Pehea e koho ai i nā ʻāpana o ke pou hōʻailona kaʻa

I ka wā e pili ana i ke koho ʻana i ka mea kūpononā pou hōʻailona kalepa, aia kekahi mau ʻano e noʻonoʻo ai. Loaʻa iā ʻoe kāunā pou kukui kalepa ʻewalu, nā pou kukui kaʻa conical, a menā pou kukui kaʻa huinahā, kēlā me kēia me ko lākou mau ikaika ponoʻī.Nā pou hōʻailona kalepa ʻewaluhe koho kaulana no nā huina alanui maʻamau no ka mea hiki iā lākou ke hoʻokele like i ke kaumaha a he ʻano maʻemaʻe a symmetrical.Nā pou hōʻailona kalepa conical, ma ka ʻaoʻao ʻē aʻe, he ʻano nani ko lākou a hoʻohana pinepine ʻia ma nā alanui nani a i ʻole nā ​​​​alanui nui o nā kūlanakauhale.Nā pou huinahāHe ikaika loa lākou a hiki ke lawelawe i nā ukana kaumaha, e kūpono ana iā lākou no nā intersection nui me nā kukui uila a me nā lako he nui. A laila aia kēia mau kiʻi gantry i hoʻohui ʻia, e like me ka hopena hope loa no nā intersection nui, multi-lane - hiki iā lākou ke paʻa i nā set he nui o nā kukui uila a me nā mea nānā i ka manawa hoʻokahi. No laila, no ka ʻike ʻana i ke ʻano o ka pou āu e pono ai, pono mua ʻoe e hoʻoholo i kona ʻano kūkulu. E kōkua kēia iā ʻoe e hoʻoholo i ka mea maikaʻi loa no kou kūlana kikoʻī. Inā ʻoe e hana nei me kahi intersection paʻahana a i ʻole ke alanui hiʻohiʻona, ʻo ke koho ʻana i nā pou kukui uila kūpono he mea nui ia no ka palekana a me ka pono. Ma ka noʻonoʻo ʻana i nā ʻano pou like ʻole a me ko lākou ʻano, hiki iā ʻoe ke hoʻoholo i kahi hoʻoholo naʻauao a loaʻa nā lako kūpono no ka hana.

I ka wā e pili ana i ke koho ʻana i ka mea kūponoka lōʻihi o ke cantilever, he ʻāpana koʻikoʻi ia o ke kaʻina hana. He kuleana nui ka helu o nā ala ma ke alanui i ka hoʻoholo ʻana i ka lōʻihi o ke cantilever. No ka laʻana, inā ʻoe e hana nei me kahialanui ʻelua ala, heka lōʻihi o ke cantilever o 3-5 mikahe koho maikaʻi maʻamau. Ma ka ʻaoʻao ʻē aʻe, inā ʻoe e hana pū ana me kahialanui ʻehā alahele, makemake pinepine ʻoe e hele me kahika lōʻihi o ke cantilever he 6-8 mikaA no nā alanui nui meʻeono a ʻoi aku paha nā alahele, heka lōʻihi o 9-12 mikapinepine ʻia. Akā eia ka mea: inā ʻoe e hana i ka cantilever i lōʻihi loa, hiki ke hana i nā pilikia. Hoʻonui ka manawa kūlou o ke pou, ʻo ia hoʻi, pono ʻoe e hoʻomānoanoa i ka paia paipu e pale aku ai i ka kūlou ʻana a me ke ʻano ʻē i ka hala ʻana o ka manawa. He mea nui hoʻi e hōʻoia i ka lawa ʻana o ka mamao palekana e mālama pono i nā kukui kaʻa ma luna o ke alahele, me ka ʻole o nā mea keakea e like me nā lāʻau a i ʻole nā ​​overpass e komo ana i ke ala. He mea nui kēia no ka hōʻoia ʻana e holo pono a palekana nā mea āpau. No laila, ke helu nei ʻoe i ka lōʻihi o ka cantilever, pono ʻoe e noʻonoʻo i kēia mau mea āpau. ʻAʻole ia e pili ana i ka paʻi ʻana i kekahi mau kukui kaʻa a kāhea aku iā ia i kahi lā - pono ʻoe e noʻonoʻo pono e pili ana i nā kikoʻī o ke alanui a me ke kaʻa e hoʻohana ana. Ma ka hana ʻana pēlā, hiki iā ʻoe ke hana i kahi ʻōnaehana palekana a maikaʻi hoʻi e hana maikaʻi no nā mea āpau.

