The specification requires that end-bearing piles should not be larger than five centimeters and friction piles should not be larger than ten centimeters. Sediment detection is a key factor in ensuring the quality of foundation piles. At present, this step is often ignored during construction due to the lack of simple measuring equipment. The thickness of the sediment cannot be effectively controlled and the quality of the foundation piles cannot be guaranteed. In order to solve this problem, a detection device that is easy to make and simple to operate is particularly important.

At this time, the tip of the steel bar 6 does not exceed the bottom of the round plate base 1. The measured hole depth is L1.

The hole depth is measured again as L2. At this time, the thickness of the sediment is L2-L1. This method can be used to complete a relatively accurate measurement of the thickness of the sediment.
