ngā pou haumaru maitai

Me tutuki te hohonutanga o te anga i ngā whakaritenga hoahoa, ā, me tutuki hoki te hohonutanga o te anga i ngā whakaritenga e whai ake nei:
1. Ina tanumia te anga ki te whenua maroke, ki te wai pāpaku rānei, mō te paparanga raro ātete-ā-roto, me 1.0-1.5 ngā wā o te whānui o waho o te anga te hohonu o te tanumanga, engari kaua e iti iho i te 1.0m; mō te paparanga raro ātete-ā-roto pērā i te onepu me te paru, me rite te hohonu o te tanumanga ki tā runga ake nei, engari he mea tika kia whakakapia ki te oneone ātete-ā-roto kia kaua e iti iho i te 0.5m i raro i te taha o te ngongo tiaki, ā, me neke ake te whānui whakakapinga i te whānui o te ngongo tiaki mā te 0.5-1.0m.
2. I roto i te oneone ngohengohe o te wai hohonu me te awaawa, me te paparanga paru matotoru, me tomo te taha raro o te ngongo tiaki ki roto i te paparanga ā-roto; ki te kore he paparanga ā-roto, me tomo ki roto i te paparanga kirikiri me te kirikiri nui i te hohonu o te 0.5-1.0m.
3. Mō ngā awaawa e pāngia ana e te horoinga, me tomo te taha raro o te ngongo tiaki ki raro i te rārangi horoi whānui, kaua e iti iho i te 1.0m. Mō ngā awaawa e tino pāngia ana e te horoinga ā-rohe, me tomo te taha raro o te ngongo tiaki ki raro i te rārangi horoi ā-rohe.
4. I ngā wāhi oneone tio ā-wā, me uru te taha raro o te ngongo tiaki ki roto i te paparanga oneone kāore anō kia tio i raro i te rārangi tio, kaua e iti iho i te 0.5 m; i ngā wāhi hukapapa tonu, me uru te taha raro o te ngongo tiaki ki roto i te paparanga hukapapa tonu, kaua e iti iho i te 0.5 m. 0.5 m.
5. I te whenua maroke, i te wā rānei he iti iho i te 3m te hohonutanga o te wai, ā, kāore he paparanga oneone ngoikore i te raro o te moutere, ka taea te tanu i te anga mā te tikanga tapahi tuwhera, ā, me whakakīkī te oneone uku kua whakakīia ki raro me te taha o te anga kia maha ngā paparanga.
6. Ina iti iho i te 3m te hohonu o te tinana rango, ā, kāore i te matotoru te paru me te oneone ngohengohe i raro i te moutere, ka taea te whakamahi i te tikanga tanu tuwhera; ina totohu te hama, me tino aro turuki te tūnga papatahi, te piko poutū me te kounga hononga o te anga.
7. I ngā wai e nui ake ana te hohonutanga o te wai i te 3m, me āwhina te papa mahi me te anga ārahi i te anga tiaki, ā, me whakamahi ngā tikanga wiri, te patu, te pupuhi wai, me ētahi atu hei totohu.
8. Me 2m te teitei ake o te mata o runga o te anga i te taumata wai o te hanganga, i te taumata wai whenua rānei, me te 0.5m te teitei ake i te papa o te hanganga, ā, me tutuki tonu tōna teitei i ngā whakaritenga mō te teitei o te mata paru i roto i te kōhao.
9. Mō te ngongo tiaki kua whakatakotoria ki tōna wāhi, ko te rerekētanga e whakaaetia ana o te mata o runga ko te 50mm, ā, ko te rerekētanga e whakaaetia ana o te piko ko te 1%.
