Reinforcing construction method of solid-web masonry arch bridge
The invention relates to the technical field of solid-web masonry arch bridge reinforcement, in particular to a reinforcing construction method of a solid-web masonry arch bridge. The method comprisesthe steps: A, a pouring formwork is erected below the bottom of an original arch ring of an arch bridge, and a reinforcement layer pouring area is formed between the pouring formwork and the bottom of the original arch ring; B, a pouring through hole is formed in the bridge deck of the arch bridge, extends downwards along the bridge deck of the arch bridge, sequentially penetrates through a pavement layer, an arch crown filler and the original arch ring of the arch bridge and communicates with the reinforcing layer pouring area; c, premixed concrete is poured into the reinforcing layer pouring area through the pouring through hole till the reinforcing layer pouring area is filled with the concrete, pouring is stopped, and the concrete forms a reinforcing layer in the reinforcing layer pouring area; and D, after the strength of the reinforcing layer reaches the preset strength, the pouring formwork is dismounted. According to the reinforcing construction method of the solid-web masonryarch bridge, the quality of the reinforcing layer can be improved, the thickness of the reinforcing layer is reduced, and the reinforcing construction process is simplified.
本发明涉及实腹式圬工拱桥加固技术领域，具体涉及一种实腹式圬工拱桥的加固施工方法，包括：步骤A：在拱桥的原拱圈底部下方搭设浇筑模板，使得浇筑模板与原拱圈底部之间形成加固层浇筑区；步骤B：在拱桥的桥面上开设浇筑通孔，所述浇筑通孔沿拱桥的桥面向下延伸且依次贯穿拱桥的铺装层、拱顶填料以及原拱圈并与加固层浇筑区连通；步骤C：通过所述浇筑通孔向加固层浇筑区浇筑预拌的混凝土，直至混凝土填充满加固层浇筑区后停止浇筑，混凝土在加固层浇筑区形成加固层；步骤D：待加固层的强度达到预设强度后拆除所述浇筑模板。本发明的实腹式圬工拱桥加固施工方法，能够提高加固层质量、减小加固层厚度、简化加固施工流程。
