Foundation Pile Dynamic Detector Reflected Wave Method Two Channel

For more details , please check the following specification document .Field of Use The 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.

• ◆ 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.
• ◆Basic Principle: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= V P ×T P /2 (D - depth of foundation pile, V P – compression wave speed, T P － 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 .High Brightness and TFT colorful LCD screen.
• ◆Features: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.Store waveform images for each tested pile. Water-proof; protection class reaches IP65.
• ◆Features:New wavelet processing method can effectively judge the integrity of foundation pile in complex situation. Key and touch screen
