Hangarau Taupānga
1. Te hangarau whenua me te hangarau tautoko punga GFRP
Ko ngā kaupapa kauhanga, pari me raro whenua ka uru ki te punga whenua, he maha ngā wā ka whakamahia te rino kaha kume hei tokotoko punga mō te punga, he pai te ātete ki te waikura o te pae GFRP i roto i ngā āhuatanga whenua kino mō te wā roa, he pai te ātete ki te waikura o te pae GFRP hei utu mō ngā tokotoko punga rino, kāore e hiahiatia he maimoatanga waikura, he kaha kume, he māmā, he ngāwari ki te hanga, he pai ki te kawe me te tāuta. I tēnei wā, kei te piki haere te whakamahinga o te pae GFRP hei tokotoko punga mō ngā kaupapa hangarau whenua. I tēnei wā, kei te piki haere te whakamahinga o ngā pae GFRP hei tokotoko punga i roto i te hangarau whenua.
2. Hangarau aroturuki atamai pae GFRP whaiaro-whakauru
He maha ngā painga ahurei o ngā pūoko whatu muka i ngā pūoko kaha tuku iho, pērā i te hanganga māmā o te pane pūoko, te rahi iti, te mama, te kaha ki te whakahoki, te aukati i te wawaotanga hiko-aukati, te aro nui, te āhua rerekē me te kaha ki te whakauru ki roto i te pae GFRP i roto i te tukanga whakaputa. Ko te Pae Atamai LU-VE GFRP he huinga o ngā pae LU-VE GFRP me ngā pūoko whatu muka, he roa te mau, he tere ora pai te whakatinanatanga me ngā āhuatanga whakawhiti taumahatanga aro, he pai mō te miihini ā-iwi me ētahi atu mara, tae atu ki te hanga me te ratonga i raro i ngā āhuatanga taiao kino.
3. Hangarau whakapakari raima tapahi ārai
Hei ārai i te urunga mai o te wai, te oneone rānei i raro i te mana o te pēhanga wai nā te tangohanga horihori o te whakakaha maitai i roto i te raima i roto i te hanganga o te ara raro whenua, i waho o te pakitara aukati wai, me whakakī e ngā kaimahi he oneone matotoru, he raima noa rānei. E kore e kore ka whakanuia e tēnei mahi te kaha o te mahi a ngā kaimahi me te wā huringa o te keri kauhanga i raro whenua. Ko te otinga ko te whakamahi i te whare herehere pae GFRP hei utu mō te whare herehere maitai, ka taea te whakamahi i roto i te hanganga raima o te whare herehere pito raro whenua, ehara i te mea ko te kaha kawe anake ka taea te whakatutuki i ngā whakaritenga, engari nā te mea he painga tō te hanganga raima pae GFRP ka taea te tapahi i roto i te mīhini whakangungu rakau (TBM) e whiti ana i te whare herehere, ka tino whakakorea te hiahia mō ngā kaimahi ki te haere ki roto, ki waho hoki i ngā awa mahi i ngā wā katoa, ka taea te whakatere i te tere o te hanganga me te haumaru.
4. Hangarau tono ara GFRP pae ETC
Kei roto i ngā ara ETC o nāianei te ngaronga o ngā mōhiohio mō te ara, tae atu ki te tangohanga maha, te pokanoa ki ngā rori tata, te tukuake maha o ngā mōhiohio tauwhitinga me te rahunga tauwhitinga, me ētahi atu. Mā te whakamahi i ngā pae GFRP kore-aukume me te kore-arataki hei utu mō te maitai i roto i te papa ka taea te whakaroa i tēnei āhuatanga.
5. Papa raima whakapakari tonu GFRP
Ko te papa raima whakapakari tonu (CRCP) he pai te taraiwa, he kaha te pikau, he pakari, he ngāwari te tiaki me ētahi atu painga nui, ko te whakamahinga o ngā pae whakakaha muka karāhe (GFRP) hei utu mō te maitai i whakamahia ki tēnei hanganga papa, hei whakakore i ngā ngoikoretanga o te waikura ngāwari o te maitai, engari hei pupuri hoki i ngā painga o te papa raima whakapakari tonu, me te whakaiti i te ahotea i roto i te hanganga papa.
6. Hangarau tono raima anti-CI mō te pae GFRP i te ngahuru me te hotoke
Nā te mea he mea noa te whakamahi hukapapa i ngā rori i te takurua, ko te tango hukapapa tote tētahi o ngā huarahi tino whai hua, ā, ko ngā katote pūhaumāota ngā tino take o te waikura o te maitai whakakaha i roto i te papa raima whakakaha. Mā te whakamahi i ngā pae GFRP e ātete ana ki te waikura hei utu mō te maitai, ka roa ake te ora o te papa.
7. Hangarau whakapakari raima moana pae GFRP
Ko te waikura hauota o te whakakaha maitai te mea tino nui e pā ana ki te pakari o ngā hanganga raima whakakaha i roto i ngā kaupapa takutai moana. Ko te hanganga pereti-pereti whānui e whakamahia ana i ngā taunga tauranga, nā tōna taumaha me te kawenga nui e mau ana, ka pāngia e ngā nekehanga piko nui me ngā kaha kutikuti i roto i te whānui o te pereti roa me te tautoko, ka puta ai ngā kapiti. Nā te mahi a te wai moana, ka taea te waikura i ēnei pae whakakaha ā-rohe i roto i te wā poto rawa, ka hua ake te whakahekenga o te kaha kawe o te hanganga whānui, ka pā ki te whakamahinga noa o te tauranga, tae noa ki te puta o ngā aituā haumaru.
Te whānuitanga o te tono: taiapa moana, hanganga whare tahataha, roto ahumoana, ākau horihori, hanganga pakaru wai, tauranga mānu
me ētahi atu
8. Ētahi atu whakamahinga motuhake o ngā pae GFRP
(1) Te tono motuhake mō te ārai i te pokanoa hikohiko
Ka taea te whakamahi i ngā whare taunga rererangi me ngā whare hōia, pērā i ngā taputapu ārai-radar, ngā whare whakamātautau taputapu hōia tairongo, ngā pakitara raima, ngā taputapu MRI o te wāhanga hauora, te whare tirotiro geomagnetic, ngā whare hanumi karihi, ngā pourewa whakahau taunga rererangi, me ētahi atu, hei whakakapi mō ngā pae rino, ngā pae parahi, me ētahi atu. Ko ngā pae GFRP hei rauemi whakapakari mō te raima.
(2) Ngā hononga papa pakitara hanawiti
Ko te pakitara pakitara kua oti te hanga he mea hanga ki te hauhautanga hanawiti, he mea hanga mai i ngā taha raima e rua me te paparanga ārai i waenganui. E whakamahia ana e te hanganga ngā hononga rauemi hiato kua whakapakarihia ki te muka karāhe (GFRP) OP-SW300 hou mā te papa ārai wera hei hono i ngā taha raima e rua, kia kore ai e whakamahia ngā piriti makariri i roto i te hanganga e te pakitara ārai wera. Ehara i te mea ka whakamahia noa e tēnei hua te kawe hiko kore-wera o ngā uaua LU-VE GFRP, engari ka tino whai hua hoki te pānga whakakotahi o te pakitara hanawiti.
