Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building detection equipment, in particular to a pile hole sediment thickness detection device. BACKGROUND

[0002] The pile hole sediment thickness refers to the thickness of the sediment left by sedimentation or hole collapse during drilling and hole cleaning, which is not taken away by the circulating mud. In the construction of cast-in-place piles, the thickness of the sediment not only affects the exertion of the end resistance, but also affects the exertion value of the side resistance. Therefore, a detection device is needed to detect the thickness of the sediment to ensure the stability of the cast-in-place pile.

[0003] The existing detection device usually uses a measuring needle to measure the sediment thickness of the pile hole. The measuring needle is placed in the pile hole and inserted into the bottom of the sediment using a rope. After being pulled up, a measuring cake is hung on the sediment layer using the same rope. The difference between the two data is the sediment thickness. The rope is pulled twice, which is time-consuming and laborious to operate, and the work efficiency is low. When the measuring cake is pulled up again, it will touch the pile hole wall again, which will cause the soil residue to fall into the pile hole again, resulting in a large error in the measurement result.
