提高预制箱梁施工质量的措施

在西汉高速公路07A标线的箱梁预制施工中，根据桥梁线型及桥梁所处位置，采用调整曲线悬臂、优化隔板连接和三角垫层控制等工艺，以保证预制箱梁的施工质量。实践表明上述工艺既提高了箱梁的施工质量，也缩短了后续工序的衔接时间，能有效地降低工程成本。

Measures to Improve Construction Quality of Precast Box Girder

In the prefabricating construction of 07A bid box girder for Xihan expressway,according to the bridge linear and location,adjusting the curve cantilever,optimizing the connection of clapboards,and controlling the triangle cushion are adopted to assure construction quality of box girders.Practice shows that the technology can improve construction quality,shorten the convergence time with the follow-up process,and reduce the project cost effectively.
