Root type micro pile foundation suitable for mountain electric power

The invention relates to the technical field of micro piles, in particular to a root type micro pile foundation suitable for mountain electric power, comprising: a hollow outer cylinder, the hollow outer cylinder is formed by sequentially splicing and fixing a plurality of steel pipes end to end, and the surface of the hollow outer cylinder is provided with a permeation notch; the connecting piece is arranged to be in an inverted V shape, and one side edge of the connecting piece is vertical. The reinforcement cage comprises vertical steel bars and annular steel bars, and the reinforcement cage rotates to push the connecting pieces and the sealing baffles to horizontally slide through the vertical steel bars and open the permeation notches; the device has the beneficial effects that the permeation notches are formed in the surface of the hollow outer cylinder, the slidable sealing baffles cover the inner sides of the permeation notches, the connecting pieces are fixed to the inner walls of the sealing baffles
