Anti-floating anchor bolt structural system for bridge
The invention discloses an anti-floating anchor bolt structural system for a bridge. The anti-floating anchor bolt structural system is characterized in that a special-shaped steel bar is embedded in a bridge abutment, so that lower anchoring is completed, and a helical steel bar in a laying layer is connected with an n-shaped steel bar, so that upper anchoring is completed, and as a steel sleeve is arranged in a post-pouring hinge joint, vertical connection is completed; the steel sleeve is filled with stone matrix asphalt cement; a swing rabbet is formed in the sliding end of the bridge and is further filled with stone matrix asphalt cement, therefore the shrinkability of the bridge is ensured; besides, with the adoption of the special-shaped steel bar anchor bolt component, the problems of anti-floating and shock resistance of the bridge are solved while the anti-seismic and falling-off prevention functions of the bridge are ensured, the construction is fast and convenient, the cost is low, the maintenance cost is low and higher economic and social benefits are achieved.
