Ibyatsi bibi n'ibihuru ni ahantu habi murwego rwo guhitamo urubuga rwa tunnene. Mugihe cyubushakashatsi bwikirere, ibintu bireba umutekano rusange wumurongo ntibigomba kugaragara no kubaho. Guhitamo inkunga ya tunnel nabyo ni umwihariko, kandi hariho n'amahame amwe akeneye kwishyurwa mu bikorwa byo kubaka.
Hariho ingingo nyinshi zo kwitondera mugihe usudira umuyoboro wa tunnel ibyuma:
1. Mu bidukikije bifunguye, inkunga isukuye isudira irashobora kubaka isuka mugihe. Witondere kutabona imvura na shelegi kurubuga.
2. Mu gihe cy'itumba gikonje, niba isahani y'icyuma irenze 9mm, irashobora gusudikurwa mubice byinshi. Ibi ni ukubuza ubushyuhe bwo hasi cyane, ariko muri rusange, gusudira bigomba kuzuzwa icyarimwe kandi ubudahwema. Iyo usudigure, inenge zasizwe no gusudira zigomba gukosorwa mbere, kandi gusudira birashobora gukomeza nyuma yuko ntakibazo.
3. Mu bushyuhe buke buke, electrode n'insinga zikoreshwa mu gusudira ibyuma bigomba kuba amatora make afite imbaraga hamwe n'imbaraga nyinshi mu bihe bisanzwe.
4. Inkoni zo gusudira zikoreshwa mugusumura munsi ya zeru zeru zigomba kuba zifite ibipimo bisanzwe, bigomba gushyirwa mumasanduku yo guteka ya selisiyusi ya 80 kugeza 100, kandi ikoreshwa mugihe bikenewe. Niba electrode yashyizwe munsi ya zeru amasaha arenga abiri, igomba kongera gutekwa, ariko inshuro zigomba kuba munsi yinshuro eshatu.
