Ukufakwa kweshidi lensimbinoma inqwaba yeshidi lensimbi, iyinto yokwakha evame ukusetshenziswa kumaphrojekthi ahlukahlukene. Yenziwe ngensimbi yekhabhoni, isebenza njengesixazululo esiguquguqukayo nesihlala isikhathi eside sokugcina izindonga, ukumba okwesikhashana, ama-cofferdams, nezinye izinhlelo zokusebenza eziningi.
Usayizi wezinqwaba zensimbi ezimise okwe-U ungenziwa ngokwezifiso ngokwezidingo ezithile. Osayizi abavamile bahlanganisa:
Ububanzi benqwaba yensimbi enomumo we-U (B): ngokuvamile phakathi kuka-300mm no-600mm;
Ukuphakama (H) kweIzinqwaba zensimbi ezimise okwe-U: ngokuvamile phakathi kuka-100mm no-400mm;
Ubukhulu benqwaba yensimbi enomumo we-U (T): ngokuvamile phakathi kuka-8mm no-20mm.
Kufanele kuqashelwe ukuthi izimo ezahlukene zokusetshenziswa kanye nezidingo ezithile zephrojekthi zingaba nemininingwane yosayizi ehlukene. Ngakho-ke, lapho ukhetha usayizi wezinqwaba zensimbi ezimise okwe-U, ukubonisana nokuqinisekisa kufanele kusekelwe ezimweni ezithile.
Inzuzo yokusebenzisa inqwaba yeshidi lensimbi isemandleni ayo kanye nokuzivumelanisa nezimo. Ukwakheka kwayo okuxhumene kuvumela isakhiwo esivikelekile nesizinzile, esikwazi ukumelana nemithwalo esindayo kanye nezingcindezi. Kungakhathaliseki ukuthi senzelwe izakhiwo ezihlala njalo noma zesikhashana, inqwaba yeshidi lensimbi iqinisekisa ukuzinza kanye nobuqotho bephrojekthi.
Enye yezinzuzo eziyinhloko zokufakwa kweshidi lensimbi ukumelana nokugqwala. Insimbi yekhabhoni esetshenziswa ekwakhiweni kwayo inikeza ukuqina okuhle kakhulu kanye nokuphila isikhathi eside, okwenza kube kuhle kakhulu ukusetshenziswa ezindaweni zasolwandle noma ezindaweni ezinomswakama ophezulu. Ngokugwema ukugqwala, ukufakwa kweshidi lensimbi kunciphisa isidingo sokulungiswa okubizayo kanye nokufakwa esikhundleni, okuhlinzeka ngezixazululo ezisebenzayo nezingabizi kakhulu.
Ukuguquguquka kokufakwa kweshidi lensimbi kudlulela nasezindleleni zalo zokufaka. Ingafakwa ngokushayela, ukudlidliza, noma ukucindezela, kuye ngezidingo ezithile zephrojekthi. Lokhu kuguquguquka kuvumela izinqubo zokwakha eziphumelelayo neziphumelelayo, kunciphisa kokubili isikhathi kanye nezindleko zabasebenzi.
Ekuphetheni, ukunqwabelanisa amashidi ensimbi kunikeza izinzuzo eziningi ekwakheni. Amandla ayo, ukumelana nokugqwala, kanye nokuguquguquka kwayo kwenza kube yisisombululo esithembekile nesingabizi kakhulu sezinhlelo zokusebenza ezahlukahlukene. Ngaphezu kwalokho, ukuguquguquka kokufakwa kwayo kanye nesimo sayo esiqhubekayo kunegalelo ekukhangeni kwayo njengezinto zokwakha. Kungakhathaliseki ukuthi kungokwezakhiwo zesikhashana noma ezihlala njalo, ukunqwabelanisa amashidi ensimbi kunikeza isisekelo esiqinile samaphrojekthi aphumelelayo.
