Technical Field

[0001] The present invention relates to the technical field of ultrasonic imaging, and in particular to a distribution system. Background Art

[0002] Construction joints refer to the joint surface formed between successively poured concrete. In the actual construction process, due to the limitations of construction technology and water flow arrangement, concrete cannot be poured continuously, resulting in the formation of construction joints between successively poured concrete.

[0003] At present, in order to detect construction joints, when ultrasonic imaging is used in the prior art, an ultrasonic transmitting probe is generally set on one side of the construction joint in the defective area with the construction joint defect, and an ultrasonic receiving probe is set on the other side of the construction joint to detect and obtain the radiation parameters of the defective area with the construction joint defect.

[0004] In order to detect the existence of construction joints, before imaging the construction joints, it is necessary to first detect the intact area without construction joints to obtain the radiation parameters of the intact area; after obtaining the radiation parameters of the defective area, the image of the construction joint area is obtained by comparing the two radiation parameters.

[0005] The existing method requires setting the positions of the ultrasonic transmitter and receiver twice. The first time, the transmitter is set on one side of the construction joint and the receiver is set on the other side of the construction joint to obtain the ray parameters of the defective area; the second time, the transmitter and the receiver are set on the same side of the construction joint to obtain the ray parameters of the intact area. This method is time-consuming and labor-intensive, and has low imaging efficiency. Summary of the invention

[0028] Specifically, in one implementation, see Figure 1 , and also includes a predetermined space 1 for accommodating the concrete.

[0029] Specifically, in one implementation, see Figure 1 The predetermined space 1 is a rectangular space having a first short side, a first long side, a second short side and a second long side.
