Kodi ndi zinthu ziti zomwe netiweki yotulutsira madzi yopangidwa ndi composite imakhala nazo?

Maukonde otulutsa madzi ophatikizika ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri potaya zinyalala, misewu, makoma amkati mwa ngalande ndi ntchito zina. Ndiye, kodi zigawo za maukonde otulutsa madzi ophatikizika ndi ziti?

Ukonde wophatikizana wothira madzi umapangidwa ndi pulasitiki yokhala ndi ma mesh atatu ndi geotextile yolumikizira mbali ziwiri yomwe imalowa madzi. Kuphatikiza kumeneku sikuti kumangopatsa ukonde wophatikizana mphamvu yothira madzi, komanso kumapangitsa kuti ukhale ndi ubwino wokhala ndi mphamvu yolimba, kukana dzimbiri komanso kukhala ndi moyo wautali.

1. Chimake cha pulasitiki ndi gawo lalikulu la ukonde wothira madzi wophatikizika. Chimapangidwa ndi polyethylene yapamwamba kwambiri (HDPE) ndipo chimakonzedwa ndi njira yapadera yopangira madzi. Chimake cha pulasitiki ichi chili ndi kapangidwe kapadera ka magawo atatu. Nthiti zapakati ndi zolimba ndipo zimakonzedwa motalikirapo kuti zipange njira yothira madzi; nthiti zokonzedwa mopingasa mmwamba ndi pansi zimapanga chithandizo choletsa geotextile kuti isalowe mu njira yothira madzi. Ngakhale pansi pa katundu wolemera kwambiri, chimake cha pulasitiki chimatha kusunga ntchito yabwino yothira madzi. Mphamvu yayitali komanso yopingasa komanso mphamvu yokakamiza ya chimake cha pulasitiki ndi yayikulu, zomwe zingatsimikizire kukhazikika ndi kudalirika kwa ukonde wothira madzi wophatikizika panthawi yogwiritsidwa ntchito kwa nthawi yayitali.

2. Geotextile yolowa madzi ndi chinthu china chofunikira kwambiri pa ukonde wothira madzi wophatikizika. Nthawi zambiri imagwiritsa ntchito zinthu monga nsalu ya polyester filament, nsalu ya polyester staple fiber kapena nsalu ya polypropylene staple fiber. Ntchito yayikulu ya geotextile ndikusefa zinyalala, kuonetsetsa kuti pakati pa ukonde pali njira yosalala, ndikutulutsa madzi nthawi yake. Geotextile imathanso kulumikizidwa mwamphamvu ndi pakati pa ukonde wa pulasitiki kuti ipange kapangidwe kophatikizana ka madzi othira madzi, komwe kungathandize kuti madzi azigwira bwino ntchito komanso kuti ukonde wothira madzi ukhale ndi moyo wautali.

3. Kuwonjezera pa zigawo ziwiri zazikulu zomwe zili pamwambapa, ukonde wothira madzi wophatikizika ukhozanso kusinthidwa malinga ndi zosowa za makasitomala panthawi yopanga. Mwachitsanzo, geotextile yophatikizika mbali zonse ziwiri ikhoza kukhala nsalu ya ulusi, nsalu yaufupi ya ulusi, nsalu yobiriwira kapena nsalu yakuda. Kusinthasintha kumeneku kumalola ukonde wothira madzi wophatikizika kuti ugwirizane bwino ndi zosowa za mapulojekiti osiyanasiyana ndikuwongolera magwiridwe antchito onse ndi zabwino za polojekitiyi.

Ukonde wophatikizana wothira madzi ungagwiritsidwe ntchito m'malo ambiri monga malo otayira zinyalala, malo oimikapo zinyalala, ndi makoma amkati mwa ngalande. Sungathe kungotulutsa madzi omwe asonkhana pakati pa maziko ndi pansi, kutseka madzi a capillary, komanso kukweza mphamvu yothandizira maziko ndikuwonjezera moyo wa ntchito ya msewu. Kuphatikiza apo, uli ndi ubwino womanga mosavuta, nthawi yocheperako yomanga komanso ndalama zochepa.

Monga momwe taonera pamwambapa, ukonde wothira madzi wophatikizika umapangidwa ndi zinthu ziwiri: pulasitiki yokhala ndi maukonde atatu ndi geotextile yolumikizira mbali ziwiri. Chifukwa chake, ntchito yake yothira madzi ndi yabwino kwambiri ndipo ingagwiritsidwe ntchito pa ntchito zazikulu.
