Vertical cyclic loads will be applied to pull-out piles in situations such as groundwater level changes and sea level rise and fall. However, the clamps of today's pile foundation pull-out detection devices are prone to slipping, and cannot be adjusted according to the size of the pile foundation, which is not conducive to rapid detection of pile foundations of multiple sizes.
