Imiterere yubu ya H-Iterambere ryibyuma
Muburyo bugenda butera imbere bwubwubatsi bwikiraro, ihinduka rikomeye ririmo gukorwa hamwe no guhanga udushyaUmwirondoro wa H-beam. Ba injeniyeri nitsinda ryubwubatsi muruganda ubu barimo gukoresha imitungo idasanzwe yaH-beamimyirondoro, ihujwe nigishushanyo mbonera cyoroheje, kugirango izamure cyane ubushobozi bwo kwikorera imitwaro yikiraro - biranga ibihe bishya byimikorere, umutekano, kandi birambye mugutezimbere ibikorwa remezo.
Intangiriro nibyiza byicyuma cya H.
Umwirondoro wa H-beam, uzwiho gutandukanya "H" utandukanijwe, umaze igihe kinini uzwi kubikorwa byubukorikori buhanitse. Bitandukanyeimyirondoro gakondonka I-imirishyo, H-ibiti biranga parallel yo hejuru na hepfo ya flanges ihujwe nurubuga rwijimye, bivamo gukwirakwiza imbaraga zingana. Iyi nyungu yuburyo ituma H-beam irwanya kunama no guhindagurika neza, bigatuma ihitamo neza kubintu bitwara imitwaro mumishinga yikiraro. Ariko, ni uguhuza amahame yoroheje yo gushushanya yafunguye ubushobozi bwabo mumyaka yashize.
Dr. Elena Carter, inzobere mu by'ubwubatsi muri Global Infrastructure Innovations (GII), yasobanuye agira ati: “Mu myaka ibarirwa muri za mirongo, abashinzwe ikiraro bahuye n’ubucuruzi: kugira ngo twongere ubushobozi bwo gutwara imizigo, akenshi byabaye ngombwa ko twongera uburemere n’ubunini bw’ibyuma byakoreshwaga, byazamuye ibiciro by’ubwubatsi, byongerewe igihe cy’umushinga, kandi byongera ingufu ku nyubako zifatizo.” "Hamwe na H-beam imyirondoro hamwe n'ibishushanyo mbonera byoroheje, twahinduye ubwo bucuruzi. Mu guhindura ibipimo byambukiranya ibice bya H-beam - kugabanya ibikoresho bitari ngombwa mu bice bitari ngombwa mu gihe dushimangira uturere twinshi cyane - twashizeho imiterere yoroshye ariko ifite ubushobozi bwo gutwara imitwaro iremereye."
Ni izihe nyungu zo gushushanya byoroshye ibyuma bya H?
Umuyobozi w’umushinga wa Bridge River Crossing Bridge, Mark Torres yagize ati: "Igishushanyo mbonera cya H-beam ntabwo cyongereye ubushobozi bwo gutwara gusa; cyahinduye inzira zose zo kubaka." Ati: "Ibikoresho byoroheje byasobanuraga ko dushobora gukoresha ingendo ntoya, kugabanya umubare w'ingendo zo gutwara ibikoresho, no kwihutisha guteranira aho. Umushinga warangiye ibyumweru bitatu mbere y'igihe giteganijwe, kandi twazigamye amafaranga agera kuri miliyoni 1.5 y'amadorari yo kubaka. Ku baturage baho, bivuze ko mbere yo kubona inzira itwara abantu yizewe kandi yizewe."
Kurenga ikiguzi no kunguka neza, gukoresha udushya twa H-beam imyirondoro yubukorikori nabwo bugira uruhare mu ntego zirambye. Mu kugabanya ikoreshwa ry’ibyuma, imishinga nka Bridge River Crossing Bridge igabanya imyuka ihumanya ikirere ijyanye n’umusaruro w’ibyuma - ikintu cy’ingenzi mu bikorwa byo guhangana n’imihindagurikire y’ikirere. Byongeye kandi, igishushanyo cyoroheje kigabanya ingaruka z’ibidukikije ku mfatiro z’ikiraro, kubera ko hakenewe gucukurwa gake na beto kugira ngo bishyigikire imiterere, bigabanya ihungabana ry’ibinyabuzima byaho.
Iterambere ryizaza ryicyuma cya H.
Inzobere mu nganda ziteganya ko iyi nzira izakomeza kwiyongera kuko imishinga y’ibikorwa remezo ku isi ishyira imbere kwihangana no kuramba. Ishyirahamwe mpuzamahanga ry’ikiraro n’ubwubatsi (IABSE) riherutse gusohora raporo ivuga koH-beam imyirondoro ifite igishushanyo cyorohejebiteganijwe ko izakoreshwa muri 45% by'imishinga y'ikiraro giciriritse kugeza kinini muri 2028, aho yavuye kuri 15% gusa muri 2020.
Dr. Carter yongeyeho ati: "Ikiraro ni inkingi y’imiyoboro itwara abantu, kandi imikorere yazo igira ingaruka ku bukungu no mu buzima bwa buri munsi." Ati: "Gukoresha udushya twerekana imyirondoro ya H-beam ntabwo ari iterambere rya tekiniki gusa - ni igisubizo gikemura ibibazo byugarije inganda: umutekano, imikorere, ndetse no kuramba. Nidukomeza kunonosora uburyo bwo gukora ibishushanyo mbonera byoroheje ndetse tunateza imbere ibikoresho bikomeye bya H-beam, tuzashobora kubaka ibiraro bifite ubwenge, biramba, kandi bikwiranye n'ibikenewe mu bihe bizaza."
