    Inqwaba Yepayipi Lensimbi Esezingeni Eliphezulu Yemiklamo Yokwakha

    Inqwaba Yepayipi Lensimbi Yekhwalithi Ephakeme Yemiklamo Yokwakha Isithombe Esifakiwe
    • Inqwaba Yepayipi Lensimbi Esezingeni Eliphezulu Yemiklamo Yokwakha
    • Inqwaba Yepayipi Lensimbi Esezingeni Eliphezulu Yemiklamo Yokwakha

    Incazelo emfushane:

    Izinqwaba zamapayipi ethu ensimbi aklanyelwe ukuba athembeke futhi ahlale isikhathi eside, awenze afaneleke ezinhlobonhlobo zezicelo zokwakha ezifana nama-cofferdam. Inqwaba ngayinye ibhekana nenqubo eqinile yokulawula ikhwalithi ukuze kuqinisekiswe ukuthi ihlangabezana nezindinganiso eziphakeme kakhulu, ikunikeza ukuthula kwengqondo kuphrojekthi yakho yokwakha.

    Isingeniso Somkhiqizo

    Sethula izinqwaba zamapayipi ensimbi ezisezingeni eliphezulu zamaphrojekthi wokwakha, aklanyelwe ukuhlangabezana nezidingo eziqinile zezakhiwo zesimanje. Ekhiqizwe efekthri yethu esezingeni eliphezulu e-Cangzhou, esiFundazweni sase-Hebei, izinqwaba zamapayipi ensimbi zethu zenziwa kusetshenziswa izinto ezinhle kakhulu kanye nobuchwepheshe obuphambili. Kusukela sasungulwa ngo-1993, sizibophezele ekwenzeni kahle futhi sesingaba umholi wemboni, ehlanganisa indawo engamamitha-skwele angu-350,000 kanye nempahla ephelele ye-RMB 680 million.

    Izinqwaba zamapayipi ethu ensimbi aklanyelwe ukuba athembeke futhi ahlale isikhathi eside, awenze afaneleke ezinhlobonhlobo zezicelo zokwakha ezifana nama-cofferdam. Inqwaba ngayinye ibhekana nenqubo yokulawula ikhwalithi eqinile ukuze kuqinisekiswe ukuthi ihlangabezana nezindinganiso eziphakeme kakhulu, ikunikeza ukuthula kwengqondo kuphrojekthi yakho yokwakha. Njengoba sinabasebenzi abanekhono abangama-680, siyakwazi ukuphatha amaphrojekthi anoma yibuphi usayizi, siletha umkhiqizo ongafinyeleli nje kuphela okulindelekile, kodwa okudlulayo.

    Kungakhathaliseki ukuthi usebenza kuphrojekthi yengqalasizinda enkulu noma iphrojekthi encane yokwakha, izinqwaba zamapayipi ensimbi yethu yekhwalithi ephezulu ziyisixazululo esiphelele sezidingo zakho. Themba iminyaka yethu yokuhlangenwe nakho nokuzibophezela kukhwalithi ukuze sikunikeze izinto ezingcono kakhulu zephrojekthi yakho yokwakha. Khetha yethuinqwaba yepayipi lensimbingamandla abo, ukuthembeka nokusebenza, futhi uzwe umehluko ongawenza izinto zekhwalithi ephezulu kuphrojekthi yakho yokwakha.

    Ipayipi le-SSAW

    Inzuzo Yomkhiqizo

    1. Eyaziwa kakhulu ngokuthembeka namandla ayo, izinqwaba zamapayipi ensimbi zilungele izinhlelo zokusebenza ezihlukahlukene zokwakha, njengama-cofferdam.

    2. Isakhiwo sabo esiqinile sesakhiwo siqinisekisa ukuphepha nokuzinza okudingekayo ezisekelweni neminye imisebenzi yengqalasizinda.

    3. Insimbi yekhwalithi ephezulu esetshenziswa ekukhiqizeni izinqwaba zamapayipi ensimbi ibenza bakwazi ukumelana nemithwalo emikhulu futhi bamelane nezinto ezizungezile ezifana nokugqwala nokunyakaza kwenhlabathi.

    4. Izinqubo zokukhiqiza ezisetshenziswa izinkampani ezinjengezethu, eziseCangzhou, esifundazweni saseHebei, ziqinisekisa ukuthi inqwaba ihlangabezana nezindinganiso eziqinile zekhwalithi, inika osonkontileka nonjiniyela ukuthula kwengqondo.

    Ukushoda komkhiqizo

    1. Enye yezinto eziyinhloko izindleko; insimbi yekhwalithi ephezulu iyabiza, engabangela isabelomali sephrojekthi sande.

    2. Inqubo yokufaka ingaba yinkimbinkimbi, idinga imishini ekhethekile kanye nomsebenzi wamakhono, okunganweba isikhathi sephrojekthi.

    3. Nakuba izinqwaba zamapayipi ensimbi zihlala isikhathi eside, zingase zibe lula ezinhlotsheni ezithile zokugqwala uma zingaphathwa noma zinganakekelwa kahle.

    Isicelo

    Ezweni elihlala lishintsha lokwakha, ukukhethwa kwezinto kunomthelela omkhulu empumelelweni nempilo ende yephrojekthi. Enye impahla ebonakale ibalulekile izinqwaba zamapayipi ensimbi ezisezingeni eliphezulu. Lezi zinqwaba zamapayipi ensimbi zikhiqizwa ngokucophelela futhi zibalulekile ezinhlobonhlobo zezicelo zokwakha, ikakhulukazi ekudaleni isisekelo esiqinile nokuqinisekisa ubuqotho besakhiwo.

    Kwenziwe kusetshenziswa izinto ezisezingeni eliphezulu kakhulu nobuchwepheshe obuphambili,ipayipi lensimbiizinqwaba ziyisinqumo esithembekile kunoma iyiphi iphrojekthi yokwakha. Idizayini yabo yesakhiwo eqinile inenzuzo ikakhulukazi ezinhlelweni ezifana nama-cofferdam, lapho ukuzinza nokuphepha kubaluleke kakhulu. Lezi zinqwaba ziyakwazi ukumelana nemithwalo esindayo kanye nezimo zemvelo ezinzima, okuzenza zibe ukukhetha okuthandwayo konjiniyela nosonkontileka.

    Sengiphetha, ukusebenzisa izinqwaba zamapayipi ensimbi ezisezingeni eliphezulu kubalulekile empumelelweni yephrojekthi yokwakha. Ukuthembeka kwabo, amandla, kanye nezinqubo zokukhiqiza ezithuthukile zibenza balungele izisekelo namaphrojekthi engqalasizinda. Njengoba siqhubeka nokusungula futhi sithuthukisa imikhiqizo yethu, sihlala sizibophezele ekusekeleni imboni yezokwakha ngezinto ezingcono kakhulu. Khetha izinqwaba zamapayipi ethu ensimbi kuphrojekthi yakho elandelayo futhi uzwe umehluko wekhwalithi nokusebenza.
