Mubisanzwe, twita imiyoboro isudira urutoki rufite diameter yo hanze irenga 500mm cyangwa irenga nka diameter nini ya diametre igororotse. Imiyoboro minini ya diametre igororotse nicyuma cyiza nicyiza cyiza kumishinga minini yimiyoboro, imishinga yohereza amazi na gaze, hamwe no kubaka imiyoboro yumujyi. Mu yandi magambo, imiyoboro minini ya diametre igororotse-ifite ibyuma binini bifite umurambararo munini kandi ntarengwa (umurambararo ntarengwa w’imiyoboro y’icyuma idafite icyuma ni 1020mm, umurambararo ntarengwa w’imiyoboro y'ibyuma ushobora gusudira kabiri ushobora kugera kuri 2020mm, kandi umurambararo ntarengwa w’imyenda imwe ushobora kugera kuri 1420mm), inzira yoroshye nigiciro gito. nibindi byiza bikoreshwa cyane.
Impande ebyiri zashizwemo arc zasudutse neza ibyuma byicyuma nabyo ni imiyoboro igororotse. Umuyoboro wamazi wamazi washyizwemo icyuma kigizwe nicyuma cya JCOE gikonje, icyuma cyo gusudira gifata insinga yo gusudira, naho gusudira arc kurengerwa bigatwara uduce duto duto. Igikorwa nyamukuru cyo gukora arc yarengewe nuyoboro wicyuma cyoroshye cyoroshye, kandi gishobora gutanga ibisobanuro ibyo aribyo byose, byujuje ahanini ibisabwa n’amahanga ku bunini bw’icyuma, mu gihe umusaruro usanzwe wo mu gihugu usanzwe ukoresha umuyoboro mwinshi w’icyuma.
Hamwe niterambere ryubukungu bwigihugu, icyifuzo cyingufu cyiyongereye cyane. Mu myaka icumi iri imbere cyangwa imyaka mirongo iri imbere, ni ngombwa guteza imbere ikoranabuhanga no kubaka umushinga.
