Nkhani - Makina Opangira Mapepala Achitsulo Apamwamba Athandiza Kupititsa Patsogolo Ntchito za Mlatho wa Sitima Yapamtunda Padziko Lonse

Chipinda chapamwamba chamulu wa pepala lachitsulomakina tsopano akuthandiza kumanga mlatho mwachangu pa njanji yothamanga kwambiri pamapulojekiti akuluakulu angapo ku North America, Latin America ndi Asia. Malipoti a uinjiniya akuwonetsa kuti yankho lolimbikitsidwa kutengera chitsulo champhamvu kwambiri, njira zoyikira modular komanso chitetezo chabwino cha dzimbiri zimathandiza kuchepetsa kwambiri nthawi yomanga maziko, pomwe akuwonjezera kukhazikika kwa kapangidwe kake kwa nthawi yayitali.

Kugwiritsa Ntchito Mulu wa U Steel Sheet

Oyang'anira polojekitiyi pa msewu wa sitima yapamtunda wothamanga kwambiri ku US West Coast akuti ntchitoyi ndi yapamwamba kwambirimulu wa pepalaDongosololi limafulumizitsa ntchito yomanga nyumba ya cofferdam, limachepetsa kufunika kwa zida zolemera, komanso limawonjezera chitetezo m'nthaka yofewa komanso yodzaza ndi madzi. Ukadaulo uwu umathandiza kuti nthaka ikhale yozama komanso kuti ikule bwino mbali zake, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pa matabwa a mlatho ndi ma abbot m'malo ovuta.

Ku Mexico ndi Chile, komwe ntchito zingapo zatsopano zoyendera njanji pakati pa mizinda zikuyamba, makontrakitala akuwonetsa kuti njira yatsopanoyiLembani mulu wa pepalaYankho lake limapereka njira yosungira nthaka yotsika mtengo, limathandizira kufukula mwachangu, ndipo limapereka njira ina yabwino kwambiri yotetezera chilengedwe m'malo mwa makoma osungira konkire olimbikitsidwa. Kugwiritsa ntchito kwakenso kumachepetsanso zinyalala ndi mpweya woipa womwe umachokera ku ntchito yonse.

Kuwonjezeka kwakukulu kumachitika chifukwa chogwiritsa ntchito zitsulo zolimba kwambiri zomwe zimagwirizana ndi miyezo ya ASTM/AASHTO, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito.mulu wachitsulo wopangidwa ndi ukuti akumane ndi mavuto aakulu omwe amayembekezeredwa mu sitima yothamanga kwambiri. Zophimba zabwino zolimbana ndi dzimbiri zimawonjezeranso moyo wa ntchito ya maziko zomwe zimapangitsa kuti milatho ya sitima ikhale yokhazikika kwa nthawi yayitali yomwe imapangidwira ntchito ya zaka 80-100.

Njira Zoyenera Zokhazikitsira Mulu wa Mapepala Oyenera-1200x900_

Akuluakulu ochokera ku maunduna osiyanasiyana oyendetsa mayendedwe akuti njira yotsogola idzakhala yofunika kwambiri pakukulitsa njanji yapamtunda yapamtunda mtsogolo. Pamene ndalama zoyendetsera zomangamanga padziko lonse lapansi zikuyang'ana kwambiri pakuyenda mwachangu komanso njira yomangira yobiriwira, njira yopangira matabwa achitsulo yogwira ntchito bwino idzakhala muyezo wopanga milatho yatsopano ya sitima.

Pamene mayiko akuthamanga kuti amange njira zamakono zoyendera njanji zamtundu wa high speed, ukadaulo wotsogola uwu wa maziko achitsulo udzasintha kwambiri ntchito yomanga mapulojekiti akuluakulu a milatho, kupititsa patsogolo ntchito zogwirira ntchito komanso kupereka milatho yolimba komanso njira zokhazikika kwa mibadwo ya omanga zomangamanga.
