External prestress reinforced and repaired concrete cover beam

The utility model relates to a concrete cover beam reinforced and repaired by external prestressing. The concrete cover beam comprises a cover beam body, a pier column, a bearing platform, a newly-added foundation, a reinforced steel pipe column, a hanging type construction platform, longitudinal prestressing tendons and a transverse prestressing device. The utility model has the beneficial effects that the original bridge is reinforced by adopting the newly added foundation and the reinforced steel pipe column, and the overall stability of the bridge is improved through a temporary support span reduction technology; the hanging type construction platform is adopted to provide a construction platform for reinforcing the bent cap, so that the safety of the construction operation is improved; local transverse prestress and longitudinal prestress are combined to reinforce the cover beam, and the overall strength of the cover beam structure is improved. 本实用新型涉及一种体外预应力加固修复混凝土盖梁，包括：盖梁、墩柱、承台、新增基础、加固钢管柱、吊挂式施工平台、纵向预应力
