Te Tiaki i ngā Hanganga Tiaki me ngā Whare Tautoko i ngā Whare Hiko Wai
He hanganga nui ngā tipu hiko wai (PLTA) e whakawhirinaki ana ki te pono o ngā pūnaha waipēhi, mīhini, me te pūnaha ā-iwi i te wā kotahi. Kei muri i te whakahaere o ngā tāpine me ngā whakaputa hiko, kei reira ngā wāhanga nui, e warewarehia ana: ko ngā hanganga tiaki me ngā hanganga tautoko. He mahi nui tā rāua ki te pupuri i te haumaru mahi, te tiaki i ngā taputapu matua, me te whakarite i te pumau o te puna hiko. Nā te mea e mahi ana i roto i ngā taiao maku, pēhanga, ā, he ngāwari ki te para me te waikura, me whai kaupapa tiaki kua whakaritea, kua tuhia, me te haere tonu ngā hanganga tiaki me ngā hanganga tautoko.
Te Mārama ki ngā Hanganga Tiaki me ngā Whare Tautoko
Kei roto i ngā hanganga tiaki i ngā tipu hiko wai ngā huānga i hangaia hei tiaki i ngā taputapu, ngā kaimahi, me ngā hanganga mai i ngā pānga o te wai, ngā mea e mānu ana, te pēhanga waipēhi, me ngā pakaru pea o te pūnaha. Hei tauira, ko ngā whata para, ngā kēti whakauru, ngā poro rākau aukati, ngā kēti putanga wai, ngā taiepa pupuri, te tiaki pareparenga, me ngā pūnaha waikeri me te whakamaroke wai. Ka taea hoki e ngā hanganga tiaki te whakauru i ngā pareparenga, ngā ārai waipuke, me te tiaki horo i ngā wāhi tino nui.
I tēnei wā, ko ngā whare tautoko he whare e tautoko ana i ngā mahi me ngā mahi tiaki, pērā i ngā rori urunga, ngā piriti tirotiro, ngā whare whakahaere, ngā whare takirere, ngā awheawhe, ngā whare putunga, ngā whare kerēni/whakapūmau, ngā pūnaha rama, me ngā awa waikeri o te rohe. Ko te pono o ngā whare tautoko e whakatau ana i te maeneene o te whakahaere o ngā tirotiro, te urupare ohorere, me te nekenekehanga o ngā taputapu taumaha.
He aha te mea nui o te tiaki i ngā tipu hiko wai?
He wero motuhake kei roto i te taiao mahi o ngā tipu hiko wai. Ka haria e te rere o te wai te paru, te onepu, ngā toka, me ngā para rauropi. Ka pāngia te kawenga waipēhi i runga i te putanga me te ara ringihia e ngā huringa o te wā. Hei tāpiri, ka ngawari te waikura o ngā hanganga whakarewa nā te nui o te haumākū; ka pakaru pea ngā hanganga raima nā te huringa makuku-maroke, ngā tauhohenga matū, ngā pānga rānei o te mimiti paru. Ki te kore e āta mahia te tiaki, ehara i te mea ko te whakaiti i te pai o te whakaputanga anake te pānga engari ko te mōrearea o ngā whakararuraru mahi, ngā kino nui, tae atu ki ngā aituā haumaru.
Ngā Wāhanga Tiaki i runga i te Whatanga Para me te Pūtake Para
Ko te mahi a te whata para he tātari i te para kia kore ai e uru ki te paipa whakauru me te kino ki te tāpine. Ko te tiaki auau ko te horoi ā-ringa i te para, te whakamahi rānei i te kaihoroi whata para, te tirotiro i ngā tokotoko mō te rerekētanga, te whakakī i ngā pūtu, te whakapiri anō rānei i ngā wāhi ngoikore, me te tirotiro mō te waikura. Ko tētahi tohu noa o ngā raruraru whata para ko te pikinga o te ngaronga o te pane (te hekenga o te pēhanga), ka taea te whakaiti i te rere o te haunga whakauru o te tāpine me te akiaki i te waeine kia mahi i ngā āhuatanga kāore i te tino pai.
