Kei te whakamahia whānuitia te takirere kuwaha mo te tapahi i nga taputapu me te diameter o te DN ≥ 50mm, a, i etahi wa ka whakamahia ano nga raima kuaha mo te tapahi i nga taputapu me nga diameter iti.
Ko te waahanga whakatuwhera me te kati o te keeti kuaha ko te keeti, a ko te ahunga nekehanga o te kuaha e tika ana ki te ahunga o te wai.Ka taea anake te whakatuwhera me te kati i te keti kuaha, kaore e taea te whakatika, te tarai ranei.E rua nga papa hiri o te kuaha.Ko nga papa hiri e rua o te tauira houra kuaha e whakamahia nuitia ana he ahua poro.He rereke te koki poro ki nga tawhā takirere, te nuinga o te 50, me te 2°52' i te mea kaore i te teitei te pāmahana waenga.Ka taea te hanga i te kuaha o te keeti porowhita ki te katoa, e kiia nei ko te keeti maaro;ka taea hoki te hanga hei kuaha ka taea te whakaputa i te iti o te deformation ki te whakapai ake i tona hangahanga me te utu mo te rereke o te koki mata hiri i te wa e tukatuka ana.Ko te pereti e kiia ana ko te kuaha rapa.Ko te paera o te kuwaha te taputapu whakahaere matua mo te rere, te kawe ranei i te nui o te paura, nga mea witi, nga mea kowhatu me nga waahanga iti.Kei te whakamahia nuitia i roto i te whakarewa, te maina, te hanga whare, te witi, te ahumahi matū me etahi atu ahumahi ki te whakahaere i te huringa rere, te tapahi tere ranei.
Ko nga puera o te keeti e tino titiro ana ki nga momo maataki kuaha kuaha, ka taea te wehea ki nga maareti o te keeti, nga paera o te kuaha whakarara, me nga paera o te keeti e ai ki te whirihoranga o te mata hiri.Ka taea te wehewehe i te puera kuwaha ki: momo keeti kotahi, momo kuaha rua me te momo kuaha rapa;Ka taea te wehea te takirere kuwaha whakarara ki te momo kuwaha kotahi me te momo kuwaha rua.E ai ki te tuunga miro o te kakau takirere, ka taea te wehea ki nga momo e rua: te pikinga o te kakau o te kuaha me te kore e piki ake.
I te wa e kati ana te paera o te kuaha, ka taea te hiri te mata hiri anake na te pehanga reo, ara, ma te whakawhirinaki ki te pehanga reo ki te pehi i te mata hiri o te pereti kuaha ki te nohoanga takirere i tera taha ki te whakarite i te hiri o te mata hiri, he hiri-whaiaro.Ko te nuinga o te paera o te kuaha he hiri hiri, ara, ka kati te paera, me pehia te kuaha ki te nohoanga takirere ma te kaha o waho, kia pai ai te hiri o te mata hiri.
Ko te keti o te keti keeti ka neke i roto i te raina tika me te kakau takirere, e kiia nei ko te waapa keeti arai (e kiia ana ko te waapa keeti rising stem).I te nuinga o te waa he miro trapezoidal kei runga i te kaikawe, a na roto i te nati i te tihi o te takirere me te riu kaiarahi i runga i te tinana takirere, ka huri te nekehanga hurihuri ki te nekehanga raina tika, ara, ka huri te taipana whakahaere. ki roto i te mahi aki.
I te wa e whakatuwherahia ana te paera, ka rite te teitei o te pereti kuaha ki te 1: 1 nga wa te diameter o te paera, ka tino wetekina te rerenga o te wai, engari kaore e taea te tirotiro i tenei waahi i te wa e mahi ana.I roto i te tino whakamahinga, ka whakamahia te tihi o te kakau takirere hei tohu, ara, ko te waahi kaore e nekehia te kakau takirere ka tangohia hei tuunga tuwhera katoa.I roto i te tikanga ki te whakaaro i te āhuatanga maukati-ake e tika ana ki te huringa pāmahana, te tikanga tuwhera ki te tūranga runga, a ka tahuri hoki 1/2-1 tahuri, rite te tūnga takirere tino tuwhera.Na reira, ko te tino tuwhera o te waahi ka whakatauhia e te waahi o te kuaha (ara, te whiu).
I roto i etahi maru o te kuaha, ka whakatakotoria te nati kakau ki runga i te pereti kuaha, a, na te hurihanga o te wira o te ringaringa ka peia te kakau takirere kia huri, ka hiki te pereti kuaha.Ko tenei ahua o te takirere e kiia ana ko te kaapu kuaha hurihuri, ko te kaapu kuaha pouri ranei.
