If the pile body is entirely buried in soil, and the bottom surface of the cap is in contact with the soil, it is called low-cap pile foundation. If the upper part of the pile is exposed to the ground and the bottom of the cap is above the ground, it is called high-cap pile foundation. Building pile foundation is usually low-cap pile foundation. Pile foundation is widely used in high-rise buildings. Due to the large difference in construction technology and the complexity of stratum variation, defects such as shrinkage, expansion, mud inclusion, segregation and broken pile may occur in the pile body during construction. Of course, mechanical excavation and collision after construction can also cause defects in the shallow pile body. The existence of pile body defects can change the normal working characteristics of the pile foundation, thereby posing a potential danger to the foundation. Evaluating the integrity of the pile body through acceptance testing is essential to ensure the safety of the foundation.
