What are the pile foundation detection methods At present, the commonly used pile foundation detection methods at home and abroad are as follows: ① core drilling method: because the planning load of large straight bored pile is generally large, there are many difficulties in using static pile test method, so the common geological drilling rig is used to drill core samples along the length direction of the pile body, and the quality of the pile is determined through the investigation and test of the core sample. But this approach can only [2019-03-08] View details -
