Udukingirizo tw'umuhandaNi ibintu bisanzwe ku mihanda no ku mihanda minini hirya no hino ku isi. Abakozi bo mu mihanda, abubatsi na polisi bayikoresha mu kuyobora imodoka, gufunga ahantu no kuburira abashoferi ibyago bishobora kubaho. Ariko se wigeze wibaza uburyo imiyoboro y'imodoka ikorwa? Reka turebere hamwe.
Ibyuma bya mbere by’imodoka byari bikozwe muri sima, ariko byari biremereye kandi bigoye kubitwara. Mu myaka ya 1950, havumbuwe ubwoko bushya bwa terefone y’imodoka hakoreshejwe ibikoresho bya thermoplastic. Ibikoresho ni ibyoroheje, biraramba, kandi byoroshye kubibumba mu buryo butandukanye. Muri iki gihe, ibyuma byinshi by’imodoka biracyakozwe muri thermoplastic.
Uburyo bwo gukora icyuma gifata umuhanda gitangirana n'ibikoresho fatizo. Igikoresho gishongeshwa gishongeshwa n'amabara kugira ngo gihabwe ibara ry'umuhondo ryijimye risanzwe ku duce twinshi tw'icyuma. Hanyuma uruvange rusukwa mu bibumbano. Igibumbano gishushanyije nk'icyuma gifata umuhanda gifite hasi harambuye n'igice cyo hejuru.
Iyo uruvange rumaze gushyirwa mu ibumba, rurekurwa rugakonja kandi rugakomera. Ibi bishobora gufata amasaha menshi cyangwa ijoro ryose, bitewe n'ingano y'udusimba turimo gukorwa. Iyo udusimba tumaze gukonja, tukure mu ibumba hanyuma ucemo ibindi bintu byose bisigaye.
Intambwe ikurikiraho ni ukongeramo ibindi bintu kuri koni, nka kaseti igarura ubushyuhe cyangwa ishingiro rifite uburemere. Kaseti igarura ubushyuhe ni ingenzi cyane kugira ngo koni zigaragare nijoro cyangwa mu gihe cy'urumuri ruto. Ishingiro rifite uburemere rikoreshwa kugira ngo koni ikomeze ihagaze, ikarinda ko umuyaga uhuha cyangwa ngo igongwe n'ibinyabiziga binyuraho.
Amaherezo, utubuto tw’imodoka dupfunyikwa twoherezwa ku bacuruzi cyangwa ku bakiriya mu buryo butaziguye. Utubuto tw’imodoka zimwe na zimwe tugurishwa ukwatwo, izindi zikagurishwa mu matsinda cyangwa mu mapaki.
Nubwo inzira y'ibanze yo gukora koni y'imodoka ari imwe, hashobora kubaho impinduka zimwe na zimwe bitewe n'uwakoze. Bamwe mu bakora bashobora gukoresha ibikoresho bitandukanye, nka rabha cyangwa PVC, kuri koni zabo. Abandi bashobora gukora koni z'amabara cyangwa imiterere itandukanye, nk'ubururu cyangwa umuhondo byo guparika imodoka.
Uko ibikoresho cyangwa ibara ryakoreshejwe byaba biri kose, utudomo tw’umuhanda tugira uruhare runini mu kurinda abashoferi n’abakozi bo mu muhanda. Mu kuyobora ibinyabiziga no kumenyesha abashoferi ibyago bishobora kubaho, utudomo tw’umuhanda ni igikoresho cy’ingenzi mu kubungabunga umutekano wo mu muhanda.
Mu gusoza, uduce tw’imodoka dukoresha ikoranabuhanga ni ingenzi mu bikorwa remezo byacu byo gutwara abantu. Dukozwe mu bikoresho biramba kandi byoroheje kandi biboneka mu bunini butandukanye n’uburyo butandukanye. Waba utwaye imodoka mu gace k’ubwubatsi cyangwa ugenda ahantu hahurira abantu benshi, uduce tw’imodoka dukoresha ikoranabuhanga dushobora kugufasha kurinda umutekano. Noneho ko umaze kumenya uko dukorwa, uzishimira imiterere n’ubuhanga byakoreshejwe mu gukora ibi bikoresho by’ingenzi by’umutekano.
Niba ushishikajwe n'udukingirizo tw'umuhanda, ikaze kuvugana n'uruganda rwa Qixiang rukora udukingirizo tw'umuhanda kurisoma byinshi.
