A Chinese patent application, CN212835543U, discloses a pile foundation monitoring device for civil engineering. The device comprises a retaining ring, multiple sliders, and pressure sensors. When the pile foundation deflects, the displacement of the retaining ring drives the sliders, activating the corresponding sensors. These sensors then trigger an alarm, alerting on-site personnel of the abnormal pile foundation condition.

[0004] Foundation piles are buried underground to bear the load of the building and transfer it to the foundation soil to increase the stability and bearing capacity of the building. For the convenience of monitoring, a device for monitoring the bearing capacity of the foundation piles is usually installed on the part of the foundation piles located on the ground to achieve real-time monitoring of the foundation piles, structural safety assessment and early warning prompts. Generally, the device is fixed on the top of the foundation piles, but when it rains outside, the foundation piles are prone to displacement and settlement. When the top of the foundation piles tilts, the entire device will also tilt, and the overall center of gravity of the device will shift.
