- ʻO ka 10,3 km Changtai Bridge e hele i ka Yangtze a hoʻohui i ke alanui a me ke kaʻaahi.
- ʻO ka lōʻihi nui o 1.208 m: ma mua o ka Russky Bridge (1.104 m).
- Nā mea hou: nā uwea tendon fiber carbon, nā lopako ma lalo o ka wai, a me nā cranes akamai.
- Hoʻouka i nā hoʻokolohua me nā kaʻa 110 a me ka mana hoʻolālā i haʻi ʻia o 530.000 tons.
Ua wehe ʻo Kina i ke kālepa ʻana i ka Ua alahaka ʻo Changtai, he hana mega i hoikeia e like me ka uwapo nui loa ma ka honua ma ka lōʻihi o ka papa a me ka lōʻihi nui, a ʻo ia ka mea e hoʻoikaika nui ai i ka pilina ma luna o ka muliwai Yangtze.
Aia ma ka moku ʻo Jiangsu, pili ka loulou Changzhou a me Taizhou me ke ano o 10,3 kilomita, he kiko waena o 1.208 mika a me na hale kiai o 350 mika kiʻekiʻe, nā mea a pau i kahi hoʻonohonoho multimodal e hui pū alanui a me ka hao.
He aha ka mea e hoʻolilo ai i ka Changtai i ke alahaka nui loa e noho ana i ke kaula?
ʻAʻole ia he alahaka hoʻokuʻu: ma kahi alahaka hoʻokuʻu ke kau ʻia ka papa nā uwea nui ma ka catenary; ma ka Changtai, o ke ano paʻa i ke kaula, ua paa pololei ka papa i na hale kiai ma o nā kaula hili, ka mea e wehewehe ai i kona ʻano hana a me kona ʻike ʻike.
Kona kukui nui o 1.208 mika haki i ka mooolelo alahaka Lukia ma Vladivostok (1.104 m) a hui pū me nā mea nui ʻē aʻe: ʻo ka Changtai he a alahaka ala-ala hui i loko o ke kila kila, me ka hoomau loa o ka lattice kaola i loko o kona waeʻano.
Me ka hoʻokō ʻana, ua hoʻemi nui ʻia ka manawa huakaʻi ma waena o nā panakō ʻelua o ka Yangtze: hele ka huakaʻi ʻoi aku ma mua o 80 mau minuke a ma kahi o 20, he lele e hooikaika ana i ka hana waiwai a ka neʻe ʻana i kēlā me kēia lā ma ka muliwai delta.
Aia ka hoʻolālā pae ʻelua, ma luna, a ala ala ʻeono (100 km/h) a, ma ka ʻaoʻao haʻahaʻa, kahi hoʻonohonoho asymmetrical i ʻike ʻole ʻia me kaʻaahi interurban ma 200 km/h ma ka ʻaoʻao o kahi alanui kūloko ʻehā (80 km/h), hoʻohui ʻia ʻaoʻao.
ʻenehana hana hou a me ka hana
ʻO ka hana, i hanaʻia i ka wā o ʻeono makahiki malalo o ke alakai ana a Ke Kūkulu ʻana o nā Kamaʻilio Kina, haʻalele i kekahi mau milestones: ʻo ka māmā holo kiʻekiʻe loa no nā hukihuki nui i loko o ka lepo lepo, ka mua akamai hale kiai crane me ka mana o ka 10.000 tonnes-mika a me ka holomua nā pylons huila kila hana ʻia ma kahi ʻano hana ʻenehana.
No ka manawa mua i hoʻohana ʻia i kēia ʻano hale nā ʻuʻuku kalapona no ka hana ʻana i nā kaula hoʻohuihui ikaika kiʻekiʻe, ʻaʻole maʻalahi i ka mahana a me ka hana ʻoi aku ka maikaʻi ka pala, hoʻonui i ka lōʻihi o ka ʻōnaehana bracing.
ʻO nā hale kiaʻi i ke ʻano o daimana, o 350 mika, hoʻohui ke kila a me ke kaʻa no ka hoʻomaikaʻi ʻana i ke kūpaʻa. ʻO kona mau kumu, hoʻoholo me nā caissons hoʻoikaika ʻia, ua hoʻolālā ʻia e kū i ka nā au ikaika o ka Yangtze; e like me ka mea i wehewehe ʻia e ka luna o ka papahana ʻo Li Zhen, ʻo ka paʻa "ma muli o ka pahu i lalo o ka wai."
