The invention relates to a bridge support comprising an upper support body and a lower support body, wherein supporting components are arranged between the upper support body and the lower support body; the supporting components comprise a convex lining board, a concave lining board, a steel basin and a steel sleeve; the steel basin is arranged at the outer side of the concave lining board; the upper part of the steel sleeve wraps the periphery of the steel basin; the inner side of the lower part of the steel sleeve is provided with an annular groove; the lower support body is arranged in theannular groove; a sealed filling cavity is formed among the lower support body, the steel sleeve and the steel basin; pipelines communicating with the filling cavity are opened in the lower support body; the bottom of the upper support body is provided with a clamping groove; and the convex lining board is embedded in the clamping groove. The self-adaptive bridge support has the characteristics ofadjusting the bearing capacity of the support and satisfying the change of the rotation angle and self-resetting of a bridge.
Description
technical field [0001] The invention relates to the technical field of road bridges, in particular to an adaptive bridge support. Background technique [0002] With the development of the national economy, the role of transportation infrastructure construction in promoting the development of the national economy is also becoming more and more significant, among which bridge construction occupies a considerable proportion in the construction of transportation infrastructure. In bridge engineering, railway and highway bridges can reliably transmit the reaction force and deformation of the upper structure of the bridge to the lower structure of the bridge through the bearings, thereby improving the stability of the bridge. [0003] In addition to the horizontal thrust and vertical pressure, the external force on the support also has the influence of the bias pressure caused by the rotation of the beam body on the support. Spherical bearing is currently the most widely used and...
