Kiriuhi ā-wai mō te tuanui piri-ā-koe

1. Te horoi i te mata o raro:
Me horoi ngā paru, ngā paru hinu, te onepu i runga i te mata o te paparanga turanga, ngā kōhatu me ngā puku moata e pupū ake ana i te mata. Me mahi te mahi horoi i ngā wā katoa i te wā o te hanganga, ā, me whakatika te mata maeneene. Tangohia rawatia te moata sima me ētahi atu mea e piri ana ki te putanga waikeri, te auahi me te pakitara paipa;
Ka whakamahia te moata sima mō ngā kokonga tāne me ngā kokonga wahine hei hanga i tētahi koki pewa porowhita, ko te radius iti rawa o te kokonga wahine he 50mm, ā, ko te radius iti rawa o te kokonga tāne he 20mm. Mēnā he wai mārama kei runga i te mata o te turanga, ka taea te hanga mā te tahia atu.

2. Whirihorahia te whakapiri sima:
E ai ki te sima: wai = 2:1 (ōwehenga taumaha). Tuatahi ringihia te wai ki roto i te peere whakaranu kua rite kia rite ki te ōwehenga, kātahi ka tāpirihia te sima ki roto i te wai, rumakina mō te 15-20 meneti ka rumakina katoatia, ringihia te wai taikaha ki runga i te mata o te peere; kātahi ka tāpirihia te 5% ki te nui o te sima. 8% te kāpia hanga polymer (kaihoko pupuri wai), whakaohokia ki te mīhini whakaranu hiko, ā, ko te wā whakaoho he neke atu i te 5 meneti.

3. Te whakamātautau i te whakatakotoranga o te turanga rapa:
E ai ki ngā āhuatanga o te papa hanga, whakahaerehia he tūnga tika, whakatauhia te ahunga o te whakatakotoranga rauemi kopiko, pikohia te rārangi whakahaere rauemi kopiko ki runga i te paparanga turanga, ka whai i te ahunga rere hei whakahaere i te whakamātautau whakatakotoranga rauemi kopiko mai i te iti ki te teitei.

4. Haehaea te pepa tuku i te raro o te koiri:
Kia oti te whakamātautau i te rauemi kua takai, tapahia te rauemi kua takai hei whakatakoto, ka whakatakotoria ki runga i te mata o raro (arā, me te pepa tuku o raro e anga ake ana), ka tihorea te pepa tuku rauemi kua takai. I te tihorenga, me pupuri te pepa tuku kua tihorea i te koki koi o te 45 ki te 60 nekehanga ki te mata piri kia kore ai e unuhia te pepa tuku, ā, me ngana kia noho marino noa, engari kia kore he kita.

5. Te whariki koiri:
Tikanga hurihuri: whakarārangihia te rauemi hurihuri ki te rārangi tohutoro, kātahi ka ngana ki te whakatakoto. Whakamahia he maripi pepa hei tapahi mārire i te pepa tuku kia 5m te roa. Kia tūpato kei rakuraku te rauemi hurihuri. Haehaea mārire te pepa hurihuri kāore anō kia hurihia mai i muri. Whakatuwheratia, ā, i te wā kotahi, pana mārire te koiri kāore anō kia hurihia ki mua i te rārangi tohutoro. Whakatakotoria me te haehae i te pepa wehewehe. Kia oti te papa whakatārewatanga, ka hurihia ngā koiri 5m te roa e toe ana o te papa whakamātautau o mua, ka whakapirihia ki te paparanga turanga e ai ki te tikanga i runga ake nei.
Tikanga hiki: Whakatakotoria te rauemi porotaka kua tapahia ki runga i te mata o raro (arā, ko te pepa tuku o raro e anga whakarunga ana), i muri i te tihorenga i te pepa tuku katoa o te rauemi porotaka, kātahi ka waruhia te whakapiri sima ki runga i te mata here o te rauemi porotaka me te mata o raro hei whakatakotoranga, kātahi ka hikihia e te tokorua mai i ngā pito e rua o te koiri, ka hurihia ka whakatakotoria ki te tūranga hei whakatakotoranga. Ka taupatupatuhia te rauemi koiri me te rauemi koiri e tata ana. Ina taupatupatuhia ngā taha roa me ngā taha poto, ka tangohia te kiriata wehewehe taupatupatu rauemi koiri o runga me raro.

6. Putanga hau hurihuri:
I muri i te whakatakotoranga o te rauemi rōra, whakamahia he pereti rapa ngohengohe, he roera rānei hei waru me te tuku i te hau mai i waenganui ki tērā taha o te rauemi rōra kia piri katoa te rauemi rōra ki te mata o raro. Ina pania, ka whakapirihia te koiri e whai ake nei, hiki ake te pepa tuku i te hope o te koiri o raro, whakaritea te koiri o runga ki te rārangi whakahaere koiri, ka whakapiri ki te koiri o raro, waruhia, ka tukuna te hau kia tino kī tonu i te piri.

7. Te hiri o te taha o te kopa me te hiri o te pane:
Hanganga rauemi piri taha-kotahi mō te taha o te tuanui: ka taupatupatu ngā taha poto o ngā koiri tata, ā, ka whakamahia te rīpene hipoki HNP hei whakamahana me te here (ko te whānui o te rīpene hipoki tuanui he 100 mm, ā, ko te whānui o te rīpene hipoki o te papa o raro he 160 mm). Ka whakamahanahia te taha roa, ka piri-ā-ringa, ā, kaua e iti iho i te 80mm te whānui o te taha. Kia oti te papa whānui te whakatakoto, me mahi te hanga taha o te tuanui i muri i ngā haora 24. Horoia te paru me te puehu i te taha o te tuanui i te wā e hangaia ana, kātahi ka tangohia ngā koiri o runga me raro o te kiriata wehe hononga o te tuanui (kāore e hiahiatia kia haehae te kiriata wehe e te taha poto), ā, whakamahia he pū wera hei here i te wā e whakamahana ana.
Hanganga o te rauemi piripiri takirua-taha: haehaea tika te kiriata wehe i te hononga o te taha o runga me raro o ngā rauemi piripiri, ka waru i te taha e taupokina ana (whakapirihia i te wā kotahi ina pania he wāhi nui o te whakapiri sima) whakapirihia te whakapiri sima ki te whakapiri, hiritia tika ki te whakapiri sima, ko te whānui o te taha o te taha roa me te taha poto: kaua e iti iho i te 80mm. Hei whakamutunga, whakamahia te whakapiri sima hei whakawhāiti me te hiri.

8. Te tiaki me te tiaki i ngā hua kua oti:
Waiho mō ngā hāora 24 ki te 48 (ko te wā motuhake ka whakawhirinaki ki te pāmahana o te taiao, i raro i ngā āhuatanga noa, ko te teitei ake o te pāmahana, ko te poto ake o te wā e hiahiatia ana). I ngā rangi pāmahana teitei, me ārai te paparanga ātete wai i te pānga o te rā, ā, ka taea te hipoki ki te kakahu whakamarumaru, ki ētahi atu mea rānei.
