Te tukanga whakaputa puranga maitai
1. Te Whakamahana Pire
TukangaKa whāngaihia te parai ki roto i te oumu whakamahana, ka whakamahanatia ki te 1200°C - 1300°C. Mā tēnei pāmahana teitei ka pai te kirihou o te maitai, ka āwhina i te hurihanga nui.
2. Te Whakatakoto me te Hanga-mua
TukangaKa haere te paraoa wera i roto i te mira huri. Mā roto i ngā hurihanga maha, ka angiangi haere te paraoa, ka roa haere, ā, ka pēhia tuatahitia kia rite ki te āhua "U".
3. Te Hurihuri Ao Whānui
TukangaKoinei te taahiraa tino nui. Ka uru te pereki ki roto i te mira hurihuri whānui. Ka whakahaere tika te mira hurihuri i te matotoru o te flange, te matotoru o te tukutuku, me te teitei o ngā puranga rau āhua-U mā te mahi tahi o ngā roera whakapae me te poutū.
4. Te Whakatikatika me te Tapahi
Te tapahi ki te roaE ai ki ngā whakaritenga a te kiritaki (hei tauira, 6m, 9m, 12m, 15m), ka tapahia ngā puranga pepa kia rite te roa mā te whakamahi i te kani rere, i te kaitapahi mura rānei.
5. Whakamatao me te Tirotiro
TukangaKa whakamataohia ngā puranga rau i runga i te moenga whakamatao.
6. Te Whakakī me te Tākai i te Hinu Maukati
Te TiakitangaHei ārai i te waikura o ngā raka i te wā e kawe ana, e penapena ana hoki, ā, hei whakahaere i ngā mahi poupou, ka pania te hinu ki ngā raka.
Mata Puranga Rau Rino
Amerika:HDG hei ASTM A123 (paninga konutea iti rawa ≥ 85 µm); he kōwhiringa te paninga 3PE; he rite ngā whakaotinga katoa ki te RoHS.
Āhia ki te Tonga-mā-rāwhitiHe paparanga matotoru o te whakapūkara wera-tuku (≥100μm) me te paninga tāra waro epoxy takirua e whakarato ana i te tiaki rehu tote neke atu i te 5000 hāora, he mea e tika ana mō te whakamahi i roto i te taiao moana pārūrū.
TONO
1. Te Whakapūmau i te KeriI ngā ratonga o te tāone, i te keri teihana tereina raro whenua, i te hanga rūma raro whenua rānei, ka whaowhina ngā pou rino āhua-U ki roto i te oneone hei hanga i ngā pakitara pupuri oneone rangitahi, pumau rānei, i ngā pakitara mahi rānei.
2. Ngā TāmihanaMō te hanganga piriti-pou, mō ngā mahi i raro i te wai rānei, ka honoa ngā pou rino āhua-U ki te taha whakapae, ki te taha poutū hoki hei hanga i tētahi mowhiti kati (cofferdam).
3. Te Hanga Moana me te TaurangaKa whakamahia hoki ngā pou rino āhua-U hei ārai mō ngā pakitara o te tauranga.
4. Te Whakahaere Waipuke me ngā Ārai ParewaiI roto i te whakapakari i ngā tāpae me te whakahaere awa, ka tanumia ngā pou rino āhua-U ki roto i te wai hei ārai ātete-uru.
Ngā painga o ngā puranga āhua-U
1. Te ōwehenga Kaha-ki-Taumaha Hanganga Pai rawa atu
Mā te hoahoa ātaahua o te āhua-U ka whakanuia te tawhiti i waenga i te maitai me te tuaka kūpapa, ka tino whakanuia te modulus wāhanga.
2. Te Mahi Honohono me te Āraiwai Pai Rawa
Ka whakamahia e ngā pou-U te pūnaha raka a Larssen, e mōhiotia whānuitia ana mō tōna pono.
3. Te Tāutanga me te Whakahaere Ngāwari
He māmā ake te whakahaere i ngā pou-U ki te whakaritea ki ētahi atu kōtaha uaua, pērā i ngā pou-Z, i ngā pakitara hiato rānei.
4. Te Whakamahinga Anō Teitei me te Whānuitanga
Ka taea te whakamahi i ngā pou-U hei tautoko rangitahi, hei hanganga tuturu rānei. Ka taea te whakaroa i tōna roa mā te whakarewa, te whakapoto rānei mā te tapahi kia tutuki ai ngā whakaritenga motuhake o te wāhi.
TE TĀKAI ME TE TUKU
TākaiHe mea hono, he mea here tahi, he mea whakau ki ngā whitiki rino, ā, kua pania ngā koropiko raka ki te hinu hei ārai i te waikura.
Te kawe waka: Tautoko ana i te ipu, te ipu tuwhera-runga, te tuku utaina nui rānei.
Te tapangaKei ia kete he Tiwhikete Rauemi taketake (MTC) me te tapanga whakatakotoranga.
Ngā Pātai Auau
Q1: He aha te momo raka e whakamahia ana e koe? He ngāwari ki te wetewete?
A: E whakamahi ana mātou i ngā hononga Larssen paerewa. Mā te tukanga hurihuri wera ka tino tika te rahinga me te piri o te hononga, ā, ka ārai i te wetewete.
P2: Kei te haere mai te hua me te Tiwhikete Rauemi (MTC)?
A: Kei ia puranga hua he Tiwhikete Rauemi taketake (MTC), e kapi ana i te hanganga matū me te whakamātautau mahi miihini.
Q3: He whakaritenga roa motuhake tāku (hei tauira, 13.5 mita), ka taea e koe te whakarite?
Āe. Ka tukuna e mātou he ratonga roa kua whakaritea. Haunga ngā 6m, 9m, me te 12m paerewa, ka taea hoki e mātou te tapahi tika kia rite ki tāu hoahoa, ka whakaiti i te whakarewanga i te papaanga, i te para rānei.
P4: Mena kei te āwangawanga ahau mō ngā turuturu, ka taea e koe te tāpiri i mua i te hiri raka?
A: Kāore he raruraru. Ka taea e mātou te tāpiri i mua i te hiri honohono ngaio (pēnei i a Wadit) i mua i te tukunga kia rite ki ō hiahia, ka taea rānei te whakarato i te maimoatanga hinu honohono hei whakarite i te aukati pai o te turuturu i roto i ngā mahi wai, i ngā kaupapa tāwharau rānei.
