Shockproof protection device for roads and bridges

The invention relates to the technical field of road bridges, and discloses a shockproof protection device for roads and bridges; the device comprises a plurality of energy absorption structures evenly distributed between a cover beam and a main beam, and each energy absorption structure comprises a plurality of supporting seats, a plurality of sliding blocks, a plurality of first damping springs and a plurality of second damping springs. The multiple supporting seats are fixed to the end face, close to the main beam, of the cover beam, annular grooves are formed in the end faces, close to the main beam, of the supporting seats, multiple energy absorption grooves are evenly distributed in the supporting seats in the circumferential direction of the supporting seats, the multiple sliding blocks are evenly arranged in the annular grooves, and the upper end faces of the sliding blocks are in sliding fit with the lower end face of the main beam. And the multiple first damping springs are connected between the sid
