Product Description

Foundation Pile Dynamic Tester
1. Field of use
The apparatus is used to assess the integrality of concrete pile and determine the length of foundation pile. P810 is used for testing perfusion pile and hummer pile. It is also used for testing the exposed top wall construction such as pillar.
Testing length and concrete characters of pile
It can be used in precasting concrete pile (steel pipe), cast-in-place concrete pile and wood pile
Determine the abnormal situation of foundation pile, such as pile length, collapsed area, crack, cut expend or contract and poor quality concrete area.
2. Basic tenets
Hit the top of pile with testing hammer, to produce compression wave, the wave may reflect when it meets defect (pile bottom, crack, or soil middle layer) whilst it permeates downward through the concrete. The probe, placed on the top of the pile, receives the reflected signal. The apparatus 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).
