Isiteshi Sezitimela Esakhiwe Ngesivinini Esikhulu

Izakhiwo zesiteshi sesitimela esinesivinini esikhulu ezakhiwe ngensimbi zibhekisela ezakhiweni ezinkulu zezinto zokuhamba zesimanje ezisebenzisa insimbi njengento eyinhloko ethwala umthwalo futhi zihlanganise izindlela zokuthutha ezihlukahlukene ezifana nezitimela ezihamba ngesivinini esikhulu, izitimela ezihamba phakathi kwamadolobha, izitimela ezihamba ngaphansi, amabhasi namatekisi. Njengefekthri ehamba phambili yesakhiwo sensimbi e-China, singakwazi ukwenza ukujula nokwakhiwa kwezakhiwo, okungagcini nje ngokukhuphula isivinini sokukhiqiza kodwa futhi kusiza amakhasimende onge izindleko.

● Umsebenzi oyinhloko: Uhlanganisa izitimela ezihamba ngesivinini esiphezulu nezitimela.

● Umsebenzi onwetshiwe: Ukuxhumana okungenazihibe nomzila wesitimela ophakathi kwamadolobha, imizila ehamba ngaphansi, imizila emincane, amabhasi, amatekisi, izinsiza zokugibela, ngisho namabhasi amabanga amade nezindawo zokupaka izimoto ezizimele.

● Umgomo wokudizayina: Finyelela ukudluliswa kwebanga elinguziro. Abagibeli behla esitimeleni esingaphansi komhlaba noma itekisi, futhi emizuzwini embalwa ngezitebhisi ezizihambelayo noma ngezinyawo, bangangena ngokuqondile ehholo lokulinda likaloliwe wesivinini esikhulu ngaphandle kokuphuma esiteshini baphumele ngaphandle. Isibonelo, i-Shanghai Hongqiao Hub iyihabhu elihle kakhulu elihlanganisa izikhumulo zezindiza, izitimela ezihamba ngesivinini esiphezulu, imigwaqo engaphansi komhlaba, namabhasi.

Isiteshi sesitimela sendabuko vs Isiteshi sesitimela sesakhiwo sensimbi

Iziphakamiso ekukhethweni kwefomu lesakhiwo somkhiqizo

Isiteshi sehhabhu lesitimela esinesivinini esikhulu esinesakhiwo sensimbi singasebenzisa amafomu esakhiwo ahlukahlukene, futhi ngokuvamile ukukhetha kungenziwa ngokuvumelana nezimfuneko zesikhathi.

● Okwezikhala ezingaphansi kuka-60m: Uhlaka lwengqikithi lunokusebenza okungcono kakhulu kwezomnotho.

● Ngokubanzi phakathi kuka-60m no-100m: I-truss enezinhlangothi ezintathu noma i-tensioned beam.

● Ngezikhonkwane ezingaphezulu kuka-100m: Kudingeka isistimu ehlanganisiwe (efana nozimele wenetha + i-tensioned beam) iyadingeka.

FAQ

1. Zixhumeke kanjani izingxenye zesiteshi sesitimela esinesivinini esikhulu esinesivinini esikhulu esihlelekile?

Ngemuva kokuthi izingxenye ezihlukahlukene zenziwe embonini, zihanjiswa endaweni futhi zixhunywe kusetshenziswa ama-bolts aphezulu kanye ne-welding. Ngokuvamile, ngaphezu kwe-90% yamalunga axhunywe ngama-bolts aphezulu. Le ndlela yokuxhuma izinzile, iyasebenza, futhi iyashesha.

2. Yiziphi izinhlelo zesakhiwo sensimbi ezisetshenziswa kakhulu eziteshini zehabhu lesitimela esinesivinini esikhulu?

Isakhiwo segridi yesikhala

Isakhiwo se-Space truss

Isakhiwo sekhebula le-truss/suspension

Uhlaka/i-Arch structure

3. Ingabe isakhiwo sensimbi iziteshi zikaloliwe ezinesivinini esikhulu zivaliwe? Ingabe ziyayilondoloza imvelo?

Isakhiwo samanje sensimbi iziteshi zikaloliwe ezihamba ngesivinini esiphezulu zinezingqimba zokufakelwa - uboya bedwala noma uboya bengilazi bubekwe ophahleni lwensimbi, bese kufakwa usilingi ngezansi ukuze kwakheke "ibhokisi lokufakelwa elishisayo". Ngaphezu kwalokho, isakhiwo sensimbi esikhulu-span singenziwa sibe yisimo esigobile, esilungele ukufaka amaphaneli e-photovoltaic. Insimbi ingaphinda isetshenziswe kabusha futhi isetshenziswe kabusha, futhi ngemva kokudilizwa, ngeke ibe udoti wokwakha. Ngakho-ke, ngokombono wawo wonke umjikelezo wokuphila, isakhiwo sensimbi iziteshi zikaloliwe ezinesivinini esikhulu empeleni zingabamele izakhiwo eziluhlaza kanye nekhabhoni ephansi.
