The instrument is suitable for testing the vertical compressive bearing capacity and pile integrity. Monitoring the pile body stress and hammering energy transfer ratio during driving of precast piles provides a basis for selecting pile driving parameters and pile length.
For large-diameter expanded bottom piles and large-diameter cast-in-place piles whose estimated Q - s curve has the characteristics of gentle variation, this method should not be used for vertical compressive bearing capacity testing.
When testing the vertical compressive bearing capacity of cast-in-place piles, it is necessary to have on site testing experience and reliable comparison and verification data under similar conditions in the region.
