He Whakamārama Taipitopito mō te Pūnaha Arataki Ararewa
Ko te mahi matua o te pūnaha ararewa he whakarite kia maeneene te oma o te waka ararewa me te taumaha whakataurite i te ara reti kua pumau - te reri ārahi i te ara hiki.
Ko te pūnaha arataki he mea hanga mai i ngā wāhanga matua pērā i ngā reera arataki, ngā hū arataki me ngā whāriki reera arataki.
●Ngā reera ārahi: Ko ngā reera ārahi ngā taputapu ārahi mō te whakahaere i te waka ararewa me te taumaha taurite, kia tika ai te neke o te ararewa. Ko ngā reera ārahi he mea hanga ki ngā reera rino me ngā pereti hono, e tāutahia ana ki te ara hiki hei whakarite i te tūranga me te ahunga nekehanga o te ararewa i roto i te ara hiki. (Ka arotahi ngā ihirangi e whai ake nei ki tēnei)
●Hu arataki: Ka tāutahia ngā hu arataki ki runga i te motuka me te anga taumaha taurite, ā, ka mahi tahi me ngā reera arataki kia tino piri te nekehanga o te ararewa ki te arataki o ngā reera arataki. E rua ngā momo hu arataki: he reti me he roera, he rerekē ngā painga o ia momo.
●Ngā whāriki arataki: Ka whakapirihia ēnei whāriki ki te pakitara, ki te kurupae rānei o te ara hiki hei tautoko me te whakau i ngā arataki, kia mau ai te pumau o ngā arataki me te haumaru o te mahi a te ararewa.
Te mahi a te pūnaha aratohu
Ko te mahi matua o te pūnaha ārahi he whakawhāiti i te herekore o te nekehanga o te motuka me te taumaha taurite kia taea ai e rātou te neke ake, te heke iho i runga i ngā reri ārahi anake. Mā te mahi tahi a ēnei wāhanga, ka whakarite te pūnaha ārahi i te mahi tika me te haumaru o te ararewa i roto i te pou.
Ngā ara ārahi
● Ngā āhuatanga o te ara ārahi
(1) Ko ngā ara ārahi me ngā hu ārahi ngā wāhanga ārahi o te waka ararewa me te taumaha taurite.
(2) Ngā momo arataki arataki: Momo-T, Momo-L (tere iti), he awaawa, me ētahi atu.
Ko ngā mata mahi o ngā momo ara ārahi e toru whakamutunga kāore i te tukatukahia. He mea whakamahi noa ēnei mō ētahi ararewa he iti te ahunga whakamua, ā, he iti hoki ngā whakaritenga mō te pumau o te oma, pērā i ngā arawhata whaipainga me ngā arawhata hangarau hanga. A. Ko te ara ārahi momo tuatahi (momo-T) e whakamahia ana i roto i te nuinga o ngā ararewa. Ko ngā ara ārahi ararewa e kōrerohia ana e tātou e pā ana ki tēnei momo ara ārahi. He pai te ātete piko, ā, he pai te ngāwari ki te miihini.
B. Ko ngā tawhā matua o ngā ara ārahi momo-T ko: te whānui o raro b, te teitei h me te matotoru o te mata mahi kb*k*h. Ko ngā ara ārahi e whakamahia whānuitia ana ko te T75, T89, T127, me te T140.
(3) Ko te roa o te ara ārahi he 3~5m te nuinga. Kāore e whakaaetia te hononga tika mā te whakarewa me ngā pūtu. Me whakamahi pereti hononga motuhake.
(4) He whakaritenga anō mō te rauemi, te taratara o te mata, me te tika o te tāutanga o te ara ārahi.
●Ngā whakaritenga tāutanga mō ngā whāriki arataki
Me iti iho i te 1000mm te tawhiti o te whāriki arataki tuatahi mai i te papa o raro o te poka, ā, me iti iho i te 500mm te tawhiti o te whāriki arataki teitei rawa mai i te papa o runga o te kakau.
Me tino whai whakaaro te tahora tūranga o te whāriki arataki kia kore ai e pokanoa te tūranga o te pereti hono arataki tetahi ki tetahi, no reira me huihuia i mua, me tatau tika rānei.
Me whai kia rua ngā whāriki whāriki whāriki ia rēra ārahi, kia
