He wāhanga nui te rama tohu huarahi o te hangarau huarahi, e whakarato ana i te tautoko taputapu kaha mō te haere haumaru o ngā waka rori. Heoi, me mahi tonu te mahi tohu huarahi i te wā o te tāutanga, ā, me whai whakaaro katoa ki te kaha miihini, te pakari me te pumau i te wā e whiwhi ana i te kawenga i roto i te whakamahere hanganga. Muri iho, ka whakamāramahia e au te tikanga tāuta tika i ngā pou rama tohu huarahi me ngā tikanga whakapaipai rama tohu e whakamahia whānuitia ana kia mārama ai koe.
Te tikanga tāuta tika i te pou rama tohu huarahi
E rua ngā tikanga tatau noa mō ngā pou rama tohu: ko te tuatahi he whakangawari i te hanganga rama tohu hei pūnaha pou mā te whakamahi i ngā mātāpono o te miihini hanganga me te miihini rauemi, me te whiriwhiri i te tikanga whakamahere āhua rohe hei tirotiro i te tatau.
Ko tētahi atu ko te whakamahi i te tikanga kaute tata o te tikanga huānga mutunga kore hei tirotiro. Ahakoa he tika ake te tikanga huānga mutunga kore mā te whakamahi i te mīhini kaute, i whakamahia whānuitia i taua wā nā te mea ka taea e te tikanga āhua rohe te homai whakatau tika, ā, he māmā noa iho te tikanga kaute, he ngāwari hoki ki te mārama.
Ko te hanganga o runga o te pou tohu he hanganga rino te nuinga, ā, ko te tikanga whakamahere āhua rohe ka tīpakohia i runga i te ariā tūponotanga. Ko te whakamahere ka hāngai ki te āhua rohe o te kaha amo me te whakamahinga noa. Ko te turanga o raro he turanga raima, ā, ko te whakamahere ariā o te hangarau turanga ka tīpakohia.
Ko ngā taputapu pou tohu huarahi e whakamahia whānuitia ana i roto i te hangarau huarahi koia ēnei:
1. Momo pou
He maha ngā wā ka whakamahia ngā pou rama tohu momo pou hei tāuta i ngā rama tohu āwhina me ngā rama tohu mō te hunga hīkoi. He maha ngā wā ka tāutahia ngā rama tohu āwhina ki te taha maui me te taha matau o te ara waka.
2. Momo Cantilever
He pou rama poutū me te ringa whakawhiti te pou rama tohu whakarara. Ko te painga o tēnei taputapu ko te whakamahi i te taputapu me te whakahaere i ngā taputapu tohu i ngā whakawhitinga maha-wāhanga, e whakaiti ana i te uaua o te whakatakoto hiko hangarau. Ina koa, he māmā ake te whakamahere i ngā kaupapa whakahaere tohu maha i ngā whakawhitinga waka uaua.
3. Momo cantilever takirua
Ko te pou rama whakawhiti takirua he mea tito mai i tētahi pou poutū me ngā ringa whakawhiti e rua. He maha ngā wā e whakamahia ana mō ngā ara matua me ngā ara āwhina, ngā rori matua me ngā rori āwhina, ngā whakawhiti āhua-T rānei. Ka taea te whakatakoto whakapae i ngā ringa whakawhiti e rua, ā, ka taea te whakamahi mō ngā kaupapa maha.
4. Momo Gantry
He maha ngā wā ka whakamahia te pou rama momo gantry i ngā wāhi e whānui ana te whakawhitinga huarahi, ā, me tāuta ngā whakaurunga rama maha i te wā kotahi. He maha ngā wā ka whakamahia i te tomokanga o te kauhanga me te tomokanga o te tāone.
