Izinqwaba zeshidi lensimbi eligoqiwe elishisayo: izicelo eziningi kubunjiniyela bomphakathi

Izinqwaba zamashidi ensimbi agingqiwe ashisayo, njengenqwaba yeshidi lensimbi edumile i-Larsen, iyingxenye ebalulekile yemiklamo ehlukahlukene yobunjiniyela bomphakathi.Lezi zingxenye zenqwaba yeshidi lensimbi zitholakala ngezinhlobo ezahlukene ezihlanganisaUthayipha inqwaba yeshidikanye nenqwaba yeshidi le-Z futhi asetshenziswa kakhulu ekwakheni ngenxa yokuqina kwawo, amandla nokuguquguquka.Ngakho-ke, abahlinzeki benqwaba yamashidi ensimbi badlala indima ebalulekile ekuhlinzekeni lezi zinto ezibalulekile embonini yezokwakha.
Ukusetshenziswa kabanzi kwezinqwaba zamashidi asongwe ashisayo kubunjiniyela bomphakathi kuyamangalisa ngempela.Lezi zinqwaba zivame ukusetshenziswa ekwakhiweni kwezindonga zokugcina, ama-cofferdam kanye nama-bulkheads.Ikhono labo lokumelana nengcindezi ebalulekile kanye nokuhlinzeka ngosizo lwesakhiwo libenza balungele ukusungula izisekelo ezizinzile ezindaweni ezinezimo zenhlabathi eziyinselele.Ngaphezu kwalokho,inqwaba yensimbi egoqiwe eshisayo yohlobo 2zivame ukusetshenziswa ekuthuthukisweni kwezakhiwo ezingaphansi komhlaba njengezindlu zangaphansi kanye nezindawo zokupaka izimoto ezingaphansi komhlaba njengesithiyo esisebenzayo ngokumelene nokungena kwenhlabathi namanzi.

Enye yezinzuzo eziyinhloko zenqwaba yeshidi lensimbi eshisayo iwukuba lula kwayo ukufakwa.Idizayini yabo ehlanganisiwe ivumela ukuhlangana okusheshayo nokuphumelelayo, ukunciphisa isikhathi sokwakha kanye nezindleko.Lokhu kubenza babe ukukhetha okukhangayo kumaphrojekthi wobunjiniyela bomphakathi ahlukahlukene, kusukela ekuthuthukisweni kwezindawo zokuhlala ezincane kuya ezinhlelweni ezinkulu zengqalasizinda.
Ukwengeza, ukuguquguquka kwezinhlobo zenqwaba yeshidi lensimbi kuyenza ifaneleke kokubili izinhlelo zokusebenza zesikhashana nezihlala unomphela.Kungakhathaliseki ukuthi ezokugcinwa okwesikhashana phakathi nokwakhiwa noma ukusetshenziswa isikhathi eside ezindaweni zasolwandle, izinqwaba zamashidi agoqwe ashisayo zinikeza izixazululo ezinokwethenjelwa ezinseleleni ezihlukahlukene zobunjiniyela.
Kafushane, ukubaluleka kwe-hot-rolledizinqwaba zeshidi lensimbikwezobunjiniyela bomphakathi akunakushiwo ngokweqile.Amandla azo, ukuqina kwawo, nokuvumelana nezimo kuwenza abaluleke kakhulu emisebenzini eyahlukahlukene yokwakha.Njengoba isidingo salezi zinto siqhubeka sikhula, abahlinzeki benqwaba yamashidi ensimbi badlala indima ebalulekile ekuhlinzekeni ngemikhiqizo esezingeni eliphezulu ukuze kuhlangatshezwane nezidingo zemboni yezokwakha.Ngokusetshenziswa kwazo okuhlukahlukene kanye nokusebenza okuqinisekisiwe, izinqwaba zamashidi ensimbi agingqiwe ashisayo zisethelwe ukuthi ziqhubeke nokuba yisisekelo sobunjiniyela bomphakathi eminyakeni ezayo.
