Pile top uniform stress conversion system of pile group foundation

The utility model discloses a pile top uniform stress conversion system of a pile group foundation, which is composed of at least four layers of profile steel, each layer comprises at least three pieces of profile steel, each layer of profile steel is orthogonally superposed, the uppermost layer of profile steel is used for supporting an upper structure load, and the lowermost layer of profile steel is arranged on the pile top of a pile group. The structure is convenient to construct, the section steel is orthogonally stacked layer by layer on the pile top of the pile group foundation to support an upper structure, and the section steel is finally and uniformly distributed to each pile top through continuous conversion and distribution of support reaction force between layers, so that the problem that a pier stud bearing platform cannot be made due to limitation of conditions such as clearance is solved, and the construction efficiency is improved. The pile group foundation directly bears the upper load; and
