Background In the field of construction engineering, foundation piles are used as key foundation members for bearing the load of an upper structure, and the stability and the bearing capacity of the foundation piles are directly related to the safety of the whole structure. Traditional foundation piles mainly provide bearing capacity through friction force and end resistance between pile bodies and surrounding soil bodies. However, under the condition of soft soil foundations, complex geological conditions or bearing large horizontal loads (such as wind force and earthquake force), the problems of insufficient bearing capacity, overlarge lateral displacement and the like of the traditional foundation piles can occur, and engineering safety is affected. In order to improve the bearing capacity and stability of foundation piles, reinforcement methods such as pile head expansion, support disc arrangement or pile side grouting are commonly adopted in the prior art. However, these methods are often complicated to construct, have high cost, and the reinforcement effect is difficult to accurately control and monitor in real time. For example, after grouting reinforcement of the pile side, the diffusion range of the slurry and the strength uniformity of the reinforcement body are not easy to ensure, and the methods such as setting the support plate have high requirements on construction precision and limited adaptability. In addition, the monitoring of the health states of settlement, inclination and the like of the foundation pile in the long-term use process is also of great importance. The current common monitoring means (such as an external inclinometer, a settlement observation point and the like) generally belong to post-detection or point-type monitoring, and the settlement of foundation piles is difficult to accurately and directly monitor. The best opportunity for maintenance may be musted. Therefore, there is a need for a foundation pile device integrating efficient reinforcement and real-time monitoring, which can conveniently and reliably reinforce in the construction stage, and continuously and sensitively sense the settlement around the pile foundation during the service period, so as to improve the overall performance and safety of foundation pile engineering.
