    Diameter nini yasuye imiyoboro ya pirisi

    Diameter nini yasuye imiyoboro ya steel ibituba byerekana ishusho
    • Diameter nini yasuye imiyoboro ya pirisi
    • Diameter nini yasuye imiyoboro ya pirisi

    Ibisobanuro bigufi:

    Tunejejwe no gushyiramo uduce twinshi twinshi ibirundo, byateguwe kugirango tutange ibintu byiza kubintu bitandukanye, cyane cyane coffersams. Ibi birundo biranga umurongo ugoramye cyangwa uzengurutse kumbaraga zidahera no kuramba, gufunga neza no kubuza inshinge y'amazi, ubutaka n'umucanga.

    IbyacuDiameter nini yarasuyesni umugongo w'ibi birundo by'icyuma, bikangezwa kwizerwa no gukora. Binyuze mu gusudira no kugenzura ubuziranenge, twemeza ko buri kirundo cyujuje ubuziranenge bwo hejuru. Iyi miyoboro itanga guhinduka bidasanzwe no kuramba, kwemerera ibirundo by'icyuma kugirango bihangane ibintu bikabije nibidukikije bikaze.

    Nk'uko uruganda rukora inganda, kanseri ya cangzhou spiral ibyuma co., Ltd. ifite ibikoresho-byubuhanzi bikubiyemo ubuso bwa metero kare 350.000. Hamwe n'agaciro ka miliyoni 680 ya Yuan, dushora imari mu guca ikoranabuhanga n'ibikoresho kugira ngo umusaruro mwiza. Byongeye kandi, abakozi bacu bitanze bakozi bakozi 680 babyemeza ko ibicuruzwa byose bihunze cheque nziza mbere yo kugera kumaboko yabakiriya bacu bafite agaciro.

    Umuyoboro wa Ssaw

    Uruganda rwacu rufite umusaruro wa buri mwaka wa toni 400.000 ya stiel ibyuma hamwe nibisohoka bya miliyari 1.8 yuan. Iyi ntambwe yerekana ko twiyemeje gutanga indashyikirwa mu murimo no guhaza ibyo abakiriya bacu baha agaciro gahamye kandi ku isi.

    Amashanyaraziguhuzwa na diameter yacu yasuye itanga ibisobanuro byiza, bigatuma bikwiranye nuburyo butandukanye. Usibye Cofferdams, ibirundo byacu bikoreshwa cyane mu kubaka ikiraro, ibikorwa remezo by'ibikorwa remezo n'indi mishinga yo mu nyanja. Igishushanyo mbonera cyihariye cyangwa cyuzuye cyibipurusi cyemeza amazi meza no kugumana ubutaka mugihe utanga imiterere ikomeye.

    Isosiyete yacu yiyemeje ubuziranenge, umwuga no kunyurwa kwabakiriya bidutera guhora dukora neza gahunda zacu zo gukora no guteza imbere ibisubizo bishya. Turakurikiza amahame yo kugenzura ubuziranenge kugirango ibicuruzwa byacu bifite ubuziranenge kandi buhure cyangwa burenze ibyo witeze.

    Muri make,Ibirundoni uguhindura inganda zubwubatsi hamwe nimbaraga nubwara byimiyoboro minini ya diamet. Hamwe n'ubushobozi bwabo bwo guhangana n'ibisabwa bitoroshye hamwe no gukoresha neza muri Cofferdams, ibi birundo bitanga uburinzi n'inkunga. Umufatanyabikorwa hamwe na Cangzhou spiral ibyuma bya Stipel Co., Ltd. Kubona ibicuruzwa byiza byongera imishinga yawe kandi bigatanga ibisubizo birambye.
