Mai i ngā whare teitei ki ngā piriti whakawhiti moana, mai i ngā waka rererangi ki ngā wheketere atamai, kei te hangaia anō e te hanganga maitai te mata o te hangarau hou me tana mahi tino pai. Hei kaikawe matua o te hanganga ahumahi, ehara i te mea ko te hanganga maitai anake te kawenga mō te taumaha o te wāhi tūturu, engari e whakaata ana hoki i te whakaaro nui o te pūtaiao rauemi tangata me te hangarau hangarau. Ka tātarihia e tēnei tuhinga te mea ngaro o tēnei "anga maitai" mai i ngā taha e toru: ngā āhuatanga rauemi mata, te auahatanga tukanga hanga, me te whānui o te mara tono.
1. Te whanaketanga o te maitai: te putanga hou o te mahi a ngā rauemi mata
Ko te pūtake o te hanganga maitai hou kei roto i te auahatanga tonu o ngā rauemi. WaroHanganga Whare(raupapa Q235) tonu te whiringa tuatahi mō te anga o ngā whare ahumahi me ngā whare noa nā tōna ngāwari ki te whakarewa me te ōhanga; i te mea ka whakanui ake te maitai kaha-teitei o te koranu iti (Q345/Q390) i te kaha whakaputa mā te neke atu i te 50% mā te tāpiri i ngā huānga iti pēnei i te vanadium me te niobium, ka noho ko te "mana" o te ngongo matua o ngā whare tino teitei.
2. Te Huringa Hanga Atamai: Te Tukanga Whakaputa Tika
I raro i te ngaru o te mamati, kua hangaia e te hanganga maitai he pūnaha atamai tukatuka-katoa:
Te tapahi atamai: Ka whakairohia e te mīhini tapahi taiaho ngā āhua o ngā wāhanga uaua ki runga i te pereti maitai me te tika o te 0.1mm;
Te whakarewa karetaoKa mahi tahi te ringa karetao tuaka-ono me te pūnaha pūoko tirohanga hei whakatutuki i te hanganga whakarewa tonu mō ngā haora 24;
Tāutanga-mua mō ngā momotuhiMā te hangarau BIM, ka tutuki i te whatunga maitai 18,000-tana o te taunga rererangi o Beijing Daxing te huihuinga kore-hapa o ngā tekau mano o ngā wāhanga.
He mea tino nui te whanaketanga o te hangarau hononga matua:
Hononga pūtu kaha-teitei: Ka eke te utaina pūtu 10.9S-grade ki te 1550MPa, ā, 30,000 ngā pūnga o te Pourewa o Shanghai e whakamahi ana i te hononga waku;
3. Taupānga Whakawhiti-Rohe: Mana Rino Mai i te Ao ki te Wāhi Hōhonu
Te mara hangarau hangahanga:
Ko te Pourewa o Shanghai, 632 mita te roa, e whakamahi ana i te pakitara ārai paparua me te pūnaha anga nunui, ā, e 85,000 tana o te maitai e whakamahia ana hei whatu i tētahi "tāone poutū";
Mara hanganga:
Ko te pourewa matua o te Huarahi Matua me te Piriti Rerewē o te Awa Yangtze o Shanghai-Suzhou-Jiangyin he mea hanga ki te maitai piriti Q500qE, ā, ko te taura piko kotahi e pikau ana i te 1,000 tana;
He rino te hanganga o te whare tipu o raro whenua o te Teihana Hiko Wai o Baihetan, ā, ka taea e ia te tu atu ki te whakamātautau o te 24 miriona tana o te pana wai.
Whakamutunga
Te hītori oNgā Hanganga RinoKo te whanaketanga he hītori o te auahatanga e werohia ai e te tangata ngā rohe o te ahupūngao. I Haina, kua neke atu i te 30% te rongonui o ngā whare kua oti te hanga, ā, i ēnei rā kua tutuki te ariā o ngā ararewa ātea, mā te tukinga o te maitai me te whakaaro nui ka hanga he ātea kaha ake, he māmā ake, he pumau ake hoki mō te heke mai.
