Geotextile feem ntau yog siv los hloov cov khoom siv granular ib txwm los tsim cov lim dej rov qab thiab lub cev ntws tawm.Piv nrog rau cov tsoos inverted lim thiab lub cev ntws, nws muaj cov yam ntxwv ntawm lub teeb yuag, zoo tag nrho txuas ntxiv, kev tsim kho yooj yim, siab tensile lub zog, corrosion kuj, zoo microbial yaig kuj, mos zoo nkauj, zoo bonding nrog av cov ntaub ntawv, siab durability thiab huab cua. Kev tiv thaiv hauv dej los yog hauv av, thiab siv tau zoo heev Thiab cov geotextile kuj ua tau raws li cov xwm txheej ntawm cov ntaub ntawv lim dej dav dav: 1 Kev txuag av: tiv thaiv kev poob ntawm cov ntaub ntawv tiv thaiv av, ua rau seepage deformation, 2 Dej permeability: xyuas kom cov dej ntws zoo ntawm seepage. dej, 3 Anti thaiv cov cuab yeej: xyuas kom meej tias nws yuav tsis raug thaiv los ntawm cov av zoo.

Lub geotextile yuav tsum tau muab nrog daim ntawv pov thawj khoom zoo thaum siv, thiab cov ntsuas lub cev yuav tsum tau sim: huab hwm coj ib cheeb tsam, thickness, sib npaug aperture, thiab lwm yam Mechanical indexes: tensile zog, kua muag zog, tuav lub zog, bursting zog, tawg. Lub zog, kev sib txhuam lub zog ntawm cov khoom siv hauv av sib cuam tshuam, thiab lwm yam Hydraulic ntsuas: ntsug permeability coefficient, dav hlau permeability coefficient, gradient piv, thiab lwm yam Durability: kev laus tsis kam, tshuaj tiv thaiv corrosion Qhov kev ntsuam xyuas yuav tsum tau ua los ntawm lub tuam txhab kev soj ntsuam zoo.Thaum lub sij hawm xeem, cov khoom soj ntsuam cuam tshuam tuaj yeem raug ntxiv lossis tshem tawm raws li qhov project xav tau thiab kev tsim kho tshwj xeeb, thiab yuav tsum tau tshaj tawm tsab ntawv tshaj tawm kev tshuaj xyuas.
Thaum lub sij hawm tso geotextile, qhov chaw sib cuag yuav tsum tau khaws cia kom tiaj tus yam tsis muaj qhov tsis sib xws, pob zeb, cov hauv paus ntoo lossis lwm cov khib nyiab uas yuav ua rau cov geotextile puas tsuaj Thaum tso cov geotextile, nws yuav tsum tsis txhob nruj heev kom tsis txhob muaj ntau dhau deformation thiab tearing ntawm geotextile thaum lub sij hawm tso geotextile. kev tsim kho.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tswj kom muaj kev nruj nruj.Yog tias tsim nyog, geotextile tuaj yeem ua rau cov geotextile muaj cov folds sib xws Thaum tso geotextile: thawj zaug nteg cov geotextile los ntawm cov dej ntws ntawm cov ntaub qhwv nqes mus, thiab nteg nws los ntawm thaiv raws li tus lej.Qhov sib tshooj dav ntawm cov blocks yog 1m.Thaum nteg lub taub hau puag ncig, vim yog qhov nqaim thiab qis qis, kev saib xyuas tshwj xeeb yuav tsum tau them rau kev tso, kev tsim kho kom zoo yuav tsum tau ua, thiab qhov sib tshooj dav ntawm cov blocks yuav tsum tau ua kom ntseeg tau tias kev sib koom ua ke ntawm geotextile thiab dam foundation thiab lub txhab nyiaj. Yuav tsum tau ua kom zoo Thaum tso, peb yuav tsum tswj kev txuas ntxiv thiab tsis nco qab tso tom qab geotextile tso, nws tsis tuaj yeem raug rau lub hnub vim tias cov geotextile yog ua los ntawm cov khoom siv fiber ntau cov khoom siv hluav taws xob tshav ntuj yuav ua rau lub zog puas tsuaj, yog li kev tiv thaiv yuav tsum tau ua. coj.
