te rerekētanga i waenga i te keri poutū, te puranga hurihuri me te HDD trenchless

Whakamāramatanga: He tikanga keri tuku iho e hanga ana i ngā kōhao poutū ki te mata o te Ao hei uru atu ki ngā rauemi o raro i te whenua, hei hanga rānei i ngā hanganga poutū.

Mātāpono Mahi: Ka panaia te mata keri hurihuri (hei tauira, te mata tricone, te mata PDC) ki raro mā te kaha miihini, te kaha waipēhi rānei. Ka hurihia te wai keri (paru) hei whakamatao i te mata, hei tango i ngā tapahi, hei whakau i ngā pakitara o te poka.

Ngā tono matua:

• Te tango hinu, te hau māori, ngā kohuke rānei (hei tauira, te waro, ngā konganuku).

• Te keri i ngā puna wai, ngā puna waiariki, ngā puna aroturuki rānei mō ngā rangahau taiao.

Ngā Painga: Te kaha ki te hohonu (tae atu ki ngā mano mita), te tūnga poutū tika, me te pai mō ngā hanganga toka mārō.

Ngā Here: Me nui te wāhi e hiahiatia ana, ka whakararuraru i te oneone mata, ā, kāore e taea te whakatere i ngā arai whakapae (hei tauira, ngā awa, ngā rori).

2. Te Whakatō Pouaka Hurihuri

Whakamāramatanga: He tikanga hanga turanga motuhake e keri ana i ngā poka pūmau, paku piko rānei hei tāuta i ngā pou raima, maitai, puranga hiato rānei (ngā hanganga pikaunga mō ngā whare/piriti).

Mātāpono Mahi: Ka whakamahia e te mīhini keri hurihuri he peere keri tuwhera, he auger rānei hei keri i te oneone/toka. I muri i te hanganga o te poka, ka whakauruhia ngā kēti whakapakari, ā, ka ringihia te raima (i raro i te pēhanga i te nuinga o te wā) hei hanga i tētahi puranga.

Ngā tono matua:

• Ngā turanga hanga mō ngā whare teitei, ngā piriti, ngā tauranga, ngā whare ahumahi rānei (hei tohatoha i ngā kawenga hanganga ki ngā paparanga o raro i te whenua pumau).

• Te whakau i ngā pari, te whakatika rānei i ngā turanga o nāianei.

Ngā Painga: He tere te hanga puranga, he urutau ki ngā momo oneone rerekē (te uku, te onepu, te toka ngohengohe), ā, he iti ake te wiri i te whakataurite ki te puranga hama.

Ngā Here: Me whakarite te mata papatahi, ka pakaru pea te poka wai i ngā oneone koretake (me whai anga), ā, ka herea ki ngā hohonutanga papaku ki te āhua noa (te nuinga o te wā <100 mita).

3. Kore-Waihanga HDD (Keri Aronga Whakapae)​

Whakamāramatanga: He tikanga auaha "kāore e keri" e keri ana i ngā poka whakapae, i ngā poka ahunga rānei i raro i te mata o te whenua hei tāuta i ngā ratonga o raro whenua (ngā paipa, ngā taura) me te kore e keri i ngā awaawa.

Te Kaupapa Mahi:

1. Ka keria he "pōhatu whakamātau" iti i te ara whakapae kua hoahoatia i mua mā te whakamahi i te pane keri ka taea te urungi (mā te GPS, mā te gyroscope rānei e ārahi).

2. Ka whakanuia (ka whakatikatikaina) te kōhao pairati kia ōrite ki te whānui o te taputapu.

3. Ka hutia te paipa/taura ratonga i roto i te poka wai kua whakanuia.

Ngā tono matua:

• Te tāuta i ngā paipa wai/parakaingaki, ngā raina hau, ngā taura muka whatu rānei i raro i ngā rori, ngā rēriwe, ngā awa, ngā taunga rererangi, ngā wāhi tairongo taiao rānei (hei tauira, ngā repo).

Ngā Painga: He iti noa te whakararuraru i te mata (kāore he keri awaawa), he tiaki i te rere o ngā hanganga/waka, ā, he whakaiti i te pānga ki te taiao.

Ngā Here: He iti ake te kaha o te hōhonutanga (te tikanga <100 mita), he iti noa iho ki ngā oneone ngohengohe ki te reo (ka piki ake te utu o te toka mārō), ā, me tika te whakatere (mōrearea te peka o te ara keri).
