In dense urban environments, shield machines often need to pass through areas where various pre-arranged pile foundations exist. In this case, the accurate location and depth information of the pile foundation is crucial to avoid risks, optimize the excavation path, and protect the existing underground structure.

[0003] For example, Chinese patent 202321256480.9 discloses a pile foundation depth measurement device for piling, which includes a measuring component and a fixing component.
