Embodiment Construction

[0028] Below in conjunction with accompanying drawing and example the patent of the present invention is described further:

[0029] see figure 1 , The pier scour monitoring system is divided into two parts, the wet end and the dry end. The wet end is composed of depth sounder array and current meter; the dry end is composed of signal processor, electronic cabin, flushing data processing, early warning and evaluation system; the dry end and wet end are connected by watertight cables, and the signal processor and electronic cabin calculate Data such as the depth and flow rate of the water are transmitted to the flushing data processing, early warning and evaluation system through the optical cable.

[0030] The depth sounder structure can be found in figure 2 First, assemble the left wind deflector 4, sounding transducer 5, and right wind deflector 6 with hex bolt 1, spring washer 9, and hexagon nut 10, and place the depth sounding transducer 5 in the circle of the left and ...

Abstract

The invention provides a real-time bridge pier scouring monitoring system. The real-time bridge pier scouring monitoring system can stably work for a long time in a high-velocity water flow environment, is high in precision and efficiency, is simple and convenient to mount and is economical and practical. The system comprises a depthometer array, a current meter, a signal processor, an electronic cabin and a scouring data processing, early-warning and evaluating system, wherein depthometers are used for firstly measuring the sound velocity by utilizing a reflection rod method and calculating the scouring depth according to the measured sound velocity; the signal processor is used for controlling the emission and receiving of sound signals of a depth-sounding transducer in the depthometer array and calculating the water depth according to the collected data; the current meter is used for measuring a water flow state; the scouring data processing, early-warning and evaluating system is used for analyzing data change situations of different periods and establishing a model for predicting the scouring of a bridge. The system is good in measurement accuracy, high in measurement efficiency, compact in structure and good in maintainability and can stably and reliably work for a long time.

Description

technical field [0001] The invention belongs to the technical field of bridge monitoring and safety early warning, and in particular relates to a system and an implementation method for real-time monitoring of the impact of water flow on pier scour. Background technique [0002] Scouring is an important cause of bridge damage, and many bridges are destroyed by floods every year in countries all over the world. According to statistics, among the 1,000 bridges that collapsed in the United States, 60% were caused by floods scouring bridge piers. A large number of bridges in our country have potential safety hazards and are vulnerable to damage during floods. In 2010, the Laodingjiang Bridge in Chongzhou City, Sichuan Province collapsed, and the two piers of the Baocheng Railway Crossing the Shitingjiang Bridge were washed away, all because of the continuous erosion of mountain torrents, which caused the bridge foundation to collapse. [0003] It is the development trend of br...
