Problems solved by technology
Therefore, the sediment is not always flat, and there may be a large slope, or there may be local protrusions and pits. The equipment is often placed obliquely on the surface of the sediment, so that the measured data has a large error, or the measured data is local data, not the overall average data of the sediment, which is not reliable

Description
technical field [0001] The invention relates to the technical field of engineering construction, in particular to a device and method for detecting the thickness of sediment at the bottom of a bored pile. Background technique [0002] Cast-in-place pile refers to the pile hole formed in the foundation soil by means of mechanical drilling, steel pipe excavation or manual excavation at the project site, and a steel cage and poured concrete are placed in it. Cast-in-place piles can be further divided into immersed cast-in-place piles, bored cast-in-place piles and excavated cast-in-place piles. [0003] Sediment refers to the sediment left by sedimentation or hole collapse in the process of drilling and cleaning, which is not carried away by the circulating mud, and is generally coarser particles. Therefore, the sediment is not always flat, there may be a large slope, or there may be local protrusions and pits. The equipment is often placed obliquely on the sediment surface, ...
