Description

Technical Field

[0002] Since the 1980s, with the expansion of China's infrastructure scale, the demand for pile foundation projects has increased sharply. The dynamic testing method has gradually become popular due to its advantages of speed and low cost. By analyzing the dynamic response at the pile top (such as the characteristics of reflected waves and stress wave propagation), it can judge the quality and bearing capacity of the pile body and has become an important supplement to static load tests. Currently, most pile dynamic testers are realized by a detection instrument, a detection head, and a percussion hammer. During detection, it is necessary to manually attach the detection head to the foundation pile, and then manually strike the foundation pile to collect data. During this process, there are manual percussion errors, and it is necessary for someone to always hold the detection head for detection, which is very inconvenient and the accuracy of the data cannot be guaranteed. The present invention aims to design a pile dynamic tester for water conservancy projects optimized based on cloud data, which can be quickly installed on the foundation pile, then automatically test the foundation pile, and can also compare with cloud data, change the detection position, and eliminate abnormal situations.

[0036] As a further embodiment, a wireless control unit 6 is provided on the connecting housing 4. The wireless control unit 6 can be in signal connection with an external terminal and control the driving elements in this device. This is prior art and its principle will not be outlined.

[0037] As a further embodiment, an arc-shaped groove 7 is provided at the lower end inside the sliding housing 1, and two rolling balls 41 are provided at the upper end of the arc-shaped groove 7.

[0038] As a further embodiment, four first through holes 36 are formed in the sliding ring 35, the outer wall of the detection head 34 is slidably and sealingly connected to the inner wall of the retaining ring 38, and four second through holes 40 are formed in the retaining ring 38.

[0039] As a further embodiment, a rubber sealing head 39 is provided in each second through hole 40, and the rubber sealing head 39 can be opened under pressure. The rubber sealing head is in a four-petal fitting shape, which is tightly closed when not under pressure and opens when under pressure.

[0040] When the device in this embodiment is performing detection, a certain amount of coupling agent is first injected into the limit sleeve 33, and then the arc-shaped grooves 7 of the two arc-shaped shells 1 are clamped on the upper edge of the pile to be detected. The second driving motor 5 is started, and the tapes 8 on the two second reel wheels 28 are tightened, so that the inlets of the two arc-shaped shells 1 are on the upper edge of the pile. During this process, the sliding rod 14 slides in the sliding outer shell 13. Then, the driving cylinder 30 is controlled to lower the connecting pipe 31, thereby driving the limit sleeve 33 to move downward together. After the limit sleeve 33 contacts the upper end surface of the pile, under the drive of the driving cylinder 30, the connecting pipe 31 continues to move downward, driving the detection head 34 to move downward and extend out in the retaining ring 38. At the same time, due to its relatively fast downward pressure speed, the coupling agent is sprayed out from the second through hole 40 through the rubber sealing head 40 via the sliding ring 35. Before the detection head 34 contacts the surface of the pile, the coupling agent is spread over the contact position, and the range of the coupling agent is restricted by the limit sleeve 33 to avoid waste.

[0041] Subsequently, the third driving motor 19 is controlled to release the limit, and the hammer 17 strikes the surface of the pile under the action of gravity. The detection head 34 detects the signal and transmits it to the external terminal through the signal transmitter 32.

[0042] If the detected waveform is normal or conforms to the normal defect situation, the two first driving motors 9 are controlled to drive the first gear 11 to rotate, thereby driving the two sliders 10 to slide in the same direction on both sides respectively, realizing the translation of the connecting member. Then, the above steps are repeated to collect two more groups of data. Each group is detected three times, and the detection data is more accurate.

[0043] When an abnormal waveform diagram is detected through cloud data comparison, the two sliders 10 are controlled to move to two different ends of the arc-shaped shell 1, and the sliders 10 are controlled to start detecting from the ends. The sliders 10 are controlled to slide and rotate in the same direction, realizing the rotation of the connecting member, so as to detect multiple groups of data at more different positions on the pile plane, record and report the abnormal situation of this pile.

[0044] The above are only the preferred embodiments of the present application. Although the present application has been disclosed above with preferred embodiments, it is not intended to limit the present application. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present application, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of the present application.
