Prestressed constructional column structure suitable for reinforcing stone arch bridge pier body and construction method
The invention provides a prestressed constructional column structure suitable for reinforcing a stone arch bridge pier body, which comprises a plurality of reinforced concrete constructional columns arranged in the pier body, the constructional columns in all directions are connected into a whole through crown beam structures and straining beam structures, and a prestressed tendon structure is arranged in each constructional column; the prestressing tendon structure extends upwards to the top of the top beam structure and extends downwards to the bearing platform, and then prestress is applied to the constructional column; the longitudinal reinforced concrete top beam connects the constructional columns into a whole in the longitudinal bridge direction, and cantilevers are formed at the two ends of the longitudinal reinforced concrete top beam. The transverse reinforced concrete top beam connects the constructional columns into a whole in the transverse bridge direction, and the two ends of the transverse reinforced concrete top beam are flush with the edges of the constructional columns. The stone arch bridge pier body is reinforced through the prestress constructional column structure, the shear strength of the pier body can be improved, under the impact effect of water flow, the adverse effect of high horizontal force formed by the water flow on the root of the pier body is avoided, the integrity of the stone arch bridge is enhanced, and the bearing capacity of the stone arch bridge is improved.
本发明创造提供了一种适用于石拱桥墩身加固的预应力构造柱结构，包括墩身内部布置的若干钢筋混凝土构造柱，各方向构造柱均通过冠梁结构和系梁结构连接成整体，并在每一构造柱内部均设有预应力束结构；预应力束结构向上延伸至冠梁结构顶部，向下延伸至承台，进而对构造柱施加预应力；纵向钢筋混凝土冠梁将构造柱沿纵桥向连接成整体，其两端部形成悬臂；横向钢筋混凝土冠梁将构造柱沿横桥向连接成整体，其两端部与构造柱边缘平齐。本发明创造通过预应力构造柱结构对石拱桥墩身进行加固，可提高墩身的抗剪强度，在水流冲击作用下，避免水流形成的较强水平力对墩身根部的不利影响，增强石拱桥整体性，提高石拱桥自身承载力。
