Kule mihla, ngophuhliso loqoqosho kunye nemfuno yabantu yezothutho, Isixeko ngasinye sakha umgaqo ongaphantsi kwesinye emva kwesinye,Larsen steel sheet imfumbakufuneka ibe sisixhobo sokwakha esibalulekileyo kwinkqubo yolwakhiwo lukaloliwe ohamba ngaphantsi komhlaba.
Larsen steel sheet imfumbainamandla aphezulu, uqhagamshelwano oluqinileyo phakathi kwengqumba kunye nengqumba, isiphumo esihle sokwahlula amanzi, kwaye ingaphinda isetyenziswe. Iindidi zecandelo eliqhelekileyo leemfumba zeshiti zentsimbi ubukhulu becala bubunjwe ngu-U okanye uZ. Iimfumba ze-U-shaped sheet sheet zisetyenziswa kulwakhiwo lukaloliwe oluphantsi komhlaba eTshayina. Iindlela zokuzika kunye nokususwa kwayo, ukusetyenziswa koomatshini ziyafana ne-I-steel imfumba, kodwa indlela yayo yokwakha inokohlulwa ibe yimbumba enye yentsimbi ye-cofferdam, i-double-layer steel sheet pile cofferdam kunye nekhusi. Ngenxa yomgodi wesiseko esinzulu ngexesha lokwakhiwa komzila kaloliwe ophantsi komhlaba, ukwenzela ukuba kuqinisekiswe ukuthe nkqo kwayo kunye nokwakhiwa okufanelekileyo, kwaye yenze ukuba ivalwe kwaye ivalwe, isakhiwo sesikrini sisetyenziswa kakhulu.
Larsen steel sheet ubude imfumba 12m, 15m, 18m, njl., umjelo sheet steel imfumba ubude imfumba ubude 6 ~ 9m, imodeli kunye nobude zimiselwa ngokubala. Imfumba yeshiti lentsimbi inokuqina okulungileyo. Emva kokuba ukwakhiwa komngxuma wesiseko kugqityiwe, imfumba yeshidi lentsimbi inokutsalwa kwaye isetyenziswe kwakhona. Ulwakhiwo olulula kunye nexesha elifutshane lokwakha; I-Channel steel sheet pile ayinakuvimba amanzi, kwindawo ephakamileyo yamanzi aphantsi komhlaba, ukuhlukaniswa kwamanzi okanye amanyathelo okunciphisa kufuneka kuthathwe. I-Channel steel sheet pile inekhono lokugoba elibuthathaka, elisetyenziselwa kakhulu umgodi wesiseko okanye umsele ngobunzulu ≤4m, kunye ne-anchor exhasayo okanye yokutsala kufuneka ibekwe phezulu. Ukuqina kwenkxaso kuncinci kwaye i-deformation emva kokumba inkulu. Ngenxa yobuchule bayo bokugoba obuqinileyo, i-Larsen sheet sheet yentsimbi isetyenziswa ikakhulu kubunzulu obuyi-5m ~ 8m umngxuma wesiseko oneemfuno eziphantsi zokusingqongileyo, ngokuxhomekeke kwinkxaso (yokutsala iankile) ufakelo.
