TL;DR

Kua kite ā-kanohi mātou i ngā mea ka puta ina kore e tino whakamāramahia te whenua o te taiepa hiko. I roto i ā mātou tau 17 e hanga ana i ngā pou whenua me ngā tokotoko whenua, ko ngā hapa tino taea te ārai ka ahu mai i te korenga o te whiriwhiri rauemi pou i te wā hoko.

He aha te take e whakatau ai te whakatikatika tika i te mahi a te taiepa

Ina pā te kararehe ki tētahi waea taiapa ora, ka oti te ara iahiko mā roto i te tinana o te kararehe, mā roto i te oneone, ka hoki anō ki te tokotoko whenua taiapa hiko e hono ana ki te pūwhakaoho i tohua e mātou. Mēnā kāore e taea e taua tokotoko whenua te tuku i te iahiko ki roto i te whenua e karapoti ana, ka heke te ngaohiko i te taiapa, ā, ka ngoikore te wiri o te kararehe. Kua whakamatauria e tā mātou wheketere ngā rau o ngā whirihoranga whenua puta noa i ngā momo oneone rerekē, ā, ka puta anō te tauira i ia wā: ko te pou whenua kāore i te tino tohua te tino take nui o te ngoikore o te mahi a te taiepa.

I tō mātou whare hanga i Xinchang, ka hangaia e mātoungā pou whenua parahi parakoreko ngā diameters mai i te 12 mm ki te 20 mm me te roa mai i te 1.2 m ki te 3 m. Neke atu i te 17 tau o te hanga, kua tukuna e mātou ngā hiko whenua ki ngā kaituku ahuwhenua i roto i te 40+ whenua, ā, ko ngā urupare e kohia ana e mātou e whakaatu tonu ana i tētahi kitenga: ko ngā kaituku e tohu ana i ngā titi whenua parahi i runga i ngā raraunga oneone kua tuhia he iti ake ngā hokinga mai o ngā hua me te kaha ake o te pono o ngā kiritaki whakamutunga i te hunga e whiriwhiri ana i runga i te utu anake.

E ai ki tePūtake raraunga whakaputa ahuwhenua a te FAO, kei te piki haere tonu ngā taupori kararehe o te ao, e akiaki ana i te hiahia mō ngā hanganga taiapa pono. Mai i ō mātou wheako whakaputa, ko ngā kaituku e mārama ana ki te pūtake hangarau o te whenua e tū ana hei kaiwhakarato tohutohu kaua hei kaihoko taonga, ā, ko taua rerekētanga ka puta tika ki te pupuri i ngā kiritaki.

Kei roto i ā mātou hua he parahi parakore, he parahi-whakakikoruatia, me ngā pou oneone kua whakakikoruatia, nā te mea he rerekē te otinga mō ia āhua oneone me ia tahua. Ka āwhina mātou i ngā kaituku ki te whakataurite i ngā rauemi tika ki tā rātou mākete.

Parahi Parakore vs. Tokotoko Parahi-Kākahuhia vs. Tokotoko Pirau: He Whakataurite Rauemi

E toru ngā momo tokotoko e hangaia ana e mātou, nō reira ko tā mātou tirohanga ki te whiriwhiri rauemi i ahu mai i te wheako whakaputa tika, kaua i te whakaaro noa i runga i te rarangi pukapuka. He wāhi tō ia rauemi i te mākete, ā, ka taea e te kaituku e kawe ana i ngā kōwhiringa e toru te mahi ki tētahi turanga kiritaki whānui ake. Ka hangaia e mātou Kei te ripanga i raro nei ngā āhuatanga e whai tikanga ana mō ngā tono pou whenua taiepa hiko.

