Abstract

The invention discloses a multi-beam detection system for an underwater concealed work. The multi-beam detection system for the underwater concealed work is installed on a test ship, and comprises a computer, a GPS module, a multi-beam system, a three-dimensional scanner, a first sound velocity meter and a second sound velocity meter; the GPS module, the multi-beam system, the three-dimensional scanner, the first sound velocity meter and the second sound velocity meter are separately connected with the computer; the GPS module performs positioning; the multi-beam system performs water depth measurement; the three-dimensional scanner detects the slit width of a caisson; the first sound velocity meter measures a sound velocity profile of a measurement area in a layering manner at different times; the second sound velocity meter measures the surface sound velocity of an energy converter of the multi-beam system; on one hand, the computer performs positioning and navigation according to positioning information; and, on the other hand, the computer processes received information, and forms a water depth chart and an underwater terrain model chart digitally. The construction quality of the underwater concealed work can be accurately judged.

Description

technical field

[0001] The invention relates to a multi-beam detection system and a detection method. Background technique

[0002] With the development of water transportation engineering construction, ports and waterways are becoming larger and deeper. Due to the unique construction location of the water transport engineering construction project, it is determined that the basic part of the construction should be carried out underwater, especially the underwater foundation part of the gravity wharf, caisson installation and other construction, which is not only the most difficult part of the wharf project, but also the most difficult part of the wharf project. The most important part is directly related to the foundation stability and structural safety of waterway engineering.

[0003] Underwater construction is a difficult part of the project. The construction of the underwater project of the port is often affected by various factors such as ocean waves, currents, etc. T...
