Te Hurihuri Muka Pātara mō te Hanga Hikoi
NGĀ ĀHUATANGA O TE HUA
1. Te ngāwari o te tukanga,
2. He pai ake ngā āhuatanga miihini o ngā hua
3. He ātete pai ki te waikura matū, te ātete waikawa, te ātete kawakore, te ātete tote.
4. Tino ātete ki te kakahu, he pai te whakawhiti maeneene, he pai te muka basalt tonu o te kume,
5. te kaha teitei, te modulus me te ātete ru
6. Ka taea te whakakotahi me ngā momo kapia, he pai te kaha o te here ina whakakotahihia ki te kapia.
7. He pai te ārai hiko
8. He pai te mahi ārai i te hihi ultraviolet.
9. Ātete huka teitei, ātete wera, ātete makuku, Ātete pāmahana teitei tae atu ki te 700℃, ātete pāmahana iti tae atu ki te -270℃.

Ka whakapūmautia te hototahitanga ki ngā momo kapia mā te whakamahi i ngā rahi tika.
Ko ngā hangarau taketake mō te tukatuka i te koiri o te basalt ko ēnei e whai ake nei:
● te pupuhi,
● te takai miro,
● te whatu,
● te hanga papanga maha-tuaka.
Momo:
1. Ko te huri haere tika he miro kotahi-pito tonu kua rite ki te hoko, i hangaia i roto i te tukanga tuhi, ā, i takaihia ki runga i ngā pōpini he 200 mm, 160 mm rānei te whānui o roto. Ko te painga matua o te huri haere tika ko te kore he catenary, ā, he tino pai te āhua.
Koinei te take e whakamahia ai te huri haere tika mō te hanga papanga me ngā geogrids, tae atu ki te hanga kōtaha pultruded me te rebar. Mō ētahi atu tono, me nui ake te kaha o te haere a ngā kiritaki, ki te whakataurite ki te huri haere tika, pērā i te 4800 tex.
Kāore e taea e ētahi kiritaki te whakamahi i te huri haere tika, nā te mea me takai huri haere rātou i runga i ngā pōpini me te puna kaukau o waho. Ka taea te whakaputa i ēnei hua hei huri haere kua huihuia.
2. Ko te mīhini haereere huihui he maha ngā miro kotahi-pito e honoa ana tetahi ki tetahi, kāore e mirohia i runga i te mīhini huihui motuhake.
Ka tukuna ki runga i ngā pōpini he puna kaukau o roto (kāore he ngongo, 76 mm te whānui o roto) me te puna kaukau o waho rānei (ka takaihia ngā pōpini ki runga i tētahi ngongo he 76 mm te whānui o roto, ā, he 270 mm te roa).
NGĀ TONO
E whakamahia ana te keri papatahi i roto i ngā ahumahi rerekē. E whakamahia ana mō te hanga i ngā hua e whai ake nei:
● te rebar mō te whakakaha raima
● ngā kōtaha me ngā paipa
● ngā oko pēhanga teitei
● ngā whatunga whenua
● ngā momo papanga rerekē
