河网区域特高压输变电线路大型承台高立柱模板选型分析

Analysis of High Column Template for Large Cap of UHV Transmission Lines in River Region

河网区域的特高压输变电线路建设中,大型承台的圆形高立柱工程施工必不可少,合理的模板选型对于圆形高立柱工程的顺利实施尤为关键。本文以湖北河网区域的特高压输电线路大型承台圆形高立柱工程为对象,从经济、轻便、可靠等角度出发,对定型钢模板、木模板、玻璃钢模板、波纹管模板和纸管模板等模板型式的适应性进行考察分析。分析结果表明:定型凹凸槽木模板和玻璃钢模板两种模板型式在各方面较能满足工程要求,可用于河网区域特高压输电线路大型承台的圆形高立柱工程施工。

The construction of large circular high column Caps is essential for the UHV transmission line construction in river area. So, the reasonable selection of the template is particularly critical. Taking the construction of large circular high column Caps for Hubei UHV transmission lines inriver area as an object, this paper analyzes the adaptability of the steel, wood, fiberglass, corrugated pipe, paper tube and other types template based on the economic, lightweight, reliable. The results show that point of view, given, templates, paper tube bellows template and of templates adaptability investigation and analysis. The results show that the concave-convex slot wood template andfiberglass template can meet the engineering requirements, which can be used for the constructionof UHV transmission lines in river area.
