Construction Technology of Cap Beam for Central Single-pillar Pier of Urban Road

既有通车道路施工大悬臂盖梁,采用常规盖梁施工支架需要足够的施工空间,常规钢筋施工方案高空作业多,安全风险大,采用本文提出的落地钢管+斜拉塔架的支架形式有效解决了施工空间不足的问题,钢筋笼整体吊装大大提高了施工效率,降低了安全风险,加强了施工质量。

Existing road construction with large cantilever cover beams,the use of conventional cover beam construction brackets requires sufficient construction space.Conventional steel construction schemes involve many high-altitude operations and high safety risks.The floor steel pipe+cable-stayed tower bracket form proposed in this article is adopted.Effectively solve the problem of insufficient construction space.The overall hoisting of steel cages greatly improves construction efficiency,reduces safety risks,and enhances construction quality.
