag, kom ntseeg tau tias txhua yam meej meej tsis ua haujlwm thiab tsim kom muaj kev sib khi tsis pub dej nkag.
Kauj Ruam 4: Kev Rov Qab Ua Dua Txheej Raws Sijhawm - Muab Kev Tiv Thaiv Mus Ntev
Thaum cov pam vov uas tsis pub dej nkag tau lawm, cov txheej txheem tsim txheej tiv thaiv lossis rov qab los yuav tsum pib sai li sai tau. Qhov no tiv thaiv cov pam vov kom tsis txhob qhuav thiab poob lawv qhov ua tau zoo vim raug cua ntev, lossis los ntawm kev o ua ntej yog tias raug nag los. Hongyue Environmental muab qhov tseem ceeb rau cov kev cai zoo rau cov av rov qab los: cov av yuav tsum tau tshuaj xyuas kom tsis txhob muaj cov khoom tawv - xws li cov xuab zeb lossis cov cib - uas muaj qhov loj me tshaj 10 hli. Thaum lub sijhawm tsim kho, cov av huv lossis cov xuab zeb zoo yuav tsum tau siv rau kev rov qab los thiab kev sib zog; txhua txheej tuab yuav tsum tau tswj hwm hauv qhov ntau ntawm 30 cm txog 50 cm, thiab qhov ceev ntawm kev sib zog yuav tsum ncav cuag tsawg kawg 85%. Cov txheej txheem no tsis yog tsuas yog tiv thaiv cov pam vov uas tsis pub dej nkag los ntawm kev puas tsuaj sab nraud xwb tab sis kuj siv lub siab los ntawm cov av los txhim kho qhov ruaj khov ntawm cov txheej tsis pub dej nkag.
Siv cov txheej txheem "Plaub Kauj Ruam Tsim Kho," Shandong Hongyue Environmental cov pam bentonite tiv thaiv dej tau ua pov thawj tag nrho lawv cov txiaj ntsig tseem ceeb: kev tiv taus siab rau hydrostatic siab (tshaj 1.0 MPa), muaj peev xwm kho tus kheej zoo (muaj peev xwm kho cov kab nrib pleb txog li 2 hli), nrog rau kev tiv thaiv kev laus zoo heev thiab cov khoom zoo rau ib puag ncig. Txij li kev tsim khoom siv mus rau kev taw qhia kev siv tshuab hauv tsev, Hongyue Environmental Protection cog lus tias yuav muab cov neeg siv khoom nrog cov kev daws teeb meem tiv thaiv kev ntws, siv kev txawj ntse thiab cov txheej txheem nruj kom ntseeg tau tias txhua qhov project tseem tsis muaj dej nkag.