ʻO nā mea i hana ʻia ai nā pou a me ke ʻano o ko lākou pale ʻia ʻana mai ka popo he mea nui ia i ka lōʻihi o ko lākou mau lā. ʻO ka maʻamau, hana ʻia nā pou hōʻailona kaʻa me kahi ʻano kila i kapa ʻiaQ235, a ua pale ʻia lākou me kahi kaʻina hana i kapa ʻiaka hoʻoheheʻe ʻana i ka wela, a i ʻole i kekahi manawa ua ukali ʻia e kahi papa pale ʻē aʻe i kapa ʻiauhi pauka electrostaticAkā ma nā wahi kokoke i ke kai a i ʻole nā ​​muliwai, kahi i paʻakai ai ka ea a hiki ke hōʻino i nā pou, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ʻelua papa o ka pale -ka hoʻoheheʻe ʻana i ka welaa meuhi pauka– e pale aku iā lākou mai ka popo ʻana. Ma nā kūlanakauhale ma uka aku, ua lawa ka papa hoʻokahi o ka galvanizing wela. ʻO ka mea, ʻo nā pou hōʻailona kaʻa e waiho mau ana ma waho, e ua ana a waiho ana i ka lā, e hoʻomaka e popo inā ʻaʻole lākou i pale pono ʻia, a he pilikia palekana paha ia. No laila, he mea nui loa ka hoʻohana ʻana i nā mea kūpono a me nā ʻano palekana e hōʻoia i ka lōʻihi o ke ola o nā pou a noho palekana.

ʻAʻole hiki ke hoʻowahāwahā ʻia nā kūlana ukana kaiapuni. Loaʻa i nā ʻāpana like ʻole nā ​​​​koi kikoʻī noke kū'ē ʻana i ka makani. Hoʻokō nā wahi pāpū i kahi kūlana pale makani o27 m/s, ʻoiai nā wahi i maʻalahi i ka typhoon e koi ana i kahi kūlana o36 m/sa ʻoi aku paha. I ke kau ʻana i nā hāmeʻa he nui, pono e helu ʻia ke kaumaha holoʻokoʻa o nā kukui uila, nā kāmela, a me nā hale e pale aku ai i ka hoʻouka nui ʻana. Pono hoʻi ke kahua e kūlike me nā pou; pono nā pou cantilever kiʻekiʻe i nā ʻōwili heleuma nui a me nā kumu sima.

I ke kau ʻana i nā kukui uila, nui nā mea e noʻonoʻo ai. ʻAʻole wale nā ​​lula, akā pehea hoʻi ko lākou ʻano. No ka laʻana, ma nā kūlanakauhale liʻiliʻi, hiki iā ʻoe ke kau wale iā lākou ma nā paia. Akā ma nā kūlanakauhale nui, pono e kūlike nā pou hōʻailona uila me ke ʻano a me ke kala o ke kūlanakauhale. Ma muli o nā alakaʻi koʻikoʻi ke kaʻina holoʻokoʻa e hōʻoia i ka palekana a me ka hana maikaʻi o nā mea āpau. ʻAʻole lākou e hoʻohana i nā pou lahilahi loa a i ʻole ʻaʻole i kūlike i nā kūlana. ʻO ka pahuhopu ke koho i nā pou kukui uila e hana i kā lākou hana a mau loa, no laila ʻaʻole pono ʻoe e hoʻolilo i ke kālā he nui e hoʻoponopono iā lākou ma hope. Ma kēia ʻano, e neʻe mālie a palekana ke kaʻa.

Qixianghana i nā ʻano āpaunā pou kukui kaʻa, e like me ke ʻano octagonal, nā mea conical, a me nā mea nuinā pou gantryHana ʻia kā mākou mau pou hōʻailona kalepa mai nā mea ikaikaQ235 kilaa pale mākou iā lākou mai ka ʻōpala me kahi mea kūikawāka hoʻoheheʻe ʻana i ka welaa me ke kaʻina hana uhi pauka. Inā makemake ʻoe i kahi pou hōʻailona kaʻa me kahi lōʻihi lima a makemake paha e hiki ke kū i nā makani ikaika, hiki iā mākou ke hana i kēlā. He nui nā nui a me nā ʻano like ʻole, a ua kūkulu ʻia kā mākou mau pou e mau. Hiki iā ʻoe ke loaʻa iā lākou me nā ʻōwili heleuma no ka palekana hou aku. Inā ʻoe e ʻimi nei i nā pou hōʻailona kaʻa maikaʻi, e haʻi wale mai iā mākou i kāu mea e pono ai a na mākou e mālama iā ʻoe - makemake mākou e hāʻawi i nā hopena maikaʻi loa no nā alanui.
