Me pēhea te whiriwhiri i ngā wāhanga o te pou tohu huarahi

Ina tae ki te whiriwhiri i te mea tikangā pou tohu huarahi, he iti noa ngā momo hei whakaaroaro. Kei a koe tāungā pou rama waka waru-ā-toru, ngā pou rama waka kōniko, mengā pou rama huarahi tapawhā, he rerekē ngā kaha o ia tangata, o ia tangata.Ngā pou tohu huarahi waru-ā-toruHe kōwhiringa rongonui mō ngā whakawhitinga huarahi noa nā te mea ka taea e rātou te whakahaere i te taumahatanga kia ōrite, ā, he ātaahua, he ōrite hoki te āhua.Ngā pou tohu huarahi kōniko, i tētahi atu ringa, he ātaahua te āhua, ā, e whakamahia ana i ngā rori ataahua, i ngā tiriti matua rānei o ngā tāone.Ngā pou tapawhāHe tino kaha, ā, ka taea te whakahaere i ngā kawenga taumaha, he mea tino pai mō ngā whakawhiti huarahi nui me te maha o ngā rama huarahi me ngā taputapu. Kātahi ka tae mai ēnei anga gantry whakauru, he rite ki te otinga tino pai mō ngā whakawhiti huarahi nui, maha-ara - ka taea e rātou te pupuri i ngā huinga rama huarahi maha me ngā taputapu aroturuki i te wā kotahi. Nō reira, hei whakatau i te momo pou e hiahiatia ana e koe, me whakatau tuatahi koe i tōna momo hanganga. Mā tēnei ka āwhina i a koe ki te whakatau ko tēhea te mea pai mō tō āhuatanga motuhake. Ahakoa kei te mahi koe i tētahi whakawhiti huarahi pukumahi, i tētahi rori ataahua rānei, he mea nui te whiriwhiri i ngā pou rama huarahi tika mō te haumaru me te whai huatanga. Mā te whakaaro ki ngā momo pou rerekē me ō rātou āhuatanga, ka taea e koe te whakatau whai whakaaro me te tiki i ngā taputapu tika mō te mahi.

Ina tae ki te whiriwhiri i te mea tikate roa o te cantilever, he wāhanga nui o te tukanga. He mea nui te maha o ngā ara i runga i te rori ki te whakatau i te roa o te cantilever. Hei tauira, ki te mea kei te mahi koe me tētahirori e rua ngā ara, hete roa o te cantilever 3-5 mitahe kōwhiringa pai i te nuinga o te wā. I tētahi atu ringa, ki te mea kei te mahi koe me tētahirori whā-ara, ko te tikanga ka hiahia koe ki te haere me tete roa o te cantilever he 6-8 mita. Ā, mō ngā rori matua mee ono, neke atu rānei ngā ara, hete roa o te 9-12 mitahe mea e taunakitia ana. Engari koinei te mea: ki te roa rawa te whakapūtanga o te pou, ka raru pea. Ka piki ake te piko o te pou, ko te tikanga me whakamātotoru te pakitara o te paipa kia kore ai e piko, e memeha haere rānei i te roanga o te wā. He mea nui hoki kia whakarite kia nui te tawhiti haumaru hei pupuri i ngā rama huarahi ki runga ake i te ara, me te kore he arai pēnei i ngā rākau, i ngā arawhata rānei e arai ana. He mea nui tēnei hei whakarite kia pai te oma me te haumaru o ngā mea katoa. Nō reira, i a koe e tatau ana i te roa o te pou, me whai whakaaro koe ki ēnei āhuatanga katoa. Ehara i te mea ko te patupatu noa i ētahi rama huarahi me te whakamutu – me whakaaro pai koe ki ngā āhuatanga motuhake o te huarahi me te hunga e whakamahi ana. Mā te mahi pera, ka taea e koe te hanga i tētahi pūnaha haumaru me te whai hua e pai ana mō te katoa.

He mea nui te roa o te ora o ngā pou me te āhua o te tiaki i a rātou mai i te waikura. I te nuinga o te wā, he momo maitai te mea hanga o ngā pou tohu huarahi e kiia nei koQ235, ā, ka tiakina rātou e tētahi tukanga e kiia nei kowhakapūmau wera-tō, i ētahi wā ka whai mai tētahi atu paparanga tiaki e kiia neipaninga paura hikoEngari i ngā wāhi e tata ana ki te moana, ki ngā awa rānei, he tote te hau, ā, ka waikura pea ngā pou, he pai ake te whakamahi i ngā paparanga tiaki e rua –whakapūmau wera-tōmepaninga paura– kia kore ai e waikura. I ngā tāone nui o uta, he nui te whakamahi i te paparanga kotahi o te whakakikorua wera. Ko te mea nui, ko ngā pou rama huarahi e tū ana i waho i ngā wā katoa, e uaina ana, e takoto ana i te rā, ka tīmata te waikura mēnā kāore i te tiakina pai, ā, ka waiho pea tēnā hei raruraru haumaru. Nō reira, he mea nui kia whakamahia ngā rauemi me ngā tikanga tiaki tika kia roa ai te ora o ngā pou, kia noho haumaru hoki.

Kāore e taea te wareware i ngā āhuatanga o te kawenga taiao. He whakaritenga motuhake ā-rohe mōātete hauKo ngā mania e tutuki ana i te paerewa ātete hau o27 m/h, engari ko ngā wāhi e pāngia ana e te awhiowhio e hiahiatia ana he paerewa o36 m/steitei ake rānei. Mēnā he maha ngā taputapu e tāutahia ana, me tatau te taumaha katoa o ngā rama huarahi, ngā kāmera, me ngā whare hei ārai i te taumaha rawa. Me ōrite hoki te turanga ki ngā pou; me nui ake ngā pūtu punga me ngā turanga raima mō ngā pou cantilever teitei.

Mō te whakatū i ngā rama huarahi, he maha ngā mea hei whakaaroaro. Ehara i te mea ko ngā ture anake, engari ko te āhua hoki. Hei tauira, i ngā tāone iti, ka taea noa te whakairi ki ngā pakitara. Engari i ngā tāone nui, me ōrite ngā pou rama huarahi ki te momo me te tae o te tāone. Ka whai te tukanga katoa i ngā aratohu tino pakari kia pai ai te haumaru me te mahi pai. Kāore rātou e whakamahi i ngā pou he angiangi rawa, kāore rānei e tutuki i ngā paerewa.