E whakaatu ana ā mātou raraunga whakaputangā tokotoko whenua whakakikoruatia ki te parahikei roto i tētahi ara waenga e hē ana te mārama o ētahi kaihoko. He rerekē te whakakikorua i te whakakikorua: he angiangi ake tā mātou paparanga parahi (i raro iho i te 0.1 mm te matotoru) ā, he iti ake te tiaki. Ka whakamārama tonu mātou i tēnei rerekētanga ki ngā hoa tohatoha nā te mea ko te he o te tapanga i tētahi tokotoko whakakikoruatia hei whakakikorua ka arahi ki ngā amuamu ina kore e angitu tā mātou hua i roto i te oneone waikawa. Mena ka mahi pāmu ō kaihoko i ngā rohe he pH oneone kūpapa, ā, e hiahia ana koe ki tētahi kōwhiringa whakataetae-utu, ka tohutohu mātou i a rātou ki tā mātoungā tokotoko whenua whakakoi or ngā tokotoko whenua piauau wera, e tuku ana i te mahi pakari i te utu iti iho.

Mō ngā pae he nui ake ngā tono, ko tekāwai tokotoko whenua parahi parakorekei roto i tā mātou rārangi pukapuka te whānuitanga katoa o ngā diameter me ngā roa. Ka hangaia hoki e mātoungā tokotoko whenua kua whakakikoruatia ki te parahimō ngā kaituku e hiahia ana ā rātou kiritaki ki te taurite o te utu me te kawe hiko. Ka arotakehia e tā mātou tīma hangarau ia oma whakaputanga ki ngā whakaritenga e tika ana i mua i te tukunga o ngā taonga, ā, ka pupuri mātou i ngā tuhinga kounga taipitopito e whai ake nei ki ngā tiwhikete rauemi mata.

Ka hangaia e mātou he pou oneone parahi parakore, ko te whānui mai i te 10 mm ki te 20 mm, ā, ko te roa mai i te 1 mita ki te 3 mita. Ko ngā ine i raro nei e whakaata ana i ngā mea e tohua ana e ō mātou hoa tohatoha ahuwhenua mō ngā mahi taiepa hiko.

Te Tauwhāiti i te Roa o te Tokotoko, te Diameter, me te Wāhanga Whakawhiti

E rua ngā tawhā ā-tinana e ārahi ana i te ātete whenua: ko te horahanga pa o te tokotoko ki te oneone me te ātete papatipu o te oneone. Mā te whakanui ake i te roa, i te whānui rānei o te pou whenua parahi ka whakaiti i te ātete, engari ko te roa ka nui ake te hokinga mai mō ia waeine o te utu rauemi. Koia te take e pai ake ai ā mātou whakaritenga ki ngā tokotoko i waenga i te 1.5 m me te 2.4 m, kaua ki ngā hoahoa ngako poto.

Ko ngā rahi paerewa e hangaia ana e tā mātou wheketere e whai ake nei, ā, ka taea e mātou te whakarite i ngā roa ritenga ina tonoa mai:

• 12 mm x 1.2 m – Ngā pāmu kāinga me ngā pāmu whakangahau iti
• 14 mm x 1.5 m – Ngā mahi kararehe tauine waenga (ko tā mātou SKU whiriwhiri paerewa)
• 14 mm x 2.0 m – Taiapa arumoni paerewa i roto i ngā oneone paru
• 16 mm x 2.4 m – He whenua whāngai kararehe nui me ngā rohe maroke-haurua
• 20 mm x 3.0 m – Ngā pūngao kaha-teitei mō ngā whakaurunga tauine pāmu

Ina tohua hetokotoko whenua taiepa hikomō te tohatoha, ka tohutohu mātou ki ō mātou hoa mahi kia rua ngā roa o te rakau: he rakau 1.5 m mō ngā rakau whānui, me te rakau 2.4 m mō ngā kaihoko i ngā rohe iti te ua. Mā te hono i ēnei kihononga tokotoko whenua parahika taea e ngā kaiwhakauru te hono i ngā wāhanga e rua mō te hohonu ake me te kore e tono tokotoko roa motuhake ka piki ake te utu kaipuke.

Ka arotakehia e tā mātou tīma hangarau ngā raraunga ātete oneone mō ia rohe kaupapa hou ka tomo mātou. Ko ngā aratohu i raro nei i ahu mai i ō mātou wheako mara puta noa i ngā whenua e rima.

