    I-Diameter Enkulu Eshiselwe Amapayipi Izinqwaba ze-Tubular Zensimbi

    I-Diameter Enkulu Amapayipi Ashiselwe Amapayipi Ensimbi Ama-Tubular Piles Isithombe Esifakiwe
    • I-Diameter Enkulu Eshiselwe Amapayipi Izinqwaba ze-Tubular Zensimbi
    • I-Diameter Enkulu Eshiselwe Amapayipi Izinqwaba ze-Tubular Zensimbi

    Incazelo emfushane:

    Siyajabula ukwethula umkhiqizo wethu omusha wezinqwaba zamashubhu ensimbi, eziklanyelwe ukuhlinzeka ngokusebenziseka okuhle kakhulu kwezinhlelo zokusebenza ezihlukahlukene, ikakhulukazi ama-cofferdam.Lezi zinqwaba zifaka umklamo ogqagqene ogobile noma oyindilinga wamandla angenakuqhathaniswa nokuqina, ukuvala ngokuphumelelayo nokuvimbela ukungena kwamanzi, inhlabathi nesihlabathi.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Izinqwaba zamapayipi ensimbiakhiqizwa kusetshenziswa izinto ezisezingeni eliphezulu kakhulu kanye nobuchwepheshe obuphambili, okubenza buthembeke kakhulu kunoma iyiphi iphrojekthi yokwakha.Lezi zinqwaba zivame ukusetshenziswa kuma-cofferdams futhi ukwakheka kwazo okuqinile kwesakhiwo kuqinisekisa ukuphepha nokuzinza okudingekayo ezisekelweni neminye imisebenzi yengqalasizinda.

    Eyethuipayipi elikhulu elishiselwe ububanzisziwumgogodla walezi zinqwaba zamapayipi ensimbi, ezithuthukisa ukwethembeka nokusebenza kwazo.Ngokusebenzisa ukushisela okucophelelayo kanye nezinqubo zokulawula ikhwalithi, siqinisekisa ukuthi inqwaba ihlangabezana namazinga aphezulu embonini.Lawa mapayipi anikeza ukuguquguquka okukhethekile nokuqina, okuvumela izinqwaba zamapayipi ensimbi ukuthi zimelane nezimo ezimbi kakhulu kanye nezindawo ezinokhahlo.

    Njengomkhiqizi ohamba phambili embonini, iCangzhou Spiral Steel Pipes Group Co., Ltd. inezindawo ezisezingeni eliphezulu ezihlanganisa indawo engaphezu kwamamitha-skwele angu-350,000.Ngenani lempahla elifinyelela ku-680 million yuan, sitshala imali kubuchwepheshe obusezingeni eliphezulu namathuluzi ukuze siqinisekise ukukhiqizwa kwekhwalithi ephezulu kakhulu.Ngaphezu kwalokho, abasebenzi bethu abazinikele abangama-680 baqinisekisa ukuthi umkhiqizo ngamunye uhlolwa ikhwalithi eqinile ngaphambi kokuba ufinyelele ezandleni zamakhasimende ethu ayigugu.

    Ipayipi le-SSAW

    Ifektri yethu inomphumela waminyaka yonke wamathani angu-400,000 wamapayipi ensimbi avunguzayo kanye nenani eliphumayo lama-yuan ayizigidi eziyizinkulungwane ezingu-1.8.Lesi senzakalo esiyingqopha-mlando sibonisa ukuzibophezela kwethu ekuletheni isevisi esezingeni eliphezulu kanye nokuhlangabezana nezidingo zamakhasimende ethu ayigugu endaweni kanye nasemhlabeni jikelele.

    Izinqwaba zamapayipi ensimbikuhlanganiswe namapayipi wethu amakhulu ashiselwe ububanzi ahlinzeka ngokuguquguquka okuhle kakhulu, okuwenza afanelekele uhla olubanzi lwezicelo.Ngaphezu kwama-cofferdam, izinqwaba zethu zisetshenziswa kakhulu ekwakhiweni kwamabhuloho, ingqalasizinda yamachweba kanye neminye imiklamo yasolwandle.Idizayini eyingqayizivele egobile noma eyindilinga yalezi zinqwaba iqinisekisa ukugcinwa kwamanzi afanele kanye nenhlabathi kuyilapho inikeza uhlaka oluqinile lwesakhiwo.

    Ukuzibophezela kwenkampani yethu kukhwalithi, ubungcweti kanye nokwaneliseka kwamakhasimende kusishukumisela ukuba siqhubeke sithuthukisa izinqubo zethu zokukhiqiza nokuthuthukisa izixazululo ezintsha.Sithobela izindinganiso eziqinile zokulawula ikhwalithi ukuze siqinisekise ukuthi imikhiqizo yethu ingeyekhwalithi ephezulu futhi ihlangabezana noma idlule okulindele.

    Ngokufigqiwe,izinqwaba ze-tubular zensimbiziguqula imboni yezokwakha ngamandla nokuqina kwepayipi lethu elikhulu elishiselwe.Ngokukwazi kwazo ukumelana nezimo eziyinselele kanye nokusetshenziswa kwazo okukhethekile kuma-cofferdam, lezi zinqwaba zinikeza ukuvikeleka nokusekelwa okungenakuqhathaniswa.Uzakwethu ne-Cangzhou Spiral Steel Pipes Group Co., Ltd. ukuze uthole imikhiqizo yekhwalithi ephezulu ethuthukisa amaphrojekthi akho futhi ikunikeze izisombululo ezihlala isikhathi eside.
