Ubwoko bwo kumanuka busobanura ko icyerekezo gitemba cyumuyaga ushyushye ni kimwe nicy'ibikoresho, byombi biva kumpera y'ibiryo bigana ku musozo. Iyo ibikoresho byinjiye mu ngoma gusa, imbaraga zo gutwara ni nini kandi amazi yubusa ni menshi. Umuvuduko wo kumisha igice cyimbere cyubwoko butemba nicyo cyihuta cyane, hanyuma mugihe ibintu byimukiye ku cyambu gisohoka, ubushyuhe bwibintu bwiyongera, imbaraga zo gutwara zumuke ziba nto, ibinyabuzima byubusa bigabanuka, kandi umuvuduko wo gukama nayo itinda. Kubwibyo, kumisha ingoma yamanutse-yumisha ntago iringaniye kuruta ubwoko bwa contre-flow.

Ubwoko bwa contre-flow ni uko icyerekezo cyogutemba cyumuyaga ushyushye kinyuranye nicyerekezo cyerekezo cyibintu, kandi ubushyuhe bwingoma nuburebure hejuru yibintu bisohoka, kandi ubushyuhe buri munsi yibintu byinjira . Ubushyuhe bwibikoresho ni buke cyane iyo bwinjiye bwa mbere ingoma, kandi ubushyuhe ni bwo hejuru cyane ku musozo wo gusohoka, buri mu cyerekezo kimwe n'ubushyuhe bwo hejuru n'ubushyuhe buke bw'ingoma. Kuberako ubushyuhe bwo hejuru bwingoma buri kuruhande rumwe nubushyuhe bwo hejuru bwibintu, kandi ubushyuhe bwo hasi bwingoma buri kuruhande rumwe nubushyuhe bwo hasi bwibikoresho, bityo imbaraga zo gutwara zumye zihurira hamwe ni nyinshi kuruta ibyo kumanuka kumanuka.

Muri rusange, gushyushya ingoma bikorwa ahanini nubushyuhe. Ubwoko bwo kumanuka busobanura ko icyumba cyo gutwika hamwe n ibiryo byinjira byashyizwe kuruhande rumwe, kandi icyerekezo cyogutemba cyumuyaga ushyushye nikintu kimwe nikintu. Bitabaye ibyo, ni ubwoko bwa contre-flow.

Iyo ingoma ya anti-flux yumye kandi igashyuha, imbere yingoma yumye irashobora kugabanywamo ibice bitatu ukurikije ihindagurika ryubushyuhe bwibintu: ahantu hahumeka, ahantu humye no gushyushya. Kuberako ibikoresho birimo ubuhehere iyo bwinjiye bwa mbere ingoma, ubuhehere bwibikoresho buzakurwa muri zone ya mbere, igiteranyo kizumishwa muri zone ya kabiri, kandi ingoma izaba iri ku bushyuhe bwinshi muri zone ya gatatu Twandikire ibikoresho byumye kugirango ubushyuhe buzamuke. Muri rusange, uko ubushyuhe bwibintu bwiyongera mungoma ya contre-current, uburyo bwo kumisha nabwo buriyongera, bityo imbaraga zo kumisha zikaba zisa, itandukaniro ryubushyuhe buri hagati yumuyaga ushyushye nibikoresho ni binini, kandi nubushobozi bwa gukama-konte yumye biroroshye. gutemba hejuru.

Kuriingoma yo mu bwoko bwa asfalt ivanga igihingwa, ingoma ifite imirimo ibiri, gukama no kuvanga; Mugihe Kuriicyiciro cyo kuvanga asfaltnaguhoraho kuvanga asfalt, ingoma ikina gusa uruhare rwo gushyushya. Kuberako kuvanga mubice hamwe no gukomeza kuvanga asfalt bihingwa bikorwa binyuze mu nkono ivanze, nta mpamvu yo kongeramo asfalt ku ngoma yo kuvanga, bityo ingoma yumye ihura nigihe cyo gukama cyane ikoreshwa.
