Lifting structure and lifting method for water-area-crossing concrete bridge
The invention relates to a lifting structure and a lifting method for a cross-water-area concrete bridge, the lifting structure and the lifting method are used for lifting a pier of the bridge, the pier comprises an upper segment and a lower segment, the section of each segment is provided with a first meshing tooth structure, the lifting structure comprises a lengthened concrete block, and the upper end face and the lower end face of the lengthened concrete block are each provided with a plurality of shear-resistant tooth blocks; second meshing tooth structures meshed with the first meshing tooth structures are respectively formed on the upper end surface of the lengthened concrete block and the anti-shearing tooth blocks on the lengthened concrete block as well as on the lower end surface of the lengthened concrete block and the anti-shearing tooth blocks on the lengthened concrete block; lengthened steel bars which vertically penetrate through the lengthened concrete blocks and are used for being connected with reserved steel bars of the upper segment and the lower segment of the pier. The second meshing tooth structures are meshed with the first meshing tooth structures on the sections of the upper section and the lower section of the pier, so that the joint is difficult to displace in the horizontal direction, the lifting structure is tightly combined with the original pier, and the requirements of the lifting structure for shear capacity and bearing capacity are met.
本申请涉及一种跨水域混凝土桥梁的抬高结构及抬高方法，其用于对所述桥梁的桥墩进行抬高，所述桥墩包括上下两个节段，且所述节段断面上具有第一啮齿结构，其包括：接长混凝土块，其上下两个端面均设有多个抗剪齿块，且所述接长混凝土块上端面与其上的抗剪齿块，以及所述接长混凝土块下端面与上的抗剪齿块，各自形成用于与所述第一啮齿结构相啮合的第二啮齿结构；接长钢筋，其竖向穿设所述接长混凝土块，并用于与所述桥墩上下两个节段的预留钢筋连接。第二啮齿结构与桥墩的上下两个节段的断面上的第一啮齿结构相啮合，使连接处难以在水平方向产生位移，并且使该抬高结构与原来的桥墩之间结合紧密，满足抬高结构的抗剪能力和承载能力的要求。
