Electric power grounding pile for electric power engineering installation

The utility model relates to an electric power grounding pile for electric power engineering installation, which comprises a pile body, hollow pipes are arranged in the pile body, and push rod assemblies are symmetrically arranged in the hollow pipes; each limiting assembly comprises an insertion rod, a guide rod, a first compression spring and sliding plates fixed to the two sides of the insertion rod, a second compression spring is arranged at the top end of the first clamping plate, a second compression spring is fixedly arranged at the bottom of the second clamping plate, an inflation branch pipe is arranged between the hollow pipes, and the air inlet end of the inflation main pipe penetrates through the interior of the top cover. High-pressure gas only needs to be injected into the hollow pipes through the gas inlet end of the inflation main pipe, the push rod assemblies in the hollow pipes begin to be far away from each other under pushing of the high-pressure gas, the first clamping plate and the secon
