Ngabe inqwaba yeshidi lensimbi ye-Larsen idlala kanjani inzuzo esitimeleni esingaphansi komhlaba?

Ezinsukwini zanamuhla, ngokuthuthuka komnotho kanye nesidingo sabantu sezokuthutha, idolobha ngalinye lakha ujantshi wesitimela ngokulandelana, inqwaba yamashidi ensimbi iLarsen kumelwe ibe impahla yokwakha ebalulekile lapho kwakhiwa umzila ohamba ngaphansi komhlaba.

Inqwaba yeshidi lensimbi ye-Larsen inamandla amakhulu, ukuxhumana okuqinile phakathi kwenqwaba nenqwaba, umphumela omuhle wokuhlukanisa amanzi, futhi ingasetshenziswa kabusha. Izinhlobo zesigaba ezivamile zezinqwaba zamashidi ensimbi ngokuvamile zimise okwe-U noma ezimise okwe-Z. Izinqwaba zensimbi ezimise okwe-U zisetshenziswa ekwakhiweni kukaloliwe ongaphansi komhlaba eChina. Izindlela zayo zokucwila nokususa, ukusetshenziswa kwemishini ziyafana nenqwaba ye-I-steel, kodwa indlela yayo yokwakha ingahlukaniswa ibe yinqwaba yensimbi yongqimba olulodwa yensimbi, i-double-layer steel sheet sheet cofferdam kanye nesikrini. Ngenxa yomgodi ojulile wesisekelo ngesikhathi kwakhiwa ujantshi ongaphansi komhlaba, ukuze kuqinisekiswe ukuma kwawo kanye nokwakhiwa okulungile, futhi ukwenze kungavalwa futhi kuvalwe, isakhiwo sesikrini sisetshenziswa kakhulu.

I-Larsen steel sheet inqwaba ubude 12m, 15m, 18m, njll, isiteshi steel sheet inqwaba inqwaba ubude 6 ~ 9m, imodeli nobude kunqunywa ukubala. Inqwaba yeshidi lensimbi inokuqina okuhle. Ngemva kokuqedwa kokwakhiwa komgodi wesisekelo, inqwaba yeshidi lensimbi ingakhishwa bese igaywa kabusha futhi. Ukwakhiwa okulula kanye nesikhathi sokwakha esifushane; Inqwaba yeshidi lensimbi yeshaneli ayikwazi ukuvimba amanzi, endaweni enezinga eliphezulu lamanzi angaphansi komhlaba, ukuhlukaniswa kwamanzi noma izinyathelo zemvula kufanele kuthathwe. Inqwaba yeshidi lensimbi yesiteshi inekhono lokugoba elibuthakathaka, elisetshenziselwa kakhulu umgodi wesisekelo noma umsele onokujula okungu-≤4m, futhi ihange elisekelayo noma elidonsayo kufanele limiswe phezulu. Ukuqina kokusekelwa kuncane futhi ukuguqulwa ngemuva kokumba kukhulu. Ngenxa yekhono layo eliqinile lokugoba, inqwaba yeshidi lensimbi ye-Larsen isetshenziswa kakhulu umgodi wesisekelo ojulile ongu-5m~8m onezidingo eziphansi zemvelo, kuye ngokusekelwa (donsa ihange).
