Description

Technical Field

[0001] The utility model relates to the field of building accessories, in particular to an engineering foundation pile detection and fixing device for engineering detection. Background Art

[0002] Pile foundation testing can test the concrete strength, pile length, pile bottom sediment thickness, etc. of the pile body to ensure that the pile quality meets the design requirements. This helps to avoid pile foundation defects caused by construction quality problems and improve the overall quality of the building. Through testing, we can understand the impact of construction technology on pile foundation quality and provide data support for optimizing construction technology. At the same time, we can also monitor the construction technology to ensure that various parameters are controlled within a reasonable range during the construction process.

[0003] In the prior art, when inspecting pile foundations, the inspection device is fixed in the soil layer area around the pipe mouth at the top of the pile foundation. The weight of the device presses down on the soil layer area at the pipe mouth, which often causes the soil layer at the pipe mouth of the pile body to collapse into the pipe. Inspection can only be carried out after artificial prefabrication of the reinforcement mold in advance, and it is impossible to reinforce the pipe mouth of the pile foundation during inspection.
