Sonar scanning-based underwater structure damage and riverbed scour detection method

Abstract

The invention discloses a sonar scanning-based underwater structure damage and riverbed scour detection method. The method includes the following steps that: step 1, measurement points are arranged after preparations are made; step 2, an operating platform is installed, and a scanning system is connected; step 3, after the scanning system is wired and debugged so as to be eligible, and a sonar system performs scanning; step 4, a damage part is scanned; and step 5, a picture is processed and analyzed. With the method of the invention, an effective solution is provided for the timely, accurate and effective collection of underwater structure damage data and riverbed scour data; powerful data support is provided for the evaluation of the damage of the underwater structure and the scour condition of a riverbed; and a foundation is laid for accelerating and improving the detection and governance of the damage of the underwater structure and the scour of the riverbed; and a new impetus is provided for infrastructure maintenance.

Description

technical field [0001] The invention relates to a detection method, in particular to a detection method for underwater structure damage and river bed scour based on sonar scanning. Background technique [0002] At present, the judgment of underwater structure damage and river bed erosion is mainly obtained through the analysis of divers' manual exploration and ultrasonic detection data. Among them, the damage of the underwater structure is mainly estimated by divers' manual exploration and image data analysis to estimate the damage situation and damage range of the structure; while the riverbed scour mainly collects the depth data of the riverbed at each measuring point through ultrasonic detection, and through the comparison with the initial riverbed depth data Through comparative analysis, the actual scour depth of the riverbed can be obtained. However, manual exploration is slow and dangerous, and divers cannot accurately obtain and express the damage of underwater struc...

AI Technical Summary

Problems solved by technology

However, manual exploration is slow and dangerous, and divers cannot accurately obtain and express the damage of underwater structures due to professional influence, and the errors in the data obtained by detection are relatively large

Ultrasonic detection of river bed section detection is affected by water quality, flow velocity and distribution of measuring points. Not only is the data accuracy low, but also it is impossible to collect multi-section river bed data at the same time. determination

[0003] At present, there is still a lack of effective solutions for the timely, accurate and effective collection of underwater structural damage data and riverbed scour data in China.
