A takirere kuahahe takirere e neke ana ki runga, ki raro i te rārangi tika i te nohoanga takirere (te mata hiri), ko te wāhanga whakatuwhera me te wāhanga kati (te kūaha) e whakakahangia ana e te kakau takirere.

1. He aha tetakirere kuahae mahi ana

He momo takirere kati e kiia nei ko te takirere kēti e whakamahia ana hei hono, hei momotu rānei i te reo i roto i te paipa. He maha ngā whakamahinga o te takirere kēti. Ko ngā takirere kēti e whakamahia whānuitia ana i hangaia i Haina, ko ēnei ngā āhuatanga mahi: te pēhanga ingoa PN1760, te rahi ingoa DN151800, me te pāmahana mahi t610°C.

2. Ngā Āhuatanga o tētahitakirere kuaha

① Ngā painga o te takirere kuaha

A. He iti noa te ātete wai. Kāore te reo e whakarerekē i tōna ahunga rere ina haere mā te takirere kuaha nā te mea he tika te ara reo i roto i te tinana takirere kuaha, ka whakaiti i te ātete wai.

B. He iti noa te ātete i te wā e tuwhera ana, e kati ana hoki. Ki te whakatauritea ki te takirere porowhita, he iti ake te penapena mahi i te whakatuwheratanga me te kati o te takirere kēti nā te mea he poutū te ahunga o te nekehanga o te kēti ki te ahunga rere.

C. Kāore he herenga mō te ahunga rere o te reo. Nā te mea ka taea e te reo te rere i tētahi taha, i tētahi taha rānei o te takirere kuaha, ka taea e ia te whakatutuki i tana kaupapa i whakaritea, ā, he pai ake mō ngā paipa ka rerekē pea te ahunga rere o te reo.

D. He hanganga poto ake. He poto ake te roa o te hanganga o te takirere porowhita i te takirere kuaha nā te mea kei te whakanoho whakapae te kōpae o te takirere porowhita i roto i te tinana takirere, ko te takirere kuaha o te takirere kuaha kei roto i te tinana takirere poutū.

E. Ngā āheinga hiri whai hua. Ka iti ake te pakaru o te mata hiri ina tuwhera katoa.

② Ngā ngoikoretanga o te takirere kuaha

A. He māmā noa te whara i te mata hiri. Ka pāngia te mata hiri o te kēti me te nohoanga takirere e te waku ina tuwhera, ina kati hoki, ka ngawari te pakaru, ka whakaiti i te mahi hiri me te roa o te ora.

B. He teitei rawa, ā, he roa te wā whakatuwheratanga me te wā kati. He nui te whiu o te pereti kēti, me nui te wāhi hei whakatuwhera, ā, he teitei te rahi o waho nā te mea me tuwhera katoa, me kati katoa rānei te takirere kēti i te wā e tuwhera ana, e kati ana hoki.

He hanganga uaua, reta C. Ki te whakatauritea ki te takirere porowhita, he maha ake ngā wāhanga, he uaua ake te hanga me te tiaki, ā, he nui ake te utu.

3. Te hanganga o te takirere kuaha

Ko te tinana takirere, te taupoki, te pūmau rānei, te kakau takirere, te nati kakau takirere, te pereti kēti, te nohoanga takirere, te porowhita tākai, te tākai hiri, te repe tākai, me te taputapu tuku te nuinga o te takirere kēti.

Ka taea te hono i tētahi takirere karo (takirere aukati) i runga i ngā paipa tomo me te putanga i te taha o ngā takirere kēti whānui-rahi, pēhanga-teitei rānei, kia whakaitihia ai te taipana whakatuwheratanga me te kati. Whakatuwheratia te takirere karo i mua i te whakatuwheratanga o te takirere kēti ina whakamahia ana hei whakataurite i te pēhanga i ia taha o te kēti. Ko te whānui ingoa o te takirere karo he DN32, neke atu rānei.

① Ko te tinana takirere, e hanga ana i te wāhanga e mau ana i te pēhanga o te awa rere reo, ā, ko te tinana matua o te takirere kuaha, e piri tika ana ki te paipa, ki ngā taputapu rānei. He mea nui tēnei mō te whakatakoto i te nohoanga takirere ki tōna tūranga, te whakairi i te taupoki takirere, me te hono i te paipa. He nui te teitei o te rūma takirere o roto nā te mea me uru te kuaha āhua kōpae, he poutū, he neke ake, he neke iho, ki roto i te tinana takirere. Ko te pēhanga ingoa te mea nui e whakatau ana i te āhua o te whakawhiti o te tinana takirere. Hei tauira, ka taea te whakawhāiti i te tinana takirere o te takirere kuaha pēhanga iti kia poto ai tōna roa hanganga.

I roto i te tinana takirere, he porowhita te nuinga o ngā ara waenga. Ko te whakaitiiti he tikanga ka taea hoki te whakamahi i runga i ngā takirere kuaha he whānui te diameter hei whakaiti i te rahi o te kuaha, te kaha whakatuwhera me te katinga, me te taipana. Ina whakamahia te whakaitiiti, ka piki ake te ātete wai i roto i te takirere, ka heke te pēhanga me te pikinga o ngā utu pūngao. Nō reira, kaua te ōwehenga whakaitiiti o te awa e nui rawa. Kaua te pae pahi o te koki piko o te awa whaiti ki te rārangi pokapū e neke ake i te 12°, ā, ko te ōwehenga o te whānui o te awa nohoanga takirere ki tōna whānui ingoa me noho i waenga i te 0.8 me te 0.95.

