    Incazelo emfushane:

    Siyajabula ukwethula imikhiqizo yethu emisha yezinsimbi ezigobile, ezenzelwe ukuhlinzeka ngokusebenziseka okuhle kakhulu kwezinhlelo zokusebenza ezahlukahlukene, ikakhulukazi ama-cofferdams. Lezi zinqwaba zinomklamo ogobile noma ojikelezayo ohambisanayo ukuze kube namandla nokuqina okungenakuqhathaniswa, ovala ngempumelelo futhi uvimbele ukungena kwamanzi, inhlabathi kanye nesihlabathi.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Izinqwaba zamapayipi ensimbiakhiqizwa kusetshenziswa izinto ezisezingeni eliphezulu kanye nobuchwepheshe obuthuthukisiwe, okwenza athembeke kakhulu kunoma yimuphi umsebenzi wokwakha. Lawa ma-pile avame ukusetshenziswa e-cofferdams futhi ukwakheka kwawo okuqinile kuqinisekisa ukuphepha nokuzinza okudingekayo ezisekelweni kanye neminye imisebenzi yengqalasizinda.

    Okwethuipayipi elihlanganisiwe elinobubanzi obukhulusziyinsika yalezi zinqwaba zamapayipi ensimbi, okuthuthukisa ukuthembeka nokusebenza kwazo. Ngokusebenzisa ukushisela okucophelelayo kanye nezinqubo zokulawula ikhwalithi, siqinisekisa ukuthi inqwaba ngayinye ihlangabezana nezindinganiso eziphakeme kakhulu embonini. Lawa mapayipi anikeza ukuguquguquka okumangalisayo nokuqina, okuvumela izinqwaba zamapayipi ensimbi ukuthi zikwazi ukumelana nezimo ezimbi kakhulu kanye nezimo ezinzima.

    Njengomkhiqizi ohamba phambili embonini, i-Cangzhou Spiral Steel Pipes Group Co., Ltd. inezindawo zobuchwepheshe obuphezulu ezihlanganisa indawo engaphezu kwamamitha-skwele angu-350,000. Njengoba inenani lempahla elingafika ku-680 million yuan, sitshala imali kubuchwepheshe obusezingeni eliphezulu kanye nemishini ukuqinisekisa ukukhiqizwa kwekhwalithi ephezulu kakhulu. Ngaphezu kwalokho, abasebenzi bethu abazinikele abangu-680 baqinisekisa ukuthi yonke imikhiqizo ihlolwa ngokuqinile ngaphambi kokufinyelela ezandleni zamakhasimende ethu abalulekile.

    Ipayipi le-SSAW

    Ifektri yethu inomkhiqizo waminyaka yonke wamathani angu-400,000 wamapayipi ensimbi ajikelezayo kanye nenani lomkhiqizo elingama-yuan ayizigidi eziyizinkulungwane ezingu-1.8. Lesi sinyathelo sibonakalisa ukuzibophezela kwethu ekuletheni isevisi engcono kakhulu kanye nokuhlangabezana nezidingo zamakhasimende ethu abalulekile endaweni nasemhlabeni jikelele.

    Izinqwaba zamapayipi ensimbiKuhlanganiswe namapayipi ethu amakhulu ahlanganisiwe ahlinzeka ngokuguquguquka okuhle kakhulu, okwenza afaneleke kakhulu ezinhlotsheni eziningi zezicelo. Ngaphezu kwama-cofferdams, ama-pile ethu asetshenziswa kabanzi ekwakhiweni kwamabhuloho, ingqalasizinda yechweba kanye neminye imisebenzi yasolwandle. Umklamo oyingqayizivele ogobile noma oyindilinga walezi zinqwaba uqinisekisa ukugcinwa kwamanzi kanye nenhlabathi okuhle kakhulu ngenkathi uhlinzeka ngohlaka oluqinile lwesakhiwo.

    Ukuzibophezela kwenkampani yethu ekhwalithini, ekuqeqesheni nasekunelisekeni kwamakhasimende kusishukumisela ukuthi siqhubeke nokuthuthukisa izinqubo zethu zokukhiqiza futhi sithuthukise izixazululo ezintsha. Sinamathela ezindinganisweni eziqinile zokulawula ikhwalithi ukuqinisekisa ukuthi imikhiqizo yethu isezingeni eliphezulu futhi ihlangabezana noma idlula okulindelweyo.

    Ngokufigqiwe,izinqwaba zensimbi eziyimibhobhobaguqula imboni yokwakha ngamandla nokuqina kwepayipi lethu elihlanganisiwe elinobubanzi obukhulu. Ngekhono lazo lokubekezelela izimo ezinzima kanye nokusetshenziswa kwazo okukhethekile e-cofferdams, lezi zinqwaba zihlinzeka ngokuvikelwa nokusekelwa okungenakuqhathaniswa. Bambisana ne-Cangzhou Spiral Steel Pipes Group Co., Ltd. ukuthola imikhiqizo esezingeni eliphezulu ethuthukisa amaphrojekthi akho futhi inikeze izixazululo ezihlala isikhathi eside.
