Dynamic Pile Testing Equipment High Strain Dynamic Pile Load Testing
High strain dynamic pile load testing is a method of testing deep foundations to obtain information about their capacity and integrity, and in some cases, to monitor their installation.It is a detection method to determine the vertical compressive capacity of a single pile and the integrity of the pile body. During the experiment, a heavy hammer is used to impact the pile top, and the velocity and force time history curves of the pile top are measured, which are analyzed through the wave theory.
Application
1.Detect the high strain bearing capacity and integrity of foundation piles
2.Monitor the stress of the precast piles during the driving
3.Low strain reflected wave method of foundation piles
