[0039] 1. The speed of ultrasonic wave propagation is directly related to the density of concrete. The faster the concrete is, the higher the sound speed is. On the contrary, the slower the concrete is, the lower the sound speed is. Moreover, the ultrasonic wave propagation speed in concrete is related to the strength of concrete, and the strength of concrete is closely related to the age of concrete. Therefore, the ultrasonic wave propagation speed in concrete is a function of the age of concrete. 2. There is no strict scientific mathematical formula for the ultrasonic wave propagation speed in concrete and the strength of concrete. Some mathematical formulas or relationship equations used now are summarized by experts and scholars through a large amount of test data. Therefore, the relationship equations obtained by different researchers in different places are different. Under normal circumstances, ultrasonic testing does not provide concrete strength data. 3. When the curing age is short, ultrasonic testing is carried out. During ultrasonic testing, it is often found that the wave velocity is low and the wave amplitude is small within 3m of the pile top. This is because the concrete below 3m from the pile top is compacted by the gravity of the upper concrete, and its density is higher than that of the pile top, while the concrete within 3m from the pile top is subject to less external force. 4. The acoustic detection tube is buried close to the inside of the steel cage. When the neck is not retracted to the inside of the steel cage, the sound wave reaches the receiving transducer from the transmitting transducer without penetrating the defective concrete. This kind of neck is not easy to detect by ultrasonic testing. 5. For some cast-in-place piles, there are holes or honeycomb holes in the pile body, and the defective part is in the water-saturated sand layer. Due to the infiltration of water, groundwater enters the hole. When the sound wave penetrates the defect, the sound wave does not penetrate the concrete and air, but the concrete and water.

[0040] The multi-channel ultrasonic pile detector component 3 is the MC-6360 multi-channel ultrasonic pile detector, which is specially developed for detecting the integrity of piles by the sound wave transmission method. It can expand the functions of ultrasonic rebound comprehensive method strength measurement, loose area and void detection and ultrasonic crack depth detection. The multi-channel self-circulation function can complete the test of 6 sections of concrete cast-in-place piles at one time. Compared with single-section or one-transmit and two-receive instruments, it greatly improves the detection efficiency. It adopts a radial transducer for both transmission and reception, and cooperates with pre-amplification technology to perfectly solve the industry problem of unclear and difficult to interpret the first wave. It is small in size (diameter 25mm, length 180mm), with an effective concrete test span of more than 8 meters, and adopts an iterative interpretation algorithm to improve the accuracy of automatic interpretation of the first wave under complex conditions. It has an industrial-grade ARM processor with a main frequency of up to 1GHz, a new ARM Cortex A8 processor, and a deeply customized Windows CE 6.0 real-time operating system. It enters the test system in 15 seconds after startup. The system runs stably and the power can be turned off directly after saving the data.

[0041] The method for using the vibration monitoring device for concrete vibration quality comprises the following steps:

[0042] Step 1: Install the whole assembly. Place the fixed support assembly 1 on the roadside where the concrete is to be vibrated. Align the mobile crawler assembly 4 and the concrete vibration ultrasonic detection assembly 5 above the concrete to be vibrated. Then place the multi-channel ultrasonic pile detector assembly 3 on the support platform 101 surface of the fixed support assembly 1. Pass the detection line 308 through the detection line anti-friction assembly 2, the detection line passing round block 108 and the anti-friction passing line rotating cylinder 109. Insert the sound wave acquisition data transmission head 309 connected at one end into the data transmission connection cylinder 504.

[0043] Step 2: Use the mobile crawler assembly 4 to start the drive motor 402 to drive the crawler 407 to move the mobile external plate 403 and the external fixed plate 404 at one end up and down so that the connected vibrating rod 501 is inserted into the concrete to be vibrated downward to perform vibration and ultrasonic testing;

[0044] Step three, use the multi-channel ultrasonic pile detector component 3 to transmit the ultrasonic data of the concrete vibration ultrasonic detection component 5 when vibration and ultrasonic wave are carried out simultaneously to the detector body 301 in real time, which can be viewed on the display panel 304, and the operation panel 303 can be used to adjust and correct the data of the ultrasonic wave released by the ultrasonic detector 502.

[0045] The working principle of the technical solution provided by the present invention is as follows:

[0046] First, by setting up a multi-channel ultrasonic pile detector component 3, the concrete vibration ultrasonic detection component 5 can be connected to collect the vibration frequency and ultrasonic data in real time when the vibration rod 501 and the ultrasonic detector 502 release ultrasonic waves during vibration, and the operation panel and internal software are used to adjust the data and calibrate the device. In addition, the support platform 101 in the structure of the fixed bracket component 1 is placed on the roadside, and the L-shaped operating panel 104 is placed on the top of the concrete. The simple bracket can be used to work stably, and the cost is low. The mobile crawler component uses a sliding track to move the concrete vibration ultrasonic detection component 5 installed on one side up and down to insert and pull out the concrete. The overall device reduces the cost and has a simple structure. Then, the active slide rail 401 and the track 407 set inside the driven slide rail 406 in the mobile track assembly 4 structure are powered by the drive motor 402 that rotates the track 407 to move the mobile external plate 403 and the external fixed plate 404 installed on one side up and down. An I-shaped base is set at the bottom of the active slide rail 401, which can also be used in other scenarios. The base is fixed to the ground with fixing parts to perform mobile work. In addition, the detection line anti-friction component 2 and the detection line passing circle 108 can wrap and pass the detection line 308 inside to prevent the line from being too long and falling onto the concrete below during operation. The structure uses a softer rubber material to prevent the detection line 308 from excessive friction and damaging the surface.

[0047] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
