Kumenyekanisha urupapuro rwibyuma cya Larsen

NikiUrupapuro rwa Larsen?
Mu 1902, injeniyeri w'Ubudage witwa Larse wa mbere yabyaye ubwoko bw'ibyuma by'icyuma hamwe na wambukiranya kandi ugabanijwe ku mpande zombi, kandi byiswe "Urupapuro rwa larsen"Nyuma yizina rye. Muri iki gihe, ibirundo by'icyuma bya larse byamenyeshejwe ku isi kandi bikoreshwa cyane mu myobope y'imyobo y'isi

Urupapuro rwa Larsen rwibyuma ni urwego mpuzamahanga rusanzwe, ubwoko bumwe bwurupapuro rwa Lassen yicyuma cyakozwe mubihugu bitandukanye birashobora kuvangwa mumushinga umwe. Igipimo cyibicuruzwa byibirundo bya Larsen byasohoye ingingo nibisabwa mubunini bwimiterere, gufunga imiti, imitungo nubufatanye nibipimo byibikoresho, kandi ibicuruzwa bigomba kugenzurwa rwose nuruganda. Kubwibyo, urutoki rw'ibyuma rwa Larse rufite ibyiringiro byiza hamwe nimico myiza, kandi irashobora gukoreshwa inshuro nyinshi nkibikoresho byo kuvugurura, bifite inyungu zidasanzwe muguhaza ikiguzi cyubwubatsi no kugabanya ikiguzi cyumushinga.

 

Ubwoko bwa pari ya Larsen

Dukurikije ubugari butandukanye bw'igice, uburebure n'ubugari, ibirungo by'icyuma bya larsen birashobora kugabanywamo moderi zitandukanye, kandi ubugari bwiza bwikirundo kimwe cyakoreshejwe cyane cyane ibirungo byakoreshejwe ahanini, ni ukuvuga 400mm na 600mm.
Uburebure bwa page yicyuma cya Tensile irashobora gutangwa no gukorwa hakurikijwe umushinga ukeneye, cyangwa birashobora gucamo ibirundo bigufi cyangwa gusudira binini binini nyuma yo kugura. Iyo bidashoboka gutwara ibirundo kirekire ku rubingo rw'ibyuma kubera aho bigarukira ku modoka n'imihanda, ibirundo by'ubwoko bumwe birashobora gutwarwa ahazubakwa hanyuma bisusuruke.
Urupapuro rwa Larsen
Dukurikije imbaraga zitanga ibikoresho, amanota yibikoresho byimiterere yicyuma bihuye nibisanzwe ni Q295p, Q465P, Q460P, nibindi., Nibindi bihuye nibipimo byabayapani niSy295, Sy390, nibindi byinshi Ibikoresho, usibye ibihimbano byabo, birashobora kandi gusudira no kurambura. Ibyiciro bitandukanye byibikoresho hiyongereyeho imiti itandukanye, ibipimo bya mashini nabyo biratandukanye.
