Mu myaka ya vuba aha, bitewe n’iterambere ryihuse ry’ubwubatsi bw’imijyi n’ubwiyongere bw’ubukene ku butaka,Ibirundo by'icyuma bifite ishusho ya UByakunzwe cyane kandi bikoreshwa nk'ibikoresho by'ubwubatsi bw'ibikorwa remezo binoze kandi birambye. Imiterere yihariye n'imikorere myiza y'imitako y'icyuma yo mu bwoko bwa U bituma iba amahitamo mashya mu bijyanye n'ubwubatsi bushya.
Mbere na mbere, imigozi ya U steel ifite imbaraga nyinshi kandi ihamye. Ikozwe mu cyuma cyiza kandi imiterere yayo yihariye ifite ishusho ya U ituma ishobora kwihanganira imbogamizi zo mu turere dutandukanye tw’isi n’ubutaka. Ku bijyanye no kurwanya imitingito no kurwanya umuyaga, sheet pile u type igaragaza imikorere myiza cyane, itanga icyizere gikomeye cy’uko inyubako ihamye kandi yizewe.
Icya kabiri, umuvuduko w'inyubako yaIbirundo by'impapuro zishyushye zizungurutse bifite ishusho ya Uni vuba kandi byoroshye. Ugereranyije n'inkuta za sima zisanzwe, ikirundo cy'icyuma gifite ishusho ya U gikoresha igishushanyo mbonera, gishobora kunoza imikorere y'ubwubatsi no kuzigama igihe n'amafaranga y'abakozi. Muri icyo gihe, bitewe n'imiterere yacyo yoroshye, gishobora gukatwa no gusudira hakurikijwe ibyo kubaka bikenewe, kandi gishobora guhinduka neza kandi kibereye ahantu hagoye hamwe n'ubwoko butandukanye bw'ubutaka n'ubutaka.
Byongeye kandi, imirundo y'icyuma ifite ishusho ya U irinda ibidukikije kandi ishobora kongera gukoreshwa. Ikozwe mu byuma byasubiwemo kandi bigira ingaruka nke ku bidukikije. Iyo imirimo yo kubaka irangiye, ibikoresho bya u type type sheet pile bishobora kongera gukoreshwa, bigabanura imyanda ituruka aho bubaka kandi bigahaza ibisabwa mu iterambere rirambye.
Birumvikana ko imigozi y'ibyuma yakoreshejwe cyane mu mishinga myinshi minini, nko mu mihanda y'amazi, aho baparika imodoka munsi y'ubutaka, ibiraro byo mu mazi, n'ibindi. Ntabwo binoza cyane imikorere n'ubwiza bw'inyubako z'umushinga gusa, ahubwo bishobora no guhaza neza ibisabwa mu mikoreshereze y'ubutaka mu mishinga yo kubaka imijyi.
Muri make, kugaragara k'urukuta rw'ibyuma byazanye amahitamo mashya mu ishami ry'ubwubatsi. Kubera ibyiza byarwo byo gukomera cyane, kwihuta mu bwubatsi, kurengera ibidukikije no kubungabunga ibidukikije, nta gushidikanya ko bizagira uruhare runini mu mishinga y'ubwubatsi y'ejo hazaza kandi bigire uruhare mu iterambere rirambye ry'umujyi.
Kugira ngo umenye byinshi ku bijyanye n'imirongo y'icyuma ifite ishusho ya U, nyamuneka hamagara itsinda ryacu ry'abahanga.