Ngā Āhuatanga Oneone me te Hoahoa Pūnaha Whenua

Ka rerekē te ātete oneone i runga i te nui o te makuku, te hanganga kohuke, me te pāmahana. Kua mahi tahi mātou me ngā kaituku e mahi ana ki ngā pāmu i te takutai moana o New South Wales (Ahitereiria) kei reira te oneone kua whakanuia ki te tote e 20 ohm-mita te rehita, me ngā hoa mahi e tuku ana i ngā pāmu i waenganui o Texas kei reira te oneone onepu maroke e neke ake ana i te 500 ohm-mita. Ko te tokotoko whenua taiepa hiko kotahi e mahi pai ana i te taiao tuatahi ka pakaru i te tuarua mena kaore te kaihoahoa pūnaha e whakaaro ki te ātete.

E toru ngā momo oneone e hangaia ana e tā mātou tīma:

Ātete iti (i raro i te 100 ohm-m): Ngā oneone momona i te uku, ngā oneone makuku rānei. Mai i ā mātou wheako whakaputa, e rua ki te toru ngā tokotoko parahi parakore, 1.5 m te roa, e 3 m te tawhiti, ka eke ki te ātete whainga i raro i te 10 ohm mō ngā pūkaha tae atu ki te 6 joule.

Ātete waenga (100-300 ohm-m): He oneone maroke ā-wā. Mai i ā mātou wheako whakaputa, e toru ki te rima ngā rākau i te 2.0 m te roa, me te whakakotahi me te whakatikatika oneone (te whakakī bentonite) mēnā e tika ana. Ka taea e tā mātou wheketere te whakarato i te ranunga whenua kua oti te whakaranu ki runga papa i te taha o ngā rākau hei whakahaere i ngā mahi a ō kaihoko.

Te ātete teitei (neke atu i te 300 ohm-m): Ngā oneone onepu, toka, maroke rānei. E ono, neke atu rānei ngā tokotoko i te 2.4 m, neke atu rānei, he whakawhiti rānei ki ngā irahiko whenua matū. Ka hangaia e mātou ngā irahiko whenua matū mō ēnei āhuatanga, ā, ka taea e mātou te matapaki i ngā whirihoranga ritenga mā roto i ā mātourōpū tautoko hangarau.

Kei roto i a mātou ngā aratohu tāutanga mō ia tukunga nā te mea ka pā tika te tikanga taraiwa tika ki te roa o te wā e whakamahia ana te pou. Ko ngā tikanga kei raro nei ko ngā mea e whaihia ana e ā mātou tohunga hangarau o te mara.

Ngā Whakatakotoranga e Manakohia ana mō te Tāutanga mō ngā Wāhi Ahuwhenua

E rua ngā wā i te tau ka toro atu mātou ki ngā pāmu me ō mātou hoa tohatoha, ā, ko ngā hapa tāutanga tonu te tuarua o ngā pūtake nui o ngā amuamu mō te whenua (whai muri i te kore e tika te whakaritenga). Kei te rārangi arowhai e whai ake nei ngā mea e whakaakona ana e tā mātou tīma hangarau mara i aua haerenga.

Taraiwa poutū, kaua i te koki. Ko te tokotoko e koki ana i te 30 nekehanga ki te poutū he 15% te iti iho o te hohonutanga whai hua, ā, ka kohia te makuku o te mata, kaua e tae ki te paparanga oneone pumau. Whakamahia he taupoki taraiwa hei tiaki i te miro o runga o te tokotoko i te wā tāutanga.

Whakatakotoria he tawhiti kia rua te roa o ngā tokotoko. Mō ngā tokotoko 2.0 m, kia 4 m te iti rawa. Mā te whakakīkī i ngā tokotoko ka puta he rohe ātete taupatupatu, ā, ka moumou rauemi, engari kāore e whakaiti i te ātete o te pūnaha.

Mena e tika ana, tāutahia ki te taha o tētahi puna wai. Ko ngā tokotoko e whakatakotoria ana i roto i te 5 m o tētahi awaawa, tāpoi wai, wāhi whakamakuku rānei, ka whai hua mai i te makuku oneone nui ake i te tau katoa. Mā te whakatau whakatakoto kotahi ka taea te whakaiti i te maha o ngā tokotoko e hiahiatia ana ki te haurua.

