Chitoliro cha mpweya wothinikizidwa
The ulamuliro khalidwe la ndondomeko unsembe mapaipi ku China makamaka zikuphatikizapo: siteji yokonzekera yomanga, siteji yomanga, siteji kuyendera, mayeso kuyendera, payipi kuyeretsa ndi siteji kuyeretsa.Ndi zofunikira zaukadaulo zomwe zikuchulukirachulukira, pakumanga kwenikweni, tiyenera kukonzekera, kukhazikitsa, kuwongolera ndi ntchito yolimbana ndi dzimbiri malinga ndi momwe zilili.
1. Kudziwa unsembe chiwembu cha ndondomeko payipi
Asanakhazikitse njira yopangira mapaipi, kuchuluka kwa ntchito yoyika ndi kumanga kuyenera kufotokozedwa molingana ndi malo oyika ndi zomangamanga komanso kapangidwe kake.Zinthu zazikuluzikulu za anthu ndi zakuthupi zomangazo zidzatsimikiziridwa podziwa momwe polojekiti ikuyendera komanso zofunikira zazikulu ndi anthu a zomangamanga.Kupyolera mu dongosolo la zinthu ndi ogwira ntchito, kugawidwa kokwanira kumachitika.Pansi pa kuonetsetsa kuti ntchito yomanga ikupita patsogolo, njira yofananirayo idzakonzedwa ndikukonzedwa kuti ipulumutse ogwira ntchito yomangayo ndikuyesetsa nthawi yomangayo, kuti apititse patsogolo kugwiritsa ntchito makina akuluakulu monga crane.
Monga nsonga yofunika kwambiri yokonzekera makonzedwe omanga, dongosolo laukadaulo limaphatikizapo: chiwembu chonyamulira cholondola komanso ntchito yowotcherera.Powotcherera zida zapadera ndikukweza mapaipi akulu akulu, mafotokozedwe aukadaulo a chiwembu chomanga ayenera kuwongolera, ndipo maziko owongolera adzatengedwa ngati maziko omanga ndi kukhazikitsa.Kachiwiri, molingana ndi ndondomeko yomanga yomwe ili ndi khalidwe ndi chitetezo, ndondomeko yomangayi ikhoza kutsimikiziridwa ndikugwirizanitsa zinthu zonse, ndipo malowa adzatsogoleredwa moyenera komanso mwadongosolo kuti amangidwe.
2. Kugwiritsa ntchito ukadaulo wopangira mapaipi pomanga
Monga njira wamba ku China, njira yopangira mapaipi iyenera kutsatiridwa chifukwa chakuya kwapang'onopang'ono komanso kutsika kwapang'onopang'ono.Mwachitsanzo, ntchito zina zomanga zimasonyeza kuti kupangidwa kwa mapaipi kuyenera kukhala oposa 40%, zomwe zimapangitsa kuti mabizinesi omanga asamavutike kwambiri malinga ndi momwe zinthu zilili.Monga ulalo kiyi wa ndondomeko unsembe payipi, kuya prefabrication akadali yosavuta prefabrication ndondomeko m'mabizinesi ambiri China.Mwachitsanzo, ndondomeko prefabrication wolunjika chitoliro chigawo ndi chigongono ndi chitoliro awiri kugwirizana ndi munthu angathe kuthetsa losavuta unsembe vuto la ndondomeko payipi.Pamene zida zapaipi zimayikidwa, sizingagwire ntchito ya prefabrication ya chitoliro.Choncho, pomanga kwenikweni, tiyenera kuganiza ndondomeko yomanga pasadakhale, ndi kukhazikitsa lolingana prefabricated chipolopolo pa unsembe udindo wa Mercury ndi kutentha exchanger pansi pa zikhalidwe.M'munda wofananira chitoliro chisanachitike, msonkhano wamunda ukamalizidwa, zolumikizira zowotcherera za gulu lofananira zimakokedwa ku chomera chofananira, ndipo zida zodziwikiratu zimagwiritsidwa ntchito mwachindunji pakuwotcherera, ndipo flange yofananira imalumikizidwa ndi mabawuti. .Chifukwa chake, ntchito yowotcherera pamanja pamalo omangayo imatha kupulumutsidwa komanso kuyika bwino kwa payipi kumatha kukulitsidwa.
