Guhinduranya Amazi Yubutaka hamwe no gusudira ibyuma
Hagati ya Cangzhou, Intara ya Hebei, isosiyete yagiye itera imbere byihuse murigusudira ibyumainganda kuva yashingwa mu 1993. Ifite metero kare 350.000, ifite umutungo wa miliyoni 680 z'amafaranga y'u Rwanda hamwe n'abakozi babigize umwuga bangana na 680, ubwitange mu bijyanye no guhanga udushya no guhanga udushya byayishyizeho nk'umuyobozi mu gukora ibisubizo bigezweho by’imiyoboro, cyane cyane kuri sisitemu y'amazi yo mu kuzimu.
Kimwe mu bicuruzwa byabo bihagaze neza ni umuyoboro wa polypropilene uhinduranya umurongo, ushyiraho urwego rushya rwo kuramba no kwizerwa muri sisitemu yo gutanga amazi yo munsi. Uyu muyoboro udasanzwe urenze ibicuruzwa gusa; byerekana gusimbuka cyane muburyo bwa tekinoroji yo gusudira. Isosiyete ikoresha tekinoroji igezweho yo gusudira arc gusudira kugirango buri muyoboro ukorwe neza kugirango uhangane n’ibikorwa byo gushyira mu nsi.
Imirongo ya polypropilene ihindura sisitemu yubutaka. Itanga urwego rwinyongera rwo kwirinda ruswa no kwangirika, ibibazo bisanzwe hamwe nimiyoboro gakondo. Uru rutonde ntirwongerera ubuzima gusa umuyoboro ahubwo runemeza ko amazi akomeza kuba umwanda, bityo bikaba amahitamo meza kubisabwa kuva muri sisitemu y’amazi ya komine kugeza kuhira imyaka.
Iyi sosiyete yitwaye neza mu marushanwa yo gusudira ibyuma kubera ubwitange budacogora ku bwiza. Intambwe yose yuburyo bwo gukora irakurikiranwa cyane kugirango yujuje ubuziranenge. Ubwitange bwabo mu guhanga udushya bugaragara mugukoresha tekinoroji ya arc welding tekinoroji. Ubu buryo ntabwo bwongera imbaraga zo gusudira gusa ahubwo bunazamura uburinganire bwimiterere rusange yumuyoboro, bigatuma bukoreshwa muburyo bwumuvuduko mwinshi.
Byongeye kandi, ubunararibonye bwikigo bwinganda bubafasha kumva ibibazo byihariye abakiriya babo bahura nabyo. Bakorana cyane nabakiriya kugirango batange ibisubizo byabigenewe byujuje ibyifuzo byihariye, bareba intsinzi ya buri mushinga. Yaba umushinga munini wa komini cyangwa umushinga muto wubuhinzi, itsinda ryinzobere ryama ryiteguye gufasha abakiriya guhitamo ibicuruzwa byiza no gutanga inkunga ikenewe mugihe cyo kwishyiriraho.
Mugihe icyifuzo cya sisitemu yo mumazi yizewe ikomeje kwiyongera, akamaro k'ibisubizo byujuje ubuziranenge ntibishobora gusuzugurwa. Imiyoboro ya polypropilene yakozwe n'iyi sosiyete ikorera mu mujyi wa Cangzhou ntabwo ari ibicuruzwa gusa; bagaragaza kwiyemeza ubuziranenge, kuramba, no kwizerwa. Hamwe nikoranabuhanga ryabo ryambere ryo gusudira ibyuma, barimo gutegura inzira ya sisitemu yo gutanga amazi ejo hazaza idakora neza ariko kandi irambye.
Muri make, ikoranabuhanga rishya, kwiyemeza ubuziranenge, no gusobanukirwa byimazeyo ibyo abakiriya bakeneye byatumye isosiyete iba umuyobozi mubikorwa byo gusudira ibyuma. Imiyoboro yabo ya polypropilene yerekana ubwitange bwabo mugutanga ibisubizo byiza kuri sisitemu yubutaka. Mugihe bakomeje gusunika imbibi zogukora imiyoboro, ikintu kimwe kirasobanutse: ejo hazaza h’amazi yo mu butaka ari mumaboko yizewe.
