Intangiriro y'ibicuruzwa

Tubagezaho imiyoboro yacu y'ibyuma byiza cyane yo kubaka, igamije kuzuza ibisabwa bikomeye mu bwubatsi bugezweho. Yakorewe mu ruganda rwacu rugezweho ruri i Cangzhou, mu Ntara ya Hebei, imiyoboro yacu y'ibyuma ikorwa hakoreshejwe ibikoresho byiza cyane n'ikoranabuhanga rigezweho. Kuva twashingwa mu 1993, twiyemeje kuba indashyikirwa kandi twabaye intangarugero mu nganda, dufite ubuso bwa metero kare 350.000 n'umutungo wose wa miliyoni 680 z'ama-ruble.

Imiyoboro yacu y'ibyuma yagenewe kuba yizewe kandi iramba, bigatuma iba myiza cyane mu bikorwa bitandukanye by'ubwubatsi nka cofferdams. Buri muyoboro unyura mu nzira ikomeye yo kugenzura ubuziranenge kugira ngo wujuje ibisabwa byo hejuru, biguha amahoro yo mu mutima ku mushinga wawe w'ubwubatsi. Dufite abakozi 680 b'abahanga, dushobora gukora imishinga y'ingano iyo ari yo yose, tugatanga umusaruro unyura gusa ku byo witeze, ariko kandi ukarenga ibyo usabwa.

Waba ukora ku mushinga munini w'ibikorwa remezo cyangwa umushinga muto w'ubwubatsi, imiyoboro yacu y'ibyuma byiza ni igisubizo cyiza ku byo ukeneye. Izere uburambe bwacu bw'imyaka myinshi n'ubwitange bwacu ku bwiza kugira ngo tuguhe ibikoresho byiza by'umushinga wawe w'ubwubatsi. Hitamo ibyacuikirundo cy'imiyoboro y'icyumakubera imbaraga zabyo, uburyo byizewe n'imikorere yabyo, kandi ukabona itandukaniro ibikoresho byiza bishobora kugira mu mushinga wawe w'ubwubatsi.

Akamaro k'ibicuruzwa

1. Imiyoboro y'ibyuma izwi cyane kubera ko ari myiza kandi ihamye, ni myiza cyane mu bikorwa bitandukanye by'ubwubatsi, nka cofferdams.

2. Imiterere yazo ikomeye ishimangira umutekano n'ituze bikenewe ku rufatiro n'ibindi bikorwa remezo.

3. Icyuma cyiza gikoreshwa mu gukora imiyoboro y'ibyuma gifasha kwihanganira imitwaro minini no kurwanya ibintu bihungabanya ibidukikije nko kwangirika no kugenda k'ubutaka.

4. Uburyo bwo gukora bukoreshwa n'amasosiyete nkacu, aherereye i Cangzhou, mu Ntara ya Hebei, butuma buri kirombe cyujuje ibisabwa mu buziranenge, bigatuma ba rwiyemezamirimo n'abahanga mu by'ubwubatsi batuza mu mutima.

Ibura ry'ibicuruzwa

1. Kimwe mu bibazo by'ingenzi ni ikiguzi; icyuma cyiza cyane kirahenze, ibyo bikaba bishobora gutuma ingengo y'imari y'umushinga yiyongera.

2. Uburyo bwo gushyiraho bushobora kugorana, busaba ibikoresho byihariye n'abakozi b'abahanga, ibyo bikaba bishobora kongera igihe cy'umushinga.

3. Nubwo imiyoboro y'ibyuma iramba, ishobora kwangirika mu buryo bumwe na bumwe iyo idafashwe cyangwa idafashwe neza.

Porogaramu

Mu isi y’ubwubatsi ihora ihinduka, guhitamo ibikoresho bigira ingaruka zikomeye ku ntsinzi no kuramba k’umushinga. Kimwe mu bikoresho byagaragaye ko ari ingenzi ni imiyoboro y’ibyuma byiza. Iyi miyoboro y’ibyuma ikorwa neza kandi ni ingenzi mu bikorwa bitandukanye by’ubwubatsi, cyane cyane mu gushyiraho umusingi ukomeye no kwemeza ko inyubako ikora neza.

