    Incazelo emfushane:

    Siyajabula ukwethula amaphayiphu ethu womkhiqizo wensimbi entsha, enzelwe ukuhlinzeka ngosizo oluhle kakhulu ezinhlobonhlobo zezicelo, ikakhulukazi ama-cofferdams. Lezi zinqwaba zibonisa ukwakheka okugoqiwe noma okujikelezayo okuphezulu kwamandla angenakuqhathaniswa nokuqina, kufakwe ngempumelelo nokuvimbela ukungena kwamanzi, inhlabathi nesihlabathi.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Izinqwaba zepayipi lensimbiakhiqizwa esebenzisa izinto ezisezingeni eliphakeme kakhulu nobuchwepheshe obuthuthukisiwe, okwenza bathembeke kakhulu kunoma yimuphi umsebenzi wokwakha. Lezi zinqwaba zisetshenziswa kakhulu kuma-cofferdams futhi idizayini yazo eqinile yokwakheka kuqinisekisa ukuphepha nokuqina okudingekayo ukuthola izisekelo kanye nezinye izingqalasizinda zisebenza.

    -KwethuUbubanzi obukhulu budedelwe ipayipisbangumgogodla walezi zinqwaba zensimbi yensimbi, ethuthukisa ukuthembeka kwabo nokusebenza. Ngezinqubo zokulawulwa kwe-welding ezimnandi kanye nekhwalithi, siqinisekisa inqwaba ngayinye ihlangana namazinga aphezulu embonini. Lawa mapayipi anikela ngokuguquguquka okuhlukile nokuqina, okuvumela izinqwaba zepayipi zensimbi ukuba zibekezelele izimo ezimbi kakhulu kanye nezindawo ezinokhahlo.

    Njengomenzi oholayo embonini, iCangegzhou Spiral Steel Pipes Group Co, Ltd. Inezikhungo zombuso ezimboze indawo yamamitha-skwele angaphezu kwama-350,000. Ngenani lempahla elifinyelela ku-680 million yuan, sitshala imali kubuchwepheshe obunqenqemeni nemishini ukuqinisekisa ukukhiqizwa kwekhwalithi ephezulu kakhulu. Ngaphezu kwalokho, abasebenzi bethu abazinikele babasebenzi abangama-680 baqinisekisa ukuthi wonke umkhiqizo uhlola amasheke ajwayelekile ngaphambi kokufika ezandleni zamakhasimende ethu afanele.

    Ipayipi le-SSAW

    Ifektri yethu inomphumela waminyaka yonke wamathani angama-400,000 amapayipi ensimbi e-Spiral kanye nenani lokukhipha le-1,8 billion yuan. Le mpistone ikhombisa ukuzibophezela kwethu ekuletheni ukusebenza kahle kwemisebenzi nokuhlangabezana nezidingo zamakhasimende ethu abaluleke endaweni yangakini nasemhlabeni jikelele.

    Izinqwaba zepayipi lensimbiKuhlanganiswe namapayipi ethu amakhulu we-weldeter anikezela ngezindlela ezinhle kakhulu zokuhlobisa, ukuzenza zilungele izinhlelo eziningi zezicelo. Ngaphezu kwama-cofferdams, izinqwaba zethu zisetshenziswa kabanzi ebhulohweni lokwakhiwa, ingqalasizinda yebhasi namanye amaphrojekthi wasolwandle. Umklamo oyingqayizivele noma oyindilinga walezi zinqwaba uqinisekisa amanzi afanele nokugcinwa kwenhlabathi ngenkathi enikeza uhlaka oluqinile lwesakhiwo.

    Ukuzibophezela kwenkampani yethu kwekhwalithi, ubuchwepheshe kanye nokweneliseka kwamakhasimende kusishayela ukuze sithuthukise izinqubo zethu zokukhiqiza futhi sithuthukise izixazululo ezintsha. Sinamathela emazingeni aqinile okulawula asezingeni ukuze aqinisekise ukuthi imikhiqizo yethu inekhwalithi ephezulu kakhulu futhi ihlangabezana noma idlule okulindelwe.

    Ngokufigqiwe,I-Steel Tubular Tilesbaguqula imboni yezokwakha ngamandla nokuqina kwepayipi lethu elikhulu eliveziwe. Ngamandla abo okubekezelela izimo eziyinselele kanye nokusetshenziswa kwazo okukhethekile kuma-cofferdams, lezi zinqwaba zinikeza ukuvikela nokusekelwa okungekho emthethweni. Uzakwethu ngeCangegzhou Spiral Steel Pipes Group Co, Ltd ukuthola imikhiqizo esezingeni eliphezulu ethuthukisa amaphrojekthi akho futhi ahlinzeke ngezixazululo ezihlala njalo.
