盖梁支架在高架桥施工中的应用——以余杭区崇贤至老余杭连接线(高架)工程为例

The Application of Bent Cap Support in Viaduct Construction——Taking Chongxian-Old Yuhang Connecting Line (Viaduct) Project in Yuhang District as an Example Concrete Application of Cover Beam Support in Viaduct Construction

城市高架桥的建设有助于缓解交通拥堵,提高城市的发展水平。高架桥工程中,盖梁的建设可减少墩身的数量,属于高架桥的常见结构。支架是盖梁施工中的重要装置,合理搭设支架对提高施工质量有重要意义。因此,需加强对盖梁支架施工技术的探讨。文章结合具体工程实例,阐述了高架桥盖梁支架设计方案,对现浇盖梁支架结构形式进行了分析,并详细探讨了盖梁支架体系关键施工技术要点,以降低桥梁施工安全风险,提高盖梁支架施工效率,保障桥梁工程的整体施工质量。

The construction of urban viaducts helps to alleviate traffic congestion and improve the level of urban development. In the viaduct project, the construction of the bent cap can reduce the number of piers, which is a common structure of the viaduct. The support is an important device in the construction of the bent cap, and the reasonable erection of the support is of great significance to improve the construction quality. Therefore, it is necessary to strengthen the discussion on the construction technology of the bent cap support. Combined with specific engineering examples,this paper expounds the design scheme of viaduct bent cap support, analyzes the structural form of cast-in-place bent cap support, and discusses in detail the key construction technical points of bent cap support system, so as to reduce the safety risk of bridge construction, improve the construction efficiency of bent cap support, and ensure the overall construction quality of bridge engineering.