Me aro nui ki ngā ara ārahi, ki ngā hiri rapa, ki te pūnaha whakaoho, me ngā mata pa ki ngā kēti whakauru me ngā rākau aukati. Ka taea e ngā hiri kua pakaru te turuturu, te whakanui ake i te ngaronga pūngao, me te whakararu i te wehenga i te wā whakatikatika. He mea nui te whakamātautau mahi ā-wā o ngā takirere whakatuwhera-kati kia tere ai te urupare mēnā ka puta he āhuatanga ohorere.
Te Tiaki i ngā Ara Waipuke me ngā Pūnaha Whakaora Waipuke
Ko ngā awaawa me ngā awaawa ngā hanganga tiaki matua mō te waipuke. Ka mate pea ēnei taputapu mēnā ka kore e taea. Ko ngā kaupapa tiaki ko te tirotiro ā-kanohi i ngā mata raima (te ngatata, te pakaru, te horo), te horoi, me te arotake i te āhua o ngā pou, ngā āpere, me ngā peihana whakamārie. Ka taea e te paru me ngā toka e pā ana ki te mata o te awaawa te whakararu; nō reira, he mea nui te whakatika i ngā paninga tiaki (hei tauira, ngā moata motuhake, ngā epoxies rānei).
Mai i te tirohanga ā-mīhini, me tirotirohia te pūnaha hiki, te taura waea, te pūrei, me te waipēhi mō te whakahinuhinu, te pakaru, me te whakatikatika. Me whakamātautau te pūnaha whakahaere me ngā pūoko taumata wai kia tika ai te mahi a te kēti turuturu. Mā ngā whakamātautau mahi ā-wā ka āwhina kia kore ai ngā kēti e piri i muri i te kore mahi mō te wā roa.
Te Tiaki i te Horo, Ngā Pari, me te Hanganga Oneone
He maha ngā wā ka tū ngā tipu hiko wai i ngā wāhi maunga, i ngā awaawa rānei, he nui te mōrearea o te horo whenua me te horo. Ko te tiaki i ngā hanganga pari parepare pērā i te riprap, te gabions, te taiepa pupuri, me ngā awaawa whakawhiti rere me aro ki te pumau o te pari, me te ārai i te whakahoro (te horo o ngā turanga e te rere). He mea nui ngā tirotiro i muri i te ua nui, i te waipuke rānei, nā te mea ka taea e ngā huringa tere o te āhua o te whenua te whakararu i te urunga ki te rori me te haumaru o te whare.
He mea nui te waikeri i te rohe. Ka taea e ngā waikeri kua purua te whakatō, te whakateretere i te pirau o ngā ara, me te whakanui ake i te makuku i roto i ngā turanga whare. Ko te horoi i ngā waikeri, te whakatika i ngā pari, me te whakahaere i ngā otaota he mahi noa iho e ahua māmā ana engari he nui te pānga.
Te Tiaki i ngā Whare Whakahaere, ngā Awheawhe, me ngā Whare Tautoko
Me tiaki ngā whare whakahaere me ngā rūma panui i ngā mahi hangarau ā-iwi (tuanui, pakitara, papa) me ngā whakahaere taiao (haumākū, hauhautanga, me te ma). Me whakatika wawe ngā turuturu o te tuanui me te turuturu o te pakitara nā te mea ka kino pea ngā taputapu hiko me ngā taputapu. I roto i ngā awheawhe me ngā whare putunga, me arotake auau ngā āhuatanga haumaru pēnei i te āhua o te papa (ārai-paheke), te rama, te hauhautanga, me te whakatakotoranga o ngā rauemi.
He mea nui ngā kerēni, ngā hiki, me ngā ara monorail mō te tiaki i ngā wae whakaputa hiko. Me whakahaere ngā tirotiro kawenga, te tiwhikete taputapu hiki, te whakamātautau pana rohe, me ngā tirotiro hanganga tautoko i runga anō i ngā paerewa haumaru mahi. Ehara i te mea ka whakaroa noa i ngā whakatikatika te rahunga o ngā taputapu hiki, engari ka taea hoki te whakararu i ngā aituā.
