Building foundation pit steel pipe support built-in prestress axial force device connecting structure

The invention discloses a building foundation pit steel pipe support built-in prestress axial force device connecting structure. The building foundation pit steel pipe support built-in prestress axial force device connecting structure comprises a supporting steel pipe, a first connecting piece is arranged on one side of the supporting steel pipe, a cushioning pad is arranged on the side, away from the supporting steel pipe, of the first connecting piece, and a second connecting piece is arranged on the side, away from the first connecting piece, of the cushioning pad. The building foundation pit steel pipe support built-in prestress axial force device connecting structure has the beneficial effects that the fixing effect is achieved through connection of the first connecting piece and the second connecting piece; damping is carried out on the connecting position through the design of the cushioning pad, assimilation damping is carried out on axial force, and the effect of protecting the axial force device is
