Wave-resistant anti-collision pier for sea-crossing bridge

Abstract

The invention belongs to the technical field of bridges, in particular to a wave-resistant anti-collision pier for a sea-crossing bridge. For solving the problem that a device is easily damaged in thelong-term sea wave collision contact process, a solution is provided and is characterized in that the wave-resistant anti-collision pier includes a grouting barrel; four supporting rods distributed in an annular array mode are welded to the bottom of the circumferential inner wall of the grouting barrel; the same vertically-placed positioning pipe is welded among the four supporting rods; the topend and the bottom end of the positioning pipe are both arranged to be of a bucket-shaped structure; three auxiliary rods distributed in an annular array mode are welded to the top end of the circumferential inner wall of the positioning pipe; the same vertically-placed positioning rod is welded among the three auxiliary rods; and the positions of the positioning rod and the positioning pipe correspond to each other. According to the wave-resistant anti-collision pier, when sea waves are in collision contact with the mounting plate and the fixing plate, the impact force of the sea waves is dispersed by utilizing the irregular surfaces of the mounting plate and the fixing plate, so that the force borne by the buffer spring and the piston is reduced, and the impact of the sea waves is further reduced, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to an anti-wave and anti-collision pier for a sea-crossing bridge. Background technique [0002] Sea-crossing bridges refer to bridges across straits, bays and other seas. Piers are the main supports of bridges, mainly composed of top hats and pier bodies. The pier bodies generally include solid, hollow, and pile or column piers. The safety of bridge piers directly affects the strength of bridges. The bridge piers used by sea-crossing bridges today are assembled with assembled grouting tubes to form the pier body, and then injected with concrete grout to form the pier body. [0003] After searching, the Chinese patent application number is CN106245579A, which discloses a wave prevention method and a breakwater system using the wave prevention method. The float is provided with a cylindrical float around the shaft, and the float around the shaft is An annular two-way hydraulic dampe...

AI Technical Summary

Problems solved by technology

The above-mentioned anti-wave method and the breakwater system using the anti-wave method still have the following deficiencies: the height of the wave-releasing device cannot be adjusted according to the actual height of the sea surface and the size of the waves, and some shells will adhere to the outer surface of the pier Type of microorganisms, long-term adhesion will cause corrosion to the pier
