Description

Technical Field

[0001] The invention relates to the technical field of pile foundation detection, and in particular to a pile foundation detection device using an acoustic wave transmission method. Background Art

[0002] Pile foundation testing technology is an engineering test method used to evaluate the structural integrity and bearing capacity of pile foundations. Acoustic wave transmission pile foundation testing equipment is a device that uses pile foundation testing technology to detect pile foundations. It emits sound waves and receives transmission signals inside the pile body, analyzes the propagation speed, attenuation and reflection of the sound waves in the pile body, and thus determines whether the pile body has defects such as cracks, cavities, corrosion, etc.

[0003] After searching, the applicant found that a Chinese patent disclosed "a pile foundation detection device" with a publication (announcement) number of "CN110565703A". This patent mainly sets a first crossbeam, and the rectangular slider of the first crossbeam is slidably engaged with the second crossbeam body, so that the overall mechanism can change the spacing of the connecting sleeves according to the size of the pile foundation, which greatly increases the scope of application and reduces the volume of the overall mechanism, providing convenience for storage. However, traditional pile foundation detection equipment using the acoustic wave transmission method usually requires two workers to use it together. One worker is required to hold the equipment in front for detection, and the other worker checks the detection results, resulting in low practicality of the equipment and increased difficulty in using the equipment. In addition, traditional pile foundation detection equipment using the acoustic wave transmission method cannot adjust the height, so it cannot be used for pile foundations of high heights. The worker needs to manually adjust the position, which reduces the comfort level during the use of the equipment and greatly reduces the use effect of the equipment. Summary of the invention
