The piling construction can be divided into pore-forming & into piling. So the foundation quality inspection can be also divided into two aspects: the quality control of pore-forming & piling-forming, The pore-forming is the first step of cast-in-place bored pile engineering. As the drilling operation is completed underground & in the water, so it is difficult to control the quality, Any
