摘要
以甘肃省兰州市某公路工程建设项目桥梁工程上部结构施工为例,对双向六车道一级公路桥梁上部为宽幅钢波纹腹板-混凝土组合箱梁双钢梁的箱间预制桥面板安装施工工况进行分析,主要包括工艺原理、施工准备、测量放样、预制桥面板运输、电动机械提梁机起吊、预制桥面板安装架设等内容.针对该种施工条件,通过专门设计制作的轮胎式电动机械提梁机,将预制桥面板快速安装至钢波纹腹板-混凝土组合箱梁双钢箱梁箱之间预定位置上.这提高了施工安全性和稳定性,加快了施工进度和生产效率,减少了燃油消耗和车辆尾气的排放,对减少施工成本、提升安全环保文明施工水平具有良好的效用.
Abstract
Taking the construction of the superstructure of the bridge project of a highway construction project in Lan-zhou City,Gansu Province as an example,this paper analyzes the installation and construction conditions of prefabricated bridge decks among the boxes of the two-way six-lane first-class highway bridge,the upper part of which is a double steel girder with the wide steel-corrugated web-concrete composite box girder,mainly including the process principle,construction preparation,surveying and setting out,transportation of prefabricated bridge decks,lifting of electric me-chanical girder cranes,installation and erection of prefabricated bridge decks,etc.For this construction condition,a spe-cially designed and manufactured tire-typed electric mechanical girder crane is used to quickly install prefabricated bridge decks to the predetermined position among the boxes of the double steel box girder with the steel-corrugated web-concrete composite box girder,which improves the safety and stability of construction,accelerates the construction progress and production efficiency,reduces fuel consumption and vehicle exhaust emissions,and has good effects on re-ducing construction costs and improving the level of safe,environmentally-friendly and civilized construction.
