Ngā painga o te paipa whakarewa pewa porowhita i raro i te wai:

1. Hanganga whai hua:

He hoahoa whakarewa porowhita ngā paipa SSAW e āhei ai te whakaputa pai me te whakaiti i te wā hanga. Nā tēnei āhuatanga ahurei koinei te whiringa tuatahi mō ngā kaupapa hanga nui pēnei i te hinu me tengā paipa hau, ngā pūnaha tuku wai, me ngā papa keri ki tai. Mā te tukanga whakarewa tonu ka whakarite kia teitei te kounga o te hanganga, ka roa ake te mau me te roa o te ora o te paipa.

2. Kaha me te ngāwari tino pai:

Mā te hanganga porowhita o te paipa SSAW ka kaha ake, ka taea ai te ātete i ngā pēhanga o waho me roto. Ka taea e ēnei paipa te ātete i ngā āhuatanga tino kino o te hau, ā, he pai mō ngā mahi o runga me raro i te whenua. Hei tāpiri, mā te ngāwari o ngā paipa SSAW ka taea te urutau me te tāuta ki ngā momo whenua rerekē, tae atu ki ngā whenua taratara me ngā oneone koretake.

3. Otinga utu-whai hua:

Ka piki ake te hua o ngā mahi whakarewa tonu, ā, ka whakaitihia hoki ngā hapa me ngā utu whakarewa. Hei tāpiri, ka tukuna e ngā paipa whakarewa porowhita-uru-pōro te kaha me te roa, ka whakaitihia ngā utu tiaki me te whakatika i roto i tō rātou oranga, ka waiho hei whiringa ōhanga mō te ahumahi.

Ngā wero e pā ana ki ngā paipa whakarewa pewa porowhita i raro i te wai:

1. Te whakahaere kounga:

Nā te uaua o ngā tukanga whakarewa e pā ana ki te hanga i ngā paipa whakarewa āwhata porowhita, he uaua te whakarite i te kounga pumau. Mēnā kāore e whakahaeretia tika ngā tawhā whakarewa, ka puta ngā hapa whakarewa pērā i te tapahi raro, ngā pūwero, me te korenga o te hanumi. Hei whakakore i tēnei wero, he mea nui ngā mahi whakahaere kounga tino pakari me ngā pūnaha aroturuki matatau i te wā o te tukanga hanga.

2. Te whānuitanga here o te diameter o te paipa:

Ahakoa he pai ngā paipa whakarewa porowhita i raro i te pewa mō ngā mahi whānui, kāore pea e pai mō ngā ahumahi e hiahia ana ki ngā rahi paipa iti ake. He pai ake te tukanga hanga mō ngā paipa whānui ake, ā, he iti noa iho te wātea mō ngā kaupapa iti ake pēnei i ngā paipa kāinga me ngā whakamahinga ahumahi iti. Mō ēnei whakaritenga, me whai whakaaro ki ngā hangarau hanga paipa rerekē.

3. Paninga mata:

Ko tētahi atu wero e pā ana ki te umanga paipa SSAW ko te whakarite kia tika, kia pakari hoki ngā paninga mata hei tiaki i te waikura me te kakahu. Ko te paninga ki ngā mata porowhita me whai taputapu matatau me te tohungatanga kia ōrite te kapi me te piri. He mea nui te paninga mata tika hei whakaroa i te roa o te mahi a ngā paipa whakarewa porowhita kua rukuhia ki raro, inā koa i roto i ngā taiao uaua.

Hei whakamutunga:

Kua whakamātauhia te whai huatanga o ngā paipa whakarewa porowhita i roto i te ahumahi hou, e tuku ana i te whai huatanga, te kaha me te whai huatanga o te utu. Nā tōna hononga whakarewa porowhita ahurei ka taea te whakaputa pai me te whakanui ake i te roa, ka pai mō ngā kaupapa hanga nui. Heoi, kia angitu tonu ai, kia whānuitia ai te whakamahinga o tēnei hangarau hanga, me aro atu ki ngā wero pēnei i te whakahaere kounga, te whānuitanga iti o te diameter, me ngā paninga mata. Mā te wikitoria i ēnei wero mā te whanaketanga hangarau me te mahi tahi a te ahumahi, he pai te heke mai o ngā paipa whakarewa porowhita i roto i te whakawhiti me te pupuri i ngā hanganga nui huri noa i te ao.
