High-speed rail bridge support seismic isolation system

Abstract

The invention discloses a high-speed rail bridge support seismic isolation system. The structure of the system comprises a pressure sensor, a seismic isolating rubber support, inner connecting bolts,a silica gel sealing plate, a rubber protection layer sleeve, outer connecting bolts, a steady steel plate layer, a seismic isolating lead core, a seismic reducing rubber layer, a connecting steel plate, a pre-embedded steel plate, a bridge sleeve, and bridge pre-embedded ribs. The pressure sensor is provided with a pressure sensing cap, a sensing cap nested groove, a sensor threaded stud, a sensing data wire, a tail cap nested groove, and a sensor tail cap. The high-speed rail bridge support seismic isolation system realizes high leakproofness and smooth and efficient cooperation and connection of each component, transmits real-time test data of load of pressure and capacity of a bridge, and stores the data and provides to-be-improved load and load values for personnel who performs maintenance and protection at fixed time, so the personnel can change high-strength load materials to improve seismic isolation effect.

Description

technical field [0001] The invention relates to an anti-vibration and isolation system for a high-speed railway bridge support, which belongs to the field of anti-vibration and isolation system equipment. Background technique [0002] When building a railway, it often encounters rivers, valleys, highways or crosses with another railway. In order to allow the railway to cross these terrain obstacles, various railway bridges need to be built. Railway bridges have large loads, large impact forces, and high traffic density, requiring high standards for resistance to natural disasters, especially for structures that require certain vertical and lateral stiffness and dynamic performance. [0003] Bridge bearings are important structural components connecting the bridge superstructure and substructure. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the bridge superstructure to the bridge substructure, so that the actual stress of t...
