He aha te rerekētanga i waenga i te mekameka roera me te whitiki taraiwa i roto i te tiaki?
Anei ngā rerekētanga tiaki i waenga i te mekameka roera me te whitiki taraiwa:
1. Ngā ihirangi tiaki
Mekameka roera
Te whakarite i te porotiti: Me whakarite kia tāuta te porotiti ki runga i te pou, kia kore e piko, e piu, ā, me whakanoho ngā mata o ngā porotiti e rua i roto i te huihuinga tuku kotahi ki te papa kotahi. Mēnā he iti iho i te 0.5 mita te tawhiti o te pokapū porotiti, ko te rerekētanga e whakaaetia ana he 1 mm; mēnā he nui ake i te 0.5 mita te tawhiti o te pokapū porotiti, ko te rerekētanga e whakaaetia ana he 2 mm. Mēnā he nui rawa te rerekētanga o te porotiti, ka ngāwari te pakaru o te mekameka me te tere o te kakahu. Hei tauira, i te wā e whakakapi ana, e tāuta ana rānei i te porotiti, me āta whakatikatika te tūranga o te porotiti, ā, whakamahia ngā taputapu ine motuhake hei whakarite i te tika o te whakarite o te porotiti.
Te whakatikatika i te pūmau o te mekameka: He mea tino nui te pūmau o te mekameka. Hiki ake, pēhia rānei ki raro mai i waenganui o te mekameka, kia 2% – 3% o te tawhiti pokapū i waenga i ngā porotiti e rua te pūmau tika. Ki te pūmau rawa te mekameka, ka nui ake te whakapaunga hiko, ā, ka ngāwari te pakaru o ngā peera; ki te tino wetekina, ka ngāwari te peke me te heke te mekameka. Me tirotiro tonu te pūmau o te mekameka, me te whakatikatika kia rite ki te āhuatanga tūturu, pērā i te whakarerekē i te tawhiti pokapū, te whakamahi rānei i tētahi taputapu whakatōtika.
Te Whakahinuhinu: Me pupuri tonu kia pai te whakahinuhinu o ngā mekameka roera i ngā wā katoa. Me tohatoha te hinu whakahinuhinu ki te āputa o te mekameka hononga i roto i te wā tika, me te ōrite. Kāore i te tūtohutia kia whakamahia he hinu taumaha, he hinu matotoru rānei, nā te mea ka ngāwari te ārai i te āputa hononga ki te puehu. Me horoi, me whakakore hoki i te poke o te mekameka roera i ia wā, ā, me tirotiro te pānga whakahinuhinu. Hei tauira, mō ētahi mekameka roera e mahi ana i roto i ngā taiao kino, me tirotiro pea te whakahinuhinu i ia rā, me te whakakī anō i te hinu whakahinuhinu i te wā tika.
Tirotiro i te pakaru: Tirohia te mata mahi o ngā niho o te porotiti i ngā wā katoa. Mēnā ka kitea he tere rawa te pakaru, whakatikatikahia, whakakapia rānei te porotiti i te wā tika. I taua wā anō, tirohia te pakaru o te mekameka, pērā i te mea kua hipa te roa o te mekameka i te awhe e whakaaetia ana (i te nuinga o te wā, me whakakapi te mekameka mēnā kua neke atu te roa o te mekameka i te 3% o te roa taketake).
Puku whitiki
Te whakatikatika i te kume: Me whakatikatika anō hoki te whitiki i te kume i ia wā. Nā te mea ehara te whitiki i te tinana tino pīngore, ka whakangāwari i te āhua kirihou ina mahihia i roto i te āhua kume mō te wā roa, ka whakaiti i te kume tuatahi me te kaha tuku, ā, ka paheke pea i ngā wā kino. Ko ngā tikanga kume noa ko te kume auau me te kume aunoa. Ko te kume auau ko te whakanui ake, te whakaiti rānei i te tawhiti pokapū mā te whakatikatika i te tīwiri kia tae atu ai te whitiki ki te kume tika. Ka whakamahia e te kume aunoa te taumaha mate o te motuka, te kaha puna rānei o te wira kume hei whakatikatika aunoa i te kume.
