摘要
上海S26公路入城段工程采用桥墩预制拼装设计,主要是在墩柱顶预留钢筋,盖梁底预埋套筒,拼装后通过灌浆固定连接。重点介绍预制盖梁整体安装施工的质量控制点,根据预制盖梁整体安装工序,研究盖梁整体安装施工技术关键点,分析最易出现质量问题的薄弱环节,因此预制盖梁吊装工艺、盖梁安装标高、坐浆等施工工序成为质量控制重点,也是预制盖梁整体安装施工技术关键内容。
The construction of Shanghai S26 Road into the city adopts the design of prefabricated bridge pier assembly,which is mainly to reserve steel bar on the top of pier column,pre-embedded sleeve on the bottom of coping,and fixed connection through grouting after assembling.This paper introduces the quality control points of overall installation of precast coping,according to the whole installation process, researches the key points of integral installation technology of precast coping,analyzes the weak links of quality problems,so the hoisting process of precast coping,installation elevation of precast coping and pulping and so on become the focal points of quality control,which are also the key content of integral installation technology of precast coping.
