Bridge pier impact force monitoring device

Abstract

The invention discloses a bridge pier impact force monitoring device. The bridge pier impact force monitoring device comprises a liquid level sensor used for acquiring data of the water level of a river channel, a flow velocity sensor used for acquiring data of the flow velocity of river water, a data acquisition circuit used for acquiring data of the liquid level sensor and data of the flow velocity sensor, and a control circuit used for analyzing and processing the data and having control over an alarm circuit. The bridge pier impact force monitoring device detects impact force of the river water, and gives an alarm when the impact force reaches the limit of the bearing capacity of a bridge, and the situation that because a bridge collapses, lives and properties of people are threatened is avoided.

Description

[0001] technical field

[0002] The invention relates to the field of monitoring devices for pier and bridge conditions, in particular to a device for monitoring the impact force of bridge piers. Background technique

[0003] Most of the bridges are built on the river, and the river water has a strong impact on the bridge piers, and the water level of the river has a great influence on the bridge. In summer, every flood season, the water level of the river rises sharply, and the impact force of the river water on the bridge piers increases, which poses a severe test to the bridge. The bridge is safe under a certain impact force, but if the water level rises or / and the water speed increases, the impact force of the water on the bridge will increase, and the bridge will easily collapse. For example, in the summer of 2010, the water level suddenly rose and the water flow accelerated, making The collapse of the Guanghan Shitingjiang Railway Bridge caused two carriages of the K...