Byakozwe hakoreshejwe ibikoresho byiza cyane n'ikoranabuhanga rigezweho,umuyoboro w'icyumaImigozi ni amahitamo yizewe ku mushinga uwo ari wo wose w’ubwubatsi. Imiterere yayo ikomeye y’inyubako ni ingirakamaro cyane cyane mu bikorwa nka cofferdams, aho ituze n’umutekano ari ingenzi cyane. Iyi migozi irashobora kwihanganira imitwaro iremereye n’ibidukikije bikomeye, bigatuma iba amahitamo meza y’abahanga n’abafatanyabikorwa.

Mu gusoza, gukoresha imiyoboro y'ibyuma byiza ni ingenzi kugira ngo umushinga w'ubwubatsi ugerweho. Kuba byizewe, bikomeye, ndetse n'uburyo bwo gukora ibintu bugezweho bituma biba byiza ku mishinga y'ishingiro n'ibikorwa remezo. Uko dukomeza guhanga udushya no kunoza ibicuruzwa byacu, dukomeje kwiyemeza gushyigikira inganda z'ubwubatsi dukoresheje ibikoresho byiza. Hitamo imiyoboro yacu y'ibyuma ku mushinga wawe utaha kandi wibonere itandukaniro mu bwiza n'imikorere.

Ibibazo Bikunze Kubazwa

Q1: Ibirundo by'imiyoboro y'icyuma ni iki?

Imiyoboro y'ibyuma ni inyubako zikozwe mu cyuma cyiza cyane, zigenewe kwinjizwa mu butaka kugira ngo zitange inkunga y'ishingiro. Zikorwa hakoreshejwe ikoranabuhanga rigezweho kugira ngo zigenzure ibisabwa bikomeye mu mishinga itandukanye y'ubwubatsi.

Q2: Kuki wahitamo imiyoboro y'ibyuma yo kubaka?

Imiyoboro y'ibyuma izwiho gukomera no kuramba kwayo. Imiterere yayo ikomeye ituma iba myiza cyane kuri cofferdams aho gutuza ari ingenzi cyane. Iyi miyoboro ishobora kwihanganira imitwaro iremereye n'ibidukikije bikomeye, bigatuma iba amahitamo yizewe yo gushingiraho n'indi mishinga y'ibikorwa remezo.

Q3: Kompanyi yawe iherereye he?

Isosiyete yacu yashinzwe mu 1993 ikaba iherereye mu Mujyi wa Cangzhou, mu Ntara ya Hebei. Ifite ubuso bwa metero kare 350.000, ifite umutungo wose wa miliyoni 680 z'amayuani, kandi ubu ifite abakozi 680. Twiyemeje gukora imiyoboro y'ibyuma byiza kandi ijyanye n'ibyo abakiriya bakeneye.

Q4: Ni izihe ngamba zo kugenzura ubuziranenge ufata?

Twibanda ku bwiza muri buri cyiciro cy'umusaruro. Imiyoboro yacu y'ibyuma ikorwa hakoreshejwe ibikoresho byiza cyane kandi ikoresha ikoranabuhanga rigezweho kugira ngo ihamye ko ari iy'ukuri. Uburyo bwacu bwo kugenzura ubuziranenge butuma ibicuruzwa byacu byujuje ibisabwa n'inganda ndetse n'ibisabwa n'abakiriya.

Ibanjirije iyi: Imiyoboro y'icyuma ikoreshwa mu nganda ikoreshwa mu byuma bitandukanye

Ibikurikira: Umuyoboro w'umuriro wizewe kugira ngo uhuze n'ibyo ukeneye mu mutekano

Andika ubutumwa bwawe hano hanyuma ubwoherereze
