Central cable cable-stayed bridge front fulcrum hanging basket walking system and construction method
The invention discloses a central cable cable-stayed bridge front fulcrum hanging basket walking system which comprises a beam top bearing main truss walking mechanism and a front fulcrum hanging basket bottom basket walking mechanism. The beam top bearing main truss walking mechanism comprises a sliding beam, a front wheel, a rear wheel, a front bracket, a rear bracket, a front cushion block, a rear cushion block, a jacking mechanism, a main truss walking counter-force device, a balancing weight, a limiting device, a sliding beam rear anchor rod set and a sliding beam middle anchor rod set. The front fulcrum hanging basket bottom basket walking mechanism comprises a front hanging point sliding device, an active walking hanging bracket, a front hanging point sliding device, a steel hanging belt, a bottom basket walking counter-force device, a bottom basket rear anchor rod set and a bottom basket middle anchor rod set. Meanwhile, the invention further discloses a central cable cable-stayed bridge front fulcrum hanging basket walking construction method. The segmental suspension pouring device is used for segmental suspension pouring construction of a concrete girder of a cable-stayed bridge, and has the characteristics of safety, reliability, reasonable structure, simplicity in operation, high walking precision, labor saving and the like.
