Ibyiza bya sosiyete

Uruganda rwacu ruherereye i Cangzhou, mu Ntara ya Hebei, kandi twabaye ku isonga mu gukora imiyoboro y’ibyuma yo mu rwego rwo hejuru kuva twashingwa mu 1993. Uruganda rwacu rufite ubuso bwa metero kare 350.000, umutungo wose w’amafaranga miliyoni 680, rushobora gutanga toni 400.000 z’imiyoboro y’icyuma ku mwaka, kandi ifite abahanga 680 babishoboye.

Kumenyekanisha ibicuruzwa

Ubwitange bwacu bwo kuba indashyikirwa bugaragarira mubikorwa byacu byo gusudira arc byitondewe, iyi ikaba ari intambwe ikomeye mu gukora imiyoboro yacu isudira. Iri koranabuhanga rikoresha ubushyuhe bwo hejuru kugirango ribe umurongo ukomeye kandi urambye hagati yimiyoboro, ukemeza ko ibicuruzwa byacu bitanga imikorere yizewe ndetse no mubidukikije bigoye. Waba uri mu nganda za gaze karemano cyangwa ukeneye ibisubizo byizewe kubindi bisabwa, imiyoboro yacu izuzuza kandi irenze ibyo wari witeze.

Hamwe no kwibanda ku bwiza no guhanga udushya, twishimiye gutanga imiyoboro yo gusudira yemeza imikorere irambye. Ntabwo ari abacu gusaumuyoboro wizungurukaikomeye kandi iramba, nayo irakora neza cyane, bigatuma iba nziza kumishinga isaba kwizerwa no kuramba.

Ikintu nyamukuru

Kimwe mu bintu by'ingenzi biranga gusudira mu miyoboro ni ukwishingikiriza ku gusudira arc, tekinike ikoresha ubushyuhe bwinshi kugira ngo habeho amasano akomeye, arambye hagati y'ibyuma. Inzira ningirakamaro kugirango habeho ubusugire n’ubwizerwe bwibicuruzwa byanyuma, cyane cyane mubisabwa aho umutekano n’imikorere ari ngombwa, nko gutwara gaze gasanzwe.

Igikorwa cyo gusudira arc kirimo gushonga impande zumuyoboro no kuzihuza hamwe, gukora ihuza ridasubirwaho rishobora kwihanganira umuvuduko mwinshi nibihe bikabije. Ubu buryo ntabwo bwongera imbaraga z'umuyoboro gusa, ahubwo bunagura ubuzima bwa serivisi, bigatuma uhitamo guhitamo mubikorwa bitandukanye byinganda.

Byongeye kandi, ubuhanga nubuhanga bukenewe mu gusudira imiyoboro yerekana kandi isosiyete yiyemeje ubuziranenge. Mu gushora imari mu ikoranabuhanga ryateye imbere hamwe n’abakozi bafite ubumenyi, uruganda rwa Cangzhou rwemeza ko buri muyoboro usudira uzunguruka wujuje ubuziranenge bw’inganda, bigaha abakiriya amahoro yo mu mutima no kwizera ibicuruzwa.

Ibyiza byibicuruzwa

Kimwe mu byiza byingenzi byo gusudira imiyoboro nubushobozi bwayo bwo kubyara ingingo zikomeye zishobora kwihanganira umuvuduko mwinshi hamwe nikirere gikabije. Ibi ni ingenzi cyane mu nganda za gaze karemano, aho ubusugire bwumuyoboro ari ingenzi. Inzira yo gusudira arc yemeza kotube weldntabwo ikomeye gusa ahubwo irahoraho, igabanya ibyago byo kumeneka no gutsindwa. Byongeye kandi, imikorere yo gusudira iti ituma abayikora bakora vuba vuba imiyoboro myinshi yicyuma kizenguruka kugirango isoko ryiyongere.

Ibura ry'ibicuruzwa

Inzira isaba abakozi babahanga no kugenzura neza ibipimo byo gusudira kugirango birinde inenge nko gutitira cyangwa kubura fusion. Ibi bibazo birashobora guhungabanya ubuziranenge bwibicuruzwa byanyuma kandi biganisha ku guhungabanya umutekano.

Byongeye kandi, ubushyuhe bwo hejuru bwo gusudira arc burashobora kuzana imihangayiko isigaye mubikoresho, bishobora kugira ingaruka kumikorere ndende.

Ibibazo

Q1: Gusudira arc ni iki?

Gusudira Arc ni tekinike ikoresha ubushyuhe bwinshi butangwa na arc y'amashanyarazi gushonga no guhuza amabati hamwe. Ku miyoboro isudira izunguruka, ubu buryo ni ngombwa kugirango habeho guhuza gukomeye hagati yimiyoboro, ifite akamaro kanini mumikorere nubuzima bwumuyoboro.

Q2: Kuki gusudira arc ari ingenzi kumiyoboro ya gaze gasanzwe?

Imiyoboro ya gazi isanzwe igomba kuba yujuje ubuziranenge bwumutekano no kwizerwa. Igikorwa cyo gusudira arc cyemeza ko ingingo zo gusudira zishobora guhangana n’umuvuduko mwinshi kandi zikarwanya ruswa, bigatuma biba byiza gutwara gaze karemano intera ndende.

Q3: Isosiyete yawe iherereye he?

Uruganda rwacu ruherereye i Cangzhou, Intara ya Hebei, agace kazwiho ingufu mu nganda. Isosiyete yacu yashinzwe mu 1993 kandi yakuze cyane ku buso bwa metero kare 350.000 kandi ikoresha abakozi 680 bitanze.

Q4: Ubushobozi bwawe bwo gukora ni ubuhe?

Twishimiye gutanga toni 400.000 z'umuyoboro w'icyuma uzunguruka ku mwaka. Umubare munini wumusaruro ni gihamya ko twiyemeje ubuziranenge no gukora neza mubikorwa byacu byo gukora.
