Raina Hanga Kiriata Maka Manawa
E whakamahia whānuitia ana ngā kiriata manawa i roto i ngā ahumahi hauora, hauora, hanga whare, me ngā ahumahi motuka, me ētahi atu. E whakamahia ana ngā hua kiriata hei hanga nāpi pēpi, ngā raina tarau poto, ngā tarau kore e taea te pupuri i te mimi mō ngā pakeke, ngā kākahu tiaki hauora, ngā kākahu tiaki ahumahi, te tākai hua hou, ngā rauemi tiaki tuanui, me ngā rauemi ārai wai manawa.
Ngā āhuatanga hangarau matua
1. Utaina hau aunoa me te mahi whakamaroke me te inenga taumaha maha-wāhanga.
2. I ōrite te wāhanga whakaputa ki te matotoru me te āhuatanga rheological o te rauemi mata.
3. Ko te pūnaha oma whakaputa-tahi maha-paparanga me te pane mate aunoa.
4. Pūnaha ine matotoru aunoa katoa kua whakauruhia ki te pūnaha whakahaere raina whakaputa.
5. Teihana whakarewa ātete-wiri mahi-teitei, he mea whakapūmau ki te taha hiko me te pouaka korehau rūma-rua.
6. Wāhanga totoro mahi-teitei: mā te hangarau totoro āputa iti ka iti ake te rahi o te kume, ā, ka whakaitihia te herenga kiriata.
7. Mā te wāhanga whakairo tuarua ka tino ngawari te ahua, ā, ka whakaiti i te kanapa koretake.
8. Mā te kuti me te tukatuka i ngā taha whakarārangi ka taea te whakamahi katoa i ngā rauemi mata.
9. Ka tautoko te mīhini hurihuri tereina tere-rahi i te tapahi ipurangi, ā, e wātea ana mō ngā diameter me ngā whānui rerekē o te rīra. Ko ngā painga ko:
(1) Te whakahaere tika i te kumekume porowhita kati
(2) Pūnaha whakahaere arotautanga o te takai kiriata
(3) Kāore he piripiri, he rīpene rānei i te wā e whakawhiti ana i te rīra, kāore he para
