Early warning and protective method for collision resistance of bridge piers

Abstract

The invention provides an early warning and protective method for collision resistance of bridge piers. The method includes that step one, an electronic induction device detects ships within a certain sea area range and amplifies detected physical signals into electrical impulse signals, when the ships sail into a monitored and early warned area, a control system controls an alarm system to raise the alarm, and the ships can adjust sailing directions; step two, when the ships move on and sail into danger areas, the control system controls output of high-low levels to achieve early warning and/or protective functions according to the sizes of the electrical impulse signals; and step three, when the ships leave the monitored sea area after collision and the electronic induction device cannot detect signals, the control system controls reset of an early warning and protective system so as to achieve recycling. According to the early warning and protective method, early warning and protection are combined, ship-bridge collision accidents can be avoided effectively by the aid of intelligent early warning, and the protective system does not occupy navigation channels and not prone to corrosion by seawater and capable of being recycled under the normal state.

Description

technical field [0001] The invention relates to the field of bridge safety monitoring and maintenance, in particular to an intelligent control method for anti-collision warning and protection of bridge piers. Background technique [0002] With the development of transportation in our country, there are more and more cross-sea and river-crossing bridges, and the waterway traffic becomes more and more busy, resulting in the frequent occurrence of catastrophic accidents of ships hitting bridges. According to the momentum theorem △mv=F△t, when a ship hits a bridge pier, the speed is fast, the time is short, and the impact force is large, which can easily lead to the collapse of the bridge and cause huge economic losses. For example, the 6.15 incident of the Guangdong Jiujiang Bridge that caused a national sensation, the bow of the "Nangui Ji 035" collided with the No. 23 pier of the Jiujiang Bridge, resulting in the collapse of the three piers of No. 23, 24 and 25 of the Jiujian...

AI Technical Summary

Problems solved by technology

The existing protection system is difficult to realize real-time monitoring, early warning and protection against ship collision with the bridge, and the protection system is not easy to repair and replace, and the reuse value is very low
