Chotchinga cha W beam galvanized cha liwiro lalikulu ndicho chotchinga chodziwika bwino cha ngozi za pamsewu chomwe chimapangidwa kuti chilepheretse galimoto kutuluka mumsewu pamalo oopsa.
Choteteza cha Thrie beam (three beam) chili ndi mphamvu yabwino yoletsa ngozi, yomwe imagwiritsidwa ntchito kwambiri m'misewu yoopsa monga misewu yapamwamba komanso mlatho.
Matabwawo amamatiridwa ndi zinc kapena zinc + pulasitiki kuti apewe malo ofooka omwe amayamba chifukwa cha dzimbiri ndi dzimbiri.
Timapanga zotchingira misewu motsatira miyezo iyi:
A. GB/T31439-2015 (Mizati ya Zitsulo Zopangidwa ndi Corrugated Sheet for Expressway Guardrail - China)
B. AASHTO-M180 (Mizati ya Zitsulo Zopangidwa ndi Zitsulo Zoteteza Msewu Waukulu - USA)
C. AS/NZS 3845:1999 (Machitidwe Oletsa Chitetezo cha Msewu - Australia/New Zealand)
D. EN-1317 (Machitidwe Oletsa Misewu - Europe)
E. Kapena kupanga zinthu mogwirizana ndi zosowa za kasitomala
1) Kukula Koyenera: 4320mm*506mm*85mm, 3820mm*506mm*85mm, 3320mm*506mm*85mm, 2820mm*506mm*85mm, 2320mm*506mm*85mm, kapena malinga ndi zomwe makasitomala amafuna.
2) Zipangizo: S235, S275, S355, kapena malinga ndi zosowa za makasitomala
3) Makulidwe achitsulo oyambira: 3mm, 4mm, kapena malinga ndi zosowa za makasitomala
4) Chithandizo cha pamwamba: Kuviika kotentha kokhala ndi ma galvanized
5) Kukhuthala kwa zinki: 600g/m2, 84 um, kapena malinga ndi zosowa za makasitomala
6) Miyezo: GB/T31439.2-2015
7) Kugwiritsa Ntchito: Msewu Waukulu, Misewu Yapamwamba.
Choteteza cha liwiro lalikulu chimayamwa mphamvu ya kugundana pogwiritsa ntchito kusintha kwa maziko a nthaka, mzati ndi denga, ndipo chimakakamiza magalimoto othawa kuti asinthe njira ndikubwerera ku njira yabwino yoyendetsera, motero amaletsa magalimoto kutuluka mumsewu mwachangu, kuteteza magalimoto ndi okwera ndikuchepetsa kutayika komwe kumachitika chifukwa cha ngozi.
Magalasi oteteza a W beam yothamanga kwambiri amagwiritsidwa ntchito kwambiri m'mapulojekiti a Highway Guardrails. Magalasi oteteza a W beam yothamanga kwambiri amayamwa mphamvu yogundana pogwiritsa ntchito kusintha kwa maziko a nthaka, mzati ndi mzati, ndipo amakakamiza magalimoto othawa kuti asinthe njira ndikubwerera ku njira yabwino yoyendetsera, motero amaletsa magalimoto kutuluka mumsewu mwachangu, kuteteza magalimoto ndi okwera ndikuchepetsa kutayika komwe kumachitika chifukwa cha ngozi.
Kugwiritsa ntchito
Monga makampani otsogola mumakampani opanga zinthu zachitsulo ku China, malonda achitsulo ndi zinthu zamtundu wa "Zana la bizinesi yabwino", makampani ogulitsa zitsulo ku China, "Mabizinesi 100 apamwamba kwambiri ku Shanghai". Shanghai Zhanzhi industry Group Co., Ltd., (yofupikitsidwa ku Zhanzhi Group) imatenga "Umphumphu, Kuchita Zinthu Mwanzeru, Kupanga Zinthu Mwatsopano, Kupambana" ngati mfundo yokhayo yogwirira ntchito, nthawi zonse imapitiliza kuyika zofuna za makasitomala pamalo oyamba.
