    Incazelo emfushane:

    Siyakwamukela eCangzhou Spiral Steel Pipe Group Co., Ltd., umkhiqizi ohamba phambili wamapayipi ahlanganisiwe ngomthungo ojikelezayo. Njengoba sineminyaka engaphezu kwengu-25 yesipiliyoni kanye nobuchwepheshe, inkampani yethu izibophezele ekuhlinzekeni ngemikhiqizo esezingeni eliphezulu ehlangabezana nezidingo zezimboni ezahlukahlukene.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Yethula:

    Ipayipi Lomugqa Wamanzi Ongaphansi KomhlabaUkufakwa bekulokhu kuyinselele enkulu kumaphrojekthi okwakha kanye nengqalasizinda. Ngokwesiko, kuhilela imisebenzi ethatha isikhathi esiningi futhi edinga umsebenzi onzima ebeka engcupheni ukuphepha kwabasebenzi kanye nezikhathi zephrojekthi. Kodwa-ke, njengoba ubuchwepheshe bokushisela amapayipi okuzenzakalelayo buthuthuka, ukwethulwa kwamapayipi ashiselwe nge-spiral kuguqula imboni.

    Ukushisela amapayipi okuzenzakalelayo: ikusasa lokwakha okuphumelelayo:

    Eminyakeni yamuva nje, ukuvela kweukushisela amapayipi okuzenzakalelayoubuchwepheshe bushintshe imboni yokwakha. Lobu buchwepheshe obusezingeni eliphezulu buqeda isidingo sokushiswa ngesandla, ngaleyo ndlela kwandiswe ukusebenza kahle, kuthuthukiswe ikhwalithi futhi kuncishiswe izindleko. Ngokuhlanganisa ukushiswa kwamapayipi okuzenzakalelayo nepayipi elihlanganisiwe eliyindilinga elenzelwe ngqo imigqa yamanzi angaphansi komhlaba, izinzuzo eziningana ezibalulekile zingatholakala.

    Amandla epayipi elihlanganisiwe elijikelezayo:

    Ipayipi elihlanganisiwe eliyi-helicaliqukethe umthungo wokushisela ojikelezayo oqhubekayo, okwenza kube yisisombululo esifanele sokufakwa kwemigqa yamanzi engaphansi komhlaba. Lawa mapayipi enziwe ngensimbi esezingeni eliphezulu, eqinisekisa ukuqina nokumelana nokugqwala, okuyizinto ezimbili ezibalulekile zokuphila isikhathi eside. Umklamo wawo oyingqayizivele unikeza amandla aphezulu kanye nobuqotho besakhiwo, okuwavumela ukuthi amelane nezingcindezi eziphezulu zangaphakathi nezangaphandle.

    Yenza kube lula ukufakwa kwemigqa yamanzi angaphansi komhlaba:

    Ukusetshenziswa kobuchwepheshe bokushisela amapayipi okuzenzakalelayo kanye namapayipi ashiselwe nge-spiral kwenza kube lula yonke inqubo yokufaka umugqa wamanzi angaphansi komhlaba. Kusukela ekumbeni kuya ekuxhumeni kokugcina, le ndlela entsha inciphisa kakhulu izindleko zabasebenzi, ifinyeze isikhathi sephrojekthi, futhi ikhuphule umkhiqizo jikelele.

    Thuthukisa ukusebenza kahle kanye nokukhiqiza:

    Izinhlelo zokushisela amapayipi ezizenzakalelayo zisusa amaphutha abantu futhi ziqinisekise ukushisela okunembile nokungaguquguquki kulo lonke ubude bepayipi. Lokhu kunemba kuhlanganiswe namandla epayipi elishiselwe ngokuzungeza kuphumela ohlelweni olusebenza kahle kakhulu olukwazi ukuphatha ukugeleza kwamanzi ngokulahlekelwa okuncane kokungqubuzana. Lokhu kusebenza okuthuthukisiwe kwe-hydraulic kwandisa umkhiqizo jikelele wesistimu yamanzi angaphansi komhlaba.

    Ukuqina okuthuthukisiwe kanye nobude besikhathi:

    Insimbi esezingeni eliphezulu esetshenziselwa ukukhiqiza amapayipi ahlanganisiwe ajikelezayo iqinisekisa ukuqina okungenakuqhathaniswa, okwenza abe yindawo ekahle kakhulu yokufakwa ngaphansi komhlaba. Ukumelana kwayo nokugqwala okuphezulu, kuhlanganiswe nokujikeleziswa okuqhubekayo okujikelezayo, kususa ingozi yokuvuza futhi kwandisa impilo yesistimu yamapayipi amanzi. Ngenxa yalokho, izindleko zokulungisa ziyancishiswa futhi isidingo sokulungiswa njalo sincishiswa kakhulu.

    Khuthaza ukuphepha kwabasebenzi:

    Ukusetshenziswa kobuchwepheshe bokushisela amapayipi okuzenzakalelayo kubeka phambili ukuphepha kwabasebenzi ngokunciphisa isidingo sokushisela ngesandla nokunciphisa izingozi ezihambisana nakho. Lobu buchwepheshe obusha buqinisekisa ukuthi abasebenzi abasachayeki entuthwini yokushisela eyingozi, izimo zokusebenza eziyingozi kanye nezingozi ezingaba khona, okudala indawo ephephile.

    Ekuphetheni:

    Ukuhlanganiswa kobuchwepheshe bokushisela amapayipi okuzenzakalelayo kanye nepayipi elihlanganisiwe elijikelezayo kushintsha ukufakwa kwemigqa yamanzi angaphansi komhlaba. Le ndlela entsha ishintsha imboni yokwakha ngokuthuthukisa ukusebenza kahle, ithuthukise ukuqina, ikhulise umkhiqizo futhi ikhuthaze ukuphepha kwabasebenzi. Njengoba siqhubeka nokwamukela lobu buchwepheshe obusezingeni eliphezulu, singalindela izinhlelo zemigqa yamanzi angaphansi komhlaba ezizinzile nezithembekile ezizohlangabezana nezidingo zesikhathi esizayo.
