Abstract

The invention relates to the technical field of building detection, in particular to a hole bottom sediment high-accuracy detection device and method. The device comprises a mounting base, a scale rope is mounted on the mounting base, and a mounting frame is fixed to the tail end of the scale rope; a first measuring assembly used for measuring the hole depth after hole forming and a second measuring assembly used for measuring the hole depth before pouring are connected to the mounting frame, and the second measuring assembly wraps the first measuring assembly. A driving assembly used for driving the first measuring assembly to move in the axis direction of the second measuring assembly until the first measuring assembly is exposed out of the second measuring assembly is arranged between the mounting frame and the second measuring assembly. The problems that an existing hole bottom sediment detection device is simple in structure and prone to deviating from the center position of a drill hole in the measurement process, and the accuracy of a measurement result is affected are solved. The method has the effect of improving the accuracy of the measurement result of the hole bottom sediment detection device.

Description

technical field [0001] The present application relates to the technical field of building detection, in particular to a high-accuracy detection device and method for bottom sediment. Background technique [0002] At present, sediment refers to the sediment left by sedimentation or hole collapse during drilling and hole cleaning, which is not taken away by the circulating mud, and the sediment particles are relatively coarse. [0003] The existence of sediment at the bottom of the hole will affect the bearing capacity of the solidified concrete pile. Therefore, it is necessary to measure the thickness of the sediment at the bottom of the hole to determine whether it is within the appropriate range. If it exceeds the range, the sediment needs to be cleaned. [0004] The sediment thickness is the layer height of this layer of sediment. The sediment thickness is measured by the difference between the hole depth measured after the bored pile is formed and the hole depth measured...
