Reinforcing construction method for hinged part of arch bridge
The invention provides a reinforcing construction method for a hinged part of an arch bridge, and relates to the technical field of bridge repair. The method comprises the following steps that a water stop material is injected into a construction joint of a hinged part of existing arch ring concrete; water spots and loose parts on the existing arch ring concrete are removed, and the surface of the arch ring concrete is ground to be rough; a rubber waterstop is pasted on the bottom face of the existing arch ring concrete; reinforcing steel bars are bound, a formwork is installed, and a section-increasing high-strength grouting material is poured at the bottom of the existing arch ring concrete; after the newly-poured section-enlarged high-strength grouting material reaches the design strength, a filling groove is formed in a construction joint of the hinged part of the section-enlarged high-strength grouting material; a water stop material is injected into the upper portion of the filling groove, and a consolidation material is injected into the lower portion of the filling groove, the method can effectively reinforce the hinge portion of the existing arch ring concrete, the hinge portion can still keep the hinge capacity, in addition, the waterproof capacity of the hinge portion can be improved, and a certain degree of waterproof reserve is reserved.
本发明提供了一种拱桥铰接部位加固施工方法，涉及桥梁修复技术领域。它包括以下步骤：在既有拱圈混凝土的铰接部位施工缝内注入止水材料；清除既有拱圈混凝土上的水渍及疏松部位，并将其表面打磨粗糙；在既有拱圈混凝土的底面上粘贴橡胶止水带；绑扎钢筋，安装模板，在既有拱圈混凝土的底部浇筑增大截面高强灌浆料；待新浇筑的增大截面高强灌浆料达到设计强度后，在增大截面高强灌浆料的铰接部位施工缝内开设填充槽；在填充槽的上部注入止水材料，在填充槽的下部注入固结材料，此方法能够有效加固既有拱圈混凝土的铰接部位，使铰接部位仍然能够保持其铰接能力，此外，还能够提高铰接部位的防水能力，并且保留一定程度的防水储备。
