【摘要】：以1 000kV淮南—南京—上海特高压输变电工程苏通过江通道大跨越可研设计方案为背景,介绍了跨越塔整体式钢管-钢筋笼和钢筋笼导向下滑结构设计方案,并对2套结构设计方案对应的钢管配筋施工工艺进行了真型试验验证,比较了两套施工工艺的技术操作可行性、安全性、安装精度、人员机具组织、施工效率,为后续结构设计方案选择和组塔技术方案制定提供了科学依据。试验结果表明:整体式钢管-钢筋笼方案安装时间较长,工效较低,连接安装质量欠佳;钢筋笼导向下滑方案安装工艺安装时间较短,工效较高,但钢筋笼整体顺利就位连接存在不确定性,需进一步优化结构设计。最后,从施工安装角度出发,本文对跨越塔内配钢筋笼主管结构设计方案提出了一些优化改进建议。
[Abstract]:Based on the design scheme of 1 000kV Huainan Nanjing Shanghai UHV transmission and transformation project Sutong crossing the crossing river channel, the design scheme of the slide structure of the whole steel pipe reinforcement cage and the reinforcement cage is introduced, and the actual test verification of the steel pipe matching technology corresponding to the 2 sets of structural design schemes is tested and compared. The technical operation feasibility, safety, installation accuracy, personnel equipment organization and construction efficiency of the two sets of construction techniques provide scientific basis for the selection of the subsequent structural design scheme and the formulation of the technical scheme for the group tower. The experimental results show that the integral type steel tube reinforcement cage has a long time, low efficiency and poor connection installation quality; The installation process of the downward slide scheme is shorter and the efficiency is high, but the overall smooth connection of the reinforcement cage is uncertain, and the structural design needs to be further optimized. Finally, from the angle of construction and installation, this paper puts forward some optimization suggestions on the design scheme for the structure of steel cage in charge of the tower.
