Abstract

The invention discloses a protection system based on independent protection performance of a bridge pier, and provides a protection system capable of performing independent anti-collision induction and anti-collision protection on a guardrail and a chain of a bridge. Herein, a damping induction block is mounted on the guardrail, so that the guardrail can be buffered and protected in time when the guardrail is collided, the collision strength can be monitored in time, and the effects that the guardrail can be automatically protected and secondary protection can be triggered according to the collision strength are achieved. Movable damping blocks are mounted at the bottom of the guardrail, so that the limitation of the movable damping blocks can be removed in time to realize secondary damping when the guardrail is collided with a large force, and the comprehensive damping protection effect on the guardrail and a collided object is achieved. A movable protective lock chain is connected in the guardrails, so that when the lock chain is collided by certain force, a part of movement space of the lock chain can be recovered for buffering protection.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a protection system based on the independent protection performance of bridge piers. Background technique [0002] A bridge is a building built between the banks of rivers and lakes. According to the load-bearing design of the bridge, it is divided into two types for people and vehicles. When the bridge is open to traffic, it is vulnerable to collisions from vehicles. It is easy to cause damage to the bridge. [0003] At this stage, most bridges will install guardrails on both sides, and the traditional guardrails are fixed. When the guardrails are hit by external forces, they are easily damaged, and they will also cause damage to the collision objects, so that they cannot be repaired in time when a collision occurs. stop loss. Contents of the invention [0004] In view of this, the present invention provides a protection system based on the independent protection performance of bridge...
