Tirohanga Whānui o te Makahanga Takirere

1. He aha te mahi maka

Ka ringihia te whakarewa wai ki roto i te kōhao pokepokea ai he āhua e tika ana mō te wāhanga, ā, i muri i tōna whakapakeketanga, ka puta he hua wāhanga he āhua, he rahi, he kounga mata anō hoki, e kiia nei ko te whakarewanga. E toru ngā huānga matua: te koranu, te whakatauira, te ringihanga me te whakapakeketanga. Ko te painga nui: ka taea te hanga i ngā wāhanga uaua.

2. Te whakawhanaketanga o te whakarewanga

I tīmata te hanga i te tekau tau atu i 1930 mā te whakamahi i ngā mīhini hau me ngā tukanga onepu uku horihori.

I puta mai te momo onepu sima i te tau 1933

I te tau 1944, ka puta te momo anga onepū kapia pania mārō matao

I puta mai te pokepokea ai te karāhe wai CO2 whakapakeke i te tau 1947

I te tau 1955, ka puta te momo anga onepu paninga wera

I te tau 1958, ka puta mai te pokepoke onepu kore-tunu kapia furan.

I te tau 1967, ka puta te pokepoke onepu rere sima

I te tau 1968, i puta mai te karāhe wai me te whakapakeke waro

I roto i ngā tau 50 kua pahure ake nei, kua puta mai ngā tikanga hou mō te hanga pokepokea ai mā te whakamahi i ngā tikanga ā-tinana, pērā i te: pokepokea ai he pere aukume, te tikanga pokepokea ai he hiri korehau, te pokepokea ai he pahuka ngaro, me ētahi atu. He maha ngā tikanga pokepokea ai e ahu mai ana i ngā pokepokea ai he konganuku. Pērā i te pokepokea ai he porowhita, te pokepokea ai he pēhanga teitei, te pokepokea ai he pēhanga iti, te whakaputa wai, me ētahi atu.

3. Ngā āhuatanga o te maka

A. He whānui te urutau me te ngāwari. Ngā hua rauemi whakarewa katoa. Kāore te whakarewa e herea e te taumaha, te rahi me te āhua o te wāhanga. Ka taea te taumaha mai i te torutoru karamu ki te rau tāne, ko te matotoru o te pakitara mai i te 0.3mm ki te 1m, ā, ka taea te hanga i ngā wāhanga tino uaua.

B. Ko te nuinga o ngā rauemi mata me ngā rauemi āwhina e whakamahia ana he whānuitia te pūtake, ā, he iti te utu, pērā i te rino para me te onepu.

C. Mā te hangarau whakarewa matatau ka taea e ngā whakarewanga te whakapai ake i te tika o ngā āhuatanga me te kounga o te mata o ngā whakarewanga, kia iti ake ai te tapahi i ngā wāhanga, me te kore e tapahia.
