Reconstruction structure and construction method of bridge bearing platform
The invention discloses a reconstruction structure of a bridge bearing platform. The reconstruction structure comprises additional foundation structures, wherein the additional foundation structures are respectively arranged on two sides of a bearing platform body structure; each additional foundation structure comprises an additional pile position base, additional pile positions, and an additional base cushion layer positioned under the additional pile position base; steel bars of the bearing platform body structure are fixedly connected with steel bars of the additional pile position bases; the distance between every two adjacent corresponding additional pile positions is 1-2 times of that between every two adjacent corresponding original pile positions; the upper parts of the additional pile position bases are flush with the upper part of the bearing platform body structure; the bottoms of the additional pile position bases are flush with or lower than the bottom of the bearing platform body structure. The reconstruction scheme of the bearing platform, adopted by the reconstruction structure disclosed by the invention, adopts a non-migrating manner, so that the phenomena of time consumption, labor consumption, large construction difficulties and the like, caused by secondary construction, are avoided, the cost is reduced, and the construction efficiency is effectively improved. The reconstruction structure disclosed by the invention adopts a pile overlapping structure which is artful in overlapping design, so that the reconstructed bearing platform structure is firm. A construction method adopted by the reconstruction structure disclosed by the invention has the characteristics of being simple to operate and high in efficiency.