Whakakīia ki te matū kawe hiko i ngā rohe maroke. Mā te takai i te tokotoko ki te bentonite, ki tētahi atu whakakī hiko motuhake rānei, ka nui ake te whānui whai hua, ā, ka mau tonu te pānga o te makuku i ngā wā maroke. Ka tukuna e mātou ngā rauemi whakakī ki roto i ngā putea 25 kg ka tukuna i runga i te papa kotahi me ngā tokotoko.

Te Hononga i ngā Tūāpapa Whenua ki te Energizer

He au hapa kei te hononga i waenga i te pou whenua me te pito whenua o te energizer, nō reira me whakahaere e ia te putanga katoa o te energizer me te kore e wera, e waikura rānei. E taunaki ana tā mātou tīma hangarau i te 6 mm²(10 AWG) he ara iahiko parahi kua whakamahanatia mō ngā taiapa e whakakahangia ana e ngā mea whakakaha hiko tae atu ki te 10 joule. Mō ngā waeine putanga teitei ake, piki ake ki te 10 mm²(7 AWG) te kaiārahi.

Ka whakaputa mātoungā topenga whenua whakawhiti parahie piri ana i tā mātou ara iahiko ki te tokotoko me te kore e whakapiripiri. Ka ātete te parahi ki te waikura konukōre ina honoa ki te parahi, he huinga kua whakamatautauria e tā mātou tīma kounga i roto i ngā rūma rehu tote. Mā te whakamahi i ngā topenga maitai i runga i te tokotoko parahi ka tere ake te waikura i te hononga, he raruraru e tūpono pinepine ana mātou ina arotakehia ngā tāutanga kore angitu.

Mō te ara hiko mai i te pou whenua ki te energizer, tanumia te taura kia 200 mm te iti rawa i raro i te whenua hei tiaki i a ia mai i ngā waewae kararehe me ngā taputapu pāmu. Ina uru te taura ki roto i te whare, tāutahia he aukati ngaru ki te pūwāhi tomo. Mā tēnei paparanga tiaki ka ārai i ngā whakawhiti ngaohiko kei kino ki ngā ara iahiko o roto o te energizer, ā, ko ā mātou hoa tohatoha e hono ana i ngā aukati me ā rātou kete whenua ka iti ake te ripoata o ngā whakahokinga pūtāhui energizer.

Ngā Rārangi Tiaki me te Tirotiro mō ngā Tūnga Whenua Parahi

Kāore te pou parahi e memeha, e wareware. Ahakoa he pai ake te ātete o te parahi ki te waikura i te maitai, ka rerekē katoa ā mātou pūwāhi hononga, te whakamarumaru hiko, me ngā āhuatanga oneone huri noa i te wā. Ka tūtohu mātou kia whakaakona e ngā kaiwhakarato ā rātou kiritaki ki tētahi tikanga tirotiro ā-tau māmā.

Hipanga 1: Inehia te ātete whenua. Momotuhia te waea whenua mai i te energizer ka whakamahi i te taputapu whakamātautau ātete whenua. Ko ngā pānui whāinga mō ngā taiapa ahuwhenua kei raro iho i te 10 ohms. Mena kua piki ake te ātete ki runga ake i te 25 ohms mai i te tāutanga, tāpirihia he tokotoko, whakapaitia rānei tā tātou whakakī-muri.

Hipanga 2: Tirohia ngā hononga mā te titiro. Tirohia mēnā he waikura matomato kei runga i te ara iahiko parahi (noa) me te paura mā kei runga i ngā hononga konumohe, maitai rānei (he haki whero). Whakakapia ngā taputapu maitai katoa ki te parahi, ki ngā wāhanga kowiri tira rānei. Ā mātouhononga tokotoko whenua parahiā, mā ngā topenga e whakangawari ake tēnei tukanga nā te mea kua hangaia kia pā tika te parahi ki te parahi.

