Basement floor plate crack reinforcing and repairing construction method
The invention discloses a basement floor crack reinforcing and repairing construction method. It is characterized in that a pressure relief hole is formed in a crack water seepage area of a floor to guide water, the pressure of underground water on the floor is reduced, then grouting liquid is injected in a high-pressure grouting manner to repair, seal and fill the floor, and the cement grouting liquid has good permeability to concrete and good bonding effect so that cracks can be effectively sealed, the adding proportion of water glass is controlled in the grouting process, the slurry hardening time is shortened, the cohesiveness and hardness of the grouting liquid is improved after the grouting, the problem that most of the grouting liquid is washed away after the grouting due to too much underground flowing water, and reinforcing and strengthening treatment is conducted on the area after the grouting, and the purposes of repairing the cracks and reinforcing the floor are achieved.
本发明公开了一种地下室底板冲裂加固修复施工方法，在底板开裂渗水区域安装泄压孔引水，减少地下水对于底板的压力，再通过高压注浆的方式注入浆液修复及封填充底板，因水泥浆液对混凝土具有良好的渗透性，其粘结效果好，能有效地密封裂缝，注浆过程中控制水玻璃加入的比例，缩短浆液硬化时间，提高注浆液在注浆后的粘结性及硬度，能有效避免因地下流动水过大而导致注浆后浆液被大部分冲走的问题，完成注浆后再对该区域进行加固补强处理，达到修复裂缝加固底板的目的。
