Ngā wāhi tāutanga o ngā hononga taura hiko

He mea nui ngā pane o te taura me ngā hononga waenga i roto i ngā taura whakawhiti me te whakawhiti hiko. Ko tā rātou mahi he hora i te papa hiko i te wāhanga tapahi o te parepare o waho o te pane o te taura, hei tiaki i te taura mai i te pakaru, ā, he ārai ā-roto, ā-waho hoki, ā, he ārai wai hoki. I roto i ngā taura, neke atu i te 60% o ngā aituā i puta mai i ngā taputapu tāpiri, nō reira he mea nui te kounga o ngā taputapu tāpiri ki te haumaru me te pono o te whakawhiti hiko katoa.

1 Hononga arataki

He iti te ātete e hiahiatia ana mō te hononga ara iahiko, ā, he rawaka te kaha ā-ringa, ā, kaua e puta he kokonga koi i te hononga. Ko te hononga e whakamahia whānuitia ana mō ngā ara iahiko taura ngaohiko reo me te iti ko te whakapiko, ā, me aro te whakapiko ki:

(1) Kōwhiria he paipa honohono arataki me te arataki e tika ana me te kaha ā-ringa;

(2) Ko te āputa i waenganui i te diameter o roto o te ngongo whakakoi me te diameter o waho o te matua hono ko 0.8～1.4mm;

(3) Kaua te uara ātete o te hononga i muri i te whakapiko e neke atu i te 1.2 ngā wā o te ara iahiko o te wāhanga whakawhiti ōrite, ā, kaua te kaha kume o te hononga o te ara iahiko parahi e iti iho i te 60N/mm2;

(4) I mua i te whakakoi, pania te mata o waho o te ara iahiko me te mata o roto o te paipa hono ki te kāpia ara iahiko, ā, whakamahia he paraihe waea hei whakangaro i te kiriata waikura;

(5) Me whakamāeneene ngā kokonga koi me ngā kohao o te paipa hono me te ara iahiko matua ki te kōnae, ki te pepa kirikiri rānei.

2 Te maimoatanga parepare haurua-ā-roto

Mēnā he paparanga ārai o roto o te tinana taura, me whakahoki te paparanga ārai o roto o te wāhanga ara iahiko o te ngongo whakapiko ina oti te hononga, ā, me waiho tetahi wāhanga o te ārai haurua-ā-roto o te taura kia taea ai e te ārai o roto o te hononga i runga i te ngongo hono te whakawhitiwhiti kōrero. Me whakarite kia haere tonu te haurua-ā-roto o roto, kia ōrite te tohatoha o te kaha o te mara i te hononga.

3 Te maimoatanga parepare haurua-ā-waho

Ko te parepare haurua-ā-waho he rauemi haurua-arahi e mahi ana hei papa hiko ōrite i waho o te whakamarumaru o te taura me te hononga. Pērā i te parepare haurua-ā-roto, he mahi tino nui tāna i roto i te taura me te hononga. Me ātaahua, me ōrite hoki te putanga haurua-ā-waho, ā, me maeneene hoki te whakawhiti me te whakamarumaru, ā, ka tāpirihia he rīpene haurua-ā-roto huri noa i te hononga hei hono atu ki te parepare haurua-ā-roto i waho o te tinana taura.

4 Te maimoatanga o te koeko kaha tauhohenga taura

I te wā e hangaia ana, he rite tonu te horapa o te kaha o te koeko tauhohenga ki te mata katoa o te koeko. I te wā e hangaia ana te koeko tauhohenga taura whakawhiti-hono, ka whakamahia he taputapu tapahi motuhake, ka taea rānei te whakamahana mā te ahi iti ka mahia ki te maripi koi. I muri i te tapahi me te hanga taketake, whakamahia he karāhe matotoru 2mm hei waru, ā, i te mutunga, whakamahia he pepa kirikiri hei whakakanapa mai i te matotoru ki te angiangi kia maeneene.

5 Te ārai whakarewa me te maimoatanga whenua

Ko te mahi matua a te parenga whakarewa i roto i ngā taura me ngā hononga ko te kawe i ngā iahiko poto o te taura me te tiaki i te pokanoa hikohiko mai i ngā mara hikohiko i runga i ngā taputapu whakawhitiwhiti tata. I te wā e mahi ana, kāore he pūmanawa o te parenga whakarewa i roto i te āhua whenua pai. Ina pakaru te taura, ka taea e ia te kawe i te iahiko poto i roto i te wā poto rawa. Me whakapiri pono te waea whenua, me whakapiri pūmau ngā parenga whakarewa me ngā rīpene pukupuku i runga i te tinana taura o ngā pito e rua, ā, me pono te whenua o te pane pito.

6 Te hiri me te tiaki ā-pūkaha o ngā hononga

Ko te hiri me te tiaki ā-pūkaha o te hononga te taurangi hei whakarite i te haumaru me te pono o te mahi o te hononga. Āraihia te urunga o te makuku me te haumākū ki roto i ngā hononga, ā, hangaia he awaawa tiaki hononga, tāutahia rānei he pouaka tiaki sima ki ngā hononga.
