Kupititsa patsogolo Zida Zamagetsi Zachilengedwe Zokhala Ndi Machubu Akuluakulu Owotcherera: Ubwino Wa S235 J0 Spiral Steel Pipes
Gawo 1: Kufotokozera mwatsatanetsatane kwa chubu chachitsulo cha S235 J0
S235 J0 chitoliro chachitsulo chozungulirandi chitoliro chachikulu chowotcherera m'mimba mwake chokhala ndi umphumphu wabwino kwambiri komanso kukana dzimbiri.Mapaipiwa amapangidwa pogwiritsa ntchito ukadaulo wapamwamba pogwiritsa ntchito njira yapadera yowotcherera yozungulira kuti ikhale yolimba, yofananira komanso yopanda msoko.Kuphatikiza apo, amatha kusinthidwa kuti akwaniritse zofunikira za projekiti molingana ndi mainchesi, makulidwe, ndi kutalika.

Gawo 2: Ubwino wa mipope yayikulu yowotcherera.
2.1 Mphamvu zowonjezera komanso kulimba:
Large awiri welded chitoliros, kuphatikizapo S235 J0 chitoliro chachitsulo chozungulira, chimapereka mphamvu zapamwamba komanso zolimba.Chifukwa chaukadaulo wazowotcherera, mapaipiwa amatha kupirira mphamvu zambiri zakunja, monga kuthamanga kwa nthaka, kuchuluka kwa magalimoto ndi zochitika zachivomezi, popanda kusokoneza kukhulupirika kwawo.Kulimba mtima kumeneku kumapangitsa moyo wautali wautumiki ndipo kumachepetsa kwambiri ndalama zolipirira zomwe zimagwirizanitsidwa ndi kupanga mapaipi achilengedwe.
2.2 Kukana kwa Corrosion:
Kuwonongeka ndi vuto lalikulu pamayendedwe a gasi chifukwa amatha kusokoneza kukhulupirika kwa mapaipi ndikuyambitsa kutayikira kapena kuphulika.S235 J0 ozungulira zitsulo chitoliro ali ndi wosanjikiza zoteteza, kawirikawiri zopangidwa epoxy utomoni, amene amapereka kukana kwambiri dzimbiri mkati ndi kunja.Kusamala kumeneku kumateteza kusamalidwa bwino kwa mapaipi ndikuwonetsetsa kuyenda kwanthawi yayitali kwa gasi wachilengedwe.
2.3 Kutsika mtengo:
Poganizira kukhazikika kwake komanso zofunikira zochepa zosamalira, chitoliro chachikulu chowotcherera chozungulira chimatha kupulumutsa ndalama zambiri pakapita nthawi.Kuchepetsa kukonzanso, kusinthidwa ndi nthawi yocheperako kumapereka phindu lalikulu pazachuma kwa ogwiritsa ntchito gasi wachilengedwe.Kuonjezera apo, mphamvu zawo zamphamvu kwambiri zimalola nyumba zokhala ndi mipanda yopyapyala popanda kusokoneza chitetezo, motero kuchepetsa ndalama zakuthupi panthawi yomanga.
2.4 Kuyika bwino:
Mapaipi akulu akulu otchingidwa, monga mapaipi achitsulo a S235 J0, ali ndi maubwino apadera pakuyika.Ndi zopepuka kulemera kuposa konkriti wamba kapena mapaipi achitsulo, kufewetsa zoyendera ndi kagwiridwe ka malo.Kuphatikiza apo, kusinthasintha kwa spiral chubu kumapangitsa njira yolowera kukhala yosavuta, ngakhale m'malo ovuta.Zotsatira zake, mapaipiwa amathandizira kumaliza ntchito mwachangu komanso kotsika mtengo ndikuwonetsetsa kuti ntchitoyo ikuyenda bwino.
Pomaliza:
M'nthawi ino ya kuchulukirachulukira kwa gasi wachilengedwe, kuwonetsetsa kudalirika ndi chitetezo chazomwe zimapangidwira gasi ndikofunikira.Pogwiritsa ntchito chitoliro chachikulu chowotcherera, makamaka S235 J0 chitoliro chachitsulo chozungulira, oyendetsa mapaipi amatha kupindula ndi mphamvu zowonjezera, kukana dzimbiri, kutsika mtengo komanso kuyika bwino.Mapaipiwa amapereka njira yothetsera nthawi yayitali yomwe imaphatikiza kulimba ndi kusinthika ku zofunikira zosiyanasiyana za polojekiti, zomwe zimapangitsa kuti pakhale njira yotetezeka, yodalirika komanso yotsika mtengo yapaipi ya gasi.
