Energy-consuming rebar-attached unbonded post-tensioning prestressed concrete filled double-wall steel tube prefabricated assembly bridge pier
The invention discloses an energy-consuming rebar-attached unbonded post-tensioning prestressed concrete filled double-wall steel tube prefabricated assembly bridge pier comprising a bearing platform, a prefabricated assembly bridge pier and a cover beam. The energy-consuming rebar-attached unbonded post-tensioning prestressed concrete filled double-wall steel tube prefabricated assembly bridge pier is characterized in that the prefabricated assembly bridge pier is a concrete filled double-wall steel tube prefabricated assembly bridge pier; the prefabricated assembly bridge pier comprises an outer steel tube, an inner steel tube and filled concrete; the end faces of the top and the bottom of the outer steel tube and the inner steel tube are respectively connected by four steel sheets; fiber-reinforced mortar layers are arranged between the top face of the bearing platform and the end face of the prefabricated assembly bridge pier and between the bottom face of the cover beam and the end face of the prefabricated assembly bridge pier; the bearing platform, the prefabricated assembly bridge pier and the cover beam are assembled integrally by a prestressed tension device; and four common ribbed energy-consuming rebars are respectively between the top face of the bearing platform and the end face of the prefabricated assembly bridge pier and between the bottom face of the cover beam and the end face of the prefabricated assembly bridge pier. The energy-consuming rebar-attached unbonded post-tensioning prestressed concrete fill double-wall steel tube prefabricated assembly bridge pier has the advantages that the construction quality is improved, the construction speed is increased, operational quantity of the scene is reduced, and impact on environment is alleviated. The energy-consuming rebars provide attached energy-consuming capacity for the bridge pier, and the displacement demand of the bridge pier under the action of horizontal load, such as earthquake can be controlled and reduced.
