Netiweki yothira madzi yopangidwa ndi gulu Ili ndi mphamvu yabwino kwambiri yotulutsa madzi, mphamvu yokoka komanso yolimbana ndi dzimbiri, ndipo imagwiritsidwa ntchito kwambiri popanga misewu, uinjiniya wa ngalande, malo otayira zinyalala komanso mapulojekiti osamalira madzi.
1. Kukonzekera musanamange
1、Kukonza maziko a khoka: Musanayike ukonde wothira madzi wophatikizika, maziko a khoka ayenera kutsukidwa bwino kuti atsimikizire kuti palibe zopinga zolimba monga miyala ndi zipilala pamwamba, ndipo kusalala ndi kukhuthala komwe kumafunikira pa kapangidwe kake kuyenera kukwaniritsidwa. Kusalala kosapitirira 15 mm， Mlingo wokhuthala uyenera kukwaniritsa miyezo ya kapangidwe ka uinjiniya. Pamwamba pa maziko a khoka ayenera kusungidwa ouma kuti apewe kukhudzidwa ndi chinyezi pa magwiridwe antchito a khoka lothira madzi.
2、Kuyang'anira zinthu: Kuyang'anira kwathunthu kwa netiweki yophatikizana yamadzi kuyenera kuchitika kuti zitsimikizire kuti palibe kuwonongeka, palibe kuipitsidwa, komanso kuti zikwaniritse zofunikira pa kapangidwe kake. Ndikofunikira kuyang'ana gawo lapakati la netiweki yothira madzi kuti zitsimikizire kuti kapangidwe kake ka magawo atatu ndi kokwanira komanso kuti palibe kusintha kapena kuwonongeka.
3, Nyengo: Mukayika netiweki yothira madzi, kutentha kwakunja kuyenera kukhala 5 ℃. Izi zidzachitika ngati nyengo ili pamwamba, mphamvu ya mphepo ili pansi pa mulingo wa 4, komanso popanda mvula kapena chipale chofewa kuti zitsimikizire kuti ntchito yomangayo ndi yabwino.
2. Zofunikira pakuyika ndi kuyika pamodzi
1. Njira yoyika: Netiweki yophatikizana yamadzi iyenera kuyikidwa pansi pa phiri kuti zitsimikizire kuti kutalika kwake kuli motsatira njira ya madzi. Pa mapiri ataliatali komanso otsetsereka, chisamaliro chapadera chiyenera kuperekedwa pakugwiritsa ntchito kutalika konse kwa chozungulira cha zinthu pamwamba pa phiri kuti zisakhudze momwe madzi amatulutsira chifukwa chodula.
2、Kuchiza zopinga: Mukakumana ndi zopinga (monga mapaipi otulutsira madzi kapena zitsime zowunikira) panthawi yoyika, dulani ukonde wotulutsira madzi ndikuwuyika mozungulira chopingacho kuti muwonetsetse kuti palibe mpata pakati pa chopingacho ndi zinthuzo. Mukadula, geotextile yapansi ndi geonet core ya composite drainage net ziyenera kukhudzana ndi zopinga, ndipo geotextile yapamwamba iyenera kukhala ndi malire okwanira kuti ibwerere pansi pa ukonde wotulutsira madzi kuti iteteze geonet core yowonekera.
3、Mode yolumikizirana: gawo lolumikizana la m'mphepete mwapafupi ndi kutalika kwa netiweki yophatikizana yamadzi ndi osachepera 100 mm. Gwiritsaninso ntchito HDPE pulasitiki yolumikiza lamba, lamba wolumikiza liyenera kukhala pamalo olemera. Shaft ya geonet imodzi ndi yapakati pa gawolo ndipo imadutsa mu shaft ya geonet imodzi. Malo olumikizirana olumikizirana m'mbali mwa mtunda ndi 150 mm. Malo olumikizirana pakati pa malo olumikizirana kumapeto onse a ngalande ya nangula ndi pansi pa malo otayira zinyalala ndi 150 mm. Mtundu wa gawo lolumikizana uyenera kukhala woyera kapena wachikasu kuti uwoneke mosavuta.
4、Kukonza geotextile yapamwamba: geotextile yapamwamba ndi yolemera pang'ono Stack 150 mm， Geotextile yapansi iyenera kulumikizidwa bwino. Geotextile yapamwamba ikhoza kulumikizidwa pamodzi posoka kapena kuwotcherera. Mzere umodzi wa singano ziwiri uyenera kugwiritsidwa ntchito pamalo olumikizirana, ndipo ulusi wosokera uyenera kukhala ndi zingwe zingapo, ndipo mphamvu yocheperako siyenera kupitirira 60 N， Iyeneranso kukhala ndi dzimbiri la mankhwala ndi kukana kwa ultraviolet kofanana ndi geotextile.
3. Kudzaza ndi kukanikiza
1、Zipangizo zosungira madzi: Mukamaliza kukonza netiweki yotulutsira madzi, kukonza malo osungira madzi kuyenera kuchitika nthawi yake. Zipangizo zosungira madzi ziyenera kupangidwa ndi miyala kapena mchenga wokonzedwa bwino, ndipo miyala ikuluikulu siyenera kugwiritsidwa ntchito kuti isawononge netiweki yotulutsira madzi.
2、Kukanikiza kwa zigawo: Zipangizo zoyikira kumbuyo ziyenera kukhala zokanikiza, ndipo makulidwe a gawo lililonse asapitirire 30 cm. Pakukanikiza, njira zopepuka zamakina kapena zamanja ziyenera kugwiritsidwa ntchito, ndipo kupanikizika kwakukulu sikuyenera kugwiritsidwa ntchito pa netiweki yotulutsira madzi. Gawo lokanikiza kumbuyo liyenera kukwaniritsa kuchuluka ndi kusalala komwe kumafunikira pa kapangidwe kake.
IV. Kuvomereza ndi kukonza zomangamanga
1、Kuchuluka kwa kuvomereza: Ntchito yomanga ikatha, mtundu wa malo olumikizirana madzi uyenera kuvomerezedwa mokwanira, monga momwe malo olumikizirana madzi amayendera, mtundu wa malo olumikizirana madzi, kupendekera kwake komanso kusalala kwa malo osungira madzi, ndi zina zotero. Onetsetsaninso kuti malo olumikizirana madzi sakutsekedwa ndipo onetsetsani kuti madzi akukwaniritsa cholinga chomwe mukufuna.
2、Kusamalira Kukonza: Pakugwiritsa ntchito, netiweki yophatikizana yamadzi iyenera kuyang'aniridwa ndikusamalidwa nthawi zonse. Zomwe zili mkati mwa kuwunikako zikuphatikizapo kukhulupirika kwa netiweki yotulutsa madzi, kulimba kwa zigawo zomwe zikulumikizana komanso momwe madzi akutulutsira madzi. Ngati papezeka mavuto, ayenera kuthetsedwa pakapita nthawi, ndipo kukhazikika ndi kulimba kwa kapangidwe ka uinjiniya kuyenera kusakhudzidwa.
