METHOD FOR ERECTION OF STEEL-REINFORCED CONCRETE SUPERSTRUCTURE OF BRIDGE Russian patent published in 2000 - IPC

FIELD: bridge-building industry. SUBSTANCE: according to method, following processes are carried out: production in factory conditions of T-shaped blocks each of them consisting of united metal girders and reinforced concrete slab of ballast trough, manufacturing of lateral links, transportation of blocks to site of bridge erection, installation of blocks in pairs in design position, each block being installed at different sides as to longitudinal axis of bridge with formation of clearances between slabs of adjacent blocks, integration of blocks in each pair to each other and making joint between slabs in adjacent blocks. Lateral links are installed between girders of each pair of adjacent blocks with clearances with respect to slab of ballast trough. Lateral links are installed at construction site after installing each T-shaped block in design position or lateral links are installed at construction site prior to installing T-shaped blocks to design position with subsequent simultaneous erection in design position of pair of adjacent T-shaped blocks united into single module. Application of aforesaid method allows for reduction of labour-intensity during erection procedure together with simultaneous reduction of material input. Service life of structure is also prolonged. EFFECT: higher efficiency. 9 cl, 3 dwg
