Construction device for converting arch bridge from arch structure into cantilever structure
The invention discloses a construction device for converting an arch bridge from an arch structure into a cantilever structure. The truss type combined arch bridge system conversion device is installed on a solid web section, the cantilever structure stabilizing device is used for lifting an arch ring after the truss type combined arch bridge system is converted, and the truss type combined arch bridge cutting and dismantling sewage collecting device is hung at the bottom of the arch ring. By means of the construction device, after a bridge is cut and separated, relative displacement and left-right swing of the two independent cantilever truss systems can be avoided, the two independent cantilever truss systems can be lifted upwards, downward deflection and movement of the cantilever trusssystems are avoided, and a guarantee is provided for smooth implementation of follow-up dismantling work. The sewage generated in the cutting process can be prevented from being discharged into a water source below.
本发明公开了一种将拱桥由拱式结构转换为悬臂结构的施工装置，包括有安装在实腹段的桁式组合拱桥体系转换装置以及用于提拉住拱圈的桁式组合拱桥体系转换后悬臂结构稳定装置以及悬挂于拱圈底部的桁式组合拱桥切割拆除污水收集装置。本发明的装置可以避免桥梁切割分离后，两个单独的悬臂桁架体系出现相对位移和左右摆动，以及可以向上提拉住两个单独的悬臂桁架体系，避免悬臂桁架体系会有向下偏转、运动，为后续拆除工作的顺利实施提供保障。并且可以避免切割过程中产生的污水排放至下方的水源中。
