Construction method of bridge prestress continuous box girder
The invention provides a construction method of a bridge prestress continuous box girder. The construction method comprises the steps that a foundation is treated; erecting and pre-pressing of a bracket is carried out; a template is manufactured and installed; reinforcing steel bars, corrugated pipes and steel strands are installed; concrete construction is carried out, and box girder tensioning is carried out. The construction process provided by the invention is effectively simplified, original numerous influence factors are eliminated, the advantages of few reinforcing bars and light structure are achieved, the overall quality of subsequent bridges is guaranteed, a good market prospect is achieved, and the construction method is suitable for popularization and application.
本发明提供了一种桥梁预应力连续箱梁的施工方法，方法包括地基处理；支架搭设及预压；制作模板并安装；安装钢筋、波纹管以及钢绞线；混凝土施工；箱梁张拉。本发明提供的施工工艺得到有效简化，消除了原先众多影响因素，充分发挥了配筋少且结构轻盈的优点，保障了后续桥梁的整体质量，具有良好的市场前景，适于推广使用。