ʻO ka asymmetry o ka papa haʻahaʻa he luʻi kaulike: ʻo ka hui ʻepekema nui Qin Shunquan hooponopono i ka hoʻopaʻapaʻa o nā kaula ma ka ʻaoʻao kaʻaahi e hoʻonui i ka hoʻokiʻekiʻe a, ma ke ʻano like, calibrated ka ke ʻano a me ke kaumaha o kēlā me kēia ʻāpana i hana mua ʻia, i ka wā i hāpai ʻia ai a hui ʻia, e pae ka hale.
I ka wā i hoʻokomo ʻia ai nā hana ma lalo o ka wai nā lopako akamai hiki ke hoʻokele i ka ʻāina paʻakikī a hoʻomaʻemaʻe i nā wahi wai, hoʻemi i nā hana luʻu. Eia hou, ka crane nui loa no nā papa alahaka o kona ʻano e hoʻonoho i nā ʻāpana nui me ka pololei millimeter.
Ka ho'āʻo, ka hiki a me ka laulā
ʻO ka hōʻoia hope loa me kahi hoʻāʻo me 110 mau kalaka y 4.400 tone hoouka like. Wahi a kona mau luna, hiki i ka hale ke lawelawe i a ka nui o 530.000 metric tons, hāʻawi i kahi palena palekana ma lalo o nā haʻahaʻa koʻikoʻi.
El ʻO Yangtze, me kekahi 6.300 km, ʻo ia ka muliwai lōʻihi loa ma ʻAsia a me kahi kikowaena logistical kī; i nā makahiki i hala iho nei ua hoʻonui ʻia ka nui o nā alahaka ma luna o kona ala mai ka ʻumi a ʻoi aku ʻoi aku ma mua o 150, a ke hoʻoikaika nei ka Changtai i kēia kaʻina hana o hoʻohui ʻāina ma Kina hikina.
No nā moʻolelo, paʻa ʻo Changtai i ka moʻolelo ma ka māhele noho uwea; no kona aoao, mawaena o na uwapo nā lei hōʻike i ka Huajiang Canyon ma Kina, me nā kiʻi koʻikoʻi o ke kiʻekiʻe a me ka māmā, ʻoiai ʻo ia no a ʻano hana like ʻole.
Me kona hui pū ʻana o māmā maikaʻi, ʻekolu kaʻa kaʻa a me nā mea hou maikaʻi, hoʻohui ke alahaka ʻo Changtai i kahi kūlana hou no nā kahe kahawai nui a lawe mai i kahi hoʻomaikaʻi maoli manawa, palekana a me ka hiki no ka neʻe ʻana o ka ʻāina ma Jiangsu.
He kanaka ʻenehana wau i hoʻololi i kāna mau makemake "geek" i ʻoihana. Ua hoʻohana au ma mua o 10 mau makahiki o koʻu ola me ka hoʻohana ʻana i ka ʻenehana ʻokiʻoki a me ka hoʻomaʻamaʻa ʻana i nā ʻano papahana āpau ma muli o ka ʻike maʻemaʻe. I kēia manawa ua loea wau i ka ʻenehana kamepiula a me nā pāʻani wikiō. ʻO kēia no ka mea ʻoi aku ma mua o 5 mau makahiki aʻu i kākau ai no nā pūnaewele like ʻole e pili ana i ka ʻenehana a me nā pāʻani wikiō, e hana ana i nā ʻatikala e ʻimi nei e hāʻawi iā ʻoe i ka ʻike āu e pono ai ma kahi ʻōlelo i hoʻomaopopo ʻia e nā mea a pau.
Inā he mau nīnau kāu, pili koʻu ʻike mai nā mea a pau e pili ana i ka ʻōnaehana hana Windows a me Android no nā kelepona paʻalima. A ʻo kaʻu hoʻohiki ʻana iā ʻoe, makemake mau wau e hoʻolilo i mau minuke a kōkua iā ʻoe e hoʻoholo i nā nīnau āu e loaʻa ai ma kēia ao pūnaewele.
