Ntchito yomanganso Kukweza mozungulira pa Harbin East Third Ring Highway

Aka kanali koyamba ku China kukweza kozungulira koyambira, koyamba kokweza kapu yokhazikika, komanso kutalika kokwezeka kwambiri kwa girder ya double crane frame mdera la alpine kudachita bwino. Harbin East Third Ring Highway Project, yomwe yakhazikitsa zolemba zingapo, idatsegulidwa mwalamulo kwa magalimoto. Mogwirizana ndi mfundo zopulumutsira ndalama za polojekiti, kulimbikitsa chitukuko chobiriwira ndikukwaniritsa zofunikira zakukonzekera kwa polojekiti yonse, likulu la ntchito yomangamangayo lidatengera kapangidwe kake kakukweza kokweza kuti kukweze mlatho wakale wakale, kuti ugwirizane nawo. mlatho watsopano.

Pambuyo pa ntchito ya tsiku ndi tsiku ndikuyankhulana, pokhala ndi chidziwitso chochuluka pakukweza mlatho wofanana, kampaniyo inaganiza zotengera njira yoyenera pogwiritsa ntchito synchronous system ndi hydraulic silinda, ndipo pamapeto pake ikwaniritsa zofunikira zomanga.

Gululo lidaganiza zotengera kukweza kosinthira kozungulira, koyambirira, gululo lidakumana ndi zovuta zingapo zaukadaulo, kutalika kwa 6.897 metres, kusintha kwa mphamvu ya span ndi mbale yamtengo, kukweza kulemera kwa gawo la pier. , kapu ndi makina osungiramo ma bridge akufikira matani 32,000, ndipo vuto lonse lokhazikitsa siliyenera kukhala lachiwiri mdziko muno. Komabe, Canete adachita zovutazo ndikukhazikitsa gulu laukadaulo lolumikizana ndi anthu, pogwiritsa ntchito luso lake laukadaulo komanso luso lazachuma pazaka zambiri, ndipo pamapeto pake adasintha makina onyamula ma point angapo kuti akwaniritse zomwe polojekitiyi ikufuna, dongosolo lomwe lingasinthe ngodya imasintha pamakwerero osiyanasiyana okweza ndikuwongolera nthawi yeniyeni panjira yonse ya digito. Kuonetsetsa chitetezo cha zomangamanga pamalopo komanso chitukuko chokhazikika cha ntchito zokweza.

Pulojekitiyi idasankha Jiangsu Canete's four-point frequency conversion synchronous lifting hydraulic system, komanso ma seti 230 a 320T ma hydraulic silinda akuluakulu okhala ndi sitiroko ya 140mm. Imakwaniritsa zofunikira zaukadaulo wapa denga lamitundu ingapo, kuwongolera kosalekeza komanso kotalika, kusuntha kofananira, pomaliza kumapangitsa kuti athe kuzindikira kuwongolera kolumikizana kwa milathoyo.
