Me noho he hongere i waenga i te whakaputunga o nga taputapu putorino paiherea. Ko te whanui o te hongere tirotiro he 0.5m te nuinga. Ko te whanui o te hongere whangai ka whakawhirinaki ki te rahi o nga rawa me nga miihini kawe, te tikanga 1.5 ~ 2m. Ko te teitei o nga putorino maitai torino kaua e neke ake i te 1.2m mo te mahi a-ringa, 1.5m mo te mahi miihini me te 2.5m mo te whanui o te taapu. Hei tauira, mo nga putorino maitai kua taia ki te hau, me whakanoho he kowhatu tarai, kowhatu tihorea ranei ki raro i te putorino maitai torino, me te anga o te mata o te paparanga kia pai ai te rere o te wai.

Mena kei te rongoa i te waahi tuwhera, ko te teitei o te papa ciment kia 0.3 ~ 0.5m, me te teitei o te papa onepu i waenga i te 0.5 ~ 0.7m. Ko te kaha o te putorino paiherea torino he nui ake i tera o te putorino whiri tika, a ka taea te whakamahi i tetahi putunga whaiti hei hanga i tetahi putorino paiherea te diameter nui, a ka taea te whakamahi i tetahi putunga o te whanui rite tonu hei whakaputa i tetahi putorino paiherea. rerekē diameter paipa. Heoi, ka whakaritea ki te putorino tui tika o te roa rite, te roa o te fehokotaki'anga kua piki ake e 40 ~ 100%, a he iti te tere production.
