[0002] During deep-sea steel pile construction, especially during installation of jacket pile legs, the steel pile end passage inspection and related condition detection face many technical problems, which seriously affect construction efficiency, safety and cost control. The traditional passage inspection method relies on a drill rod centralizer, and needs to install and remove an ultra-long drill rod of 62 meters. The whole process takes 8-10 hours, which is low in efficiency and greatly affects the construction period.

[0003] In terms of obstacle detection, there may be buckling deformation, rocks and other obstacles in the steel pile, which are difficult to accurately locate. In the past, divers have used a handheld camera for detection, but the camera has poor stability and cannot obtain clear images, which brings great difficulty to the identification and judgment of obstacles.

[0004] For the deformation area of the steel pile end, the traditional method can only be qualitatively observed, and lacks accurate size evaluation means, and cannot provide accurate reference data for subsequent construction. In terms of sonar measurement, the fixed sonar frame has obvious defects. Since the sonar box is fixed, it cannot be rotated by a steel wire to change the angle, and can only be recycled to adjust the angle. Each measurement can only obtain data of limited 3 angles, and the data quantity is seriously insufficient, which affects the measurement accuracy and the reliability of the results.

[0005] Therefore, it is urgent to design a jacket steel pile end passage inspection device to solve the above-mentioned problems. SUMMARY
