    Ibirundo by'icyumabikozwe hifashishijwe ibikoresho byujuje ubuziranenge nubuhanga buhanitse, bigatuma byizewe cyane kumushinga wose wubwubatsi.Ibirundo bikunze gukoreshwa muri cofferdams kandi igishushanyo mbonera cyacyo cyubaka umutekano n'umutekano bisabwa kubishingwe nibindi bikorwa remezo.

    Iwacuumuyoboro munini wa diametersninkingi yibi byuma byicyuma, byongera kwizerwa no gukora.Binyuze mu gusudira neza no kugenzura ubuziranenge, turemeza ko buri kirundo cyujuje ubuziranenge bwo mu nganda.Iyi miyoboro itanga imiterere idasanzwe kandi iramba, ituma ibirundo byibyuma birwanya ibihe bikabije nibidukikije bikaze.

    Nkumushinga uyobora inganda, Cangzhou Spiral Steel Pipes Group Co., Ltd ifite ibikoresho bigezweho bifite ubuso bwa metero kare 350.000.Hamwe n'umutungo ungana na miliyoni 680 Yuan, dushora imari mu ikoranabuhanga rigezweho n'ibikoresho kugira ngo umusaruro ube mwiza.Byongeye kandi, abakozi bacu bitangiye abakozi 680 bareba ko ibicuruzwa byose bigenzurwa neza mbere yo kugera mumaboko yabakiriya bacu bafite agaciro.

    Umuyoboro wa SSAW

    Uruganda rwacu rufite umusaruro wa toni 400.000 yumuringa wibyuma bya spiral hamwe nagaciro kangana na miliyari 1.8.Iyi ntambwe yerekana ko twiyemeje gutanga serivise nziza no guhaza ibyo abakiriya bacu baha agaciro bakeneye ndetse no kwisi yose.

    Ibirundo by'icyumaihujwe na diameter nini yacu yasudutse itanga imiyoboro ihebuje, bigatuma ikwirakwira mugari.Usibye cofferdams, ibirundo byacu bikoreshwa cyane mukubaka ikiraro, ibikorwa remezo byicyambu nindi mishinga yinyanja.Igishushanyo cyihariye kigoramye cyangwa kizengurutse ibyo birundo bituma amazi meza hamwe nubutaka bwiza mugihe bitanga imiterere ikomeye.

    Isosiyete yacu yiyemeje ubuziranenge, ubunyamwuga no guhaza abakiriya bidutera guhora tunoza imikorere yinganda zacu no guteza imbere ibisubizo bishya.Twubahiriza amahame akomeye yo kugenzura ubuziranenge kugirango tumenye neza ko ibicuruzwa byacu bifite ubuziranenge kandi byujuje cyangwa birenze ibyo witeze.

    Muri make,ibyuma bya tubular ibirundobarimo guhindura inganda zubaka n'imbaraga nigihe kirekire cyumuyoboro munini wa diameter wasuditswe.Nubushobozi bwabo bwo guhangana nibibazo bitoroshye no gukoresha ubuhanga bwabo muri cofferdams, ibi birundo bitanga uburinzi ninkunga ntagereranywa.Umufatanyabikorwa hamwe na Cangzhou Spiral Steel Pipes Group Co., Ltd. kugirango ubone ibicuruzwa byiza-byongera imishinga yawe kandi bitanga ibisubizo birambye.
