Concrete bridge longitudinal crack glue pouring repairing method
The invention discloses a concrete bridge longitudinal crack glue pouring repairing method which comprises the following steps: drilling holes, drilling inclined holes in the two ends of a crack, drilling short straight holes in the outer ends of the inclined holes along the inclined direction of the end part of the crack, drilling a plurality of roulette holes along the crack at intervals, and treating the surface of the crack, a triangular groove with the depth being 1-4 mm and the opening angle being 100-120 degrees is ground in the outer surface of the crack through a grinding machine, the portions, 40-50 mm away from the two sides of the crack, of the concrete outer wall are ground and cleaned, and all protrusions are removed. The triangular groove is ground in the outer surface of the crack through the grinding machine, and then part of the strong concrete glue can enter the triangular groove when the crack is blocked, so that the permeability and bonding strength of the strong concrete glue and the crack are improved, the sealing effect on the crack is improved, and the actual effect of later-period glue pouring is further improved; and the gap filling strength after glue pouring is enhanced.
本发明公开了一种混凝土桥梁纵向裂缝灌胶修补方法，包括以下步骤：钻孔，在裂缝的两端钻出斜孔，且斜孔的倾斜方向沿着裂缝端部的倾斜方向设置，并在斜孔的外端钻出短直孔，再沿着裂缝间隔钻出多个骑缝孔，裂缝外表处理，在裂缝的外表通过打磨机打磨出深度在1‑4mm，张开角度为100°‑120°的三角槽，并对裂缝两侧40‑50mm的混凝土外壁进行打磨、清理，清除所有凸起。本发明通过在裂缝的外表通过打磨机打磨出三角槽，进而可以在对裂缝封堵时，使一部分强砼胶进入三角槽中，从而提高强砼胶与裂缝的渗入度和粘合强度，提高对裂缝的密封效果，从而进一步的提高了后期灌胶的实际效果，增强灌胶后对缝隙的填补强度。
