Abstract

The utility model provides a reference pier. The reference pier is used for placing a settlement observation device and comprises a foundation pit and a corrugated pipe, the corrugated pipe extends into the foundation pit and makes contact with the bottom wall of the foundation pit, concrete is arranged in the corrugated pipe, and the settlement observation device is arranged in the portion, exposed out of the ground, of the corrugated pipe. And the settlement observation device is embedded in the concrete. According to the settlement observation device, the corrugated pipe is buried in the foundation pit, the settlement observation device is placed in the mode that the corrugated pipe is filled with the concrete, the engineering design requirements of settlement observation under various geological conditions can be met, and the settlement observation device has the advantages of being simple in structure, low in cost and high in construction efficiency.
