Kugeza ubu umuyoboro munini w’Ubushinwa umuyoboro w’icyuma udafite icyuma, inzira nyamukuru y’umusaruro ni ugushyuha no kwagura ubushyuhe bw’imiyoboro nini ya diameter nini idafite icyuma, icyuma cyagutse gishyushye kidafite icyerekezo cya 325mm-1220mm gifite uburebure bwa 120mm, gishobora kubyara umuyoboro w’icyuma utagira umuyaga. Ibipimo bitari iby'igihugu, kwaguka k'ubushyuhe nta nkomyi nibyo dukunze kuvuga ko kwaguka k'ubushyuhe, ubucucike buri hasi cyane ariko gukomera gukomeye kuzunguruka ibyuma hakoreshejwe uburyo bwa oblique cyangwa uburyo bwo gushushanya kugirango habeho ikibazo cyo kubura imiyoboro ya diameter.Mugihe gito kugirango ibyuma byibyimbye bibyare umusaruro udasanzwe kandi wihariye wumuyoboro udafite kashe, hamwe nigiciro gito, umusaruro mwinshi, iterambere ryiterambere ryimirima mpuzamahanga muri iki gihe.
Umuyoboro munini wa diameter udafite icyuma ukoresheje gushushanya gukonje, ibicuruzwa bikonje bikonje, nko gukonjesha, kuvura ubushyuhe kandi nta na kimwe cyatanzwe na leta bita ubukonje cyangwa ubukonje.Ugereranije nuburyo bushyushye (guhimba) leta, uburebure buringaniye buringaniye ibyuma bikonje bikonje (bizunguruka), ubwiza bwubuso bwiza, ubutumburuke buke, hamwe nubukanishi buhanitse, bitewe nubukonje bwashushanijwe (buzunguruka) ibyuma bitanga okiside ni ntibipfundikirwa, kandi hariho imihangayiko myinshi, ishobora kwibasirwa na ruswa cyangwa ingese, bityo rero ibyuma bikonje bikonje (bizunguruka) leta, kubipakira, ibisabwa mububiko birakomeye, mubisanzwe bigomba kubikwa mububiko, kandi bigomba kwitondera isanduku yubushyuhe nubushuhe.
