Pile Driving Analyzer PDA High Strain Pile Bearing Tester and Pile Integrity Tester

High strain Pile Driving Analyzer is a testing method for judging the vertical compressive bearing capacity of a single pile and the integrity of the pile body. In 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 and analyzed by wave theory .

The main detection methods of Pile Driving Analyzer are waveform fitting method, CAPWAPC method, Case method (Case method), wave equation method, etc.

The Pile Driving Analyzer (PDA) system is the most widely employed system for Dynamic Load Testing and Pile Driving Monitoring in the world. High Strain Dynamic Load Tests, also called PDA tests, assess the capacity of several piles in a single day. Pile Driving Analyzer systems also evaluate shaft integrity, driving stresses, and hammer energy when monitoring installation. If you plan to use your PDA to test non-driven piles make sure to read about that application as well.

High detection efficiency: By hitting the top of the pile with a heavy hammer, the pile-soil produces sufficient relative displacement, and the bearing capacity of the pile and the integrity of the pile quality can be quickly obtained. Compared with traditional methods such as static load tests, the detection speed is greatly improved, which can effectively shorten the engineering detection cycle.
Easy operation: The instruments and equipment are relatively simple, mainly including test instruments, hammering equipment, penetration measuring instruments, etc. The on-site operation process is relatively clear. Professionally trained technicians can quickly master the operation methods, which is convenient for carrying out detection work at different engineering sites.
Wide range of applications: It can be used for the detection of various types of pile foundations, including concrete piles, steel piles, etc., whether in the detection of pile foundations in construction projects, bridge projects, or port projects, and it can play a role in pile foundation detection in the fields of construction projects, bridge projects, and port projects. It also has good adaptability to pile foundations under different geological conditions.
Intuitive and accurate results: It can directly determine the ultimate bearing capacity of the pile, and through the stress wave theory analysis and processing of force and velocity time history curves, it can intuitively display the force condition of the pile body, the interaction between the pile and the soil, etc., and can accurately judge the integrity of the pile body, determine whether there are defects in the pile body, and the location and degree of the defects.
Strong data traceability: various data during the inspection process can be recorded in real time, including the time course curves of force and acceleration, etc. These data can be stored for a long time, which is convenient for subsequent query, analysis and comparison, and provides a reliable basis for the traceability and evaluation of engineering quality.
