Hollow slab beam hinge joint water seepage repairing structure and method
The invention belongs to the field of bridge building repairing, and particularly discloses a hollow slab beam hinge joint water seepage repairing structure. Comprising hollow slab girders arranged side by side and hinge joint concrete transversely connected with the hollow slab girders, and a concrete pavement layer, a bridge floor waterproof layer and an asphalt pavement layer are sequentially arranged above the hollow slab girders from bottom to top. A disengaging gap exists between the top wall of the hollow slab beam and the concrete pavement layer, and an interface gap exists between the side wall of the hollow slab beam and the hinge joint concrete. A plurality of hole channels are drilled in the hinge joint concrete in the bridge length direction, glue injection needle heads used for injecting glue into the hole channels are embedded in the lower ends of the hole channels, and the glue injection needle heads are fixed to the bottom of a hinge joint through joint sealing mortar. The invention further discloses a hollow slab beam hinge joint water seepage repairing method. Construction is conducted at the bridge bottom, and construction is more convenient; in addition, the method can be used for repairing void gaps and interface gaps, and can also be used for repairing fine gaps in hinge joint concrete, so that the overall waterproof performance of a bridge is improved.
本发明属于桥梁建筑修复领域，具体公开了一种空心板梁铰缝渗水修补结构。包括并排放置的空心板梁及横向连接空心板梁的铰缝混凝土，空心板梁上方由下至上依次为混凝土铺装层、桥面防水层和沥青铺装层。空心板梁的顶壁与混凝土铺装层之间存在脱空缝隙，空心板梁的侧壁与铰缝混凝土之间存在界面缝隙。铰缝混凝土内沿桥长方向钻设有多个孔道，孔道下端埋入用于向孔道内注胶的注胶针头，所述注胶针头通过封缝砂浆固定在铰缝底部。本发明还公开了一种空心板梁铰缝渗水修补方法。本发明在桥底施工，施工更方便；另外，本发明既能修补脱空缝隙和界面缝隙，又能同时修补铰缝混凝土中的细小缝隙，从而提高桥梁整体的防水性能。
