Ubwino woyika netiweki yothira madzi yopangidwa ndi miyeso itatu pansi

Netiweki yolumikizira madzi yokhala ndi magawo atatu. Imayikidwa pakati pa maziko ndi pansi kuti itulutse madzi osonkhanitsidwa pakati pa maziko ndi pansi, kutseka madzi a capillary ndikulowa bwino mu dongosolo la madzi otuluka m'mphepete. Kapangidwe kameneka kamafupikitsa njira yotulutsira madzi ya maziko, kufupikitsa nthawi yotulutsira madzi, kuchepetsa kuchuluka kwa zipangizo zosankhidwa zomwe zimagwiritsidwa ntchito, komanso kutalikitsa moyo wa msewu. Netiweki yolumikizira madzi yokhala ndi magawo atatu Yopangidwa ndi geotextile yapadera yokhala ndi magawo atatu yokhala ndi mbali ziwiri. Imaphatikiza geotextile (anti-filtration action) ndi geonet (drainage and protection action) kuti ipereke mphamvu yonse ya "anti-filtration-drainage-protection". Kuyika netiweki yolumikizira madzi yokhala ndi magawo atatu kungathandize kuchepetsa zotsatira za chisanu. Ngati kuzama kwa kuzizira kuli kozama kwambiri, geonet ikhoza kuyikidwa pamalo osaya kwambiri mu substrate ngati kutsekeka kwa capillary. Kuphatikiza apo, nthawi zambiri ndikofunikira kuisintha ndi subbase yokhala ndi granular yomwe siimakonda chisanu, mpaka kuzama kwa kuzizira. Dothi lodzaza madzi lomwe limakonda kuzizira kwambiri likhoza kudzazidwa mwachindunji pa netiweki yophatikizana ya magawo atatu mpaka pansi pa maziko. Pankhaniyi, dongosololi likhoza kulumikizidwa ku malo otulutsira madzi kuti madzi apansi panthaka akhale ofanana kapena pansi pa digiri iyi ya kuya. Mwanjira imeneyi, kukula kwa makhiristo opanga ayezi kungakhale kochepa, ndipo palibe chifukwa chochepetsera kuchuluka kwa anthu omwe amadutsa madziwo akasungunuka m'nyengo yozizira.

Pakadali pano, njira yayikulu yomangira kulumikizana kwa netiweki yolumikizira madzi yokhala ndi magawo atatu ndi kuphatikizana, kulumikizana, kusoka:

Mzere: pafupiNetiweki yotulutsira madzi ya Geocomposite Geotextile ya pansi imalumikizana pakati pawo. Kulumikizana: Pakati pa netiweki yotulutsira madzi pakati pa netiweki yotulutsira madzi ya geocomposite yoyandikana imalumikizidwa ndi waya wachitsulo, zomangira za pulasitiki kapena malamba a nayiloni. Kusoka: Geotextile yomwe ili pafupi ndi netiweki yotulutsira madzi ya geocomposite imasokedwa ndi makina osokera onyamulika.

Kapangidwe kapadera kamene kali ndi magawo atatu kamene kali ndi gawo limodzi la core ya drainage composite kakhoza kupirira kupsinjika kwakukulu panthawi yonse yogwiritsira ntchito, ndipo kamatha kusunga makulidwe ambiri, kupereka mphamvu yabwino ya hydraulic.

Mbale yotsutsana ndi madzi (yomwe imadziwikanso kuti neti yophatikizana yamitundu itatu, gridi yotulutsa madzi) ndi mtundu watsopano wa zinthu za geotechnical zotulutsira madzi. Ndi polyethylene yochuluka kwambiri (HDPE) Monga zipangizo zopangira, imakonzedwa ndi njira yapadera yopangira madzi ndipo ili ndi zigawo zitatu zapadera. Nthiti zapakati zimakhala zolimba ndipo zimakonzedwa motalikirapo kuti zipange njira yotulutsira madzi, ndipo nthiti zapamwamba ndi zapansi zokonzedwa bwino zimapanga chithandizo choletsa geotextile kuti isalowe mu njira yotulutsira madzi, yomwe imatha kusunga ntchito yayikulu yotulutsira madzi ngakhale ikanyamula katundu wambiri. Geotextile yolumikizidwa mbali ziwiri yolumikizidwa ndi madzi imagwiritsidwa ntchito pamodzi, yomwe ili ndi mphamvu zonse za "kuteteza kusefa-kutulutsa madzi-kupuma-kubwerera" ndipo pakadali pano ndi chinthu chabwino kwambiri chotulutsira madzi.
