Parallel Seismic Testing Device for Foundation Piles Length

Parallel Seismic Testing Device for Foundation Piles Length

The Parallel Seismic Testing method is to use a hammer (force bar) to strike the pile top surface (or the pile cap, pile cap and other superstructure connected with the pile top) in the vertical direction to generate the stress wave, and propagate downward along the pile body. when encountering the surrounding soil layer for transmission, sensors are placed in the holes drilled in advance beside the pile to receive the transmission wave signal, so as to read the wave time of different depths and draw the first break time A depth diagram. When the sensor is lower than the pile bottom, the sound velocity will change, and an inflection point will be displayed on the time depth map. The length of the pile can be inferred from the position where the slope of the straight line changes. The slopes of the two straight lines can be used to infer the average wave velocity of the pile body and the wave velocity of the bearing stratum at the pile bottom respectively.
