He Kupu Whakataki ki te TRD •
Ko te TRD (Trench Cutting Re-mixing Deep wall method), he tikanga hanga pakitara tonu i raro i te oneone sima matotoru ōrite, i whakawhanakehia e Kobe Steel o Hapani i te tau 1993, e whakamahi ana i te pouaka tapahi mekameka kani hei hanga pakitara tonu i raro i te oneone sima matotoru ōrite Hangarau Hanga.
Kua eke te hohonutanga mōrahi o te hanganga i roto i ngā paparanga oneone onepu whānui ki te 56.7m, ā, ko te matotoru o te pakitara he 550mm~850mm. He pai hoki mō ngā momo paparanga rerekē pērā i te kirikiri, te kirikiri, me ngā toka.
He rerekē te TRD i te tikanga hanga pakitara tonu momo-pou o nāianei i raro i te oneone sima i hangaia e ngā mīhini keri porowhita tuaka-kotahi, tuaka-maha rānei tuku iho. Ka whakauru tuatahi a TRD i tētahi taputapu tapahi momo kani mekameka ki roto i te turanga, ka keri ki te hohonutanga kua whakaritea o te pakitara, kātahi ka werohia he matū whakaora, ka whakaranua ki te oneone kei roto tonu, ā, ka haere tonu te keri whakapae me te whakaoho, ka neke whakapae ki te hanga i tētahi pakitara tonu whakaranu sima kounga teitei.
Ngā Āhuatanga o TRD
(1) He nui te hōhonutanga o te hanganga; ka taea e te hōhonutanga mōrahi te eke ki te 60m.
(2) He pai mō ngā momo paparanga whenua maha, ā, he pai te keri i ngā paparanga mārō (oneone mārō, kirikiri onepu, toka ngohengohe, me ētahi atu)
(3) He pai te kounga o te pakitara kua oti, i te taha hohonu o te pakitara, ka taea te whakarite kia ōrite te kounga o te oneone sima, kia kaha ake, kia iti te wehewehe, kia pai ai te pupuri wai.
(4) He tino haumaru, ko te teitei o te taputapu he 10.1m noa iho, he iti te pokapū taumaha, he pai te pumau, he pai mō ngā wāhi he iti te teitei.
(5) He pakitara tonu me ngā hononga iti ake, ā, he rite te matotoru o te pakitara, ka taea te whakatakoto i te maitai āhua-H ki te mokowā tino pai.
Te Mātāpono o te TRD
Ka peia te pouaka tapahi kani mekameka e te motuka waipēhi o te pouaka hiko, ā, ka honoa ngā wāhanga ki te keri ki te hohonu kua whakaritea, ā, ka nekehia te keri whakapae. I taua wā anō, ka werohia te wai totoka ki raro o te pouaka tapahi hei whakaranu kaha me te whakaoho ki te oneone kei roto, ā, ka taea hoki te whakauru i te pakitara whakaranu oneone sima kua hangaia he rite te matotoru ki roto i te maitai kōtaha hei whakanui ake i te pakari me te kaha o te pakitara whakaranu.
Mā tēnei tikanga hanga ka hurihia te tikanga whakaranu o te pakitara whakaranu sima-oneone mai i te whakaranu paparanga whakapae tuku iho o te tokotoko wiri auger tuaka poutū ki te whakaranu whānui poutū o te pouaka tapahi mekameka kani tuaka poutū i te hohonutanga o te pakitara.
