Grouting construction process for optimizing bridge crack repairing effect
The invention discloses a grouting construction technology for optimizing the bridge crack repairing effect. The grouting construction technology comprises the following steps that S1, bridge cracks are investigated and analyzed; s2, holes are drilled in a plum blossom shape in a staggered mode along the two sides of the crack, and the drilling depth and the drilling interval are optimized according to the steel bar burial depth and the corresponding durability index; s3, pollutants attached in concrete cracks are dissolved through a special crack cleaning agent, and water is pressed to wash the pollutants; s4, carrying out first porous parallel grouting by using a water-foamed grouting material, and discharging water in the crack to form a cavity structure tightly connected with the concrete; s5, secondary multi-hole parallel grouting is conducted, an inner cavity of the cavity structure formed after primary grouting is filled with the grouting material, and a dense repairing structure is formed; and S6, plugging the hole, and polishing to be smooth. Through process optimization, it is ensured that the structure of the grouting material in the crack is a uniform and dense structure, and effective protection is formed on steel bars in the structure, so that the durability of the structure after repair is improved.
本发明公开了一种优化桥梁裂缝修补效果的灌浆施工工艺，包括以下步骤：S1、桥梁裂缝调查分析；S2、沿裂缝两侧呈梅花状交错钻孔，并根据钢筋埋深和相应的耐久性指标来优化钻孔深度和钻孔间距；S3、使用专用清缝剂溶解混凝土裂缝内附着的污染物，并压水冲洗污染物；S4、使用遇水发泡灌浆料进行第一次多孔并灌，将裂缝内部水排出，形成与混凝土紧密连接的空腔结构；S5、第二次多孔并灌，将灌浆料填充满第一次灌浆后形成的空腔结构的内部空腔，形成密实修复结构；S6、封堵孔洞、打磨平整。本发明通过工艺优化，保证灌浆料在裂缝内的结构为均匀密实结构，以及对结构内部钢筋形成有效保护，从而提高了结构修复后的耐久性能。
