    Inqwaba Yepayipi Yensimbi Esezingeni Eliphezulu Yamaphrojekthi Okwakha

    Ipayipi Lensimbi Esezingeni Eliphezulu Lemisebenzi Yokwakha Isithombe Esivelele
    • Inqwaba Yepayipi Yensimbi Esezingeni Eliphezulu Yamaphrojekthi Okwakha
    • Inqwaba Yepayipi Yensimbi Esezingeni Eliphezulu Yamaphrojekthi Okwakha

    Incazelo emfushane:

    Izinqwaba zethu zamapayipi ensimbi zenzelwe ukuba zithembeke futhi ziqine, okwenza zibe zilungele ukusetshenziswa okuhlukahlukene kokwakha njenge-cofferdams. Izinqwaba ngayinye idlula enkambisweni yokulawula ikhwalithi eqinile ukuqinisekisa ukuthi ihlangabezana nezindinganiso eziphakeme kakhulu, ikunike ukuthula kwengqondo kuphrojekthi yakho yokwakha.

    Isingeniso Somkhiqizo

    Sethula izinqwaba zethu zamapayipi ensimbi ezisezingeni eliphezulu zamaphrojekthi okwakha, ezenzelwe ukuhlangabezana nezidingo eziqinile zezakhiwo zanamuhla. Zenziwe efektri yethu yesimanje eCangzhou, eSifundazweni saseHebei, izinqwaba zethu zamapayipi ensimbi zenziwe kusetshenziswa izinto ezinhle kakhulu nobuchwepheshe obuthuthukisiwe. Selokhu sasungulwa ngo-1993, sizibophezele ekwenzeni kahle kakhulu futhi sesibe ngumholi embonini, sihlanganisa indawo engamamitha-skwele angu-350,000 kanye nempahla iyonke engu-RMB 680 million.

    Izinqwaba zethu zamapayipi ensimbi zenzelwe ukuba zithembeke futhi ziqine, okwenza zibe zilungele ukusetshenziswa kwezinhlobo ezahlukene zokwakha njenge-cofferdams. Izinqwaba ngayinye idlula enkambisweni yokulawula ikhwalithi eqinile ukuqinisekisa ukuthi ihlangabezana nezindinganiso eziphakeme kakhulu, okukunikeza ukuthula kwengqondo kuphrojekthi yakho yokwakha. Njengoba sinabasebenzi abanekhono abangu-680, siyakwazi ukusingatha amaphrojekthi anoma yiluphi usayizi, silethe umkhiqizo ongagcini nje ngokuhlangabezana nokulindelwe, kodwa futhi odlula lokho okulindelwe.

    Kungakhathaliseki ukuthi usebenza kuphrojekthi enkulu yengqalasizinda noma iphrojekthi encane yokwakha, izinqwaba zethu zamapayipi ensimbi asezingeni eliphezulu ziyisisombululo esifanele izidingo zakho. Themba iminyaka yethu yesipiliyoni kanye nokuzibophezela ekhwalithini ukuze sikunikeze izinto ezinhle kakhulu zephrojekthi yakho yokwakha. Khetha eyethuinqwaba yepayipi lensimbingamandla azo, ukuthembeka kanye nokusebenza kwazo, futhi uzizwe umehluko ongadalwa yizinto ezisezingeni eliphezulu kuphrojekthi yakho yokwakha.

    Ipayipi le-SSAW

    Inzuzo Yomkhiqizo

    1. Njengoba zaziwa ngokuthembeka kwazo kanye nokuqina kwazo, izinqwaba zamapayipi ensimbi zilungele ukusetshenziswa kwezinhlobo ezahlukene zokwakha, njenge-cofferdams.

    2. Ukwakheka kwazo okuqinile kuqinisekisa ukuphepha nokuzinza okudingekayo ezisekelweni kanye neminye imisebenzi yengqalasizinda.

    3. Insimbi esezingeni eliphezulu esetshenziswa ekukhiqizweni kwezinqwaba zamapayipi ensimbi ibenza bakwazi ukumelana nemithwalo emikhulu futhi bamelane nezici zemvelo ezifana nokugqwala kanye nokuhamba kwenhlabathi.

    4. Izinqubo zokukhiqiza ezisetshenziswa yizinkampani ezifana nezethu, eziseCangzhou, eSifundazweni saseHebei, ziqinisekisa ukuthi inqwaba ngayinye ihlangabezana nezindinganiso zekhwalithi eziqinile, okunikeza osonkontileka nonjiniyela ukuthula kwengqondo.

    Ukushoda komkhiqizo

    1. Enye yezinkinga ezinkulu izindleko; insimbi esezingeni eliphezulu iyabiza, okungabangela ukuthi isabelomali sephrojekthi sikhuphuke.

