He umanga keri parahi rahi-waenga te kiritaki kei te Rohe o Antofagasta o Chile, ko te nuinga o tā rātou mahi he keri me te tukatuka tuatahi i ngā konganuku parahi. Ko te kaha tukatuka o ia rā o te maina he tata ki te 600 tana. He tawhito ngā taputapu pēhi tātari o nāianei, ā, he raruraru anō hoki pērā i te nui o te makuku i roto i te keke tātari, te iti o te whai huatanga o te tukunga ā-ringa, me te tere o te pakaru o te kakahu tātari. Ko te tumanako a te kiritaki ki te whakauru i tētahi pūnaha wehewehe totoka-wai aunoa katoa hei whakaiti i te utu kawe i ngā paru me te whakapai ake i te tere whakamahinga o te wai whakahoki.
Otinga
I whakaratohia e mātou ki tēnei kiritaki hemīhini tātari momo pouaka aunoa katoa(Tauira 1000, anga maitai waro, putanga wai huna). Kei roto ko te pēhi waipēhi aunoa, te pupuhi kōhao aunoa, te kume pereti aunoa, me te tuku wiri aunoa. He mea hanga ngā pereti tātari ki te rauemi PP ātete-waikura. I whirihorahia te rohe tātari kia rite ki ngā hiahia o te kiritaki. Kua whakatakotoria te pēhanga tātari ki te 0.6 MPa, kia mau ai te whakahaere i te matotoru o te keke tātari ki te 30 mm. Ka whakamahia e te atanga mīhini he flange HG me te DN80 kawemai, e hono pai ana ki ngā paipa o nāianei a te kiritaki.
Pānga Mahi
-
Kua heke te nui o te makuku o te keke tātari mai i te 28% taketake ki raro iho i te 22%, ā, kua tino whakaitihia te taumaha kawe.
-
Ka whakaitihia te wā tukunga e te pūnaha wiri aunoa mā te 8 meneti mō ia huringa, ā, ka whakaitihia te hiahia mō te wawaotanga ā-ringa mā te 70%.
-
Ka āraihia te turuturu o te paru, ka karohia te tauhiuhi, ā, ka whakapai ake i te taiao mahi o te awheawhe.
-
Mā te matotoru pumau o te keke tātari 30 mm ka māmā ake te whakarārangi me te kawe i muri mai.
-
He iti iho te nui o ngā matū totoka i whakatārewatia i roto i te wai whakahoki mai i te paerewa e tumanakohia ana e te kiritaki, e āhei ai te whakamahi anō i roto i te tukanga whakaputa.
Urupare a te Kaihoko
I kī te kaiwhakahaere whakaputa o te maina:"He tino aunoa te mahi a tēnei mīhini tātari. Mai i te pēhitanga ki te tukunga, kāore he take mō te wawaotanga ā-ringa. He tino whai hua ngā mahi pupuhi kōhao me te wiri. He tino maroke te keke tātari, ā, he tino ma te tukunga. Kei te whakamahere mātou ki te hoko i tētahi atu i te tau e tū mai nei mō tētahi atu raina whakaputa."
Whakarāpopototanga Take
I angitu te whakatika a tēnei maina parahi o Chile i ngā take o te iti o te whai huatanga o te tango wai i ngā paru me ngā utu mahi nui mā te whakauru i te mīhini tātari momo-pouaka aunoa, kia taea ai te whakaiti i ngā para me te whakaora i ngā rauemi wai. E tika ana hoki tēnei otinga mō ngā whakaritenga wehenga totoka-wai i roto i ētahi atu ahumahi keri, matū, me te tiaki taiao.
