Construction method for steel-concrete combined section of bridge
The invention relates to a construction method for a steel-concrete combined section of a bridge, which comprises the following steps of: assembling a steel structure of a steel splicing section of the steel-concrete combined section, and constructing a steel grid chamber of a concrete splicing section; after the steel structure and the steel geocell are pre-assembled, turning the axis of the steel structure and the steel geocell to be vertical, and making a pouring opening of the steel geocell face upwards; pouring concrete into the steel grid chamber from the pouring opening; and after the concrete reaches the preset strength, overall hoisting is conducted, splicing the concrete with the 0 # block, and completing the construction procedure of the steel-concrete combined section. According to the mode that pouring is conducted firstly and then hoisting is conducted, the construction quality of the steel-concrete combined section is improved, and the quality of a concrete splicing section formed after concrete pouring is guaranteed. During pouring, the axis of the steel-concrete combined section is converted into the vertical direction, so that concrete in the steel grid chamber of the steel-concrete combined section is convenient to pour and vibrate, the compactness of the concrete in the steel grid chamber of the steel-concrete combined section is increased, the cohesive force between the concrete and the rear bearing plate, the PBL shear keys and steel plates in the steel grid chamber is increased, and meanwhile the shear keys and prestressed elements are protected.
本发明涉及一种桥梁钢混结合段的施工方法，拼装钢混结合段的钢拼接段的钢结构，构造混凝土拼接段的钢格室；将钢结构与钢格室预拼装之后，将其轴线转为竖向，使钢格室的浇筑开口朝上；从浇筑开口向钢格室内浇筑混凝土；在混凝土达到预设强度之后，整体吊装并且与0#块进行拼接，以完成钢混结合段的施工工序。本申请先浇筑后吊装的方式，提高了钢混结合段的施工质量，使得浇筑混凝土后形成的混凝土拼接段质量得到保证。在浇筑时将钢混结合段的轴线转为竖向，使钢混结合段钢格室内的混凝土便于浇筑和振捣，增加了钢混结合段钢格室内的混凝土的密实度，以及混凝土与后承压板、PBL剪力键、钢格室内钢板之间的粘结力，同时保护了剪力键和预应力原件。
