Amakuru - Inkomoko yicyuma U gifite uruhare runini mubikorwa byubwubatsi

Icyuma U-ni ubwoko bwibyuma bifite igice cya U, mubisanzwe bikozwe nuburyo bushyushye cyangwa bukonje. Inkomoko yacyo irashobora guhera mu ntangiriro z'ikinyejana cya 20, hamwe n'iterambere ryihuse ry’inganda, icyifuzo cy'ibikoresho byo kubaka gikomeje kwiyongera,Icyuma Uni buhoro buhoro ikoreshwa cyane kubera imiterere yubukorikori nziza kandi itunganijwe neza. Ku ikubitiro, ibyuma U-bikoreshwa cyane cyane mumihanda ya gari ya moshi no mu nyubako zubaka, hamwe niterambere ryiterambere ryikoranabuhanga, umusaruro wabyo wagutse buhoro buhoro.

Icyuma U-gishobora gushyirwa mubice ukurikije ibipimo bitandukanye, harimo uburyo bwo gukora, gukoresha, ibikoresho, ingano no kuvura hejuru. Mbere ya byose, ukurikije inzira yumusaruro igabanijwemoashyushye-U-ibyumanicyuma gikonjesha U-cyuma, icyambere nimbaraga nyinshi, kibereye inyubako zikorera imitwaro, nkinyubako ndende na Bridges, mugihe iyanyuma yoroheje, ikwiranye nuburyo bworoshye kandi bukoreshwa muburyo bwo gushushanya. Icya kabiri, ukurikije ibikoresho,ibyuma bya karubone U-ibyumaikwiranye nubwubatsi rusange, mugihe ibyuma bitagira umuyonga U-bikwiranye nibidukikije bidasanzwe, nkinganda zitunganya imiti n’ibiribwa, kubera kurwanya ruswa. Gutandukanya ibyiciro bitandukanye byibyuma U bifasha guhaza ibikenewe mumirima itandukanye nkubwubatsi, ikiraro ninganda zimashini, byerekana uburyo butandukanye bwo gusaba.

Ibyuma U-bifite umwanya wingenzi mu nyubako zigezweho, cyane cyane bigaragarira mu mbaraga zayo zubaka kandi zihamye, ku buryo ishobora kwihanganira imitwaro iremereye kugira ngo inyubako itekane. Muri icyo gihe, igishushanyo mbonera cy’icyuma U kigabanya uburemere bw’inyubako, bityo bikagabanya ibiciro by’ishingiro n’imiterere y’ingoboka, no kuzamura ubukungu. Umusaruro wacyo usanzwe no koroshya ubwubatsi bitezimbere cyane ubwubatsi no kugabanya ibihe byumushinga, cyane cyane kubikorwa bisaba gutangwa vuba.

Muri rusange, umwanya wingenzi wibyuma U-shusho mubwubatsi bigaragarira mubikorwa byubaka, inyungu zubukungu, korohereza ubwubatsi no kubungabunga ibidukikije. Nka anibikoresho by'ingirakamaromubwubatsi bugezweho, ibyuma bya U-ntibitezimbere gusa umutekano nigihe kirekire cyinyubako, ahubwo binatanga amahirwe menshi yo gushushanya no kubaka, kandi biteza imbere iterambere no guhanga udushya mubikorwa byubwubatsi.
