Raws li cov khoom siv engineering uas tuaj yeem txhim kho qhov project zoo, txhim kho kev tsim kho, txo cov nqi tsim kho thiab ncua lub sijhawm tu, geotextiles tau siv dav hauv ntau yam xws li kev loj, kev tsheb ciav hlau, kev txuag dej thiab chaw nres nkoj, tab sis geotextiles tau muab tso thiab sib tshooj. paub meej, koj puas paub?
1. Geotextiles raug pom zoo kom txhim kho mechanically lossis manually nteg. Thaum tso, yuav tsum tau saib xyuas kom ua kom lub ntsej muag ntxhib ntawm lub ntsej muag, thiab tom qab ntawd kho ib qho kawg nrog lub fixer, thiab nruj nrog cov tshuab lossis cov neeg ua haujlwm. layout. Lub fixer muaj xws li ib tug fixation ntsia thawv thiab ib tug fixation hlau ntawv. Cov ntsia hlau los yog tua cov ntsia hlau yuav tsum tau siv los kho cov ntsia hlau, nrog qhov ntev ntawm 8 mus rau 10 cm; hlau strips nrog lub thickness ntawm 1 hli thiab dav ntawm 3 hli tuaj yeem siv rau cov ntawv hlau ruaj khov.
2. Lub geotextile yog lapped kab rov tav li ntawm 4-5cm. Raws li cov kev taw qhia paving, nias lub rear kawg nyob rau hauv pem hauv ntej kawg, cement nws nrog kub asphalt los yog emulsified asphalt, thiab kho nws nrog ib tug fixer; lub caj dab ntev kuj yog hais txog 4-5cm, tuaj yeem ncaj qha qhuav nrog cov roj khi. Yog tias lub puab tsaig dav dav, lub interlayer ntawm lub puab tsaig yuav ua tuab dua, thiab lub zog sib txuas ntawm cov txheej txheej saum npoo thiab lub hauv paus txheej yuav tsis muaj zog, uas yuav yooj yim ua rau muaj kev cuam tshuam tsis zoo xws li bulging, detachment, thiab hloov chaw. txheej txheej. Yog li ntawd, qhov chaw uas dav dhau yuav tsum tau txiav tawm.
3. Lub geotextile yuav tsum tau muab tso rau hauv txoj kab ncaj nraim kom ntau li ntau tau. Thaum nws yog lub sij hawm tig, cov ntaub khoov yog txiav qhib, nteg thiab txau nrog tack coat rau kua nplaum. Qhov wrinkling ntawm cov ntaub yuav tsum zam kom ntau li ntau tau. Yog hais tias muaj wrinkles thaum lub sij hawm tso (thaum lub qhov siab qhov siab yog> 2cm), qhov no yuav tsum tau txiav ib feem ntawm lub wrinkle, thiab ces overlapped nyob rau hauv lub nteg cov kev taw qhia thiab muab tso rau nrog nplaum txheej roj.
4. Thaum cov geotextile tso, tom qab txau cov roj asphalt nplaum ob zaug thiab txias rau li 2 teev, qhov tsim nyog ntawm cov xuab zeb daj zoo yuav tsum muab pov tseg rau lub sijhawm kom tsis txhob lub tsheb hla ntawm geotextile, daim ntaub yuav raug tshem tawm lossis puas vim yog cov roj nplaum nplaum. , Cov xuab zeb zoo yog li 1 ~ 2kg / m2.
