(1) Txhawm rau txhim kho lub nraub qaum ntawm cov phab ntsa tuav lossis thauj tog rau nkoj lub ntsej muag ntawm cov phab ntsa tuav.Ua cov phab ntsa tuav los yog abutments.
(2) Txhim kho txoj kev hloov pauv hloov pauv, kho cov kab nrib pleb ntawm txoj kev thiab tiv thaiv kev cuam tshuam ntawm qhov chaw ntawm txoj kev.
(4) Cov txheej txheem kev sib cais ntawm ballast thiab roadbed lossis ntawm roadbed thiab cov av mos.
(6) Cov txheej lim dej ntawm sab saud ntawm qhov pib tshauv cia lub pas dej lossis lub pas dej tailings, thiab cov txheej lim dej ntawm cov kav dej hauv qhov rov qab ntawm phab ntsa tuav.
(7) Cov txheej lim nyob ib ncig ntawm cov kav dej los yog gravel kwj dej.
(8) Cov lim dej ntawm qhov dej, qhov dej nyem lossis oblique siab kav hauv hydraulic engineering.
(10) Vertical los yog kab rov tav ntws nyob rau hauv lub ntiaj teb dam, faus rau hauv av kom dissipate lub pore dej siab.
(11) Dej ntws tom qab impervious geomembrane lossis hauv qab pob zeb npog hauv lub ntiaj teb dams lossis embankments.
Filament Tsis-woven Geotextile installation:
1, nrog phau ntawv dov nruab, filament tsis woven geotextile nto yuav tsum tau theem tawm, thiab tsim nyog deformation nyiaj.
2. Lub installation ntawm Filament Non woven Geotextile los yog luv fiber non woven geotextile feem ntau yog siv ntau txoj kev ntawm kev sib koom tes, suture thiab vuam.Qhov dav ntawm suture thiab vuam feem ntau yog ntau tshaj 0.1m, thiab lub puab tsaig dav feem ntau yog ntau tshaj 0.2m.Geotextiles uas yuav raug rau lub sij hawm ntev yuav tsum tau welded los yog sewn ua ke.
3. Geotextile suture:
Tag nrho cov stitches yuav tsum tsis tu ncua (piv txwv li, tsis tso cai rau stitches).Filament Non woven Geotextile yuav tsum sib tshooj tsawg kawg 150mm ua ntej sib tshooj.Qhov tsawg kawg nkaus stitch nrug ntawm ntug (qhov nthuav tawm ntawm cov khoom) yuav tsum yog tsawg kawg yog 25 hli.
Filament Non woven Geotextile pob qij txha uas tau sewn feem ntau muaj xws li 1 kab ntawm cable xauv saw plooj txoj kev.Cov xov siv rau suture yuav tsum yog cov khoom siv nrog qhov tsawg kawg nkaus ntawm ntau tshaj 60N thiab yuav tsum muaj tib yam lossis ntau dua rau cov tshuaj tiv thaiv corrosion thiab ultraviolet hluav taws xob raws li geotextile.
Ib qho "koob leakage" ntawm geotextile yuav tsum tau rov sewn qhov twg nws cuam tshuam.
Kev ntsuas tsim nyog yuav tsum tau coj los tiv thaiv cov av, cov khoom me me lossis cov khoom txawv teb chaws los ntawm kev nkag mus rau geotextile txheej tom qab kev teeb tsa.
Lub puab tsaig ntawm daim ntaub tuaj yeem muab faib ua cov ceg tawv sib koom ua ke, sib koom ua ke los yog vuam raws li qhov chaw nyob thiab siv ua haujlwm.
4. Nyob rau hauv kev tsim kho, HDPE geomembrane saum toj no geotextile yuav tsum overlapped lawm, thiab HDPE geomembrane nyob rau hauv lub sab sauv txheej, lub filament tsis woven geotextile yuav tsum seamed los yog welded los ntawm cov cua kub.Cov cua kub welding yog txoj kev nyiam kev sib txuas ntawm filament geotextile, uas yog, kev sib txuas ntawm ob daim ntaub nrog cov phom cua kub yog tam sim ntawd rhuab ntawm qhov kub siab, yog li ntawd ib feem ntawm nws mus txog lub xeev melting, thiab tam sim ntawd siv ib qho kev quab yuam sab nraud. ua kom nws ruaj khov ua ke.Nyob rau hauv ntub dej (los nag thiab daus) huab cua tsis tuaj yeem kub adhesion kev twb kev txuas, geotextile yuav tsum tau txais lwm txoj kev sib txuas txoj kev, uas yog, tshwj xeeb tshuab xaws rau ob chav suture kev twb kev txuas, thiab siv cov tshuaj tiv thaiv ultraviolet suture kab.
Qhov tsawg kawg nkaus dav ntawm suture yog 10cm, qhov tsawg kawg nkaus qhov dav ntawm ntuj ceg yog 20cm, thiab qhov tsawg kawg nkaus dav ntawm cov cua kub vuam yog 20cm.
5. Rau cov hlua khi, cov khoom siv zoo ib yam li geotextile yuav tsum tau siv, thiab cov kab suture yuav tsum tau ua los ntawm cov ntaub ntawv uas muaj zog tiv thaiv cov tshuaj lom neeg puas tsuaj thiab ultraviolet irradiation.
6. Geomembrane yuav tsum tau muab tso rau tom qab geotextile tso thiab pom zoo los ntawm tus kws saib xyuas ntawm qhov chaw.
Cov kev cai yooj yim rau Filament Nonwoven Geotextile nteg:
1. Kev sib koom ua ke yuav tsum hla txoj kab nqes hav;Qhov twg muaj qhov sib npaug lossis muaj peev xwm ntxhov siab nrog tus taw ntawm txoj kab nqes, kab rov tav sib txuas yuav tsum siab dua 1.5m.
2. Ntawm txoj kab nqes, thauj tog rau nkoj ib kawg ntawm Filament Non woven Geotextile, thiab tom qab ntawd nteg cov khoom yob rau ntawm txoj kab nqes kom ntseeg tau tias cov geotextile nyob nruj.
3. Tag nrho cov Filament Non-woven Geotextile yuav tsum tau nias nrog cov hnab xuab zeb, uas yuav tsum tau siv thaum lub sij hawm nteg thiab khaws cia rau saum txheej ntawm cov ntaub ntawv.