Hipanga 3: Tirohia te kitea o te tokotoko. Ka taea e te horo o te oneone, te mahi rānei a ngā kararehe te whakaatu i te wāhanga o runga o te tokotoko. Mena he nui ake i te 150 mm o te tokotoko kei runga ake i te whenua, whakakīia ki te oneone kua whakakikoruatia, ki te matū kawe hiko rānei hei pupuri i te taumata makuku, ka whakamātauhia e mātou te rohe pa.

Hipanga 4: Tuhia ngā kitenga. Ka whakaratohia e tā mātou wheketere he rārangi tiaki kua tāia mō ia tuku, tae atu ki ngā āpure mō ngā pānui ātete, te āhua o te hononga, me te whakaaturanga o te tokotoko. Ko ngā kaituku e tuku ana i ēnei tuhinga ki ā rātou kiritaki whakamutunga ka whakapakari i te tirohanga ngaio me te whakaiti i te nui o ngā waea tautoko.

Te Whakatutuki i ngā Paerewa Whenua o te Ao

Kei roto i tētahi whenua ture rerekē te mahi a ngā taiapa hiko ahuwhenua i ia whenua, ā, me mārama ō mātou hoa tohatoha ki ngā paerewa e pā ana ki ngā hua e hokona ana e rātou. Ko ngā anga e whai ake nei e whakarato ana i ngā tohutoro ture matua mō ngā hiko whakapūmau i roto i ngā pūnaha taiapa hiko.

UL 467e whakahaere ana i ngā taputapu whenua me te here i Amerika Te Raki. Kei tō mātou wheketere te tiwhikete UL kaha mō ā mātou momo tokotoko whenua parahi, ā, kei roto i ia uta he whakapuakitanga tutuki UL. Me tohe ngā kaituku e kawemai ana ki te Hononga o Amerika, ki Kanata rānei ki ngā tuhinga UL 467 mai i ā rātou kaiwhakarato Haina i te mea ka manatokohia e ngā mana whakahaere tikanga me ngā tari tirotiro ēnei pepa mahi i te wā e tomo mai ai.

Ngā ture haumaru hiko a OSHAe hiahiatia ana kia tutuki i ngā pūnaha whenua i roto i ngā taiao arumoni me ngā taiao ahumahi ngā paepae ātete motuhake. Ahakoa e arotahi ana a OSHA ki te haumaru o te wāhi mahi, kaua ki ngā taiapa ahuwhenua, ka whai hua ngā whare e whakamahi ana i ngā kaimahi e tata ana ki ngā taiapa hiko mai i te whakaatu i te tutuki i ngā whakaritenga a OSHA 1910 Subpart S.

TePaerewa IEC 60335-2-76e kapi ana i ngā pūkaha hiko taiepa me ō rātou pūnaha whenua e pā ana ki te taumata o te ao. I Ūropi, ko tengā whakaritenga pūnaha whenuaKo te mea i whakahuatia i roto i te IEC 62305 mō te tiaki uira ka pā anō hoki ki ngā wāhi e tohaina ana e ngā kaiārahi taiapa te hanganga whenua me ngā tokotoko uira. Ka tohutohu mātou ki ngā hoa tohatoha katoa kia tono pūrongo whakamātautau mai i ngā taiwhanga whai mana e tohutoro ana i ngā rarangi paerewa motuhake e pā ana ki tā rātou mākete ūnga.

Ko tā mātou pūnaha whakahaere kounga ISO 9001 e whakahaere ana i ia wāhanga o te hanga, mai i te rakau parahi e tae mai ana ki te tuhi, te miihini, te tapahi miro, te takai, me te tuku. Ka pupuri mātou i ngā tuhinga whaiwhai e hono ana i ia rakau kua oti ki tōna tau wera rauemi mata, he taumata tuhinga e makona ai ngā kaitātari hoko tino pakari. Mō tētahi kōrero taipitopito atu mō ngā kaha o ā mātou wheketere me te putea tiwhikete, tirohia tā mātouwhārangi whakapāki te tono i te kōtaha o tā mātou kamupene me ngā pūrongo whakamātautau hua.
