Description

Technical Field

[0001] The present application relates to the field of detection equipment, and in particular to an automated pile foundation detection equipment. Background Art

[0002] Pile foundation testing refers to the testing and evaluation of pile foundations used in buildings or other projects to determine their quality and stability. As an important component that bears and transmits the load of buildings or other projects, the quality and stability of pile foundations play an important role in ensuring the safety and stability of the project. Therefore, pile foundation testing is of great significance.

[0003] The main methods for pile foundation testing include static load test, core drilling method, low strain method, high strain method, acoustic wave transmission method, etc. Among them, the low strain method is a testing method that uses low-energy transient or steady-state excitation to excite the pile top, measures the velocity time history curve or velocity admittance curve at the top of the pile, and determines the integrity of the pile body through wave theory analysis or frequency domain analysis.

[0004] At present, when the low-strain method is used, the staff mainly uses a handheld hammer to knock on the upper surface of the pile. However, due to the personal reasons of the staff during the knocking process, it is easy to cause the display curve of the detector to be abnormal, thereby affecting the test results.
