Background
Pile foundation engineering is generally divided into two types of end-bearing piles and friction piles, the two types of piles have index requirements on the thickness of hole bottom sediments before concrete pouring, and the thickness of the end-bearing pile is not larger than 100mm; the friction type pile should not be larger than 300mm. The thickness of the sediment affects the exertion of end resistance and the exertion value of side resistance, so that the control of the sediment thickness of the pile foundation engineering is important. However, the thickness of the sediment is often detected by the way that field constructors measure the drill rod and use the measuring rope to hang the heavy hammer, but when the downward resultant force of the hung heavy hammer at the intersection of the underground water and the sediment surface is not changed greatly, the measurer often cannot accurately measure the elevation of the sediment surface.
