箱梁是桥梁工程中梁的一种。与现浇箱梁不同,预制箱梁施工周期较短,衔接较为简便,但其也有不足之处。本文论述的主要内容就是30m预制箱梁的常见质量问题,包括:麻面、水波纹,解析其质量控制的几个要点,对桥梁工程建设具有重要意义。 Box girder is a beam bridge project. Different from the cast-in-place box girder, the construction period of the prefabricated box girder is shorter and the connection is relatively simple, but it also has some shortcomings. The main content of this article is the common quality problems of 30m prefabricated box girder, including: pony surface and water ripple, and some key points of quality control are analyzed, which is of great significance to the bridge construction.
