Muri iki gihe, hamwe n’iterambere ry’ubukungu n’abaturage bakeneye ubwikorezi, Buri mujyi urimo kubaka metero imwe imwe,Urupapuro rw'icyumaigomba kuba ibikoresho byingenzi byubaka mugikorwa cyo kubaka metero.
Urupapuro rw'icyumaifite imbaraga nyinshi, ihuza cyane hagati yikirundo nikirundo, ingaruka nziza yo gutandukanya amazi, kandi irashobora gukoreshwa. Igice gisanzwe cyubwoko bwicyuma kirunda cyane U-cyangwa Z-shusho. Amabati y'ibyuma U akoreshwa mubwubatsi bwa gari ya moshi mu Bushinwa. Uburyo bwayo bwo kurohama no kuvanaho, gukoresha imashini ni kimwe nikirundo cya I-cyuma, ariko uburyo bwubwubatsi bwacyo bushobora kugabanywamo ibice byicyuma kimwe cya pile cofferdam, ibyuma bibiri byicyuma ikirundo cofferdam na ecran. Kubera umwobo wimbitse mugihe cyo kubaka gari ya moshi yo munsi, kugirango harebwe niba ihagaritse kandi yubake neza, kandi itume ishobora gufungwa no gufungwa, imiterere ya ecran ikoreshwa cyane.
Urupapuro rwicyuma cya Larsen uburebure bwa 12m, 15m, 18m, nibindi, umuyoboro wicyuma cyumuringa wikirundo cyuburebure bwa 6 ~ 9m, icyitegererezo nuburebure bigenwa no kubara. Ikirundo cy'icyuma gifite igihe kirekire. Nyuma yo kubaka urwobo rw'ifatizo rurangiye, ikirundo cy'icyuma kirashobora gukururwa no kongera gukoreshwa. Kubaka neza nigihe gito cyo kubaka; Ikirundo cy'ibyuma ntibishobora guhagarika amazi, mu gice cy’amazi maremare y’ubutaka, hagomba gufatwa ingamba zo kwigunga cyangwa kugwa. Umuyoboro wibyuma byumuyoboro ufite ubushobozi buke bwo kugunama, bikoreshwa cyane mubyobo fatizo cyangwa umwobo ufite ubujyakuzimu ≤4m, kandi gushyigikira cyangwa gukurura inanga bigomba gushyirwa hejuru. Inkunga yo gukomera ni nto kandi deformasiyo nyuma yo gucukura ni nini. Kubera ubushobozi bukomeye bwo kugonda, ikirundo cyicyuma cya Larsen gikoreshwa cyane mubyobo byimbitse 5m ~ 8m hamwe nibisabwa bidukikije, bitewe nubufasha (gukurura inanga).
