[0002] In engineering construction, the pile foundation construction quality is directly related to the safety and durability of structure, and the hole forming quality detection of the cast-in-place pile as a common foundation form is particularly important. The prior art usually detects and analyzes the actual size data of the pile hole, including the hole diameter, hole depth, perpendicularity and hole bottom sediment thickness, to determine whether the drilling hole meets the relevant technical standards and design requirements of the state and industry. These detection data not only can reflect the overall quality of the hole forming process, but also provide reliable basis for subsequent pile foundation construction and bearing capacity evaluation.

[0003] In practical application, engineering technicians often need to comprehensively analyze the multiple measured data in the trial hole forming process, and further evaluate the stability of the hole wall by comparing the change trend of the hole diameter, hole depth and sediment thickness. In this process, abnormal conditions need to be found out in time, and construction parameters need to be adjusted to ensure that engineering accidents caused by hole wall collapse or other safety hazards are avoided during drilling and pile foundation construction.

The detector needs to be manually pulled to open the umbrella-shaped structure, which may cause difficulty in operation of the umbrella frame during opening, and there is a certain safety hazard. Such a detector not only reduces the detection efficiency, but also may pose a potential threat to the personal safety of the operator.

[0005] Therefore, how to improve the automation level of the umbrella-shaped detector, improve its opening reliability, and ensure the detection accuracy while protecting the safety of the operator, has become a problem to be solved in the current pile foundation detection technology.
