ʻO nā Bridges he mea hoʻoikaika koʻikoʻi i ka mōʻaukala kanaka. Mai nā wā kahiko i ka wā e hoʻohana ai nā kānaka i nā lāʻau holoi holoi a hoʻopaʻaʻia i nā alaloa a me nā mea kūʻai aku, i ka hoʻohanaʻana o nā mea kūʻai aku. ʻO ka weheʻana o ka Hong Kong Kong Kong-Zhuhai Bridget hōʻailona hōʻailona i kahi pōʻino ma ka mōʻaukala o nā alanui. I loko o ka hanaʻana i kēia manawa hana, ma kahi o ka hoʻohanaʻana i nāʻano hana paʻa, nā mea hao, nā mea koho nui loa ma muli o ko lākou mau mea likeʻole.
I ka makahiki 1933, ua hoʻohana muaʻiaʻo Alumun Alloy Bridge Deck ma kahi o ke alahaka ma kahi o ke alanui ma kahi kahawai i kahi kahawai i loko o nā moku'āina iʻAmelika Hui PūʻIa. ʻOi aku ma mua o nā makahiki heʻumi ma hope mai, i ka makahiki 1949,ʻo Kanada e hoʻopau i kahi kahawai nui a Alminum ʻO kēia alahaka i ke ao holoʻokoʻa o ka honua a Allumini alloy. Ua loaʻa i nā mea kīwī ma kahi o 15 mau mika kiʻekiʻe a me nā alanuiʻelua aʻelua no ke kaʻa kaʻa. Ua hoʻohanaʻiaʻo 2014-T6 aluminim alloy a loaʻa i kahi paona o 163 tons. Ua hoʻohālikelikeʻia i ke ala kila kila i hoʻolālā muaʻia, ua hoʻemi ia i ka momona ma kahi o 56%.
Mai laila,ʻaʻole i loaʻa ka heleʻana o ka heleʻana o Aluminum Allot i nā Bridgent alanui. Ma waena o 1949 a me 1985, ua kūkuluʻia ke aupuni hui ma kahi o 3550 a me ka makahiki o keʻano he 2050 a me 1970.
Ua hoʻohālikelikeʻia i ke kila, alumini alloy a me nā mea haʻahaʻa haʻahaʻa, e hana ana iā lākou i ka māmā nui, me ka 34% o ke kaupaonaʻana o ke kila. Eia naʻe, loaʻa iā lākou nā hiʻohiʻona ikaika e like me ke kila. Hoʻohui houʻia, Alumini Alloys Exhibit i ka Elasticity maikaʻi loa a me ke kū'ēʻana i ke kauʻana i ka wā o ka mālamaʻana i nā uku mālama. Ma muli o kahi hopena, ua loaʻa iā lākou kahi noi nui i loko o ke kūkuluʻana i kēia manawaʻo Bridge Course.
Ua hana nuiʻo Kina i nā alakaʻi nui ma ke alakaʻi aʻoʻana. ʻO ke alaʻo Zhaizhou, e kū ana no nā makahiki 1500,ʻo ia kekahi o nā mea hoʻokō o nā kaukani Kina kahiko. I ke kaʻa hoʻokipa: me ke kōkua o ka nui o ka Soviet,ʻo Kanawa i kūkuluʻia i kahi o ke kīwī o Galjing ma NaNJingzhou. Eia nō naʻe,ʻo ka noiʻana o ka noiʻana a Alminim alloy gridges ma Kina e like me ka palena o Kina. ʻO ka Luna Nui Mua muaʻo Alloninum I ka makahiki hoʻokahi,ʻo ke alahaka o ka wāwae ma Xujhiali, ua kūkuluʻiaʻo Shanghai Ua hoʻohana muaʻiaʻo 6061-T6 alumlunim alloy a,ʻoiai i kona paona 15-ton.
I ka wā e hiki mai ana, aluminum alloy bigdges e loaʻa ana i nā mea kūʻai aku ma Kina no kekahi mau kumu:
1ʻO ke kūkuluʻana o ka Renal-Speed Rail Stail,ʻoi aku ka nui o nā'āina paʻakikī o nā'āina o nā mokupuni a me nā kahawai nui a me nā kahawai. ʻO Aluminum Alloy Gridged
ʻO nā mea kūʻai aku 2 e hoʻopaʻaʻia i ka holoʻana a loaʻa ka hana maikaʻi i nā haʻahaʻa haʻahaʻa. ʻO ka corrosioni o ke kilokilo nui e pili ana i keʻano o ke alahaka, e hopena ana i nā uku uku kiʻekiʻe a me nā pilikia palekana. I ka hoʻohālikelikeʻana, ua loaʻa nā waiwai a Alminim alloy a me ka hana ma nā kūlana haʻahaʻa, e hana ana i nā kūlana lōʻihi a me ka hoʻonuiʻana i nā kūlana lōʻihi. ʻOiai eʻoi aku ka nui o nā kumu kulanui allonunim alloy i nā kumukūʻai kiʻekiʻe, hiki i ko lākou uku hoʻolimalima haʻahaʻa e kōkua i ka hōʻemiʻana i ke kumukūʻai kumukūʻai ma mua.
3ʻO ka noiʻiʻana ma nā papa kuhikuhi a Aluminim Hoʻomaopopo i nā holomua ma ka noiʻi noiʻi no ka hōʻoiaʻana i nā mea kōkua hou e hoʻokō i nā pono hana likeʻole. Nā mea hana Alminimum, e pili ana i nāʻoihana kanaka e like me ka mea e like me ka laweʻana i nā mea hana Alumini almuinum a aeminum Alulunum alulus i kūkuluʻia i ke kūkuluʻiaʻana o kaʻoihana Aluminum
4ʻO ke kūkuluʻana i nā hale kūʻaiʻo Guid Tirbad ma nā kūlanakauhale nui o nā Kina i hāʻawiʻia no nā koiʻana o nā koina ma luna o ka'āina ma luna o ka lepo. Ma muli o kā lākou waiwai koʻikoʻi nui, he mau mea nui ia e hana houʻia a me nā ala kiʻekiʻe a Alluintrian a hoʻohanaʻia i ka wā e hiki mai ana.
I hoʻoponoponoʻia e ka jiang mai ka alumini
