Detection apparatus for foundation engineering construction sediment thickness
Technical Field

Background
The sediment refers to sediment left by sediment or hole collapse in the process of drilling and cleaning the hole and not taken away by the circulating mud. Generally of coarser particle size, the thickness of the sediment, i.e. the height of the layer of sediment. It is also believed that the sludge thickness is the difference between the hole depth measured as soon as the hole is cleared and the hole depth measured after the downcomer. Before concrete is poured, the thickness index of the sediment at the bottom of the hole is specified, and the length of the end bearing type pile is not more than 50 mm; the counter friction type pile should not be larger than 100 mm. Firstly, the construction experience of the cast-in-place pile for many years is provided; second, in recent years, it has been shown from the results of pile tests with different sediment thicknesses at the pile bottom that the sediment thickness affects not only the performance of the end resistance but also the performance of the side resistance. This is one of the important discoveries of the load-bearing characteristics of cast-in-place piles in recent years, and the original specification is revised on the friction pile sediment thickness of 300 mm. Measuring the length of the drilling tool which is put below the ground as the depth of the hole bottom, measuring the depth of the measuring rope as the depth of the top surface of the sediment, and taking the difference as the thickness of the sediment.
