Abstract
The utility model discloses a kind of municipal anti-seismic bridge piers, it is related to bridge pier technical field, including base, the top of base is welded with bottom plate, and the top of bottom plate is connected with pier body;The inside annular equidistance of base is equipped with mounting groove, and the inside of mounting groove is provided with sleeve pipe, and the inside screw thread connection of sleeve pipe is limited to limit rod;The surface of sleeve pipe is connected with first bevel gear, and the top of first bevel gear is connected with second bevel gear;The surface of limit rod is equipped with moving groove, and the inside sliding connection of moving groove is with the fixed connection of the connecting strip in mounting groove inner wall.The utility model in, by the rotation of annular plate, limit rod can be deeply into soil mass, increase the friction and anchoring force of pier and soil mass by mechanical bite cooperation after, form stable constraint system, reduce the slippage and overturning risk of pier when earthquake, enhance the overall stability of structure, to improve seismic performance.
