摘要
国内某快速路工程是杭州亚运会的配套设施。现依托背景为快速路的220 kV高压线下大体积曲线现浇连续梁,上方穿既有220 kV青里、青九线,交叉角度分别为67°、48°,电力线在这两处,分别距离原地面的最小高度为23.5 m、23.92 m。针对220 kV高压线下大体积曲线现浇连续梁,提出了一套完整的施工方案及流程,对其现浇梁钢管贝雷支架结构体系进行结构设计与计算,确保ZXH146-149大体积曲线现浇连续梁满足施工安全,为后续类似高压线下现浇梁施工提供参考借鉴。
A domestic expressway project is the supporting facilities of Hangzhou Asian Games.This paper relies on the background of the expressway 220 kV high voltage line large volume curve cast-in-place continuous beam,cast-in-place continuous beam above the existing 220 kV Qingli,Qingjiu line,crossing Angle is 67°and 48°.The power line in two places respectively from the original ground minimum height of 23.5 m and 23.92 m.In this paper,a complete construction scheme and process are proposed for the large volume curve cast-in-place continuous beam under 220 kV high voltage line,and the structural design and calculation are carried out for the structure system of the cast-in-place beam steel pipe Beret support.Ensure that the ZXH146-149 large volume curve cast-in-place continuous beam meets the construction safety,and provide reference for the subsequent construction of similar cast-in-place beam under high pressure line.
