1. Kapangidwe ka netiweki yotulutsira madzi yophatikizika
Mesh yophatikizana yotulutsa madzi imaphatikizidwa ndi zigawo ziwiri kapena zingapo za core ya drainage mesh ndi geotextile. core ya drainage mesh nthawi zambiri imapangidwa ndi polyethylene yochuluka kwambiri (HDPE) Monga zipangizo zopangira, njira yotulutsira madzi yokhala ndi mawonekedwe atatu imapangidwa ndi extrusion molding kudzera mu njira yapadera. Geotextile imagwira ntchito ngati fyuluta wosanjikiza kuti tinthu ta dothi tisadutse ndikuteteza core ya drainage mesh.
2. Kusiyana pakati pa nsalu yaufupi ya ulusi ndi nsalu yayitali ya ulusi
Mu gawo la ma geotextiles, nsalu yaifupi ya ulusi ndi nsalu yayitali ya ulusi ndi mitundu iwiri yodziwika bwino ya zinthu. Nsalu yaifupi ya silika imapangidwa ndi polyester staple fiber needle punch, yomwe imalowa bwino kwambiri mumlengalenga komanso imalowa bwino m'madzi, koma mphamvu yake ndi kulimba kwake ndizochepa. Nsalu ya ulusi imapangidwa ndi polyester filament spunbond, yomwe imakhala ndi mphamvu komanso kulimba kwambiri, komanso imasefa bwino kwambiri.
3. Kufunika kwa ma geotextiles mu maukonde ophatikizana amadzi otayira madzi
Netiweki yolumikizira madzi yopangidwa ndi gulu la Composite imagwira ntchito ziwiri monga kukhetsa madzi ndi kulimbikitsa ntchitoyo. Chifukwa chake, pali zofunikira kwambiri pakusankha ma geotextile. Kumbali imodzi, geotextile iyenera kukhala ndi magwiridwe antchito abwino kwambiri osefera, zomwe zingalepheretse tinthu ta dothi kudutsa ndikuletsa kuti maukonde a madzi asatseke. Kumbali inayi, ma geotextile ayenera kukhala ndi mphamvu zambiri komanso kulimba, komanso athe kupirira katundu ndi kugwiritsidwa ntchito kwa nthawi yayitali muukadaulo.
4. Kugwiritsa ntchito nsalu yaufupi ya ulusi ndi nsalu yayitali ya ulusi mu ukonde wothira madzi wophatikizika
1. Pakugwiritsa ntchito kwenikweni, kusankha kwa geotextile ya netiweki yothira madzi yophatikizika nthawi zambiri kumadalira zosowa ndi mikhalidwe yeniyeni ya polojekitiyi. Pa mapulojekiti omwe amafunikira mphamvu zambiri komanso kulimba, monga mapulojekiti oyenda magalimoto ambiri monga misewu yayikulu ndi njanji, komanso mapulojekiti omwe amafunika kunyamula katundu wautali komanso malo ovuta monga malo otayira zinyalala ndi makoma osungira madzi, nsalu ya filament nthawi zambiri imagwiritsidwa ntchito ngati gawo losefera la ma netiweki othira madzi ophatikizika. Chifukwa nsalu ya filament ili ndi mphamvu zambiri komanso kulimba, imatha kukwaniritsa zosowa za mapulojekitiwa bwino.
2、Pa mapulojekiti ena omwe safuna mphamvu zambiri, monga misewu wamba, malamba obiriwira, ndi zina zotero, nsalu yaifupi ya silika ingagwiritsidwenso ntchito ngati gawo losefera la maukonde ophatikizana otulutsa madzi. Ngakhale kuti nsalu yaifupi ya silika ndi yolimba komanso yolimba, ili ndi mpweya wabwino komanso madzi okwanira, zomwe zingakwaniritse zosowa za mapulojekitiwa.
5. Ubwino wosankha nsalu ya ulusi
Ngakhale nsalu yaulusi yayifupi imagwira ntchito zina m'mapulojekiti ena, nsalu yayitali yaulusi imagwiritsidwa ntchito kwambiri mu ukonde wothira madzi wophatikizika. Makamaka chifukwa nsalu yaulusiyo ili ndi mphamvu zambiri komanso kulimba, ndipo imatha kupirira bwino katundu ndi kugwiritsidwa ntchito kwa nthawi yayitali mupulojekitiyi. Nsalu yaulusiyo ilinso ndi magwiridwe antchito abwino osefera, zomwe zingalepheretse tinthu ta dothi kudutsa ndikuletsa kuti maukonde amadzi asatseke. Nsalu yaulusiyo ilinso ndi mphamvu zabwino zotsutsana ndi dzimbiri komanso zoletsa ukalamba, ndipo ingagwiritsidwe ntchito m'malo ovuta kwa nthawi yayitali popanda kulephera.
Kuchokera pamwambapa, zitha kuwoneka kuti mtundu wa geotextile womwe umagwiritsidwa ntchito mu projekitiyi pa netiweki yotulutsa madzi yophatikizika umadalira zosowa ndi mikhalidwe ya projekitiyi. Ngakhale nsalu yayifupi ya ulusi imagwiritsidwa ntchito m'ma projekiti ena, nsalu yayitali ya ulusi imagwiritsidwa ntchito kwambiri mu ukonde wotulutsa madzi wophatikizika chifukwa cha mphamvu zake zapamwamba, kulimba kwake komanso magwiridwe antchito abwino kwambiri osefera.
