[0040] In this embodiment: a data transmission line 394 is provided at the top side of the access sleeve 391 , and a connection mechanism 4 is provided at one end of the data transmission line 394 .

[0050] In this embodiment: the knocking mechanism 2 includes a knocking detection bracket 21 installed on the back side of the analysis box 11, and connecting rods 22 are provided on both sides of the top of the knocking detection bracket 21, and a knocking rod 23 is clamped in the middle of the connecting rod 22;

[0053] When used specifically:

[0054] Step 1: Construction project supervision pile foundation percussion vibration detection;

[0055] In this stage, the concave bracket 31 is used and then supported by the concave bracket 31 and then hinged to the side of the deflection base 34. After the deflection of the adjustment roller 36 is used, the specific position of the deflection base 34 is coordinated, and then the rotation of the extension adjustment handle 33 is manually coordinated. Under the slot limit of the adjustment roller 36 and the concave slot 37 at this stage, the front and rear displacement of the bottom access roller 38 is further controlled. In this stage, the front and rear displacement of the detection base 393 is controlled by the rod body extension state of the connecting rod 392. In this process, the middle connecting rod 392 and the detection base 393 are fitted with the building to be detected;

[0056] Step 2: Remove the striking mechanism 2;

[0057] In this step, the knock detection brackets 21 on both sides need to be opened and then the knock structure of the knock rod 23 is removed from the surface, and finally the knock rod 23 is manually held and ready, and any elastic knock head 25 is placed on the ground where the construction project needs to be monitored;

[0058] Step 3: Turn on the control terminal 1 to power on the excitation detection controller for internal detection;

[0059] In this stage, the two adjustment knobs 13 need to be adjusted continuously (the operating power of the ultrasonic excitation detector is limited by the adjustment knobs and the damping power amplifier);

[0060] The secondary process observation display panel 12 can be viewed intuitively;

[0061] At this time, the user holds the knocking rod 23 and knocks the elastic knocking head 25 hard, which generates vibration after contacting the building. This vibration will directly cause the regional building to resonate, and this resonance will directly feedback the ripple attenuation, which will be detected by the detection base 393 after decreasing. After that, it will be transmitted along the area of ​​the connecting sleeve 392 and then connected based on the area of ​​the access roller 38. Finally, the data will be connected by one end of the data transmission line 394. After the connection, the ultrasonic excitation detector used for ultrasonic detection and analysis will realize signal transmission around the access head 42 and the connecting base 43 after processing the data, and form signal ripples according to the waveform attenuation. This ripple will finally be gradually fed back on the surface of the display panel 12, and the analysis status of the adjustment knobs 13 on both sides and the corresponding analysis box 11 will be used to further complete the board presentation of the specified display panel 12.

[0062] The data feedback can then allow humans to better observe and perceive the internal structure of a building during the construction phase.