Ko te hononga i waenga i te tinana takirere me te paipa, tae atu ki te tinana takirere me te taupoki, ka whakatauhia e te hanganga o te tinana takirere kuaha. Ko te whakarewa, te whakarewa, te whakarewa whakarewa, te whakarewa whakarewa, me te whakarewa pereti ngongo he kōwhiringa katoa mō te taratara o te tinana takirere. Mō ngā diameter i raro i te DN50, ko ngā tinana takirere whakarewa te nuinga o te wā e whakamahia ana, ko ngā tinana takirere whakarewa te nuinga o te wā e whakamahia ana, ko ngā takirere whakarewa-whakarewa te nuinga o te wā e whakamahia ana mō ngā whakarewatanga whakauru kāore e tutuki i ngā whakaritenga, ā, ka taea hoki te whakamahi i ngā hanganga whakarewa-whakarewa. Ko ngā tinana takirere whakarewa-whakarewa te nuinga o te wā e whakamahia ana mō ngā takirere he raruraru ki te tukanga whakarewa whānui.

②He pouaka whakakī kei runga i te taupoki takirere, ā, e piri ana ki te tinana takirere, koia te wāhanga matua o te rūma pēhanga e mau ana i te pēhanga. Kei te taupoki takirere ngā wāhanga tautoko mata mīhini, pērā i ngā nati kakau, ngā tikanga tuku rānei, mō ngā takirere whānui waenga me te iti.

③Ko te nati kakau, ko ētahi atu wāhanga rānei o te taputapu tuku, e tautokona ana e te whāriki, e piri ana ki te taupoki.

④E hono tika ana te kakau takirere ki te nati kakau, ki te taputapu tuku rānei. Ko te wāhanga tokotoko kua orohia me te takai he takirua hiri, ka taea te tuku i te taipana me te mahi hei whakatuwhera me te kati i te kēti. E ai ki te tūranga o te miro i runga i te kakau takirere, ka wehea te takirere kēti kakau me te takirere kēti kakau huna.

A. Ko te takirere kuaha take e ara ake ana he takirere kei waho o te kōhao tinana tōna miro tuku, ā, ka taea e tōna take takirere te neke ake, te neke iho rānei. Me huri te nati take i runga i te whāriki, i te taupoki rānei, kia taea ai te hiki ake i te take takirere. Kāore te miro take me te nati take e pā ana ki te reo, nō reira kāore e pāngia e te pāmahana me te waikura o te reo, nā reira i rongonui ai rāua. Ka taea noa e te nati take te huri me te kore e neke ake, e heke iho rānei, he mea pai mō te whakahinuhinu i te take takirere. He mārama hoki te whakatuwheratanga o te kuaha.

B. He miro tuku kei roto i te kōhao tinana o ngā takirere kuaha take pouri, ā, he kākano takirere hurihuri. Mā te hurihuri i te kākano takirere ka panaia te nati kākano ki runga i te pereti kuaha, ka piki, ka heke te kākano takirere. Ka taea anake te hurihuri e te kākano takirere, kāore e neke ake, e heke iho rānei. He uaua te whakahaere i te takirere nā te mea he iti te teitei me te uaua o te whakatuwhera me te kati. Me whakauru ngā tohu. He pai mō te reo kore-waikura me ngā āhuatanga āhuarangi kino nā te mea ka pā te pāmahana me te waikura o te reo ki te pā o te miro kākano takirere me te nati kākano me te reo.

⑤Ko te wāhanga o te takirua kinematic ka taea te hono tika ki te taputapu tuku me te taipana tuku he mea hanga mai i te nati kakau takirere me te rōpū miro kakau takirere.

⑥Ka taea te tuku tika i te hiko, te hau, te waipēhi, me te mahi ki te kakau takirere, ki te nati rānei mā te taputapu tuku. Ko te taraiwa tawhiti i roto i ngā tipu hiko ka whakamahia ngā wira ā-ringa, ngā taupoki takirere, ngā wāhanga tuku, ngā pou hono, me ngā hononga whānui.

⑦nohoanga takirere Ka whakamahia te hurihuri, te whakarewa, ngā hononga miro, me ētahi atu tikanga hei whakau i te nohoanga takirere ki te tinana takirere kia taea ai te hiri ki te keti.

⑧I runga i ngā hiahia o te kiritaki, ka taea te whakatakoto tika i te mowhiti hiri ki runga i te tinana takirere hei hanga i tētahi mata hiri. Ka taea hoki te whakatakoto tika i te mata hiri ki runga i te tinana takirere mō ngā takirere i hangaia mai i ngā rauemi pēnei i te rino maka, te maitai kore waikura austenitic, me te koranu parahi. Hei ārai i te turuturu o te wai i te taha o te kakau takirere, ka whakanohoia te takai ki roto i te pouaka whakakī (pouaka whakakī).
