Geotextile imagwiritsidwa ntchito makamaka m'malo mwa zinthu zakale za granular kuti apange zosefera zopindika ndi ngalande.Poyerekeza ndi chikhalidwe inverted fyuluta ndi ngalande thupi, ili ndi makhalidwe a kulemera kuwala, zabwino zonse kupitiriza, yomanga yabwino, mkulu kakokedwe mphamvu, kukana dzimbiri, zabwino tizilombo kukana kukokoloka kwa tizilombo toyambitsa matenda, mawonekedwe ofewa, kugwirizana kwabwino ndi nthaka zipangizo, mkulu durability ndi nyengo. kukana pansi pa madzi kapena m'nthaka, komanso kugwiritsa ntchito modabwitsa Ndipo geotextile imakumananso ndi zinthu zosefera zosinthika: 1 Kusamalira nthaka: kupewa kutayika kwa dothi lotetezedwa, kupangitsa kuti madzi asokonezeke, 2 Kuthekera kwamadzi: kuonetsetsa kuti madzi akuyenda bwino. madzi, 3 Anti-kutsekereza katundu: kuonetsetsa kuti sichidzatsekedwa ndi tinthu tating'onoting'ono tadothi.

Geotextile idzapatsidwa satifiketi yamtundu wazinthu ikagwiritsidwa ntchito, ndipo zisonyezo zakuthupi zidzayesedwa: misa pagawo lililonse, makulidwe, kabowo kofanana, ndi zina zolozera zamakina: kulimba kwamphamvu, kugwetsa mphamvu, mphamvu yogwira, kuphulika kwamphamvu, kuphulika. mphamvu, kugunda mphamvu ya zinthu nthaka mogwirizana, etc Zizindikiro Hydraulic: ofukula permeability coefficient, ndege permeability coefficient, gradient chiŵerengero, ndi zina Kukhalitsa: kukana kukalamba, kukana dzimbiri mankhwala Mayeso adzachitidwa ndi oyenerera luso luso dipatimenti yoyendera.Panthawi yoyeserera, zinthu zowunikira zitha kuwonjezeredwa kapena kuchotsedwa malinga ndi zosowa za polojekiti komanso zofunikira pakumanga, ndipo lipoti lowunikira latsatanetsatane lidzaperekedwa.
Pakuyika kwa geotextile, malo olumikiziranawo amayenera kukhala osasunthika popanda kusagwirizana, miyala, mizu yamitengo kapena zinyalala zina zomwe zingawononge geotextile Mukayika geotextile, siyenera kukhala yolimba kwambiri kuti mupewe kupindika kwambiri komanso kung'ambika kwa geotextile panthawi yoyika. kumanga.Choncho, m'pofunika kusunga mlingo wina wa zothina.Ngati ndi kotheka, geotextile imatha kupanga geotextile kukhala ndi mikwingwirima yofananira Poika geotextile: choyamba ikani geotextile kuchokera kumtunda kwa gawo lokulunga pansi, ndikuyiyika chipika ndi chipika molingana ndi nambala.M'lifupi mwake pakati pa midadada ndi 1m.Mukayika mutu wozungulira, chifukwa chapamwamba chopapatiza komanso chotsika kwambiri, chisamaliro chapadera chiyenera kuperekedwa pakuyika, kumangidwa mosamalitsa kudzachitika, ndipo m'lifupi mwake pakati pa midadada iyenera kutsimikiziridwa Mgwirizano pakati pa geotextile ndi maziko a madamu ndi banki. Iyenera kugwiridwa bwino Poika, tiyenera kupitirizabe ndipo tisadzaphonye kuyala Pambuyo poyika geotextile, sichitha kuwululidwa ndi dzuwa chifukwa geotextile imapangidwa ndi zinthu zopangira mankhwala Kuwala kwa dzuwa kumawononga mphamvu, choncho njira zotetezera ziyenera kuchitidwa. kutengedwa.
