Tikanga wiri tika me te tikanga o te raima

He aha te wiri raima?

Ko te wiri i te raima ka mahia hei whakapūmau. Ko te whāinga matua o te wiri ko te whakapūmau i te raima me te whakatutuki i te matotoru rawa o te raima. Tata ki te 5 ki te 8% o te rōrahi o te raima hou kua whakatakotoria i roto i te āhua e nohoia ana e ngā mirumiru hau. Kei roto i tēnei wāhi ngā mirumiru hau i roto i te ranunga raima tino pai te mahi.

Te wiri o te raima

Te take me te pēhea o te whakakotahi i te raima

Ko tēhea āhuatanga he nui ake te pānga ki te kaha pēhi o te raima i tētahi atu? E ai ki te nuinga o ngā miihini, ko te ōwehenga wai-sima…i te mea ka piki ake te ōwehenga wai-sima, ka heke te kaha. I whakaaturia tēnei e Duff Abrams i te tau 1919, ā, ko te ture a Abram te mātāpono i muri i te nuinga o ngā tikanga ōwehenga raima e whakamahia ana i ēnei rā. Engari i whakahaerehia e Abtams āna whakamātautau ki te raima kua tino whakapūmau. Ki te kore te raima e whakapūmau tika, ka whakaitihia te kaha e ngā āputa ahakoa te ōwehenga wai-sima. Ā, e whakaaturia ana i te Pikitia 1, he nui te pānga.

I muri tonu i te whakatakotoranga, kei roto i te raima te 20% o te hau kua mau. Ka rerekē te nui i runga i te momo ranunga me te hinganga, te rahi me te āhua o te āhua, te nui o te maitai whakapakari, me te tikanga whakatakotoranga raima. I te ōwehenga wai-sima pumau, ka whakaitihia e ia ōrau o te hau te kaha pēhi mā te 3% ki te 5%. Mā te whakapūmau i te raima, mā te wiri, ka whakanui ake i te kaha o te raima mā te pei atu i te hau kua mau. Ka whakapai ake hoki i te kaha piri me te whakaiti i te urunga o te raima.

He tukanga wāhanga-rua te wiri

Me pēhea te whakaū i te raima mā te wiri? E whakaatu ana te Pikitia 2 he tukanga wāhanga-rua. Ka hangaia e te wiri ngā ngaru e wehewehe ana i ngā matūriki kirikiri. Mā tēnei ka whakaiti i te waku i waenganui i a rātou.

Pikitia 1. Ka rite te pānga o te kaha whakapūmau ki te ōwehenga wai-sima ki te kaha pēhi. Tērā pea ka 20% te hau kua mau i roto i te raima iti-heke ina whakatakotoria.

Pikitia 2. Ka whakakoi te raima i roto i tētahi tukanga wāhanga-rua e te wiri. Ka whakawaiwai ngā ngaru tuatahi i te raima kia pai ake ai te rere, ā, ka pakaru ngā mirumiru hau e ngā ngaru tonu.

TIKA

Mā te kuhu poutū i ētahi inihi ki roto i te hikitanga o mua (kaua e pakari) o ngā wā auau pūnaha ka rawaka te whakau.

KA WHAKATŪTURU

Mā te werohanga matapōkere o te wiri i ngā koki me ngā mokowā katoa me te kore e ranea te hohonu e kore e whakarite kia piri pai te hononga o ngā paparanga e rua.

Ka taea te tango i ngā mirumiru hau mā te whakaiti i te nui o te wai e hiahiatia ana, engari ka pā ki te mahi a te raima. Nō reira, ko te wiri o te raima anake te tikanga tika hei āwhina me te kore e pā ki te ngā āhuatanga o te raima hou. Ka pāngia anake te wiri i roto i te raima hou, tae noa ki te wā e rere ai te raima. Kei mua i te tīmatanga o te taunga tuatahi tēnei wāhanga.

E rima ngā tikanga e taea ai te whakakīkī i te raima, te wiri rānei i te raima:
1- Te wiri i te raima ki roto mā te whakauru i tētahi wiri ā-roto ki roto i te papatipu raima.
2- Te wiri i te raima i te wā e mau ana te kati mā te whakamahi i ngā wiri hanganga o te kati.
3- Mā te wiri i te papatipu raima katoa mā te whakamahi i tētahi tēpu wiri.
4- Te wiri i te raima ki waho i te mata mā te whakamahi i ngā wiri mata.
5- Te wiri i te raima mā te whakamahi i ngā rūrū rebar.

Te wiri o te raima Ngā Tohutohu
1- Kaua e wiri rawa te raima, nā te mea ka pakaru, ka wehe te ranunga. Kaua hoki e wiri rawa te raima, nā te mea tera pea kei te mau tonu te hau i roto i ngā paparanga o raro o te ringihanga sima, ka ngoikore ai te hanganga raima, ka pakaru ngāwari ahakoa te iti o te pēhanga.
2- Ko te tikanga tino noa mō te whakamahi i te wiri ā-roto ko te tango mārire i te wiri, i te tere o te 25mm inihi ia hekona. Mena kei te puta tonu mai ngā mirumiru i te tangohanga o te wiri raima, me nui ake te wiri.
3- Hei ārai i ngā hononga makariri ki ngā paparanga raima i te wā e ringihia ana ki runga ki ēnei he paparanga hou o te ranunga sima, kia tino uru te ranunga ki roto i te ringihanga mā te whakamahi i te wiri, ā, whakaranua te paparanga i ringihia i mua ki te paparanga hou.
4- Mō te tino whai huatanga, whakamahia ngā nekehanga poutū anake i te wā e wiri ana kia ōrite te ranunga o te kirikiri me te raima. Ka taea e te nekehanga whakapae te arahi ki te tohatoha kore taurite, ā, ka nui ake te tūponotanga o te wiri e raranga ana i roto i te rino whakakaha, i te rino whakakaha rānei.
5- Kaua e whakamahi i te wiri hei taputapu whakatakoto raima nā te mea kāore e puta he mata ōrite, ā, ka nui ake pea ngā raruraru o te kaha me te āhua o te hanganga.
6- Whakamahia te momo wiri raima e tika ana, i runga i te hanganga e hangaia ana, i te rahi rānei o te wāhi mahi. Whakaarohia te whakamahi i tētahi wiri raima māmā kiato mō ngā mahi iti ake kia māmā ai te whakahaere me te whai hua.
7- Whakaarohia he tārua wiri raima kei te wātea hei whakakapi i tētahi atu taputapu mēnā ka pā mai he raruraru ki te taputapu tuatahi i a ia e mahi ana.
