Description

Technical Field

[0002] After the pile foundation hole is excavated, multiple tests are required to meet the construction requirements and ensure the overall quality of the construction. The flatness of the hole wall is an important item in the inspection to ensure the stability of the pile foundation after installation.

[0003] In the prior art, the method of detecting pile foundation holes mostly uses a crane or a winch to hoist the detection instrument into the pile foundation hole.

In addition, the pile foundation holes will have some differences in size according to the construction requirements. It is difficult for one detection equipment to be fully applicable. Multiple detection instruments of different specifications are required for detection, which increases the cost. In addition, during the detection process, it is not convenient to effectively record the flatness of the hole walls of different depths, which has a certain impact on the later pouring construction.