Njira zathu zodzitetezera pakumanga kwa geotextile ndi: kuphimba geotextile yoyala ndi udzu, zomwe zimawonetsetsa kuti geotextile sidzawonetsedwa ndi dzuwa, komanso imagwira ntchito bwino poteteza geotextile kuti imange mwala pambuyo pake imawonjezedwa ndipo ntchito yomanga miyala ikuchitika pa geotextile, geotextile idzatetezedwa mosamala Kuwonjezera apo, ndondomeko yabwino kwambiri yomanga idzasankhidwira njira yomanga miyala Njira yathu yomanga ndi yakuti, chifukwa cha kuchuluka kwa makina omangamanga. , mwalawu umanyamulidwa ndi magalimoto otaya zinyalala.Pakutsitsa mwala, munthu wapadera amasankhidwa kuti aziwongolera galimotoyo kuti atsitse mwalawo, ndipo mwalawo umatsitsidwa kunja kwa mbiya yamiyala. Tanki yosinthira pamanja iyenera kusamaliridwa mosamala kuti isawononge geotextile Choyamba, kulungani mwala wonse pamodzi. pansi pa ngalandeyo ndi 0.5m.Panthawiyi, anthu ambiri amatha kuponya miyala motsatira mwala wa chotchingacho mosamala.Ngalandeyo ikadzadza, sinthani pamanja miyalayo m'mphepete mwa mtsinje wa nthaka.M'lifupi mwalawo ndi wofanana ndi wofunikira ndi mapangidwe.Mwalawo uyenera kukwezedwa mofanana potaya mwala.Mwala pamwamba pa chotchinga m'mphepete mwa otsetsereka sadzakhala okwera kwambiri Ngati ndi okwera kwambiri, si otetezeka kwa filament nsalu geotextile, ndipo akhoza kutsetsereka pansi, kuwononga geotextile Choncho, chidwi chapadera chiyenera kuperekedwa. kuchitetezo pomanga Miyala yopyapyala ikayalidwa mkatikati mwa matayala a dothi kufika pa 2m kuchoka pa madamu, miyalayo ikulungidwa motsetsereka mkati mwake, ndipo makulidwe ake asapitirire 0.5m.Miyalayo idzatsitsidwa kumtsinje wa damu, ndipo miyalayo iyenera kutayidwa mosamala, ndipo miyalayo idzaphwanyidwa pamene ikuponyedwa mpaka itaphwanyidwa pamwamba pa nthaka. idzasinthidwa kuti ifike pamtunda wosalala.
① Wosanjikiza wodzitchinjiriza: ndi gawo lakunja lomwe limalumikizana ndi dziko lakunja.Amayikidwa kuti ateteze ku zotsatira za kutuluka kwa madzi kunja kapena mafunde, nyengo ndi kukokoloka, kuzizira ndi kuwononga mphete ndi kuteteza kuwala kwa ultraviolet kwa dzuwa.Kuchuluka kwake kumakhala 15-625px.
② Khushoni yapamwamba: ndi gawo losinthira pakati pa gawo loteteza ndi geomembrane.Popeza wosanjikiza zoteteza zambiri zidutswa zazikulu za zinthu akhakula ndi zosavuta kusuntha, ngati mwachindunji anaika pa geomembrane, n'zosavuta kuwononga geomembrane.Choncho, chapamwamba khushoni ayenera bwino okonzeka.Nthawi zambiri, pamakhala miyala yamchenga, ndipo makulidwe ake sayenera kuchepera 375px.
③ Geomembrane: ndiye mutu wa kupewa kuseweredwa.Kuphatikiza pa kupewa kutsekeka kodalirika, iyeneranso kupirira zovuta zina zomanga ndi kupsinjika komwe kumachitika chifukwa chokhazikika pamagwiritsidwe ntchito.Choncho, palinso zofunika mphamvu.Mphamvu ya geomembrane imagwirizana mwachindunji ndi makulidwe ake, omwe angadziwike kudzera mu mawerengedwe amalingaliro kapena luso laumisiri.
④ Mtsinje wapansi: woyikidwa pansi pa geomembrane, uli ndi ntchito ziwiri: imodzi ndiyo kuchotsa madzi ndi mpweya pansi pa nembanemba kuti zitsimikizire kukhazikika kwa geomembrane;china ndikuteteza geomembrane ku kuwonongeka kwa wosanjikiza wothandizira.
⑤ Thandizo lothandizira: geomembrane ndi chinthu chosinthika, chomwe chiyenera kuikidwa pazitsulo zodalirika zothandizira, zomwe zingapangitse geomembrane kupanikizika mofanana.
