Ngā Painga o ngā Paipa Hanganga Whakarewa Matao kua Whakarewahia
I roto i ngā rāngai hanga me te hanga, he mea nui te whiriwhiri i ngā rauemi me ngā tikanga whakarewa hei whakaoti angitu i tētahi kaupapa. Ko tētahi o ngā rauemi kua rongonui i ngā tau tata nei ko te paipa hanganga whakarewa matao. He maha ngā painga o tēnei hua auaha i ngā paipa tuitui tuku iho, inā koa ngā paipa tuitui porowhita.
Mātao hanganga whakarewa i hangaiaKa hangaia te paipa mā te tukanga hanga-makariri, arā, ko te piko me te hanga i ngā koiri maitai ki te āhua e hiahiatia ana. Ko te hua he paipa kaha, he pakari hoki, engari he mama, he ngāwari hoki ki te whakamahi. Hei tāpiri, mā te tukanga hanga-makariri ka mau tonu te hanganga me te tika o ngā āhuatanga o te paipa, ā, he mea tino pai mō ngā mahi whakarewa.

Whakamātautau Waipūmau
Me whakamātautau ia roa o te paipa e te kaihanga ki te pēhanga wai-pūmau ka puta he ahotea i roto i te pakitara o te paipa kāore i raro iho i te 60% o te kaha tuku iti rawa kua tohua i te pāmahana rūma. Me whakatau te pēhanga mā te whārite e whai ake nei:
P=2St/D
Ngā Rerekētanga e Whakaaetia ana i roto i ngā Taumaha me ngā Ahu
Me paunatia motuhake ia roa o te paipa, kaua hoki tōna taumaha e neke atu i te 10% neke atu i tōna taumaha matapae, 5.5% rānei i raro iho i tōna taumaha matapae, e tatauhia ana mā te whakamahi i tōna roa me tōna taumaha mō ia wae roa.
Kaua te whānui o waho e neke atu i te ±1% mai i te whānui o waho kua tohua.
Kaua te matotoru o te pakitara i tētahi wāhi e neke ake i te 12.5% i raro i te matotoru pakitara kua tohua.
Roa
Roa matapōkere takitahi: 16 ki te 25 putu (4.88 ki te 7.62m)
Roa matapōkere takirua: neke atu i te 25 putu ki te 35 putu (7.62 ki te 10.67m)
Ngā roa ōrite: te rerekētanga e whakaaetia ana ±1inihi
Ngā mutunga
Me whakapaipai ngā puranga paipa ki ngā pito papatahi, ā, me tango ngā kōhao i ngā pito.
Ina tohua te pito paipa hei pito piko, me 30 ki te 35 nekehanga te koki
Ko tētahi o ngā painga matua o te hanganga whakarewa matao-hangapaipa mō te whakarewako tōna kaha ki te tu atu i ngā pāmahana me ngā pēhanga teitei. He rerekē ki ngā paipa tuku iho, he ngawari ki te waikura me ētahi atu momo pirau, he mea hanga ngā paipa matao kia tu atu i ngā uauatanga o te whakarewa me ētahi atu tukanga ahumahi. Nā tēnei ka pai ai mō te whakamahi i roto i ngā momo tono mai i te hanganga whare ki ngā kaupapa hanganga.
Ko tētahi atu painga o ngā paipa hanganga whakarewa matao ko tōna utu iti. Ka taea e te tukanga whakarewa matao te whakaputa paipa i roto i ngā momo rahi me ngā āhua, ka whakaiti i te hiahia mō ngā tukanga whakarewa me te miihini utu nui. Mā tēnei ka iti ake te utu me te pono o te hua pērā i te paipa kore hononga, te paipa whakarewa rānei. Hei tāpiri, nā te mama o te paipa whakarewa matao ka māmā ake te kawe me te tāuta me te whai hua ake, ka nui ake te ataahua.
He tino whai hua ngā ngongo tuitui porowhita mai i te tukanga hanga matao. Nā te kaha me te ngāwari o ngā ngongo hanga matao, he mea pai mō te hanga hononga porowhita pakari, ā, kāore e turuturu. Nā tēnei he mea pai mō ngā mahi pēnei i ngā pūnaha waikeri raro whenua, ngā raina wai, tae atu ki ngā pūnaha whakamakuku ahuwhenua. Hei tāpiri, mā te mata maeneene o ngā paipa hanga matao ka whakaiti i te tūponotanga o te waku me te pakaru, ka roa ake te ora o ngā paipa, ka whakaiti hoki i te hiahia mō te tiaki me te whakatikatika.
I te nuinga o te wā, he maha ngā painga o ngā paipa hanganga whakarewa matao, ā, he pai rawa atu tēnei mō ngā mahi whakarewa, inā koa ngā paipa tuitui porowhita. Nā te kaha, te roa, me te iti o te utu, he mea ātaahua tēnei mō te whānuitanga o ngā ahumahi, mai i te hanga ki te hanga. I te mea kei te piki haere tonu te hiahia mō ngā rauemi kounga teitei, pono hoki, ka piki haere te rongonui o ngā paipa hanganga whakarewa matao mō ngā mahi whakarewa.
