He mea nui te tūhono tika ki te whenua o te tāutanga mita rere hikohiko. Nā te mea he iti noa te tohu hiko e inehia ana e te mita rere hikohiko i hangaia e te nekehanga o te wai kawe hiko mā roto i te papa aukume, ka pāngia te pumau o te ine e te pokanoa hiko o waho, te pūmanawa tohutoro kore pumau rānei.
Ka whakamahia ngā mowhiti whenua me ngā irahiko whenua hei whakarite kia ōrite te pūmanawa hiko o te wai, te tinana pūoko, me te paipa, kia pumau ai te tohutoro ine me te whakaiti i te haruru tohu.
He aha te take e hiahiatia ai te whakapūmau whenua mō te mita rere hikohiko?
Ko te mahi a te mita rere hikohiko i runga i te Ture a Faraday mō te Whakaoho Hikohiko. I te wā e ine ana, he iti noa te tohu ngaohiko e whakaputaina ana i waenga i ngā irahiko, he torutoru mirivolts noa iho.
Nā te mea he tino tairongo te tohu ine, ka pāngia pea ngā mita rere hikohiko e:
* Ngā iahiko hiko e rere ana i roto i te paipa
* Te haruru hiko mai i ngā motuka, i ngā kaitahuri auau rānei
* Ngā āhuatanga whenua kino
* Ngā rauemi paipa kore-arataki
* Ngā pūnaha tiaki katote
Ki te kore e tika te whenua, ka kore pea te tohu rere e pumau, ka puta ai:
* Te piki me te heke o te whakaaturanga rere
* Kore hē te pūwāhi
* Ngā hapa ine
* Ngā tohu putanga kore pumau
Nō reira, he mea nui tētahi pūnaha whenua pono mō te mahi tika me te pumau.
Kei hea te wāhi e tika ana kia tāutahia ai ngā mowhiti whenua?
I te nuinga o te wā ka tāutahia ngā mowhiti whenua i waenganui i te flange mita rere me te flange paipa.
Me whakanoho te mowhiti whenua kia pā tika ki te wai kawe hiko, kia honoa hoki mā te hiko ki te pito whenua o te mita rere.
Ko te tukanga tāutanga noa ko:
1. Whakatakotoria te mowhiti whenua ki waenganui i te flange pūoko me te flange paipa.
2. Kia tino mohio kei te taupokina e te hiri te mata o te mowhiti whenua e pa ana ki te wai.
3. Honoa te mowhiti whenua ki te pūnga whenua i runga i te mita rere hikohiko mā te whakamahi i te waea whenua.
4. Honoa te pūnaha ki tētahi pūwāhi whenua pono.
Āhea te wā e hiahiatia ai ngā mowhiti whenua?
E tino taunakihia ana kia whakamahia ngā mowhiti whenua i roto i ēnei āhuatanga e whai ake nei:
1. Ngā Paipa Kore-Arahi
Mena he mea hanga te paipa ki ngā rauemi penei:
* PVC
* PP
* Paipa kua whakakikoruatia ki te PTFE
* Paipa kua whakakikoruatia ki te rapa
* Kirihou whakakaha muka karāhe (FRP)
kāore e taea e te paipa tonu te whakarato i tētahi hononga hiko pono.
I ēnei āhuatanga, me whakamahi ngā mowhiti whenua hei whakatū i tētahi tohutoro hiko pumau i waenga i te wai me te mita rere.
2. Ngā Whakamahinga Paipa Kirihou
He mea noa te whakamahi i ngā paipa kirihou mō te maimoatanga wai, te tukatuka matū, me ngā mahi ahumahi.
Nā te mea he ārai hiko ngā rauemi kirihou, ka wehea pea te wai i roto i te paipa mai i te pūoko hiko. Mā te tāuta i ngā mowhiti whenua ka taea te whakakore i tēnei raruraru.
3. Ngā tono me te pokanoa hiko
I roto i ngā taiao ahumahi me:
* Ngā mōtini nunui
* Ngā papu
* Ngā puku auau rerekē (VFD)
* Ngā taputapu whakarewa
Ka taea e ngā mowhiti whenua te whakaiti i te pokanoa hiko me te whakapai ake i te pumau o te ine.
Kei hea te wāhi e tika ana kia tāutahia ai ngā hiko whakawhenua?
I te nuinga o te wā ka tāuta tika ngā irahiko whenua ki runga i te tinana o te pūoko mita rere hikohiko.
Kua hangaia ēnei hei whakarato i tētahi tohutoro hiko pumau i waenga i te wai me te pūoko.
I runga i te hoahoa o te mita rere, ko ngā irahiko whenua ka:
* Kua hangaia ki roto i te tinana o te pūoko.
* Kua tāutahia hei wāhanga whenua motuhake.
* Kua honoa ki ngā irahiko tohutoro.
Me whakanoho ngā irahiko whenua kia pa ki te wai tukatuka, ā, me hono ki roto, ki waho rānei, e ai ki te hoahoa a te kaihanga.
Te Rerekētanga i waenga i ngā Mowhiti Whakatakoto Whenua me ngā Irahiko Whakatakoto Whenua
He rite tonu te mahi a ngā mowhiti whenua me ngā hiko whenua, engari e whakamahia ana i ngā āhuatanga rerekē.
