1. Kapangidwe ndi ntchito ya magawo atatunetiweki yotulutsira madzi yopangidwa ndi gulu
Netiweki yolumikizira madzi ya magawo atatu imakonzedwa pogwiritsa ntchito njira yapadera ya zinthu za polima monga polyethylene yochuluka kwambiri (HDPE) ndipo ili ndi mapangidwe atatu apadera: nthiti zapakati zimakhala zolimba ndipo zimakonzedwa motalikirapo kuti zipange njira zotulutsira madzi; nthitizo zimakonzedwa mopingasa ndikupangidwa. Zimathandizira kupewa geotextile kuti isalowe mu njira zotulutsira madzi, kusunga ntchito yayikulu yotulutsira madzi ngakhale ikanyamula katundu wambiri. Chifukwa chake, sikuti imangokhala ndi ntchito yabwino kwambiri yotulutsira madzi, komanso ili ndi ntchito zabwino kwambiri zoletsa kusefa, kupuma bwino komanso kuteteza.
2. Zizindikiro zazikulu za netiweki yotulutsira madzi yamitundu itatu
1. Kulemera pa dera lililonse: Kulemera pa dera lililonse ndi chizindikiro chofunikira poyesa makulidwe ndi kulemera kwa zinthu zolumikizirana ndi madzi zomwe zili ndi magawo atatu. Kawirikawiri, kulemera kwa chinthucho kukakhala kwakukulu, mphamvu ndi kulimba kwa chinthucho zimakhala bwino, koma mtengo wake umawonjezekanso. Chifukwa chake, posankha, kusinthana kuyenera kupangidwa kutengera zosowa za polojekiti ndi bajeti.
2. Kukhuthala: Kukhuthala ndi chizindikiro chofunikira cha makhalidwe enieni a maukonde ophatikizana amadzimadzi ophatikizana. Zipangizo zokhuthala zimakhala ndi mphamvu zokanikiza bwino komanso mphamvu zotulutsira madzi, koma zimawonjezeranso mtengo wa zipangizo komanso zovuta zomangira. Sankhani makulidwe oyenera malinga ndi momwe polojekitiyi ilili.
3. Mphamvu yokoka: Mphamvu yokoka ndi chizindikiro chofunikira poyesa mphamvu ya makina a maukonde ophatikizana amitundu itatu. Zimawonetsa mphamvu ya zinthuzo ponyamula katundu molunjika ku kukoka. Mu mapulojekiti osamalira madzi ndi mainjiniya a zomangamanga, zipangizo zomwe zili ndi mphamvu yokoka kwambiri zimatha kukana kukokoloka kwa madzi ndi kusintha kwa nthaka, kuonetsetsa kuti kapangidwe kake ka uinjiniya kali kokhazikika komanso kotetezeka.
4. Mphamvu yokakamiza: Mphamvu yokakamiza imatanthauza mphamvu yonyamula katundu ya netiweki yophatikizana ya magawo atatu mbali imodzi kumbali yoyima. Pa mapulojekiti omwe amafunika kupirira katundu waukulu, monga misewu ikuluikulu, sitima zapansi panthaka, ndi zina zotero, mphamvu yokakamiza ndiyofunika kwambiri.
5. Kugwira ntchito bwino kwa madzi otuluka m'nthaka: Kugwira ntchito bwino kwa madzi otuluka m'nthaka ndi chimodzi mwa ntchito zazikulu za netiweki yophatikizana yamadzi otuluka m'nthaka. Ili ndi magawo monga kulowerera ndi kuchuluka kwa madzi otuluka m'nthaka, zomwe zingasonyeze momwe zinthuzo zimagwirira ntchito bwino panthawi ya madzi otuluka m'nthaka. Kugwira ntchito bwino kwa madzi otuluka m'nthaka kungathandize kuchepetsa kuthamanga kwa madzi m'nthaka, kuletsa nthaka kuti isasungunuke ndi kutsetsereka, komanso kukonza kukhazikika ndi chitetezo cha polojekitiyi.
6. Kukana nyengo ndi dzimbiri: M'malo akunja, netiweki yotulutsira madzi yokhala ndi magawo atatu iyenera kupirira nyengo zovuta monga mphepo, dzuwa, kukokoloka kwa mvula. Chifukwa chake, kukana nyengo ndi dzimbiri ndi zizindikiro zofunika kwambiri poyesa nthawi yogwirira ntchito ndi magwiridwe antchito ake. Kusankha zipangizo zomwe zimakana nyengo ndi dzimbiri kungathandize kuonetsetsa kuti pulojekitiyi ndi yokhazikika komanso yotetezeka panthawi yogwira ntchito kwa nthawi yayitali.
3. Malangizo posankha netiweki yotulutsira madzi yokhala ndi magawo atatu
Posankha netiweki yothira madzi yokhala ndi magawo atatu, ndikofunikira kuganizira mozama kutengera zinthu monga zosowa za uinjiniya, momwe zinthu zilili pa nthaka, kuvutika kwa zomangamanga komanso bajeti ya ndalama. Ndikofunikira kusankha netiweki yothira madzi yokhala ndi magawo atatu yokhala ndi mphamvu zambiri, modulus yayikulu komanso magwiridwe antchito abwino amadzimadzi pamapulojekiti omwe amafunikira kumanga mwachangu, mtengo wotsika komanso mphamvu zochepa. Pa uinjiniya, mutha kusankha zipangizo zomwe zimagwira ntchito bwino komanso zotsika mtengo.
