Te whakamahinga o ngā puranga rino āhua-U kua hurihia wera mō ngā whare nunui

He hua hangarau hou ngā puranga rau āhua-U i whakaurua mai i Netherlands, i te Tonga-mā-rāwhiti o Āhia me ētahi atu wāhi. Ināianei kua whānuitia te whakamahinga puta noa i te Pearl River Delta me te Yangtze River Delta. Ngā wāhi tono: awa nui, tāwharau moana, whakahaere awa pokapū, hanga poka turanga, huarahi nui, piriti, kaupapa ā-tāone me te hanga anō i te tauranga taumata tuatoru.
He kupu whakataki ki ngā painga o te whakamahinga o ngā puranga rau āhua-U:
1. Wāhanga pupuri nui. Ko te roa o te wāhanga pupuri puranga kotahi o te puranga raima kua whakapūmauhia he āhua-U e tae ana ki te 1 mita, he tino rerekē tēnei i ngā puranga rau tuku iho me ngā momo puranga kua whakapūmauhia noa.
2. He tino pai te āhua o te hanganga ahotea whakawhiti-wāhanga. Kua whakamahia te hoahoa whakawhiti-wāhanga hanganga āhua-U hei whakanui ake i te teitei whakawhiti-wāhanga me te nekehanga ātete whakawhiti-wāhanga, kia pai ake ai te mahi ahotea o te hanganga.
3. He mārama ngā painga ōhanga. Ka whakamahia te hanganga āhua-U, ka tino whakaiti i te nui o te raima e whakamahia ana i roto i tēnei momo puranga ki te whakataurite ki ngā puranga rau noa i te teitei whakawhiti-wāhanga kotahi. I taua wā anō, ka whakamahia e te puranga rau āhua-U te hoahoa hanganga kua whakamātauhia, ka tino whakaiti i te ahotea me ngā whakaritenga whakapakari i runga i te kaupapa o te whakatutuki i ngā whakaritenga whakapakari ahotea hanganga. Ka piki ake te nui o te whakapakari i roto i te hanganga, ka whakaitihia hoki te utu. I taua wā anō, ka eke te whānui pupuri oneone o tēnei momo puranga kotahi ki te 1 mita, he tino tawhiti rawa atu i te momo puranga noa. I runga i ngā āhuatanga o runga ake nei, ko te utu o ngā puranga rau raima kua whakamātauhia āhua-U he tata ki te 30% te iti iho i te utu o ngā puranga rau noa tuku iho, he pai ngā painga ōhanga.
4. Momo tauira. Ka taea te whiriwhiri ngāwari i ngā momo puranga raima kua whakapūmauhia te āhua-U kia tutuki ai ngā hiahia o te kaupapa mā te whakamahi i ngā teitei wāhanga rerekē, ngā āhua whakakaha, ngā rahinga whakakaha me te roa o ngā puranga kia rite ki ngā whakaritenga mahi ā-pūkaha o te momo puranga. Whakatutuki i te arotautanga o te hanganga whakawhiti-wāhanga me te whakanui ake i ngā painga ōhanga.
5. He poto te wā hanga. Ka whakamahia e ngā puranga raima kua oti te hanga i mua i te wheketere te aratau hanga-a-mua o ngā puranga raima āhua-U, ā, ka whakamahia te mīhini ki te papa hanga hei hanga i te pakitara puranga, ka whakapotohia te wā hanga ki te whakataurite ki ngā tikanga tuku iho.
6. Hangarau hanga, whānuitanga o te whenua e tika ana, me te wāhanga whakawhiti ataahua i muri i te hanganga puranga
