Painga Kamupene

Kei waenganui o te Tāone o Cangzhou, Porowini o Hebei, ko te kamupene te kaiārahi i roto i te hanga paipa whakarewa mai i tōna whakatūnga i te tau 1993. E 350,000 mita pūrua te rahi o te tipu, ā, he mīhini me te hangarau matatau kei roto hei whakaputa hua tino pai e tutuki ana i ngā paerewa o te ao. Me ngā rawa katoa o te RMB 680 miriona me ngā kaimahi mohio 680, e whakapau kaha ana te kamupene ki te hiranga i roto i ngā āhuatanga katoa o āna mahi.

Whakataki Hua

Kei te whakauru atu mātou i tā mātou hangarau whakarewa paipa tino matatau, i hangaia kia tutuki ai ngā whakaritenga uaua o ngā paipa hau māori whakarewa āwhata. Kei mua i tēnei auahatanga ko tā mātou hangarau whakarewa āwhata ruku (SAW) matatau, te tikanga pai mō ngā paipa whakarewa porowhita. Mā tēnei hangarau ka whakarite kia tika, kia roa, kia whai hua hoki, ā, he mea tino pai mō ngā ahumahi e whakawhirinaki ana ki ngā paipa whakarewa kounga teitei.

Ā mātou tohungatangawhakarewa paipaEhara i te mea ka whakapai ake te hangarau i te hanganga o ngā paipa hau anake, engari ka arotau hoki i te tukanga whakarewa, ka whakapoto i te wā whakaputa me te whakaiti i ngā utu. E mārama ana mātou ki te hiranga o ngā pūnaha paipa hau, ā, mā tā mātou whakapau kaha ki te kounga ka taea e ā mātou hua te tu atu ki ngā tono pakari o ā rātou tono.

I a mātou e whakahou tonu ana, e whakapai ake ana hoki i te hangarau whakarewa, ka tono atu mātou kia wheako koe i te pono me te mahi a tā mātou hangarau whakarewa paipa ngaio. Whakawhirinaki mai ki a mātou ki te whakarato i te paipa whakarewa kounga teitei e tutuki ai ō hiahia, me te tautoko i ngā tekau tau o te tohungatanga me te whakapau kaha ki te makona o ngā kiritaki.

Painga Hua

1. Ko tētahi o ngā painga matua o te whakamahi i te whakarewa pewa ruku ki te whakarewa i ngā paipa hau maori ko tōna kaha ki te whakaputa i te kounga teiteiwhakarewa ngongome te iti o ngā hapa. Mā te tukanga whakarewa pewa i raro i te wai ka taea te uru hohonu me te maeneene o ngā mata, he mea nui ēnei hei whakarite i te pumau o ngā paipa hau māori.

2. Mā te aunoatanga o te whakarewa pewa i raro i te wai ka taea te whakanui ake i te hua me te whakaiti i ngā utu mahi me te wā mahi.

Ngā ngoikoretanga o te hua

1. Ko tētahi ngoikoretanga nui ko te nui ake o ngā utu whakatūnga tuatahi, ka nui pea nā te hiahia mō ngā taputapu motuhake me ngā kaiwhakahaere mohio.

2. Kāore te tukanga i te tino ngāwari pērā i ētahi atu tikanga whakarewa, ā, kāore i te tino pai mō ngā āhuahanga uaua, ngā rauemi angiangi rānei.

3. Ka taea e tēnei herenga te whakararu i ētahi tono, ā, ka roa ake pea ngā wātaka kaupapa.

P2. He aha i pai ake ai te SAW mō ngā paipa whakarewa porowhita?

Mā te hangarau SAW ka hohonu te urunga me te mata maeneene, he mea nui tēnei mō te hanganga o tepaipa porowhita kua whakarewainae whakamahia ana i roto i ngā mahi pēhanga teitei pērā i te kawe hau māori.

P3. He aha ngā painga o te whakamahi i te hangarau whakarewa paipa ngaio?

Mā ngā tikanga whakarewa ngongo motuhake ka whakarite i te kounga pumau, ka whakaiti i te mōrearea o ngā hapa, ka whakapai ake hoki i te mahi whānui o ngā hua whakarewa, he mea nui tēnei i roto i tētahi ahumahi e tino hiahiatia ana te haumaru.

P4. Me pēhea te whakarite a tō kamupene i te kounga o te tukanga whakarewa?

E piri ana tā mātou kamupene ki ngā tikanga whakahaere kounga tino pakari, ā, e whakamahi ana i ngā tohunga hangarau mohio kua whakangungua ki ngā tikanga whakarewa hou, tae atu ki te SAW, kia tutuki ai i ia hua ngā paerewa haumaru me te mahi tino pakari.
