摘要:
［目的］钢桥墩是悬挂式单轨交通系统的重要组成部分，其制造精度直接决定了轨道梁的架设安装，从而影响列车平稳运行，有必要对其进行研究。［方法］以武汉光谷生态大走廊旅游配套设施——旅游专线一期工程项目为依托，针对悬挂式单轨交通钢桥墩T形结构特性，结合钢桥墩制造精度设计要求进行工艺研究；分析了单轨钢桥墩制造过程中的难点，并对其钢盖梁制造方案进行比选；系统阐述了悬挂式单轨钢桥墩的制造工艺及精度控制方法。［结果及结论］通过钢桥墩实际生产制造与现场轨道梁架设安装，能够有效控制钢盖梁耳板间距（0～2mm）以及悬臂中心距立柱中心线距离（-2～2mm）；钢桥墩总拼成形后，其左盖梁销轴定位点到钢立柱底部中心点的连线与右盖梁销轴定位点到钢立柱底部中心点的连线之间的距离误差≤3mm，耳板中心与立柱中心标高误差≤2mm，满足钢桥墩总拼制作要求，实现了对钢桥墩制造精度的控制。
Abstracts:
［Objective］ Manufacturing accuracy of the steel bridge pier, which is an important part of the suspended monorail transit system, determines the erection and installation of track beams, thereby affecting the train smooth running. Therefore, it is necessary to conduct research on it. ［Method］ Based on the Tourism Special Line Phase I Project, a supporting facility for Wuhan Optics Valley Ecological Corridor Tourism, the process research is conducted in response to the T-shaped structural characteristics of steel bridge piers for suspended monorail transit and combining the design requirements for the manufacturing accuracy of steel bridge piers. The difficulties in the manufacturing process of monorail steel bridge piers are analyzed, and the manufacturing schemes for the steel cap beams are compared and selected. Moreover, the manufacturing process and accuracy control methods of suspended monorail steel bridge piers are systematically expounded. ［Result & Conclusion］ Through the actual manufacturing of steel bridge piers and the on-site erection and installation of track beams, the distance between the lug plates of the steel cap beams (0-2 mm) and the distance from the cantilever center to the column central line (-2-2 mm) can be effectively controlled. After the overall assembly and formation of the steel bridge piers, the distance error between the line connecting the positioning point of the left cap beam pin axis to the center point at the steel column bottom, and the line connecting the positioning point of the right cap beam pin axis to the center point at the steel column bottom is ≤3 mm, and the elevation error between the center of the lug plate and the center of the column is ≤2 mm, meeting the requirements for the overall assembly and production of steel bridge piers, and realizing the control over the manufacturing accuracy of steel bridge piers.
