Corrugated steel web continuous rigid frame bridge construction method
The invention provides a corrugated steel web continuous rigid frame bridge construction method, and relates to the field of bridge construction. The corrugated steel web continuous rigid frame bridge construction method comprises the steps that the triangular brackets are installed on the main piers; and a hanging basket is arranged on the middle span. Prefabricated formworks needed by pouring of a straight line section and a closure section of a side span are installed on the hanging basket, and a lower main beam of the hanging basket is supported by a triangular bracket. And a corrugated steel web is mounted on the bottom die of the prefabricated template. And pouring of a straight line section and a closure section of the side span is conducted in the prefabricated formwork. And after the side span straight line section and the closure section are formed, the triangular bracket and the hanging basket are disassembled. According to the corrugated steel web continuous rigid frame bridge construction method, the straight line section and the closure section of the side span are constructed at the same time, and the construction period is short.
本申请提供了一种波形钢腹板连续刚构桥施工方法，涉及桥梁修建领域。波形钢腹板连续刚构桥施工方法包括在主墩上安装三角托架；在中跨上安装挂篮。在挂篮上安装边跨的直线段及合龙段浇筑所需的预制模板，用三角托架支撑挂篮的下主梁。在预制模板的底模上安装波形钢腹板。在预制模板内进行边跨的直线段及合龙段的浇筑。边跨直线段及合龙段成型后，拆除三角托架和挂篮。该波形钢腹板连续刚构桥施工方法同时施工边跨的直线段和合龙段，施工周期较短。
