Hangarau Tunneling Haumaru i te Papa Heterogene
Te ahua o te whenua:
He oneone ngawari, he rereke nga hanganga (he onepu, kirikiri, teitei te uruhanga me te pehanga wai nui)
Ko te NPD raupapa putorino Jacking mīhini he te nuinga e tika ana mo nga tikanga matawhenua ki te pehanga wai whenua tiketike, me te whakarea uruhanga oneone tiketike. Ko te parae kua keria ka peehia mai i te kauhanga i roto i te ahua o te paru na roto i te papu paru, na reira he ahuatanga o te tino pai o te mahi me te taiao mahi ma.
E ai ki nga huarahi rereke o te whakahaere i te paru i runga i te mata keri, ka taea te wehea te miihini miihini putorino raupapa NPD ki nga momo e rua: te momo whakahaere tika me te momo whakahaere autaki (te momo mana hiato hau pehanga).
a. Ka taea e te momo mana whakahaere tika te miihini miihini paipa paipa te whakahaere i te pehanga mahi o te tank wai paru ma te whakatika i te tere o te papu paru, te whakatika ranei i te whakatuwheratanga o te putunga mana wai paru. He ngawari, he watea hoki tenei tikanga whakahaere, a he iti te reeti kore.
b. Ko te miihini miihini putorino whakahaere autaki ka whakatika i te pehanga mahi o te tank wai paru ma te huri i te pehanga o te tank urunga hau. Ko tenei tikanga whakahaere he urupare tairongo me te tika o te mana whakahaere.
1. Ka taea e te urunga hau whakahaere aunoa te tautoko tika mo te mata o te kauhanga, kia pai ai te haumaru o te taraiwa taraiwa ki te tino nui.
2. Ka taea hoki te whakahaere i te kohanga ina ko te pehanga wai kei runga ake i te 15bar.
3. Whakamahia te paru hei reo matua ki te whakataurite i te pehanga hanga i runga i te mata keri o te kauhanga, me te tuku i te para ma te punaha kawe paru.
4. NPD raupapa putorino Jacking mīhini he pai mo te hanga kauhanga ki te pēhanga wai teitei me ngā whakaritenga whakataunga whenua tiketike.
5. Te kaha o te taraiwa, te haumaru me te pono, me nga tikanga toenga e rua o te whakahaere tika me te whakahaere kore.
6. Ko te NPD raupapa putorino Jacking mīhini ki matatau me te pono hoahoa upoko cutter me te tohanga paru.
7. Ko te NPD raupapa putorino Jacking mīhini tango i te kawe matua pono, hiri puku matua me te whakaiti puku matua, ki te ora ratonga roa me te take haumaru tiketike.
8. Pūnaha rorohiko whakahaere whaiaro-whakawhanakehia, he haumaru, he pono hoki te mahi o te miihini katoa, a he watea te mahi.
9. Te whanui o nga momo oneone e tika ana, penei i te oneone ngohengohe, te uku, te onepu, te kirikiri oneone, te oneone maro, te whakakii, me era atu.
10. Te wero wai motuhake, te punaha tuku.
11. Ko te tere tere tata ki te 200mm ia meneti.
12. Ko te hanga o te tino tika, te urungi pea ko runga, whakararo, maui me matau, me te koki urungi o te 5.5 nga nekehanga.
13. Whakamahia te punaha whakahaere pokapū i runga i te whenua, he haumaru, he maamaa, he waatea hoki.
14. Ka taea te whakarato i te raupapa o nga otinga kua hangaia mo nga whakaritenga kaupapa rereke.
