Abstract
A method for constructing a fixed monitoring pile for a mining area with a high phreatic water level includes: S1: prefabricating a pile foundation body, where the pile foundation body has a columnar structure, and a plurality of extension connection ports are provided at an outer side and a bottom of the pile foundation body; and S2: digging a foundation pit at a designated monitoring point; combining the pile foundation body with an extension body to form a fixed monitoring pile; placing the fixed monitoring pile into the foundation pit, such that a bottom extension body and a side extension body are inserted into the pit foundation; and backfilling and compacting. The method increases the affinity between the fixed monitoring pile and a loose layer and strengthens the fixed monitoring pile to prevent it from loosening, thereby improving measurement accuracy.