Peb cov kev tiv thaiv hauv kev tsim kho geotextile yog: npog cov paved geotextile nrog straw, uas ua kom ntseeg tau tias geotextile yuav tsis raug rau lub hnub, thiab tseem ua lub luag haujlwm zoo dua los tiv thaiv geotextile rau tom qab siv pob zeb txawm tias cov txheej txheem tiv thaiv ntawm straw mulch. yog ntxiv thiab stonework kev tsim kho yog nqa tawm ntawm geotextile, geotextile yuav tsum tau ua tib zoo tiv thaiv Tsis tas li ntawd, txoj kev tsim kho zoo tshaj plaws yuav tsum raug xaiv rau txoj kev tsim kho ntawm stonework Peb txoj kev tsim kho yog tias, vim qhov siab ntawm kev siv tshuab ntawm kev tsim kho. , lub pob zeb yog thauj los ntawm cov tsheb thauj khoom pov tseg.Thaum lub pob zeb tshem tawm, ib tus neeg tshwj xeeb raug xaiv los tswj lub tsheb kom thauj cov pob zeb, thiab lub pob zeb raug tshem tawm sab nraum lub hauv paus pob zeb trough Cov phau ntawv hloov lub tank yuav tsum tau ua tib zoo saib xyuas kom tsis txhob ua rau cov geotextile ua ntej, kab tag nrho cov pob zeb raws. hauv qab ntawm trench rau 0.5m.Lub sijhawm no, ntau tus neeg tuaj yeem pov pob zeb raws li pob zeb nto ntawm qhov thaiv kom zoo.Tom qab lub trench puv lawm, manually hloov lub pob zeb raws txoj kab nqes sab hauv ntawm lub ntiaj teb dam foundation.Qhov dav ntawm lub pob zeb yog tib yam li qhov xav tau los ntawm kev tsim.Lub pob zeb yuav tsum sib npaug zos thaum lub pob zeb pov tseg.Lub pob zeb nto ntawm qhov thaiv nyob rau hauv txoj kab nqes sab hauv yuav tsum tsis txhob siab dhau Yog tias nws siab dhau lawm, nws tsis muaj kev nyab xeeb rau cov filament woven geotextile, thiab nws kuj tseem yuav swb, ua rau kev puas tsuaj rau geotextile yog li ntawd, yuav tsum tau them nyiaj tshwj xeeb. kom muaj kev nyab xeeb thaum lub sij hawm tsim kho Thaum lub pob zeb tiaj tus tau muab tso rau hauv txoj kab nqes sab hauv ntawm lub log tsheb mus rau 2m deb ntawm lub pas dej ua ke, cov pob zeb yuav tsum tau muab tso rau hauv txoj kab nqes sab hauv, thiab lub thickness yuav tsum tsis pub tsawg tshaj 0.5m.Cov pob zeb yuav tsum tau muab tshem tawm mus rau hauv lub pas dej ua ke, thiab cov pob zeb yuav tsum tau ua tib zoo muab pov tseg manually, thiab cov pob zeb yuav tsum tau leveled thaum muab pov mus txog rau thaum lawv leveled nrog rau saum lub ntiaj teb dam ces, raws li tus tsim txoj kab nqes, kab sab sauv. yuav tsum tau leveled kom ua tiav txoj kab nqes saum toj kawg nkaus.
① Cov txheej txheem tiv thaiv: nws yog txheej txheej sab nraud ntawm kev sib cuag nrog lub ntiaj teb sab nraud.Nws yog tsim los tiv thaiv kev cuam tshuam ntawm cov dej sab nraud los yog nthwv dej, huab cua thiab yaig, khov thiab ua rau lub nplhaib thiab tiv thaiv lub hnub ci ultraviolet.Lub thickness feem ntau yog 15-625px.
② Upper cushion: nws yog qhov hloov pauv ntawm txheej tiv thaiv thiab geomembrane.Txij li cov txheej txheem tiv thaiv feem ntau yog cov khoom loj ntawm cov ntaub ntawv ntxhib thiab yooj yim txav, yog tias nws ncaj qha tso rau ntawm geomembrane, nws yooj yim rau kev puas tsuaj rau geomembrane.Yog li ntawd, lub cushion qaum yuav tsum tau npaj kom zoo.Feem ntau, muaj cov khoom siv xuab zeb gravel, thiab lub thickness yuav tsum tsis pub tsawg tshaj 375px.
③ Geomembrane: nws yog lub ntsiab lus ntawm kev tiv thaiv seepage.Ntxiv nrog rau kev tiv thaiv kev ruaj ntseg seepage, nws yuav tsum muaj peev xwm tiv taus qee qhov kev tsim kho kev ntxhov siab thiab kev ntxhov siab los ntawm kev sib haum xeeb thaum siv.Yog li ntawd, kuj tseem muaj lub zog xav tau.Lub zog ntawm geomembrane yog ncaj qha ntsig txog nws cov tuab, uas tuaj yeem txiav txim siab los ntawm kev suav theoretical lossis kev paub txog engineering.
④ Lub cushion qis: pw hauv qab geomembrane, nws muaj ob txoj haujlwm: ib qho yog tshem tawm cov dej thiab roj hauv qab daim nyias nyias kom ruaj khov ntawm geomembrane;lwm qhov yog los tiv thaiv geomembrane los ntawm kev puas tsuaj ntawm cov txheej txheem txhawb nqa.
⑤ Cov txheej txheem txhawb nqa: geomembrane yog cov khoom siv tau yooj yim, uas yuav tsum tau muab tso rau ntawm txheej txheej txhawb nqa, uas tuaj yeem ua rau geomembrane kev nyuaj siab sib npaug.
