Horizontal bearing structure erected on inclined leg surface

The utility model discloses a horizontal bearing structure erected on an inclined leg surface, an inclined leg is connected between a box girder of a bridge and a bearing platform corresponding to the bottom, and the horizontal bearing structure comprises a supporting underframe for supporting and positioning the bottom and a plurality of bearing surface constructs for horizontally supporting. The supporting bottom frame is laid on the inclined leg face of the inclined leg, the bottom side end, transversely extending along the inclined leg face, of the supporting bottom frame abuts against the bearing platform for limiting, and the opposite top side end of the supporting bottom frame is close to the joint of the box girder and the inclined leg. The multiple bearing face constructs are regularly arranged on the supporting bottom frame so as to construct multiple layers of horizontal bearing faces which are sequentially arranged at intervals in the longitudinal direction of inclined extending of the inclined le