Ngā Tikanga Tirotiro me ngā Tikanga Tiaki
Ko ngā tirotirohanga o ngā tipu hiko wai he mea tino pai ki te whakakotahi i ngā tikanga tirohanga, ngā inenga, me ngā whakamātautau kore-whakangaro. Mō te raima, ka taea te whakamahi i te mahere pakaru, ngā whakamātautau hama, me te whakamātautau whakahoki. Mō ngā hanganga whakarewa, ka āwhina te ine matotoru ultrasonic ki te aroturuki i te waikura. I ngā wāhi i raro i te wai, ka taea te whakahaere tirotiro mā te ruku, mā ngā waka e whakahaeretia ana e te tawhiti (ROV), inā koa mō te putanga wai, ngā pakitara awa, me ngā turanga.
Ko ngā mahi tiaki ārai ko te horoi, te whakahinuhinu, te peita ārai-waikura, te whakakapi hiri, me te whakakaha i ngā hononga. Ko ngā mahi tiaki whakatikatika ko te whakatika i ngā kapiti raima (werohanga epoxy), te tākai i ngā paparanga, te whakakapi i ngā wāhanga kua tawhito o te kēti/hī, me te whakaora anō i ngā mata o te ara wai kua pakaru. I ētahi wā, me tiaki matapae e hangai ana ki te āhua, hei tauira mā te aroturuki i te wiri hī, ngā ia turuturu o te kēti, te whakanui ake rānei i te ngaronga o te upoko i te tomokanga.
Te Whakahaere Para me te Para
He hoariri nui te oneone i ngā tipu hiko wai nā te mea ka taea e ia te whakaiti i te kaha o te puna wai, me te whakanui ake i te pakū o ngā tāwhana. Ko ngā hanganga tautoko pēnei i ngā peihana taunga, ngā mahanga onepu, ngā kēti horoi, me ngā pūnaha horoi me tiaki nui kia mau tonu ai te mahi. Mā te whakahaere para i runga i te awa mā roto i ngā pūngao, ngā ārai para, ngā pūnaha horoi aunoa rānei ka taea hoki te whakaiti i te taumahatanga tiaki i runga i ngā whata para. Me whakauru te whakahaere oneone ki ngā tauira whakahaere puna wai, ā, me whakarite ki te whakahaere i ngā awaawa.
Haumaru Mahi me te Tuhituhi
Ko te tiaki i ngā wāhi e rere ana te wai, e teitei ana, e taumaha ana ngā taputapu me whakatinana kia tino tika te haumaru me te hauora mahi (K3). He mea whakahau ngā tikanga raka-tohu-kore, ngā tikanga whakaaetanga-ki-te-mahi, te whakamahi i ngā taputapu tiaki whaiaro (PPE), te haumarutanga o te wāhi mahi, me ngā mahere whakawātea. Hei tāpiri, ko ngā tuhinga te tūāpapa o te whakahaere rawa: me tiaki tika ngā hua tirotiro, ngā whakaahua āhua, ngā tuhinga whakatika, me ngā hītori whakakapinga wāhanga hei āwhina i te tātari i ngā au o te kino me te whakamahere tahua.
Te Katinga
Ehara i te mea he mahi noa te tiaki i ngā hanganga tiaki me ngā hanganga tautoko i ngā tipu hiko wai, engari he rautaki hei pupuri i te pono me te haumaru o te whakaputanga mō te wā roa. He mahi honohono tā ngā whata para, ngā puna wai, ngā awaawa ringihia, te parenga pareparenga, te waikeri, ngā hanganga whakahaere, me ngā taputapu hiki. Mā te tirotiro auau, te tiaki ārai auau, te whakamahi i ngā tikanga whakamātautau tika, me ngā tuhinga tika, ka taea e ngā tipu hiko wai te mahi pai ake, te haumaru, me te tu atu i ngā wero taiao me ngā kawenga mahi. Hei whakamutunga, ko te haumi ki te tiaki he haumi ki te haere tonu o te pūngao me te tiaki i ngā hanganga whai hua.
