Product Introductions

In the process of deepwater channel regulation and laying construction, in order to ensure the quality of laying, a certain overlap width needs to be reserved between adjacent laying bodies. However, during the sinking process, due to the influence of gravity and various environmental factors, there will be a contraction in the width direction of the row after it sinks. Usually, in order to meet the design overlap width, it is only possible to increase the overlap width on the water surface to ensure that the design overlap width requirements are met after the row is implanted. 

Expanding the overlap width on the water surface has increased the ineffective area of paving, resulting in an increase in construction costs and a decrease in construction efficiency. There is currently no efficient and accurate monitoring method for the overlap width of underwater drainage, mainly relying on divers to explore underwater, which is time-consuming and laborious. It is urgent to use advanced technology to construct an online monitoring system for the overlap width of underwater drainage.

Using side scan sonar to carry out detection technology for the overlap width of sinking and drainage, constructing an underwater sonar image acquisition device for deepwater sinking and drainage construction process, researching underwater sonar imaging denoising and pseudo color enhancement methods, laying the foundation for further realizing automatic discrimination of the overlap quality of underwater sinking and drainage.
