Problems solved by technology

[0002] The existing viaduct structure has the following problems: 1. When the vehicle on one side of the bridge is overloaded, there will be relative sliding and rotation between the bridge deck structure and the bridge pier, which cannot be automatically reset after sliding, which will easily cause the bridge deck structure to slip and overturn laterally; 2. The rubber vibration isolation pads on the pier have aging problems and are not easy to replace; 3. When the load is applied, generally only the vibration isolation pads on the side where the load is applied work, and the vibration isolation effect is limited

Abstract

The self-resetting, anti-overturning and efficient damping system comprises a bridge superstructure, concrete-filled steel tube piers are arranged below the bridge superstructure in a bilateral symmetry mode, and concrete-filled steel tube arch connecting beams are arranged between the tops of the adjacent concrete-filled steel tube piers and the bridge superstructure. A hydraulic vibration isolation pad is arranged between the top of the concrete-filled steel tube pier and the bridge superstructure, and a prestress inhaul cable is arranged between the side portion of the concrete-filled steel tube pier and the bridge superstructure. The system has the advantages of being high in bearing capacity, good in integrity, high in energy dissipation capacity, convenient to machine and manufacture and the like.

Description

technical field [0001] The invention relates to a viaduct self-resetting, anti-overturning, high-efficiency shock absorption system and a construction method thereof. Background technique [0002] The existing viaduct structure has the following problems: 1. When the vehicle on one side of the bridge is overloaded, there will be relative sliding and rotation between the bridge deck structure and the bridge pier, which cannot be automatically reset after sliding, which will easily cause the bridge deck structure to slip and overturn laterally; 2. The rubber vibration isolation pads on the bridge piers have aging problems and are not easy to replace; 3. When the load is applied, generally only the vibration isolation pads on the load-applied side play a role, and the vibration isolation effect is limited. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a viaduct self-re...
