Sonar detecting bracket and caisson seam measuring method

Abstract

The invention discloses a sonar detecting bracket and a caisson seam measuring method. The main structure of the bracket is trapezoidal. A three-dimensional sonar host is fixed inside the bracket bodycavity. The opening end of the trapezium guarantees a large contacting surface between the bracket and the caisson, so that the stability of detection, the emission range of sonar, and the accuracy of detection data are guaranteed. The depth of the sonar head is mastered by a sounder. The weight and position of the floating material on the bracket are used to meet requirements of different waterflow conditions and working postures. The caisson seam measuring method which is based on three-dimensional sonar measurement technology can adjust corresponding water depth detecting points accordingto the actual detecting conditions to realize visual, fast, and low-cost non-destructive detection of caisson seams. The caisson seam measuring method can qualitatively and quantitatively and accurately measure the width of the caisson seam, provides basis for quickly judging the construction quality of caisson engineering, can be widely used in the actual engineering inspection of caisson mounting, and has strong practicability and wide applicability.

Description

technical field [0001] The invention relates to a support and a method for measuring joints, in particular to a sonar detection support and a method for measuring the joints of caissons, and belongs to the technical field of underwater concealed engineering detection in engineering. 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 waterway engineering construction project, it is determined that the basic part of the construction should be carried out underwater, especially the installation of the underwater caisson of the gravity wharf is the most difficult and most important part of the wharf project. Involves the foundation stability and structural safety of the wharf.
