American Society of Agriculture engineers hais txog geotextiles raws li cov ntaub ntawv ntawm geotextiles los yog geotechnical Cheebtsam ntawm cov av thiab cov kav dej, gabions los yog khaws cov phab ntsa.Cov ntaub ntawv no tuaj yeem txhim kho kev txav ntawm cov dej thiab cuam tshuam kev txav ntawm cov av.Geotextile, tseem hu ua geotextile, yog ib hom ntaub ntawv permeable ua los ntawm cov ntaub ntawv geotechnical.Nws yog siv rau cov av, pob zeb, av los yog lwm yam geotechnical engineering cov ntaub ntawv, thiab ua ib feem ntawm cov khoom siv dag zog kom ua tiav cov qauv tsim.Geotextile cov ntaub ntawv yuav tsum tsis tsuas yog xav txog lub cev thiab tshuaj lom neeg cov khoom uas yuav tsum tau los ntawm daim ntawv thov ib puag ncig, tab sis kuj xyuam xim rau cov nqi khoom.
Geotextile yog cov khoom siv hydraulic zoo heev
Thaum cov dej hauv cov txheej hauv av ntxuav cov khoom ntxhib hauv cov txheej hauv av, rab koob punched geotextile nrog permeability zoo heev thiab permeability yog siv los ua kom cov dej ntws los ntawm thiab tiv thaiv kom tsis txhob ntws ntawm cov av, xov paj, pob zeb me me, thiab lwm yam. thiaj li los xyuas kom meej stability ntawm dej thiab av engineering.Cov dej ntws tawm ntawm geotextile geotextile yog ib yam khoom siv dej zoo heev.Nws tuaj yeem tsim cov dej ntws hauv cov av thiab tso cov kua roj seem ntawm lub cev.Kev siv zog ntxiv ntawm geotextile rab koob zoo li geotextile yog siv los txhim kho lub zog tensile thiab tsis kam rau cov av hloov pauv, ua kom muaj kev ruaj ntseg ntawm lub tsev, thiab txhim kho av zoo.
Txoj kev tsim kho ntawm filament geotextile yog raws li nram no:
1. cov filament geotextile yuav tsum tau nteg los ntawm phau ntawv dov txoj kev, thiab daim ntaub nto yuav tsum tiaj tus nrog rau qhov tsim nyog deformation pub;
2. lub tshuab xaws tes yuav tsum tau siv rau xaws cov filament geotextile, thiab lub sij hawm ib teev yuav tsum tau tswj ntawm li 6 hli.Lub zog stitching ntawm sab sauv geotextile thiab lub hauv paus geotextile yuav tsum tsis pub tsawg tshaj 70% ntawm lub zog ntawm geotextile nws tus kheej.
3. xaiv txoj kev splicing ntawm filament geotextile, thiab qhov dav splicing yuav tsum tsis pub tsawg tshaj 0.1 M;
4. tag nrho cov stitches yuav tsum tau nqa tawm tsis tu ncua, thiab tsis muaj qhov taw tes stitch raug tso cai.Qhov tsawg kawg nkaus koob deb yog 2.50cm;
5. cov xov siv los xaws yuav tsum yog cov khoom siv cob nrog qhov tsawg kawg nkaus ntawm kev sib txhuam ntawm ntau tshaj 60N, thiab muaj qhov tsim nyog los yog ultra-siab chemical corrosion kuj thiab ultraviolet hluav taws xob tsis kam ntawm geotextile;
6. nyob rau hauv cov ntaub ntawv ntawm koob hla thiab lwm yam tsis tsim nyog tshwm sim, kho los ntawm kos ntawm suture
