    • IDiameter Enkulu eWelded Imibhobho yentsimbi yeePiles Tubular
    • IDiameter Enkulu eWelded Imibhobho yentsimbi yeePiles Tubular

    Inkcazelo emfutshane:

    Kuyasivuyisa ukuphehlelela imveliso yethu entsha yeemfumba zentsimbi zentsimbi, eziyilelwe ukubonelela ngokusebenzisekayo okugqwesileyo kwizicelo ezahlukeneyo, ngakumbi ii-cofferdams.Ezi mfumba zibonisa i-curved or circular overlapping design ukwenzela amandla angenakulinganiswa kunye nokuqina, ukuvala ngokufanelekileyo kunye nokuthintela ukungena kwamanzi, umhlaba kunye nesanti.


    Iinkcukacha zeMveliso

    Iithegi zeMveliso

    Iimfumba zemibhobho yentsimbizenziwa kusetyenziswa ezona mathiriyeli zikumgangatho ophezulu kunye nobuchwepheshe obuphambili, nto leyo eyenza ukuba zithembeke kakhulu kuyo nayiphi na iprojekthi yokwakha.Ezi mfumba ziqhele ukusetyenziswa kwii-cofferdams kunye noyilo lwazo oluqinileyo lwesakhiwo luqinisekisa ukhuseleko kunye nozinzo olufunekayo kwiziseko kunye neminye imisebenzi yeziseko.

    Yethuumbhobho odityanisiweyo omkhulusyintsika yale mibhobho yentsimbi, ephucula ukuthembeka nokusebenza kwayo.Ngokusebenzisa i-welding enobuchule kunye neenkqubo zokulawula umgangatho, siqinisekisa ukuba imfumba nganye ihlangabezana neyona migangatho iphezulu yoshishino.Le mibhobho inika ukuguquguquka okukhethekileyo kunye nokuqina, ivumela iimfumba zemibhobho yentsimbi ukuba zimelane neemeko ezinzima kunye neendawo ezinzima.

    Njengomvelisi ohamba phambili kwishishini, iCangzhou Spiral Steel Pipes Group Co., Ltd.Ngexabiso le-asethi ukuya kuthi ga kwi-680 yezigidi zeeyuan, sityala imali kubuchwepheshe obuphambili kunye nezixhobo zokuqinisekisa imveliso ekumgangatho ophezulu.Ngaphaya koko, abasebenzi bethu abazinikeleyo abangama-680 baqinisekisa ukuba imveliso nganye ijongwa ngokungqongqo ukuba isemgangathweni phambi kokuba ifikelele ezandleni zabathengi bethu abaxabisekileyo.

    Umbhobho we-SSAW

    Umzi-mveliso wethu unemveliso yonyaka yeetoni ezingama-400,000 zemibhobho yentsimbi ejikelezayo kunye nexabiso lemveliso ye-yuan eyi-1.8 yeebhiliyoni.Esi siganeko sibalulekileyo sibonakalisa ukuzibophelela kwethu ekunikeni inkonzo egqwesileyo kunye nokukhawulelana neemfuno zabathengi bethu abaxabisekileyo apha ekhaya nakwihlabathi jikelele.

    Iimfumba zemibhobho yentsimbikudityaniswe nemibhobho yethu enkulu edityanisiweyo edityanisiweyo ibonelela ngobuchule obugqwesileyo, ibenza bafaneleke kuluhlu olubanzi lwezicelo.Ukongeza kwii-cofferdams, iimfumba zethu zisetyenziswa ngokubanzi kulwakhiwo lweebhulorho, iziseko zophuhliso lwamazibuko kunye nezinye iiprojekthi zaselwandle.Uyilo olulodwa olugobileyo okanye olujikelezileyo lwezi mfumba luqinisekisa amanzi afanelekileyo kunye nokugcinwa komhlaba ngelixa ubonelela ngesakhelo esomeleleyo sesakhiwo.

    Ukuzinikela kwenkampani yethu kumgangatho, ubungcali kunye nokwaneliseka kwabathengi kusiqhubela ekubeni siqhubeke siphucula iinkqubo zethu zokuvelisa kunye nokuphuhlisa izisombululo ezintsha.Sibambelela kwimigangatho engqongqo yolawulo lomgangatho ukuqinisekisa ukuba iimveliso zethu zikumgangatho ophezulu kwaye ziyahlangabezana okanye zigqithise ubulindele.

    Isishwankathelo,iimfumba zetsimbi ze-tubularbaguqula ishishini lokwakha ngamandla kunye nokuqina kombhobho wethu omkhulu odityanisiweyo.Ngokukwazi kwabo ukumelana neemeko ezinzima kunye nokusetyenziswa kwabo okukhethekileyo kwii-cofferdams, ezi zifumba zibonelela ngokhuseleko kunye nenkxaso engenakulinganiswa.Sebenzisana neCangzhou Spiral Steel Pipes Group Co., Ltd. ukufumana iimveliso ezikumgangatho ophezulu eziphucula iiprojekthi zakho kwaye zinike izisombululo ezihlala ixesha elide.
