Akuti iyi ndi njira yopangira tsiku ndi tsiku yaunyolo ulalo mpandamankhwala. Opanga mipanda yolumikizira unyolo amagwiritsidwa ntchito kuteteza ndi kuthandizira ma seawall, mapiri, misewu ndi milatho, malo osungiramo madzi ndi zomangamanga zina. Ndizinthu zabwino zowongolera kusefukira kwamadzi komanso kukana kusefukira. Itha kugwiritsidwanso ntchito popanga zamanja. Malo osungiramo zinthu, firiji ya chipinda cha zida, kulimbitsa chitetezo, mpanda wa usodzi wam'nyanja ndi mpanda wa malo omanga, njira yamtsinje, nthaka yotsetsereka (mwala), chitetezo chanyumba, ndi zina.
Mpanda wolumikizira unyolo wamagalasimakamaka utenga zotsatira zapadera za mpweya permeability wa unyolo kugwirizana mpanda, amene chimagwiritsidwa ntchito pa phiri chitetezo, ntchito kukonza miyala, ndi kupopera mbewu mankhwalawa ndi udzu wobiriwira kukwaniritsa zotsatira za kudziletsa mu siteji yotsatira. Ndi kuphatikiza koyenera kwa kubiriwira ndi chitetezo. Mpanda wachitsulo chosapanga dzimbiri umagwiritsa ntchito mbali iyi kuti ikwaniritse ntchito zokutira. Kufanana kwa chikhalidwe cha ufa wamadzimadzi mu bedi lamadzimadzi ndilo chinsinsi chowonetsetsa kuti filimu yophimba ikhale yofanana.
Bedi lamadzimadzi lomwe limagwiritsidwa ntchito popaka ufa ndi la "vertical fluidization", ndipo nambala ya fluidization iyenera kupezeka kudzera muzoyesera. Nthawi zambiri, imatha kuphimbidwa. Kuyimitsidwa kwa ufa mu bedi lamadzimadzi kumatha kufika ku 30-50%. Pamene mtunda wa mayendedwe a mesh welded ndi wautali, nthawi zambiri ndi 2.0-2.4 metres mulifupi (kutengera misewu kapena mayendedwe anjanji). Kutalika kwakukulu kwa ma mesh wowotcherera sikuyenera kupitirira 12m (mayendedwe anjanji kapena mayendedwe apamsewu) ndi 6m (mayendedwe apamsewu). M'zaka zaposachedwapa, chiwerengero chachikulu cha profiled zitsulo mbale zaonekera mu kuwala zitsulo dongosolo dongosolo. Hot-dip galvanizing amagwiritsidwanso ntchito kwambiri poletsa dzimbiri. Njira yoyamba yopangira galvanizing yotentha ndikuchotsa dzimbiri, kenako ndikuyeretsa.
Mayendedwe a mpanda wa bwaloli wophatikizidwa ndiwosavuta ndipo mtengo wamayendedwe ndi wotsika. Chifukwa chakuti mpanda wa sitediyamu usanasonkhanitsidwe, mizati yoperekedwa, mizati ndi mipanda ndi chinthu chimodzi ndipo iyenera kulumikizidwanso pamalo omangawo. Choncho pamene kutumiza katundu kuwerengera katundu wa katundu wolemera monga maziko, katunduyo amakhala wochepa. Nthawi zambiri, chitsulo okusayidi wa carbon zitsulo ndi okusayidi chitsulo, ndi makutidwe ndi okosijeni wa chitsulo okusayidi adzakhala dzimbiri, zomwe zimakhudza maonekedwe ndi moyo utumiki wa mankhwala. Komano, mesh yachitsulo chosapanga dzimbiri imakhala ndi 11.7% ya chromium, yomwe imalumikizana ndi okosijeni kuti ipange ma oxides, ndikupanga filimu ya passivation, yomwe imalepheretsa kuwonjezereka kwa chitsulo ndi chromium ndi okosijeni.
Chikhalidwe cholimba cha mauna a mbedza ndikumatira pakati pa zosanjikiza zamagalasi ndi zitsulo. Chofunikira chachikulu ndi chakuti zida za malata zisavumbulutsidwe pakumalizidwa, kunyamula, kusungirako ndikugwiritsa ntchito. Njira zowunikira nthawi zonse ndi monga kumenya nyundo, kutulutsa, ndikugudubuza. Njira yopangira nyundo ndiyo nyundo chidutswa choyesera ndikuyang'ana pamwamba pa filimu yophimba. Konzani chidutswa choyesera kuti mupewe nsanja yothandizira nyundo yokhala ndi kutalika ndi msinkhu womwewo. Nyundoyo imakhazikika pa nsanja yothandizira, kotero kuti kulemera kwa chogwiriracho kumachepetsedwa mwachibadwa, ndipo mfundo za 5 zimagwedezeka mofanana pazigawo za 4mm. Yang'anani ngati filimu yapakhungu ikuphwanyidwa kuti iweruze.
Iyi ndi njira ya tsiku ndi tsiku yopangaunyolo ulalo mpandamankhwala.
