Itanura rya tunnel nka bumwe mu buhanga bugezweho mu kubumba amatafari, bityo, niba ushaka kubaka uruganda rwamatafari, rwose ni amahitamo meza.
Ariko, nigute wakoresha itanura rya tunnel kugirango ucane amatafari?
Tuzaguha gusobanura birambuye.
Itanura rya tunnel ririmo itanura ryumye hamwe nitanura ryaka.
Ubwa mbere, Nyuma yimashini ishyiraho amatafari yimodoka yashizeho amatafari, imodoka ya klin yohereza amatafari kumatara yumye, kugirango yumishe amatafari. Kuma ubushyuhe bw'itanura ni 100 ℃. Kandi hari chimney ku itanura ryumye, ikoreshwa mugukuramo ubuhehere buva mu itanura ryumye.
Icya kabiri, amatafari nyuma yo gukama, koresha inzira imwe, koresha imodoka ya klin ohereza amatafari kumatara.
Itanura ryo gucana ririmo ibyiciro 4.
Icyiciro cya mbere: icyiciro cya preheat.
Icyiciro cya kabiri: icyiciro cyo kurasa.
Icyiciro cya gatatu: icyiciro cyo kubungabunga ubushyuhe.
Icyiciro cya kane: icyiciro cyo gukonjesha.
Noneho, niba ushaka kubaka itanura rya tunnel, turashobora gutanga ibipimo byumwuga byumwuga.
Amatara ya tunnel ibipimo fatizo:
| Mugari mu itanura (m) | Uburebure bw'itanura (m) | Ubushobozi bwa buri munsi (pcs) |
| 3.00-4.00 | 1.2-2.0 | 70.000 |
| 4.01-5.00 | 1.2-2.0 | , 000 100.000 |
| 5.01-7.00 | 1.2-2.0 | ≥150.000 |
| ＞ 7.00 | 1.2-2.0 | , 000 200.000 |
