Ingqokelela yentsimbi kaLarsen idlala njani inzuzo kwindlela engaphantsi komhlaba?

Kule mihla, ngenxa yophuhliso loqoqosho kunye nemfuno yabantu yezothutho, isixeko ngasinye sakha i-metro emva kwesinye,Inqwaba yeshiti yentsimbi yaseLarsenkufuneka zibe zizinto zokwakha ezibalulekileyo kwinkqubo yokwakhiwa kwesitimela esingaphantsi komhlaba.

Inqwaba yeshiti yentsimbi yaseLarseninokuqina okuphezulu, unxibelelwano oluqinileyo phakathi kwenqwaba kunye nenqwaba, isiphumo esihle sokwahlulwa kwamanzi, kwaye inokusetyenziswa kwakhona. Iintlobo eziqhelekileyo zeengqokelela zesinyithi zentsimbi ikakhulu zimilo-U okanye u-Z. Iingqokelela zesinyithi zentsimbi ezimilo-U zisetyenziswa ekwakheni oololiwe abangaphantsi komhlaba eTshayina. Iindlela zayo zokuntywila nokususa, ukusetyenziswa koomatshini kuyafana nengqokelela yentsimbi ye-I, kodwa indlela yayo yokwakha inokwahlulwa ibe yingqokelela yesinyithi yentsimbi ye-cofferdam, ingqokelela yesinyithi yentsimbi ye-cofferdam kunye nesikrini. Ngenxa yomngxuma wesiseko onzulu ngexesha lokwakhiwa koololiwe abangaphantsi komhlaba, ukuqinisekisa ukuba imile ngokuthe nkqo kwaye ilungele ukwakhiwa, kwaye ikwazi ukuvalwa nokuvalwa, isakhiwo sesikrini sisetyenziswa kakhulu.

Ubude benqwaba yesinyithi seLarsen yi-12m, 15m, 18m, njl.njl., ubude benqwaba yesinyithi setshaneli yi-6 ~ 9m, imodeli kunye nobude bumiselwa ngokubalwa. Inqwaba yesinyithi sentsimbi inokuqina okuhle. Emva kokuba ukwakhiwa komngxuma wesiseko kugqityiwe, inqwaba yesinyithi sentsimbi inokutsalwa kwaye iphinde isetyenziswe kwakhona. Ukwakhiwa okulula kunye nexesha elifutshane lokwakha; Inqwaba yesinyithi setshaneli ayinakuvala amanzi, kwindawo enamanzi angaphantsi komhlaba aphezulu, kufuneka kuthathwe amanyathelo okuvalela amanzi okanye imvula. Inqwaba yesinyithi setshaneli inamandla okugoba abuthathaka, asetyenziswa kakhulu kumngxuma wesiseko okanye umsele onobunzulu obuyi-≤4m, kwaye kufuneka kubekwe i-ankile exhasayo okanye etsalayo phezulu. Ukuqina kwenkxaso kuncinci kwaye ukuguquguquka emva kokumba kukhulu. Ngenxa yekhono layo elinamandla lokugoba, inqwaba yesinyithi seLarsen isetyenziswa kakhulu kumngxuma wesiseko onzulu we-5m ~ 8m oneemfuno eziphantsi zokusingqongileyo, kuxhomekeke kufakelo lwenkxaso (i-ankile yokutsala).
