Adjustable Slope-shaped Bearing and its Quick Installation Method for Long and Large Longitudinal Slope Bridges with High Piers

Abstract

With the rapid development of society, the number of bridges in China has increased rapidly. Under various complex environmental conditions, the construction and maintenance of bridges become more complicated. Bearings are the most vulnerable part of a bridge, and due to multiple factors, pier bearings tend to be on the small side, susceptible to damage, and difficult to install and maintain. In this paper, a method for customizing special slope bearings according to the slope requirements of different piers is proposed. As long as the installation position and direction of the bearing are correct under the premise of standard construction, the slope requirements of the bridge can be met, the self-recovery performance of the long longitudinal slope bridge after sliding can be realized, the structural safety can be guaranteed, the durability of the sloping bridge can be improved, and the maintenance cost of the bridge in the later stage can be reduced.
