Kev kho txoj kev geotextiletxheej txheem tso
1. Kev khaws cia, kev thauj mus los thiab kev tuav cov geotextiles
Cov yob geotextile yuav tsum tau tiv thaiv kom tsis txhob puas ua ntej kev teeb tsa. Cov yob geotextile yuav tsum tau muab tso rau hauv qhov chaw uas tsis muaj dej sib sau ua ke, qhov siab ntawm pawg yuav tsum tsis pub tshaj plaub lub yob, thiab daim ntawv txheeb xyuas ntawm lub yob tuaj yeem pom. Cov yob geotextile yuav tsum tau npog nrog cov ntaub ntawv opaque kom tiv thaiv UV laus. Thaum lub sijhawm khaws cia, kev ncaj ncees ntawm daim ntawv lo thiab kev ncaj ncees ntawm cov ntaub ntawv yuav tsum tau khaws cia.
Cov geotextiles yuav tsum tau tiv thaiv kom tsis txhob puas thaum lub sijhawm thauj mus los, suav nrog kev thauj mus los ntawm qhov chaw khaws khoom mus rau qhov chaw ua haujlwm.
Cov ntaub geotextiles uas puas lawm yuav tsum tau kho. Cov ntaub geotextiles uas puas lawm hnyav heev yuav tsis siv tau. Cov ntaub geotextiles uas kov cov tshuaj reagents uas xau tsis pub siv rau hauv qhov project no.
2. Txoj kev tso geotextile:
Dov nws los ntawm tes; daim ntaub nto yuav tsum tiaj tus thiab qhov kev hloov pauv yuav tsum tau tso tseg raws li qhov tsim nyog.
Feem ntau, kev teeb tsa cov filament lossis cov geotextiles luv luv yog ua los ntawm kev sib koom ua ke, kev xaws thiab kev vuam. Qhov dav ntawm kev xaws thiab kev vuam feem ntau yog siab dua, thiab qhov dav ntawm kev sib tshooj feem ntau yog siab dua. Cov geotextiles uas yuav raug nthuav tawm ntev yuav tsum tau vuam lossis xaws.
Kev xaws ntawm geotextile
Txhua qhov kev xaws yuav tsum ua tas mus li (piv txwv li, tsis pub xaws). Cov Geotextiles yuav tsum sib tshooj tsawg kawg yog 150 hli ua ntej sib tshooj. Qhov nrug tsawg kawg yog 25 hli ntawm ntug ntawm cov khoom.
Cov xov ntawm cov geotextiles uas tau xaws zoo suav nrog ib txoj kab thiab txoj kev xaws saw hlau. Cov xov siv rau kev xaws yuav tsum yog cov khoom siv resin nrog qhov nruj tsawg kawg nkaus ntau dua 60 N thiab kev tiv thaiv tshuaj lom neeg thiab UV sib npaug rau lossis ntau dua li ntawm geotextile.
Txhua yam "leakage needle" ntawm qhov sewed geotextile yuav tsum tau rov sewed rau thaj chaw cuam tshuam.
Yuav tsum tau ua cov kev ntsuas sib xws kom tiv thaiv av, cov khoom me me lossis cov khoom txawv teb chaws nkag mus rau hauv geotextile tom qab kev teeb tsa.
Geotextilecov pob qij txha hauv caug tuaj yeem muab faib ua cov pob qij txha hauv caug ntuj, cov seams lossis welds nyob ntawm thaj av thiab kev ua haujlwm.
Qhov sib txawv ntawm anti-seepage geotextile thiab seepage geotextile
Thaum cov dej ntws los ntawm cov av zoo mus rau cov av ntxhib, cov geotextile nrog cov pa roj zoo thiab cov dej permeability yog koob nrog polyester staple fiber kom dhau dej, nqa cov av me me, xuab zeb zoo thiab pebbles, thiab tswj cov geolayer thiab dej. Kev ruaj khov engineering.
Lub geotextile tiv thaiv kev seepage tseem ceeb yog ib hom polymer tshuaj lom neeg yooj ywm, uas muaj cov yam ntxwv ntawm qhov me me, siab elongation, muaj zog ntawm deformation, corrosion tsis kam, tsis kub tsis kam thiab zoo frost tsis kam.
Lub tshuab tseem ceeb yog tias qhov xau ntawm lub pas dej av-pob zeb raug txiav los ntawm qhov tsis muaj dej ntawm cov yas zaj duab xis. Cov yas zaj duab xis tau txais dej siab, thiab nrog kev nce ntawm lub zog tensile thiab elongation, nws tuaj yeem siv rau qhov deformation ntawm lub pas dej; nws kuj yog ib qho polymer. Cov tshuaj fiber luv luv, uas ua tiav lub zog tensile siab dua thiab elongation los ntawm kev xuas koob lossis cua sov sealing, tsis yog tsuas yog ua rau cov yas ntau ntxiv tom qab sib xyaw.
Vim tias qhov chaw ntawm cov geotextile nonwoven yog ntxhib, lub zog tensile thiab puncture tsis kam ntawm cov ntaub ntawv zaj duab xis nce qhov sib txhuam coefficient ntawm qhov kov nto, uas yog qhov zoo rau kev ruaj khov ntawm cov geomembrane sib xyaw thiab cov txheej tiv thaiv. Ua ke nrog kev tiv thaiv zoo rau cov kab mob corrosion thiab chemistry, tsis ntshai acid, alkali, ntsev corrosion.
Kev Ua Haujlwm: lub zog tawg siab, txog li 20KN / m, tiv thaiv kev nkag thiab tiv thaiv corrosion. Nws tuaj yeem siv rau hauv kev txuag dej, pas dej, kev tsim kho txoj kev loj, tshav dav hlau, kev tsim kho, kev tiv thaiv ib puag ncig thiab lwm yam haujlwm, thiab tuaj yeem ua lub luag haujlwm ntawm kev lim dej, kev ntws dej, kev cais tawm, kev tiv thaiv thiab kev txhawb nqa.
