Machubu Olimba a Chitsulo Chomangidwa ndi Kapangidwe kake a Megaprojects Amakono
Pakukula kwa zomangamanga padziko lonse lapansi, ogulitsa mapaipi achitsulo padziko lonse lapansi akukumana ndi kufunikira kwakukulu kwa ma profiles akuluakulu. Pamene mapulojekiti akuluakulu monga nyumba zazitali, nyumba zamabwalo amasewera, ndi maziko amphepo akunyanja akupitilira kukula, magawo wamba okhala ndi malo ozungulira monga 400×400 mm kapena 500×500 mm sakukwaniranso kukwaniritsa zofunikira za kapangidwe kake. Kwa mainjiniya omanga omwe amapereka Pempho la Mtengo, kukonza modulus yopingasa pomwe kuwongolera kulemera konse kwachitsulo ndi vuto losatha. Pothana ndi katundu wolemera kwambiri wa axial ndi nthawi zovuta zopindika,chitoliro cholemera cha khoma lalikulundi zigawo zazikulu zamakona anayi (SHS/RHS) amapereka luso losayerekezeka la kapangidwe kake poyerekeza ndi matabwa otseguka wamba kapena mbale zolumikizidwa.
Zofooka za Kulumikiza Kwachikhalidwe ndi Kupanga Chitoliro cha Chitsulo cha LSAW
Pamene mapangidwe a nyumba zapadera amafuna zigawo zazikulu zopanda kanthu zopitirira 1000 mm, madipatimenti ogula zinthu nthawi zambiri amakumana ndi zovuta zopanga. M'madera ambiri padziko lonse lapansi, makontrakitala amakakamizidwa kulumikiza mbale zinayi zachitsulo pamanja m'magawo a mabokosi omangidwa pamalopo, kapena kuphatikiza machubu ang'onoang'ono angapo kukhala ma trus ovuta. Kupanga kumeneku kumafuna kulumikiza munda wolemera, kukulitsa ndalama zogwirira ntchito ndikuwonjezera nthawi yoyesera yosawononga. Kuphatikiza apo, mipata yolimba ya munda wothira imabweretsa chiopsezo cha kutopa kwa nthawi yayitali. Ngakhale kuti khoma lolemera ndi lolemera.LSAWChitoliro chachitsulo ndi chodalirika kwambiri potumiza madzi, kusintha mawonekedwe ozungulira kukhala chubu chachikulu cha sikweya kumafuna luso lalikulu la mafakitale lomwe mafakitale ochepa padziko lonse ali nalo.
Kuswa Malire a Kukula ndi Zigawo za 1550 x 1550 x 80 mm Zokhala ndi Mphepo Yaikulu
Pofuna kuthetsa kusiyana kwakukulu kumeneku, Yuantai Derun yasintha kapangidwe kake ka mapaipi olemera achitsulo. Yuantai Derun yapitirira malire a njira zachikhalidwe zopangira ozizira. Kampaniyo tsopano ikhoza kupanga magawo okwana sikweya imodzi okhala ndi kukula mpaka 1550 × 1550 mm ndi makulidwe a makoma okwana 80 mm. Ma profiles akuluakulu a SHS ndi RHS awa amapatsa ogula njira yodalirika yopangidwa ndi fakitale, kuchepetsa kufunikira kowotcherera pamalopo ndikupangitsa kukhazikitsa ndi kugwiritsa ntchito zinthu kukhala kogwira mtima kwambiri.
Ndondomeko ya Uinjiniya: JCOE ndi Ukadaulo Wozungulira mpaka Pachikwere
Kupanga bwino chitoliro cha sikweya cha makulidwe a khoma la 80 mm kumafuna njira yatsopano yopangira.Yuantai DerunImasiya kupanga mozungulira mozungulira mozungulira mwa kuphatikiza njira yopangira JCOE yolemera ndi ukadaulo wapamwamba wa Round-to-Square. Choyamba mbaleyo imakanikizidwa pang'onopang'ono kukhala mbiri yozungulira yowongoka bwino pogwiritsa ntchito zida za JCOE zokhala ndi matani ambiri komanso kulowetsa Arc Welding yokhala ndi mbali ziwiri. Chubu chozungulira chokhuthala kwambiri chimapangidwa pang'onopang'ono kukhala mawonekedwe a sikweya kapena amakona anayi pogwiritsa ntchito njira yopangira mozungulira yolondola. Njira yopangira pang'onopang'ono iyi imathandiza kugawa kupsinjika mofanana pa chitolirocho, kuchepetsa chiopsezo cha ming'alu ya ngodya ndikupewa kusweka m'mbali.
Chitsimikizo cha Ubwino: Miyezo ndi Kutsimikizira
Pazigawo zolemera zomwe zimagwiritsidwa ntchito m'makina onyamula katundu, kuwongolera bwino khalidwe ndi kutsata bwino zinthu ndikofunikira. Pambuyo popanga ndi kuwotcherera, gawo lililonse la 1550 mm limadutsa mu njira yowongolera kutentha pambuyo pa kuwotcherera. Gawoli limathandiza kukonza kapangidwe ka mkati mwa chitsulo ndikuchotsa kupsinjika kwakukulu kotsalira kuchokera pakupanga, kukonza kukhazikika kwa mawonekedwe ndikuchepetsa chiopsezo cha kusweka komwe kumabwera chifukwa cha haidrojeni.
Njira yopangirayi ikuphatikizapo kuyesa kwa ultrasound ndi x-ray komwe kumachitika zokha kuti muwone bwino mipata yolumikizira. Mapaipi awa akukwaniritsa muyezo waposachedwa wa GB/T 6728-2025 ndipo adapangidwa kuti agwirizane ndi magiredi apadziko lonse lapansi monga EN 10210 S355J2H ndi ASTM A500 Giredi B/C, kuonetsetsa kuti mphamvu zake ndi magwiridwe antchito abwino kutentha kochepa. Gulu lililonse limabwera ndi Chitsimikizo cha Mill Test ndi kutsimikizira kwa QR code, zomwe zimapatsa ogula ndi magulu a mainjiniya mwayi wotsatira bwino komanso chidaliro mu mtundu wa malonda pamapulojekiti ofunikira.
