Amakuru arambuye
Dukurikije ifu y’icunga igabanyijemo icyuma, icunga rikomeye ridashobora kwangirika ry’icyuma, rigizwe n’uduce runaka tw’icunga rigizwe n’amabuye y’agaciro cyangwa icunga ridafite feri ridashobora kwangirika cyane hamwe n’inyongera zidasanzwe. Icunga rigizwe n’imiterere yaryo, icyiciro cyaryo n’imiterere yaryo myiza cyane.

Ingano y'ikoreshwa
Ikoreshwa mu nganda, mu bubiko, mu maduka manini, mu nganda zikora imashini zikomeye, mu parikingi z'imodoka, mu bice byo gupakira imizigo, mu bikari no mu zindi nyubako.
Ibiranga imikorere
Ikwirakwizwa ku buso bwa sima mu ntangiriro yo gukonja, kandi nyuma yo gukonja muri rusange, ikora urwego rw'ubuso rukomeye kandi rukomeye cyane hamwe n'ubutaka bwa sima, burwanya igitutu, burwanya ingaruka, burwanya kwangirika kandi bufite ubwiza n'amabara meza nk'ubutaka burwanya kwangirika. Ishobora kubakwa hamwe n'ubutaka bwa sima, ikagabanya igihe cyo gukora, kandi nta mpamvu yo kubaka urwego rwo kunganya na sima.
Ibiranga sisitemu
Kubaka byoroshye, gukwirakwizwa neza kuri sima nshya, kuzigama umwanya n'akazi, nta mpamvu yo kubaka urwego rwo kugabanya sima; kudatera kwangirika cyane, kugabanya ivumbi, kongera ubudahangarwa bw'ingaruka, kongera ubudahangarwa bw'amavuta n'amavuta.
Uburyo bwo kubaka
◇ Gutunganya ubuso bwa sima: koresha icyuma gikoresha icyuma gishyushya amazi gifite disiki kugira ngo ukureho neza urwego rw'amazi areremba ku buso bwa sima;
◇Ibikoresho byo gukwirakwiza: shyira 2/3 by'ingano yagenwe y'ibikoresho bikomeye byo hasi bidashira ku buryo bungana ku buso bwa sima mu ntangiriro yo kuyishyiraho, hanyuma uyisukure ukoresheje imashini yoroshye yoroshye;
◇Gupima ibikoresho bikomeye bidashira: gukata no kugabanya ibikoresho bikomeye bidashira neza mu cyerekezo cyambukiranya n'icya kure ukoresheje icyuma cya metero 6 gipima;
◇Gukwirakwiza ibikoresho byinshi: shyira ku rugero rumwe 1/3 cy'ingano yagenwe y'ibikoresho bikomeye birwanya ibara (ku buso bw'ibikoresho birwanya ibara byamaze igihe kinini bisukurwa), hanyuma wongere uhanagure ubuso ukoresheje imashini itunganya;
◇ Gusukura ubuso: ukurikije uko beto ikomera, hindura inguni y'icyuma ku mashini isukura, hanyuma uhanagure ubuso kugira ngo ubuso bube burumbaraye kandi bunoze;
◇ Kubungabunga no kwagura ubuso bw'ibanze: hasi ikomeye idashaje igomba kuguma ku butaka mu masaha 4 kugeza kuri 6 nyuma y'uko imirimo yo kubaka irangiye, kugira ngo hirindwe ko amazi ashobora guhumeka vuba ku buso, kandi habeho ukwiyongera guhamye kw'imbaraga z'ibikoresho bidashaje.
