METHOD FOR REINFORCED CONCRETE BRIDGE CONSTRUCTION Russian patent published in 2006 - IPC E01D21/00 E01D12/00 

FIELD: bridge construction, particularly to erect bridges and overpasses during panel and ribbed panel span structures erection.

SUBSTANCE: method involves concreting beams of monolithic ribbed panel span structure with the use of form arranged in bridge span. The span structure includes single section. Method for span structure erection involves separating span structure into strips; installing outer form on falsework and piers over full strip section; forming inner form as bottomless timber or metal box, wherein the inner form is used only for concreting bottom, walls and membranes of span structure; performing concreting works with the use of inner form up to lower panel bottom level; removing the box as concrete has get strength; filling gaps between membranes and walls with sand; covering sand surface with film-forming composition; pouring reinforced concrete of roadway panel over full bridge section; hardening concrete; removing sand through orifices made in span structure beam bottom under gravity; moving outer form to the next strip and performing new concreting cycle.

EFFECT: increased simplicity and reduced costs.
