Ko te pou o te punga i muri i te reaming te tikanga i muri i te werohanga o te kohao tika i roto i te papa raima, ka rea ano te kohao ki raro o te poka, a ko te kohao i muri i te reaming me te waahanga matua tuwhera o te punga o te punga ka hanga he tikanga hono ki te mohio ki te hononga pou-punga.
Ko te raka punga miihini o muri kei te tito, te papa o raro, te horoi papatahi, te horoi o te puna, te nati, he mea hanga ki te 5.8 karaehe rino, 8.8 karaehe rino, 304 (A2-70)/316 (A4-80) he kowiri tira me etahi atu mea. Ko te maimoatanga mata he electrogalvanizing (te matotoru o te paparanga konutea toharite ＞ 5 μm), ka whakamahia ki te taiao noa; Hot galvanizing (toharite matotoru paparanga zinc>45 μm), whakamahia i roto i te taiao ha'iriiri.
Ka whakamahia te rea rear belled mechanical punga punga i runga i nga rauemi turanga penei i te raima kore-ngatata / raima pakaru, te kohatu taiao, me etahi atu, hei whakatika i nga waahanga hanganga me te kawenga nui, te whakauru ranei i nga taputapu taimaha. Ko te raka punga miihini roha o muri he pumau, he pai hoki te mahi punga i raro i te kawenga teitei, te wiri me te kawenga awe. Whai muri i te maukati miihini me te whakaurunga ki te waahi, kaore he take me tatari mo te wa rongoa hei whakapai ake i te mahi hanga.
Ko te mahi o te raka punga miihini mo te roha o muri o raro ko enei e whai ake nei: tuatahi, whakamahia he kohao poka tika ki te keri rua me te hohonutanga o nga diameters e rite ana, katahi ka whakamahi i te kohao roha motuhake o raro ki te wiri i raro ki te whakawhänui i te raro ki roto ki nga kohao porowhita, katahi ka whakamahi i te pupuhi hiu ki te whakatika i te kohao kia kore ra ano e rere te puehu i roto i te kohao ki raro, katahi ka pa atu te rea ki raro.
