Hoʻohana ʻia ʻo Steel Strand Synchronous Hoisting System no ke kūkulu ʻana i ke kila kila o Guojiatuo Yangtze River Bridge

Aia ʻo Guojiatuo Yangtze River Bridge ma Nanʻan District a me Jiangbei District. He alahaka kaaahi lehulehu me ka lōʻihi o 1403.8 mika. ʻO ka hale kiaʻi ʻākau he 161.9 mika ke kiʻekiʻe, ʻo ka hale kiaʻi hema he 172.9 mika ke kiʻekiʻe, a ʻo ka lōʻihi nui he 720 mika. ʻO ka paʻa ʻana o ke alahaka e hoʻopili pū ʻia ʻo Liangjiang New District i ka māla kī. Ua hoʻopōkole ʻia ka manawa hoʻokele ma ia wahi mai 40 mau minuke a i 10 mau minuke. Ma ke ʻano he ʻāpana koʻikoʻi o nā laina kūʻokoʻa ʻeono" o Chongqing "ʻeono ākea a me ʻehiku kūpaʻa" ʻoihana hoʻokuʻu, ua hoʻolālā ʻia ka pae kiʻekiʻe o ka Guojiatuo Yangtze River Bridge me nā ala ʻelua ʻewalu ala, a ʻo ka pae haʻahaʻa ʻo ia ka laina kaʻaahi Line 8 Ua mālama ʻia ke kahawai ʻaʻa kahawai a manaʻo ʻia e hoʻopau ʻia i ʻOkakopa 2022.
Ma lalo mākou e hōʻike iā ʻoe i ke kaʻina hana hoʻonui hoʻonohonoho. ʻO ka mua, e lawe ka moku ukana ro-ro 2,000-ton i ka pahu kila mua o ke alahaka ʻo Guojiatuo Yangtze River a hiki i ka ʻili o ka muliwai ma lalo o ke kikowaena o ka nui o ke alahaka. Ma hope iho, ua hoʻokiʻekiʻe mālie ʻia ka pahu kila me ka lōʻihi o 20.5 mika, ka laulā o 39 mau mika, ke kiʻekiʻe o 12.7 mika a me ke kaumaha o 652 tons i hāpai ʻia e ʻelua mau pahu hoʻokiʻekiʻe synchronous me kahi hoʻolālā i helu ʻia he 800 tons. Ma hope o ʻekolu hola a me ka hapa o ka hoʻoikaika ʻana e nā limahana he 20, ua hoʻokomo pono ʻia ka pahu kila mua ma ka maʻa.