Ko ngā irahiko whenua he wāhanga o te pūoko mita rere, ā, e whakarato ana i te pūmanawa tohutoro tika mai i te wai.
Ko ngā mowhiti whenua he taputapu tāpiri e tāutahia ana i waenganui i te mita rere me te paipa, e whakamahia ana i te nuinga o te wā ina kore e taea e te paipa te whakarato i te whenua tika.
I roto i te nuinga o ngā tono paipa whakarewa paerewa, tera pea kua rawaka ngā hiko whakawhenua. Heoi, mō ngā paipa kirihou, ngā paipa kua whakarārangihia rānei, he maha ngā wā ka tūtohuhia kia whakamahia ngā mowhiti whakawhenua.
Ngā Tohutohu Tāutanga mō te Whakatakotoranga Whenua
Hei whakatutuki i te mahi ine pono, whai i ēnei aratohu:
1. Whakamahia he Hononga Whenua Motuhake
Me hono te mita rere ki te whenua pono mā te whakamahi i tētahi taura whenua tika.
Kaua e whakawhirinaki ki:
* Ngā tautoko paipa
* Ngā flange anake
* Ngā hanganga whakarewa tata
hei ara whenua.
2. Kia iti te ātete whenua
Me iti te ātete hiko o te hononga whenua kia pumau ai te pūmanawa tohutoro.
Mā te koretake o te whenua ka puta:
* Te piki me te heke o te tohu
* Te kore pumau o te putanga
* Te pokanoa ki te whakawhitiwhiti kōrero
3. Kaua e Whakawhitiwhiti i te Whenua me ngā Taputapu Mana-Nui
Me karo te pūnaha whenua mita rere i te whakamahi i te pūwāhi whenua kotahi me ngā taputapu e whakaputa ana i te haruru hiko, pēnei i:
* Ngā Motuka
* Ngā Kaitahuri
* Ngā mīhini whakarewa
He pai ake te whakamahi i tētahi pūwāhi whenua motuhake i roto i ngā taiao ahumahi.

4. Kia Aro ki ngā Paipa Tiakina e te Katorika
Ka whakamahia e ētahi paipa ngā pūnaha tiaki katote hei ārai i te waikura.
I roto i ēnei tono, ka taea e ngā hononga whenua tika te waihanga i ngā ara iahiko kāore e hiahiatia, ā, ka pā ki te tika o te ine.
Tērā pea e hiahiatia he tikanga tāutanga motuhake, pērā i te wehewehe hiko i waenga i te mita rere me te pūnaha whenua o ngā paipa.
Te Whakatakotoranga Whenua mō ngā Rauemi Paipa Rerekē
Mō ngā paipa whakarewa:
* He pai te haere tonu o te hiko i roto i te paipa.
* Tērā pea he rawaka ngā irahiko whenua mēnā kua tika te whenua o te paipa.
Mō ngā paipa kirihou:
* He tino taunaki kia whakamahia ngā mowhiti whenua.
* Kāore e taea e te mita rere te whakawhirinaki ki te paipa mō te tohutoro hiko.
Mō ngā paipa whakarara:
* Tirohia mēnā kei te ārai hiko te papanga arai.
* Whakamahia ngā mowhiti whenua mēnā kua wehea te wai mai i te paipa mā te hiko.
Ngā Raru me ngā Otinga o te Whenua Noa
Raru: Ka rerekē te tohu rere i muri i te tāutanga
Ngā take pea:
* Hononga whenua ngoikore
* Te pokanoa hiko
* Kāore he mowhiti whenua e tāutahia ana ki ngā paipa whakamahana
Otinga:
* Tirohia te ātete o te whenua.
* Manatokohia te hononga taura whenua.
* Tāutahia ngā mowhiti whenua mēnā e hiahiatia ana.
Raru: Kei te mahi noa te mita rere i roto i te wheketere engari kāore i te pumau i te papaanga
Ngā take pea:
* Ngā āhuatanga rerekē o te whenua o te pae.
* Te pokanoa mai i ngā papu, i ngā kaitahuri auau rānei.
* Tikanga whakawhenua hē.
Otinga:
* Whakapai ake i te hononga whenua.
* Tāutahia he pūwāhi whenua motuhake.
* Wehea te mita rere mai i ngā taputapu hiko haruru.
He mea nui ngā mowhiti whenua me ngā irahiko whenua ki te whakarite i te ine tika me te pumau o te rere hikohiko.
Ko ngā irahiko whenua ka tāutahia ki runga i te pūoko mita rere hei whakarato i te pūmanawa tohutoro tika mai i te wai. Ka tāutahia ngā mowhiti whenua i waenganui i te flange mita rere me te flange paipa, inā koa ka whakamahia ngā paipa kore-arataki, ka hiahiatia rānei he tiaki whenua tāpiri.
Mā te whakatū whenua tika ka āwhina i te whakaiti i te pokanoa hiko, ka whakau i ngā tohu ine, ā, ka whakarite kia roa te whakamahi pono o ngā mita rere hikohiko.
