Geotextilesmachira anopindika ayo, kana akashandiswa mukubatana nevhu, anokwanisa kupatsanura, kusefa, kusimbisa, kudzivirira, kana kudhiza.Anowanzo gadzirwa kubva ku polypropylene kana polyester, geotextile machira anouya ari matatu akakosha mafomu: akarukwa (akafanana netsamba bhegi sacking), tsono yakabaiwa (yakafanana nekunzwa), kana kupisa kwakasungwa (kufanana neaini yakanzwa).
Geotextile macomposites akaunzwa uye zvigadzirwa zvakaita segeogrids uye meshes zvakagadziridzwa.Geotextiles yakasimba, uye inokwanisa kupfavisa kudonha kana mumwe munhu akadonha.Pakazere, zvinhu izvi zvinonzi geosynthetics uye gadziriso yega yega-geonets, geosynthetic clay liners, geogrids, geotextile machubhu, uye nezvimwe-zvinogona kuunza mabhenefiti mune geotechnical uye nharaunda engineering dhizaini.
Nhoroondo
Nemachira e geotextile ari kushandiswa zvakanyanya pamabasa emazuva ano anoshanda, zvakaoma kutenda kuti tekinoroji iyi haina kana kumbovapo makumi masere emakore apfuura.Iyi tekinoroji inowanzoshandiswa kupatsanura mavhu, uye yashanduka kuita indasitiri yemabhiriyoni emadhora.
Geotextiles pakutanga akagadzirirwa kuve imwe nzira kune granular ivhu mafirita.Yekutanga, uye ichiri kushandiswa dzimwe nguva, izwi rekuti geotextiles machira esefa.Basa rakatanga muna 1950s naRJ Barrett vachishandisa geotextiles kuseri kwe precast kongiri madziro egungwa, pasi pe precast kongiri yekudzivirira erosion block block, pasi pehombe yedombo riprap, uye mune mamwe mamiriro ekudzora kukurwa.Akashandisa zvitaera zvakasiyana zvemachira akarukwa emonofilament, ese anoratidzwa neyakavhurika chikamu chepamusoro (inosiyana kubva pa6 kusvika ku30%).Akakurukura kudiwa kwezvose zvakaringana permeability uye kuchengetedzwa kwevhu, pamwe nekusimba kwejira rakakwana uye kurebesa kwakakodzera uye kuseta toni yekushandiswa kwe geotextile mumamiriro ekusefa.
Applications
Geotextiles uye zvigadzirwa zvine hukama zvine maapplication akawanda uye parizvino zvinotsigira akawanda einjiniya zvikumbiro zvinosanganisira migwagwa, nhandare dzendege, njanji, mabhenji, zvivakwa zvekuchengetedza, madhamu, migero, madhamu, kuchengetedzwa kwebhangi, engineering yemahombekombe uye nzvimbo yekuvaka silt fenzi kana geotube.
Kazhinji geotextiles anoiswa panzvimbo yekumanikidza kusimbisa ivhu.Geotextiles anoshandiswawo kune jecha dune armoring kudzivirira kumusoro kwemahombekombe nzvimbo kubva kune dutu remhepo, mafungu chiitiko uye mafashama.Chigadziko chihombe chakazadzwa nejecha (SFC) mukati medune system inodzivirira kukukurwa nedutu kupfuurira kupfuura SFC.Kushandisa sloped unit kwete chubhu imwe chete kunobvisa kukuvadza.
Mabhuku ekudzora kukukurwa kwevhu anotsinhira pamusoro pekubudirira kwezvimiro zvakatenuka, zvakatsikwa mukuderedza kukuvadzwa kwekukukurwa kwemahombekombe kubva kumadutu.Geotextile jecha-akazadzwa mayuniti anopa "yakapfava" yezvombo mhinduro yeupland pfuma kuchengetedza.Geotextiles anoshandiswa semateti kudzikamisa kuyerera mumatanho erukova uye swales.
Geotextiles inogona kuvandudza simba revhu pamutengo wakaderera pane yakajairwa ivhu mbambo.Mukuwedzera, geotextiles inobvumira kudyara pamateru, ichiwedzera kuchengetedza kutsetseka.
Geotextiles akashandiswa kuchengetedza fossil hominid tsoka dzeLaetoli muTanzania kubva mukukukurwa, mvura, uye midzi yemiti.
Mukuvaka kuparadza, machira e geotextile akasanganiswa nesimbi waya fencing anogona kuve nemarara anoputika.
