Iyini isipiliyoni sohlelo lokusebenza lwenqwaba yamashidi ensimbi agingqike ashisayo kumaphrojekthi echweba?

Izinqwaba zamashidi ensimbi agingqiwe ashisayo seziyingxenye ebalulekile yamaphrojekthi echweba ngenxa yesipiliyoni sazo esihle kakhulu sohlelo lokusebenza. Izinqwaba zamashidi e-Larsen ziyinketho yokuqala uma kuziwa ekutholeni izinqwaba zamashidi ezisezingeni eliphezulu zokwakhiwa kwechweba. Itholakala ngezinketho ezahlukahlukene, kufaka phakathi Uhlobo 2 kanyeThayipha inqwaba yeshidi elingu-4, le mikhiqizo inikeza ukuqina, amandla kanye nokusebenza kahle kwezindleko, okuyenza ibe ukukhetha kokuqala kumaphrojekthi wokuthuthukiswa kwechweba.
Izinqwaba zamashidi e-Larsen ezidayiswayo zidingeka kakhulu ngenxa yerekhodi elifakazelwe le-Larsen sheet piles ekwakhiweni kwechweba. Yaziwa ngamandla ayo akhethekile nokuguquguquka, inqwaba yeshidi Uhlobo 2 luyinketho edumile yezinhlelo zokusebenza zamachweba. Ikhono layo lokumelana nemithwalo ephezulu futhi linikeze ukwesekwa okuthembekile kwenza kube yisixazululo esikahle sezindonga zedokhi, ama-bulkheads nezinye izakhiwo zasolwandle.Intengo yenqwaba yeshidi Uhlobo 2iyaqhudelana futhi iyindlela engabizi kakhulu yonjiniyela bechweba abafuna ukukhulisa utshalomali lwabo.
Ngokunjalo, izinqwaba zamashidi ohlobo 4 zinikeza ukusebenza okuhle kakhulu kumaphrojekthi echweba. Ukwakheka kwayo okumazombezombe kanye nendlela ephakeme yokuhlangana kuyenza ifanelekele ukumelana nezindawo zasolwandle ezinokhahlo. Intengo yenqwaba yamashidi yohlobo 4 ehambisana nokuqina kwayo kwesikhathi eside iwenza abe ukukhetha okuhle kakhulu kumaphrojekthi wokwakha amachweba lapho kubaluleke kakhulu ukuphila isikhathi eside nokwethembeka.

Isipiliyoni sohlelo lokusebenza lwezinqwaba zeshidi lensimbi eligoqelwe ngokushisayo kumaphrojekthi wechweba liyamangalisa. Lezi zinqwaba zamashidi zinikeza isisekelo esiqinile sengqalasizinda yechweba, ehlinzeka ngokuzinza kanye nobuqotho besakhiwo ezimweni zasolwandle eziyinselele. Ukufakwa kwabo kalula kanye nekhono lokuhlangabezana nezidingo ezahlukahlukene zokuklama kubenza babe ukukhetha kokuqala konjiniyela bechweba nonjiniyela.
Ngamafuphi, ukusetshenziswa kweLarsen ishidi izinqwaba(kuhlanganise nohlobo 2 no-4) ithuthukise kakhulu isipiliyoni sohlelo lokusebenza lwenqwaba yamashidi ensimbi agingqike ashisayo kumaphrojekthi echweba. Ukumakethwa kwabo, amanani ancintisanayo kanye nokusebenza okuqinisekisiwe kubenza babe ukukhetha okuhle kakhulu konjiniyela bechweba abafuna isixazululo esithembekile nesingabizi kakhulu. Ngokuhlala kwayo okungenakuqhathaniswa nokuguquguquka, izinqwaba zamashidi e-Larsen ziyaqhubeka nokubamba iqhaza elibalulekile ekulolongeni ikusasa lamaphrojekthi wokwakha amachweba.
