Bridge pier outer pier anticollision device

Abstract

The invention provides a bridge pier outer pier anticollision device, mainly comprising an underwater measurement device, an ultrasonic transmitting receiver, a control processing system, a positioning transmission system and a power supply system, wherein the underwater measurement device is fixed on an underwater pier, the ultrasonic transmitting receiver is fixed on the underwater measurement device, the control processing system controls the ultrasonic transmitting receiver, and measures distance between the transmitting terminal of the ultrasonic transmitting receiver and the surface of ameasured riverbed. Measured data are summarized and transmitted to a bridge monitoring system of a bridge monitoring department by the positioning transmission system. The anticollision device can completely replace existing manual ship measurement, realizes autonomous power supply by utilizing solar energy, can measure the transmission data in real time, and can perform digital simulation on thedepth and distribution range of scour pits, so as to achieve the aim of intermittently monitoring the depth of the pier scour pits and the distribution condition of the scour pits, help the bridge monitoring department to send out alarm in time in the flood season, and avoid unnecessary life and property loss.

Description

technical field [0001] The invention relates to an anti-collision device for an outer pier of a bridge pier, and belongs to the technical field of anti-collision devices for bridge piers. Background technique [0002] With the needs of social development and transportation, the construction of bridges on water is developing rapidly. The construction of bridges across rivers and seas relieves the pressure of land transportation and promotes the development of waterway transportation. However, due to many factors such as the natural environment, navigation environment, ship conditions, ship operators and managers, the collision of ships and bridges occurs frequently, which directly causes immeasurable casualties, property losses and environmental pollution. Bridge anti-collision measures must be taken to reduce the damage to the bridge structure. General bridge anti-collision facilities use devices with rubber pads and springs to buffer the impact of ships on the bridge piers...

AI Technical Summary

Problems solved by technology

However, due to many factors such as the natural environment, navigation environment, ship status, ship operators and managers, accidents of ships colliding with bridges occur frequently, directly causing incalculable casualties, property losses and environmental pollution. Therefore, Crash prevention measures for bridges must be taken to mitigate damage to bridge structures

Generally, bridge anti-collision facilities use devices with rubber pads and springs to buffer the impact of ships on bridge piers, but the impact energy absorbed by such devices is very small, and the remaining impact energy still causes huge damage to bridge piers, and the protection effect is not good. need to be improved
