technical field

The utility model relates to the technical field of bridge bases, in particular to a bridge shock absorption base.

Background technique

Bridges generally refer to structures erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern and fast-developing transportation industry, bridges are also extended to cross mountain streams, bad geology or to meet other traffic needs. The bridge is generally composed of the upper structure, the lower structure, the support and the auxiliary structure. The support is the force transmission device set at the support place of the bridge span structure and the bridge pier or abutment, and it also bears the vibration and seismic load during operation. It can reliably transmit the reaction force and deformation (displacement and rotation angle) of the upper structure of the bridge to the lower structure of the bridge, so that the actual stress of the structure is consistent with the calculated theoretical schema. Structural earthquake resistance, reducing earthquake hazard and effective technology are widely used in various fields.

However, most of the existing bridge supports have stronger protective measures and do not have shock absorption.
