大跨径连续梁预应力施工技术要点分析

Analysis on Key Points of Prestressed Construction Technology for Long-Span Continuous Beam

结合具体工程项目,介绍工程基本概况,从摩阻试验、下料与编束、管道布置、钢束穿束、预应力施加、压浆及封锚等方面,详细研究分析了大跨径连续梁预应力关键施工技术的施工技术要点。

Combined with the concrete project,the basic situation of the project is introduced,and the key construction technology points of the prestressed key construction technology of long-span continuous beam are studied and analyzed in detail from the aspects of friction test,blanking and bunching,pipeline arrangement,steel bunching,prestressing application,grouting and anchor sealing.
