Description

Technical Field

[0001] The invention belongs to the technical field of underwater laying construction, and in particular relates to underwater laying sonar scanning equipment in shallow water conditions. Background Art

[0002] Underwater paving is a riverbed protection measure. When laying the paving, the overlap width between the upper and lower paving is the key to affecting the paving quality. If the overlap width is lower than the design requirements, it will cause water to wash in the overlapping gap area, causing bottom sand to leak at the gap, making the riverbed protection fail. If the overlap width is higher than the design requirements, it will cause waste and make the project cost too high. During the paving process, sonar is usually used to monitor the quality of the paving in real time.

[0003] In the prior art, for example, the authorization announcement number CN103744084B discloses a real-time monitoring and detection method for underwater laying quality. When using sonar for monitoring, it is necessary to control the distance between the sonar and the target object. If the distance is too close, the reflected signal may become very strong, resulting in signal saturation, affecting the accuracy and reliability of detection. If the distance is too far, the sound waves will be subject to more interference during propagation, such as attenuation, refraction and scattering, etc., all of which will affect the accuracy and resolution of monitoring.

[0004] The current underwater sonar scanning equipment is not easy to adjust the water depth, especially in shallow water conditions, which can easily cause the sonar to be too close to the target and affect the accuracy of monitoring.
