Low Strain Pile Integrity Tester for Foundation Analysis

Product Description

Low Strain Integrity Testing Pile Dynamic Analyzer Foundation Pile Non Destructive Integrity Testing Instrument Low Strain Pile Analyzer Pit Pile Echo Tester


Usage
The P8100 Foundation Pile Dynamic Detector is used to assess the integrity of concrete pile and identify the extent and location of the pile defects by using reflected wave method.

It can be used for testing bored concrete pile and hammer pile and also for testing the structures with exposed top surface such as pillars.



PIT Pile Integrity Tester Wire Foundation Pile Echo Tester Reflective Wave Pile Testing Instrument
Basic Principle
Hit the top of pile with testing hammer to produce stress wave, and the wave may reflect when it meets defect (pile bottom, crack, or soil middle layer) while it run downward through the concrete. The probe placed on the top of the pile receives the reflected signal. The instrument digitally processes the signal in order to judge the quality of foundation pile. According to the time interval between the arrival of the direct wave and first reflected wave, or time interval between the two continuous reflected waves, the depth of foundation pile can be determined by the following equation: D= VP×TP/2 (D - depth of foundation pile, VP - compression wave speed, TP- compression wave spread time)

Features

Two-channel design can measure reflected wave speed accurately, and it can collect reflected wave at two places.

True 24 bit A/D data acquisition provides high resolution waveform avoiding the noise and signal distortion.

1MHz high-speed data acquisition makes the minimum sampling time resolution reach 1us, providing more useful information and contributing to the discovery of shallow defects.

High Brightness and TFT colorful LCD screen.

Store waveform images for each tested pile.

New wavelet processing method can effectively judge the integrity of foundation pile in complex situation.

Water-proof; protection class reaches IP65.

This refers to the application of a dynamic force (dynamic load) on the top of the pile, which can be either a transient impact force or a steady state excitation force. The pile-soil system generates a dynamic response to the dynamic force. Dynamic response signals (e.g. displacement, velocity, acceleration signals) are measured at the top of the pile using sensors with different functions, and the structural integrity of the pile is determined by time-domain analysis or transfer function analysis of the signals. For the same pile, the three waveform curves formed by three hammer blows should be basically the same in form, amplitude and phase, and the collected data should be considered qualified.
