Concrete crack repairing method
The invention discloses a concrete crack repairing method. The concrete crack repairing method comprises the following steps of cleaning a crack: detecting the depth and width of the crack by using equipment, then cleaning the ground near the crack, and when an opening in the top of the crack is smaller than 5mm, digging a groove with the width of 0.5-1cm along the crack, cleaning the inner wall of the crack by using a high-pressure water gun and a high-pressure air gun; preparing slurry: mixing and preparing a filling material according to a proportion, wherein the filling material is prepared from 50 to 55 parts of cement, 25 to 28 parts of fly ash, 10 to 12 parts of quartz sand, 2 to 5 parts of epoxy resin glue, 1 to 1.2 parts of redispersible latex powder, 0.5 to 1.5 parts of a water reducing agent and 0.2 to 0.6 part of a retarder; cement, fly ash, silica fume, epoxy resin glue, redispersible latex powder, the water reducing agent, the retarder and the like are used for preparing a high-viscosity filling slurry, filling is performed in three times, vibration equipment and air pressure are used for enabling the filling slurry to fully fill each corner of the crack, and a cavity is prevented from being generated in the crack.
本发明公开了一种混凝土裂缝的修补方法，包括以下步骤：清理裂缝：使用设备检测裂缝的深度和宽度，然后清理裂缝附近的地面，当裂缝顶部的开口小于5毫米时，沿裂缝开凿出槽宽度为0.5cm‑1cm的凹槽，然后使用高压水枪和高压气枪清理裂缝的内壁；配置浆液：按照比例混合配置填充料，填充料由水泥50份‑55份、粉煤灰25份‑28份，石英砂10份‑12份、环氧树脂胶2份‑5份、可再分散乳胶粉1份‑1.2份、减水剂0.5份‑1.5份、缓凝剂0.2份‑0.6份组成；利用水泥、粉煤灰，硅灰、环氧树脂胶、可再分散乳胶粉、减水剂和缓凝剂等配置成拥有强粘性的填充浆液，分成三次填充，并利用振动设备和空气压力让填充浆液充分填充裂缝的每一个角落，避免裂缝的内部产生空腔。
