Umuyoboro-Icyiciro Imiyoboro Yubatswe Kumurongo wa Gazi Kamere

Ibisobanuro bigufi:

Iyo wubaka imiyoboro ya gazi isanzwe, guhitamo ibikoresho nibyingenzi kugirango umutekano wibikorwa remezo bikorwe neza.Ibice byubatswe byubatswe, cyane cyane imiyoboro ya arc itwarwa na arc, bigenda byamamara kubera imbaraga zisumba izindi, kuramba no kurwanya ruswa.Muri iyi blog, tuzasesengura akamaro ka hollow-igice imiyoboro yubatswe mu iyubakwa ry'imiyoboro ya gazi yo munsi y'ubutaka nibyiza by'ingenzi batanga.

Imwe mu nyungu zingenzi zumuyoboro wubatswe wubusa ni uburyo bwiza bwo kurwanya ruswa.Iyo ushyinguwe mu nsi, imiyoboro ya gaze isanzwe ihura nubushuhe, imiti yubutaka nibindi bintu byangirika.Imiyoboro ya arc yarengewe na arc yagenewe cyane cyane guhangana niyi miterere mibi yubutaka, ikomeza kuramba no kwizerwa kwimiyoboro ya gaze karemano.

Usibye kurwanya ruswa,imiyoboro yubusatanga imbaraga zisumba iyindi kandi itajegajega, kugirango bikwiranye nubutaka bwubutaka.Igishushanyo mbonera cy'iyi miyoboro gitanga ubushobozi buhebuje bwo gutwara imitwaro, kibafasha kwihanganira uburemere bwubutaka nizindi mbaraga zo hanze bitabangamiye ubusugire bwimiterere.Ibi ni ingenzi cyane mubice bifite geologiya igoye, aho imiyoboro igomba kuba ishobora guhangana nubutaka no gutura.

Byongeye kandi, igice cyubusa imiyoboro yubatswe izwiho guhinduka no gukora neza.Ziza muburyo bunini bwubunini nubunini kandi zirashobora guhindurwa kugirango zuzuze ibisabwa byihariye byimishinga ya gazi isanzwe.Ibi na byo bigabanya gukenera ibikoresho byongeweho no gusudira, bikavamo kwishyiriraho byihuse no kugabanya ibiciro muri rusange.Imiterere yoroheje yiyi miyoboro nayo ituma ubwikorezi nogukora neza, bikagira uruhare mukuzigama.

Iyo bigeze kumutekano no gukora nezaimirongo ya gaze gasanzwe, guhitamo ibikoresho ni ngombwa.Umuyoboro wubatswe wubusa, cyane cyane imiyoboro ya arc yarengewe, ihuza imbaraga, iramba, irwanya ruswa hamwe nigiciro cyinshi, bigatuma iba nziza yohereza gaze gasanzwe.Mugushora imari mu miyoboro yo mu rwego rwo hejuru yagenewe cyane cyane ibikoresho byo munsi y'ubutaka, amasosiyete ya gaze arashobora kwemeza kwizerwa no kuramba kw'ibikorwa remezo mu gihe agabanya amafaranga yo kubungabunga no gusana mu gihe kirekire.

Muri make, imiyoboro yambukiranya ibice ifite uruhare runini mu iyubakwa rya gaze gasanzwe.Kurwanya ruswa iruta iyindi, imbaraga zisumba izindi hamwe nigiciro-cyiza bituma ihitamo bwa mbere mumishinga yo gutwara gaze gasanzwe.Muguhitamo ibikoresho bikwiye kubikoresho byubutaka, amasosiyete ya gazi karemano arashobora kubungabunga umutekano nubwizerwe bwibikorwa remezo byabo, amaherezo agafasha kugeza gazi karemano kubakoresha neza.
