Stone micro-pressure grouting concrete structure reinforcing method
The invention discloses a pebble micro-pressure grout-filled concrete structure reinforcing method, which belongs to the field of buildings and comprises the following steps of: 1, chiseling away incompact concrete, cleaning a section, and trimming reinforcing steel bars; 2, binding iron gauze cloth, filling coarse aggregate pebbles, and uniformly distributing the coarse aggregate pebbles, the putting amount of the coarse aggregate pebbles being about 50-60% of the volume of the cavity; thirdly, the reinforcing formwork is blocked, and a slurry inlet and a material supplementing hopper are reserved; fourthly, a grouting material mixture is mixed, slurry is slowly injected from a slurry inlet through a grouting machine till the cavity space is filled with the slurry, and the supplementing hopper is filled with the slurry; fifthly, the grouting pipe is removed, and a grout inlet is blocked; and sixthly, 24 hours later, after the grouting material is solidified, the material supplementing hopper is removed, and mold removal and maintenance are conducted. According to the invention, local materials are easy to obtain, the strength is high, the crack resistance is strong, the quality is guaranteed, the acceptance is simple and convenient, and the application range is wide.
本发明公开了一种石子微压充浆混凝土结构加固方法，属于建筑领域，包括以下步骤：第一步：凿除不密实混凝土，清洗干净断面，并修整钢筋；第二步：绑扎铁丝网布，填塞粗骨料石子，并使其均匀分部，粗骨料石子投放量约占空洞体积的50％‑60％；第三步：封堵加固模板，留置进浆口与补料斗；第四步：拌制灌浆料拌合物，用注浆机从进浆口缓慢注入浆料，直至浆料充满空洞空间，并充满补料斗；第五步：撤下注浆管，封堵进浆口；第六步：24小时后，待灌浆料凝固后，撤下补料斗，拆模养护。本发明实现材料易于就地取材，同时强度高、抗裂性强、质量有保证、验收简便且适用范围广。