    2. Inqubo yokufaka ingaba yinkimbinkimbi, idinga imishini ekhethekile kanye nabasebenzi abanamakhono, okungandisa isikhathi sephrojekthi.

    3. Nakuba izinqwaba zamapayipi ensimbi zihlala isikhathi eside, zingase zithinteke ezinhlotsheni ezithile zokugqwala uma zingaphathwa noma zingagcinwa kahle.

    Isicelo

    Ezweni lokwakha elihlala lishintsha, ukukhetha izinto zokwakha kunomthelela omkhulu empumelelweni nasekuphileni isikhathi eside kwephrojekthi. Enye yezinto eziye zabonakala zibalulekile yizinqwaba zamapayipi ensimbi asezingeni eliphezulu. Lezi zinqwaba zamapayipi ensimbi zenziwa ngokucophelela futhi zibalulekile ezinhlotsheni ezahlukene zezicelo zokwakha, ikakhulukazi ekwakheni isisekelo esiqinile nokuqinisekisa ubuqotho besakhiwo.

    Kwenziwe kusetshenziswa izinto ezisezingeni eliphezulu kanye nobuchwepheshe obuthuthukisiwe,ipayipi lensimbiAma-pile ayisinqumo esithembekile kunoma yimuphi umsebenzi wokwakha. Ukwakheka kwawo okuqinile kwesakhiwo kuzuzisa kakhulu ekusetshenzisweni okufana ne-cofferdams, lapho ukuzinza nokuphepha kubalulekile khona. La ma-pile ayakwazi ukumelana nemithwalo esindayo kanye nezimo zemvelo ezinzima, okwenza kube ukukhetha okuthandwayo konjiniyela kanye nabakhi.

    Ekuphetheni, ukusebenzisa izinqwaba zamapayipi ensimbi asezingeni eliphezulu kubalulekile empumelelweni yephrojekthi yokwakha. Ukuthembeka kwazo, amandla azo, kanye nezinqubo zokukhiqiza ezithuthukisiwe kuzenza zilungele amaphrojekthi ezisekelo kanye nengqalasizinda. Njengoba siqhubeka nokuthuthukisa imikhiqizo yethu, sisalokhu sizibophezele ekusekeleni imboni yokwakha ngezinto ezingcono kakhulu. Khetha izinqwaba zethu zamapayipi ensimbi zephrojekthi yakho elandelayo bese uzwa umehluko wekhwalithi nokusebenza.

    Imibuzo Evame Ukubuzwa

    Q1: Ziyini izinqwaba zamapayipi ensimbi?

    Amapayipi ensimbi ayizakhiwo eziyisilinda ezenziwe ngensimbi esezingeni eliphezulu, ezenzelwe ukushayelwa phansi emhlabathini ukuze zinikeze ukwesekwa kwesisekelo. Zenziwa kusetshenziswa ubuchwepheshe obuthuthukisiwe ukuqinisekisa ukuthi ziyahlangabezana nezidingo eziqinile zemiklamo eyahlukene yokwakha.

    Q2: Kungani ukhethe izinqwaba zamapayipi ensimbi zokwakha?

    Izinqwaba zamapayipi ensimbi zaziwa ngamandla azo nokuqina kwazo. Ukwakheka kwazo okuqinile kwesakhiwo kuzenza zilungele ama-cofferdams lapho ukuzinza kubaluleke kakhulu. Lezi zinqwaba zingamelana nemithwalo esindayo kanye nezimo zemvelo ezinzima, okwenza zibe ukukhetha okuthembekile kwezisekelo kanye neminye imisebenzi yengqalasizinda.

    Q3: Ikuphi inkampani yakho?

    Inkampani yethu yasungulwa ngo-1993 futhi itholakala eDolobheni laseCangzhou, eSifundazweni saseHebei. Ihlanganisa indawo engamamitha-skwele angu-350,000, inempahla ephelele engama-yuan ayizigidi ezingu-680, futhi okwamanje inabasebenzi abangu-680. Sizibophezele ekukhiqizeni izinqwaba zamapayipi ensimbi asezingeni eliphezulu ahlangabezana nezidingo zamakhasimende.

    Q4: Yiziphi izinyathelo zokuqinisekisa ikhwalithi ozithathayo?

    Sigxila ekhwalithini kuzo zonke izigaba zokukhiqiza. Amapayipi ethu ensimbi akhiqizwa kusetshenziswa izinto ezisezingeni eliphezulu futhi asebenzisa ubuchwepheshe obuthuthukisiwe ukuqinisekisa ukuthembeka. Inqubo yethu eqinile yokulawula ikhwalithi iqinisekisa ukuthi imikhiqizo yethu ihlangabezana nezindinganiso zemboni kanye nemininingwane yamakhasimende.