Tirotiro tika o te tāutanga: Ina peia ngā toki whakarara, me pupuri tonu ngā toki o ia pūreirei i te whakarara kua tohua. Me whakarite ngā awaawa o ngā wira peia me ngā wira peia o te puku whitiki-V i te papa kotahi, ā, kaua te hapa e neke ake i te 20′, ki te kore ka takahuri te whitiki-V, ka pakaru wawe i ngā taha e rua. I te wā tāutanga me te tiaki, whakamahia ngā taputapu pēnei i te taumata hei tirotiro i te whakarara o te toki me te whakarite o ngā awaawa.
Te whakakapi me te taurite i te whitiki: Ina kitea he whitiki-V kua pakaru, me whakakapi i te wā tika. Kāore e taea te whakaranu i ngā whitiki hou me ngā whitiki tawhito, ngā whitiki-V noa me ngā whitiki-V whaiti, me ngā whitiki-V o ngā whakatakotoranga rerekē. Heoi anō, ina whakahaerehia he whitiki-V maha, kia kore ai e taurite te tohatoha kawenga o ia whitiki-V, me noho te manawanui taurite o te whitiki ki roto i te awhe kua tohua. Hei tauira, i te wā e whakakapi ana i te whitiki-V, tirohia marietia te tauira me ngā whakatakotoranga o te whitiki kia rite te rahi o te whitiki hou ki te whitiki tawhito, ā, i te wā e tāuta ana i ngā whitiki maha, kia rite te piripono.
2. Auautanga tiaki
Mekameka roera
Nā te nui o te whakahinuhinu e hiahiatia ana mō ngā mekameka roera, inā koa i te wā e mahi ana i ngā taiao uaua, me tirotiro pea te whakahinuhinu me te whakakī anō i ia rā, i ia wiki rānei. Mō te piripono o te mekameka me te tūnga o te porotiti, e taunakihia ana kia tirohia kotahi i te marama. I ētahi taiao mahi kaha, me tirotiro pea te roa o te mekameka me te pakaru o te porotiti i ngā wā maha atu, pērā i te kotahi i ia rua wiki.
Puku whitiki
He iti noa te auau o te tirotiro i te kukū o te puku whitiki, ā, ka taea te tirotiro kotahi i te marama. Mō te mau o te whitiki, ki te mea he taiao mahi noa, ka taea te tirotiro kotahi i te hauwhā. Heoi, ki te mea he nui te kawenga o te puku whitiki, he maha rānei ngā āhuatanga tīmata-mutu, me whakanui ake pea te auau tirotiro ki te kotahi i te marama.
3. Te Uauatanga o te Tiaki
Mekameka Roera
He tino uaua te tiaki i te pūnaha whakahinuhinu, inā koa mō ētahi taputapu tuku mekameka roera e whakamahi ana i te whakahinuhinu kaukau hinu, i te whakahinuhinu pēhanga rānei. Me horoi tonu ngā poke o te pūnaha whakahinuhinu, me te whakarite kia hiritia te pūnaha whakahinuhinu. Ko te whakarite i te porotiti me te whakatikatika i te kukū o te mekameka me whai mātauranga hangarau me ngā taputapu anō hoki, pērā i te whakamahi i ngā taputapu whakarite porotiti me ngā mita kume hei whakatikatika tika.
Puku Whitiki
He māmā noa te tiaki i te whitiki taraiwa, ā, he māmā noa te whakarite i te taputapu whakapūmau. He watea hoki te whakakapi i te whitiki. Tangohia noa te whitiki pakaru kia rite ki ngā mahi kua whakaritea, tāutahia te whitiki hou, ka whakatikatika i te whakapūmau. Heoi anō, he māmā noa te hanganga o te whitiki taraiwa, ā, i te nuinga o te wā, kāore he taputapu me he taputapu uaua e hiahiatia ana hei whakaoti i te tiaki o ia rā.
