Paipa Ārai, he momo hangarau e whakamahia whānuitia ana i te āhua o ngā hononga paipa rite ki te ngaru, te maitai waro, te maitai kore waikura, te konukōre, te konumohe, me ētahi atu hei rauemi mata matua. Ka taea te whakamahi i roto i te matū hinu, te taputapu, te rererangi, te matū, te hiko, te sima me ētahi atu huarahi.
Ngā momopaipa kōpikopiko
Ko ngā pupuhi hau ko ngā pupuhi hau whakarewa, ngā hononga whānui kōpikopiko, ngā ngongo whakawhiti wera kōpikopiko, ngā pouaka pupuhi hau kōpikopiko me ngā ngongo whakarewa.
Ko te nuinga o te wā, ka whakamahia te pupuhi whakarewa hei whakakapi i te rerekētanga wera o ngā paipa, te mimiti ru, te mimiti i te rerekētanga taunga o ngā paipa, me ētahi atu. He whānuitia te whakamahinga i roto i te matū hinu, te taputapu, te rererangi, te matū, te hiko, te sima, te whakarewa me ētahi atu ahumahi.
He mea nui te kirihou me ētahi atu rauemi pēnei i ngā paipa kōpikopiko ki te kawe i ngā mea, te miro hiko, ngā taputapu mīhini, ngā taputapu kāinga me ētahi atu mara.
Ngā painga o ngā pūwero whakarewa
Painga 1: He iti ake te utu o te kaupapa piriti whakarewa i te whānuitanga kotahi o te raima whakapakari, inā koa i roto i te mara hangahanga motuhake o te whenua he nui ake te utu-whai hua.
Painga 2: he hoahoa hiri rua ngā mea whakarewa, he pai te tiaki i te tukanga hanga o te whakakī i te paipa kia kore ai e turuturu te whakakī.
Painga 3: roa te ora mahi, iti ake te tiaki, inā koa te ātete ki te waikura o ngā mea whakarewa piauau, kāore e hiahiatia he hononga whānui me ngā peera me ētahi atu wāhanga kakahu i roto i ētahi hanganga piriti.
Painga 4: he māmā ake ōna āhuatanga, i roto i te mahi whakarite me te kawe waka me te honohono hangarau i runga i te papaanga, kāore e hiahiatia he taputapu miihini nui hei āwhina, ko te honohono ā-ringa anake ka taea te mahi ā-ringa, he tere rawa te tāutanga me te hanga.
Ngā āhuatanga e pā ana ki te utu o te paipa whakarewa kōpikopiko
1, he rite te rahi o te pūwero whakarewa ki te rahi, te rahi, te rahi me te diameter, ko te nui ake te utu.
2, he rerekē hoki te utu o te hanga o ngā paipa pupuhi whakarewa i hangaia mai i ngā rauemi whakarewa rerekē.
3, ka pāngia hoki te utu e te roa o te hoko rarawe o ngā pupuhi whakarewa, nā te mea ka roa ake te hoko, ka iti ake te utu toharite mō ia mita o ngā pupuhi whakarewa e tukuna ana e ngā kaihanga.
4, he nui ake te utu mō ngā pupuhi whakarewa me te kore he pupuhi whakarewa, he rite tonu ngā whakaritenga ki ngā pupuhi whakarewa prestressing.
Ko te whakamahinga matua o ngā pūwero whakarewa
1.Paipa Rino Āwhiowhioe whakamahia ana mō te whiti i te rori, i te ara rerewē rānei, te ara waikeri, te urunga mō te hunga hīkoi me te waka, me ngā puna wai turuturu.
2. Whakamahia i roto i ngā momo paipa waikeri hangarau ā-iwi katoa, te waikeri me te rohe noho me ētahi atu whanaketanga whenua me te paipa waikeri, te papa korowha, te paipa.
3. Ko te paipa rino kōpikopiko te nuinga e whakamahia ana i roto i te paipa rerenga wai roa o te rerewē, te paipa rerenga wai o te wheketere, te paipa wai whakamakuku ahuwhenua, te tuku wai me te tuku. Ka taea hoki te whakamahi i ngā taura whakawhitiwhiti huarahi, te taura whakawhitiwhiti whenua o te rerewē, te hau me ētahi atu raina i waho o te paipa tiaki, mō ngā mahi hanga o nāianei.
Ka taea hoki te whakamahi i roto i te mara hanga, i te whare tiaki, me ētahi atu.
4. Whakamahia i roto i ngā pakitara pupuri pepa kowakawaka maitai, ngā puranga pepa kowhara me ērā atu.
5, he rerekē te waitohu o ngā kaihanga o ngā pūwero whakarewa, he rerekē hoki te tuku a ngā kaihanga waitohu rerekē.
