Hamwe n'iterambere ryihuse ry'ubukungu bw'igihugu, inyubako zakunze kubaho cyane, hashyizweho isura nyinshi, kandi igoye, kandi ibikoresho n'imikorere yo guhora tuhangana, kandi ni ukuri kuri portal scafolding. Ariko, gutwarwa ninyungu zamasoko, ubucuruzi bwinshi bwakoze ubwiza bwimico kubwinyungu nyinshi.
Igicapo cya portal gifite ibiranga ibintu byoroshye kandi biterana, gukora imitwaro myiza yo kwikoreraza, hamwe nibikorwa byizewe kandi byizewe kandi byizewe kandi byizewe kandi byizewe. Byakoreshejwe cyane mu kubaka, mubyumba, ibiraro, vidoducts, tunels, ibibindi bikaba bitera inkunga byimbere, nibindi bikoresho byo kunyerera kugirango bishyigikire inyubako nyamukuru. Kubwibyo, ni ngombwa cyane cyane kwemeza ubwiza bwibicuruzwa bikoreshwa.
Ibicuruzwa bya portal byisi birimo: Amakadiri ya portal, amakadiri, igice cyamakaramu, inkoni ya diagonal hamwe na rods. Ubu bwoko bwibicuruzwa bivanze kandi bikoreshwa kugirango ugere ku burebure bw'ubwubatsi, kandi ubuziranenge bwemejwe. Ibikurikira byerekana ibyiza bya sisitemu yo gucamo ibice:
1. Ikadiri yumuryango ikozwe mubisobanuro bishyushye ibyuma yicyuma hamwe na diameter ya 42mm kugirango ibeho neza imbaraga zingufu kuri pole.
2.. Urugi rusunika Amepts CO2 Gurinda gusunika, ahantu hashya ntabwo byoroshye gukingirwa, kandi umutekano wubwubatsi wa sisitemu yumuryango byemewe.
3. Ubuso bwa bolt ni electro-galvanized kugirango hamenyekane neza hagati yinkoni ya diagonal na kamere nkuru.
4. Inkunga ya U-shusho yo hejuru ikozwe mu ruganda runini rw'ibyuma hamwe n'ubushobozi bukomeye bwo gutwara.
5. Inkoni ya diagonal ikozwe mu miyoboro ishyushye ibyuma yo kwisiga ibyuma kugirango iharanira umutekano wa mast.
6. Inziga zose zirashobora gutuma Mast yoroshye kwimuka mugihe cyo gukoresha.
7. Ishingiro rifite ubushobozi buhebuje hamwe nubuto bworoshye.
