Te roa me te rahi o te maitai

I. Te roa me te rahi o te maitai

Ko te roa o te maitai te rahi taketake o ngā momo maitai katoa, e pā ana ki te roa, te whānui, te teitei, te whānui, te pūtoro, te whānui o roto, te whānui o waho me te matotoru o te pakitara me ētahi atu. Ko ngā waeine ture mō te ine i te roa o te maitai ko te mita (m), te henimita (cm), te mirimita (mm). E whakamahia ana hoki te inihi i roto i te whakamahinga o nāianei, engari ehara i te waeine ture mō te ine.

Ngā rahinga o te awhe o te maitai
He huarahi whai hua te whakatakoto i te rahi o te awhe o te maitai hei penapena rauemi. Ko te rūri awhe he mea e kore e iti iho te roa, te roa-mā-te-whānui rānei i tētahi rahi kua whakaritea, he mea rānei e tukuna ana te roa, te roa-mā-te-whānui rānei i roto i tētahi whānuitanga o ngā inenga. Ka taea e te wāhanga whakaputa te whakaputa me te tuku i runga i ngā whakaritenga rahi.

Roa mutunga kore (roa noa)
Mēnā he rahi hua (roa, whānui rānei), i roto i te paerewa kua whakatakotoria i roto i te whānuitanga, ā, kāore e hiahiatia he rahi pumau e kiia ana he waewae mutunga kore. Ko te roa mutunga kore e kiia ana ko te roa noa. Ka whakaaetia ngā rauemi whakarewa e tukuna ana i roto i te ine mutunga kore mena ka tukuna i roto i te roa kua tohua. Hei tauira, mō te maitai porowhita noa kāore i te neke atu i te 25mm, ko te roa e whakaritea ana ko te 4 ~ 10m, ka taea te tuku maitai porowhita katoa i roto i tēnei awhe.

3. Te roa

Ko te tapahi ki tētahi rahi kua whakaritea e ai ki te ota ka kiia he rahi. Ina tukuna he roa kua whakaritea, me rite te roa o te rauemi whakarewa ki tā te kaihoko i roto i te kirimana ota. Hei tauira, ki te kī te kirimana ka tukuna ngā taonga i tētahi roa kua whakaritea o te 5m, me 5m te roa o ngā rauemi kua tukuna. Ka whakakorehia ngā rauemi poto ake, roa ake rānei i te 5m. Engari ko te mea pono, kāore e taea te tuku i te 5m katoa, nō reira kua whakaritea kia whakaaetia te peka pai hei utu mō te peka kino.

4 ngā wā o ngā waewae

E ai ki te rahi pumau o te ota e hiahiatia ana hei tapahi i te maha katoa ka kiia he maha. Me rite te roa o te konganuku ki te maha whakauru o te roa kua tohua e te Kaihoko i roto i te kirimana ota (e kiia ana ko te waewae kotahi) (me te whakatuwheratanga kani). Hei tauira, me kī te kaihoko i roto i te kirimana ota kia 2m te roa o te waewae kotahi, nō reira ko te roa he 4m ina tapahia kia rua ngā waewae, 6m ina tapahia kia toru ngā waewae, ā, ka tāpirihia kia kotahi, kia rua rānei ngā waha kani.

Kua tohua te nui o te kani i roto i te paerewa. Ina tukuna te rahi, ko te rerekētanga pai anake ka whakaaetia, ā, kāore he rerekētanga kino e whakaaetia.

5. Waewae poto

Ko te rūri poto he iti iho i te rohe o raro o te roa mutunga kore kua tohua i roto i te paerewa, engari kaua e iti iho i te roa iti rawa e whakaaetia ana, ka kiia he rūri poto. Hei tauira, ko te paerewa paipa wai me te hau e whakarite ana kia 10% (mā te maha o ngā wahi) he 2-4m te roa o ngā paipa rino poto e whakaaetia ana i roto i ia puranga. Ko te 4m te rohe o raro o te roa mutunga kore, ā, ko te roa iti rawa e whakaaetia ana ko te 2m.

6. Waewae whaiti

Ko te rūri whaiti he mea he iti iho te whānui i te rohe o raro o te whānui mutunga kore kua tohua i roto i te paerewa, engari kaua e iti iho i te whānui whaiti rawa e whakaaetia ana. Me aro nui ki te tauine me te tauine whaiti rawa kua tohua i roto i ngā paerewa e tika ana ina tuku taonga i runga i ngā tauine whaiti.
