Description

Technical Field

[0001] This utility model relates to the field of engineering testing, and in particular to a portable pile foundation strain testing box. Background Technology

[0002] Pipe piles are the foundation of a building structure and directly affect its stability. To ensure the building maintains good stability during subsequent use, strain testing must be performed on the pipe piles after construction is completed.

[0003] By inspecting the foundation piles, defects in the piles can be prevented from affecting the stability of the building. The low-strain pile testing method is suitable for detecting the integrity of concrete piles and determining the degree and location of pile defects. It is currently a widely used pile quality inspection method in China. The low-strain pile foundation tester uses the reflected wave method to detect the integrity of the foundation pile. A dynamic force is applied to the top of the pile. The dynamic force can be a transient impact force or a steady-state excitation force. Sensors with different functions are used to measure the dynamic response signal at the top of the pile. By analyzing the time domain or transfer function of the signal, the integrity of the pile structure can be determined. Utility Model Content
