I tēnei rā, ka whakamārama atu te kaihanga rama tiriti a TIANXIANG ki a koe ngā whakatūpato mōrama tiriti ā-tāonehoahoa
1. He 3P, he 4P rānei te pana matua o te rama tiriti ā-tāone?
Mena he rama o waho, ka whakatakotoria he pana turuturu hei karo i te tūponotanga o te turuturu. I tēnei wā, me whakamahi he pana 4P. Mena kāore he turuturu, ka taea te whakamahi i te pana 3P hei pana matua.
2. Ngā momo tikanga whakatakotoranga o ngā rama tiriti ā-tāone
Te tahora taha-kotahi - he pai mō ngā rori whaiti, me rite te teitei tāutanga o te rama ki te whānui whai hua o te mata o te rori, me nui ake rānei. Ko ngā painga he pai te whakakā me te iti o te utu.
Te tahora taurite - me kaua e iti iho i te 0.7 ngā wā o te whānui whai hua o te mata o te rori te teitei tāutanga o te rama.
Te tahora ōrite - me kaua e iti iho i te haurua o te whānui whai hua o te mata o te rori te teitei tāutanga o te rama.
3. Kōwhiringa whaitake o te teitei tāutanga rama tiriti, te roa o te cantilever me te koki teitei
Teitei tāutanga (h) - ko te teitei tāutanga ōhanga he 10-15m. Mēnā he iti rawa te teitei tāutanga, ka piki ake te kanapa o te rama, ā, ki te teitei rawa, ka heke te kanapa, engari ka heke te tere whakamahinga rama.
Te roa o te cantilever - kaua e neke ake i te 1/4 o te teitei o te tāutanga.
Ngā pānga o te roa rawa o te cantilever:
A. Whakaitihia te kanapa (te whakamārama) o te ara hikoi me te kōhatu ārai i te taha e tāutahia ana te rama.
B. Ka piki ake te kaha ā-pūkaha e hiahiatia ana mō te cantilever, ka pā ki te roa o te ora ratonga.
C. Ka pā ki te āhua, ka hua ake he ōwehenga kore taunga i waenga i te cantilever me te pou rama.
D. Ka piki ake te utu.
4. Te koki teitei – Kaua te koki teitei o te rama e neke ake i te 15 nekehanga
Ko te koki teitei o te rama hei whakanui ake i te whānuitanga o te māramatanga taha o te rama ki te mata o te rori. Mēnā ka nui rawa te kanapa, ka whakaitihia te kanapa o te ara puhoi me te ara hikoi.
5. Kōwhiringa utu hiko whaitake mō ngā rama tiriti ā-tāone
Ko te tikanga utu motuhake rama kotahi e whakamahia ana hei whakanui ake i te tauwehenga mana o ngā rama rerekē ki te neke atu i te 0.9, ā, ka whakaitihia te kaha o te whakawhiti hiko motuhake mō ngā rama tiriti mā te neke atu i te 51%, me te ngaronga raina mā te tata ki te 75%, he pānga nui tēnei ki te penapena pūngao.
6. Tikanga whakahaere rama tiriti
I runga i te mātāpono o te penapena pūngao mahi, ko te mahi a te nuinga o ngā tāone i ēnei rā e whaihia ana, ā, ko te tikanga whakahaere e whakakotahi ana i te whakahaere rama me te whakahaere karaka ka hangaia kia rite ki ngā whakaritenga rerekē o te whakamārama i ngā wā rerekē o te waka. Arā, i muri i te pō, i te wā e taumaha ana te waka, ka whakakāhia ngā rama tiriti katoa o te tāone hei whakarite i te haere haumaru o ngā kaihaerere me ngā waka; i muri i te waenganui pō, i te mea ka heke te rahinga o ngā waka, ka whakawetohia ngā rama tiriti katoa i tetahi taha e te whakahaere karaka, kia tutuki ai te hua penapena pūngao tino ohanga me te whakarite kia noho noa te waka.
7. Te whiriwhiri i te tikanga tohatoha mana rama
Ka taea te whakamahi i te tohatoha hiko kotahi-wāhanga mō te whakamārama whenua me te whakamārama rori me te tawhiti poto o te tuku hiko me te kawenga iti kua tatauhia, ā, me manatoko te hekenga ngaohiko me te uara iahiko poto-porowhita. Ka tangohia e te kāpata tohatoha te momo o waho, ā, ko te taha o raro he 0.3 mita i runga ake i te papa, ka tāuta ki te whenua.
Mō te tawhiti o te tuku hiko me te kawenga nui kua tatauhia, ka whakamahia te tohatoha hiko toru-wāhanga, ā, ka honoa ngā wāhanga e toru A, B, me C i roto i te ara iahiko iti-ngaohiko ki ia rōpū rama tiriti kia kore ai e taurite te taurite o ngā wāhanga e toru. Ka whakamahia te kāpata tohatoha ki te momo waho, ā, ko te taha o raro he 0.3 mita i runga ake i te papa, ā, ka tāutahia ki te whenua.
Ka taea e te ara iahiko waea-rima-wāhanga-toru o te raina ngaohiko-iti rama te whakaiti i te ngaronga ngaohiko raina ki te whakataurite ki te ara iahiko wāhanga-kotahi tuku iho.
8. Te rahi me ngā whakaritenga whakatakotoranga o te diameter paipa tiaki o ngā taura rama tiriti
Kaua te horahanga whakawhiti katoa o ngā waea i roto i te paipa tiaki e neke atu i te 40% o te horahanga whakawhiti o te paipa. Kaua te whānui o roto o te paipa e iti iho i te 1.5 ngā wā o te whānui o waho o te taura.
Ina whakatakotoria te taura ki te whitiki matomato o te ara hikoi, ko te hohonutanga o te tanumanga he 0.5 mita. I te wāhi whakawhiti, ka hurihia ki te paipa maitai D50 me te hohonutanga o te hipoki he 0.7 mita. Mena kāore e taea te whakatutuki i ngā whakaritenga o runga ake nei, ka tāpirihia he paparanga raima whakapakari c20 ki runga i te paipa.
9. Ngā mahi motuhake o te pūnaha whenua TT o ngā rama tiriti
Whakamahia he pūnaha TT ā-rohe, kāore he aho PE, ā, tāpirihia he parenga turuturu 300mA ki te ara iahiko pakaru hiko e puta atu ana. Me hono pūmau ngā pou rama me ngā rama katoa ki ngā pae maitai o te turanga pou rama hei taputapu whenua, hei ātete whenua.
10. Me pēhea te whiriwhiri i tētahi whakawhiti hiko i runga i te kawenga kua tatauhia i roto i te hoahoa rama tiriti
Ehara te kaha o te whakawhiti hiko i te raruraru, ko te mea nui ko te radius o te pūtake hiko. I roto i te hangarau, ko te radius o te pūtake hiko o te whakawhiti hiko pouaka rama tiriti he tata ki te 700 (ki te hiahia koe kia tika, me tatau e koe te hekenga ngaohiko), nō reira he nui te whakawhiti hiko kotahi mō te 1.5 kiromita, ā, e taunakihia ana kia whakamahia kia 3 ngā whakawhiti hiko pouaka rama tiriti mō te 4.225 kiromita. Ko te kaha e whakawhirinaki ana ki te mana katoa o ngā rama tiriti e tukuna ana e te whakawhiti hiko, me te 50% rahui (ko ētahi rori matua me whai rama pānuitanga, me whai hiko rahui rānei mō ngā rama tiriti whakawhiti hiko).
