The method is suitable for truss type photovoltaic support with large terrain height difference

The utility model discloses a truss type photovoltaic support suitable for a large terrain height difference, which comprises a support truss and a plurality of upright posts, the support truss is arranged at the tops of the upright posts, and a foundation pile is arranged below each upright post; the bottom of each stand column is connected with a pre-buried pipe through a height adjusting mechanism, the lower portion of each pre-buried pipe is pre-buried in the foundation pile, and a grouting pile is arranged in each pre-buried pipe. And at least one stand column is formed by detachably connecting a plurality of sections of splicing columns. The stand column is formed by splicing the multiple sections of splicing columns in the area with the large terrain height difference and the position with the low terrain height difference, the number of the sections of the splicing columns is determined according to the actually-needed height, the elevation of the foundation pile is kept unchanged, the stand column co
