Foundation pit water gushing port plugging method based on double-liquid grouting method under complex stratum conditions
The invention discloses a foundation pit water gushing port plugging method based on a double-liquid grouting method under complex stratum conditions, and relates to the field of engineering construction. The preparation method comprises the following steps: respectively injecting cement paste and a sodium silicate aqueous solution into a mixer according to a second preset proportion for mixing toform mixed paste; injecting the mixed slurry into the grouting hole within a preset grouting pressure range; obtaining the grouting time and the grouting pressure of the mixed slurry; judging whetherthe grouting time required for the grouting pressure to reach the preset pressure is less than the preset time or not; in the state that the grouting time is shorter than the preset grouting time, adjusting the ratio of the cement paste to the sodium silicate aqueous solution to be larger than a second preset ratio; judging whether the grouting pressure is smaller than the preset pressure when the grouting time reaches the preset time or not; and in the state that the grouting pressure is smaller than the preset pressure, adjusting the proportion of the cement paste to the sodium silicate aqueous solution to be smaller than the second preset proportion.
本申请公开了一种复杂地层条件下基于双液注浆法的基坑涌水封堵方法，涉及工程施工领域。包括如下步骤：将水泥浆和硅酸钠水溶液按照第二预设比例分别注入至混合器中进行混合，形成混合浆；将混合浆在预设注浆压力范围内注入至注浆孔内；获取混合浆的注浆时间和注浆压力；判断注浆压力达到预设压力所需要的注浆时间是否小于预设时间；在注浆时间小于预设注浆时间的状态下，调节水泥浆和硅酸钠水溶液的比例，使水泥浆和硅酸钠水溶液的比例大于第二预设比例；判断注浆时间达到预设时间注浆压力的大小是否小于预设压力；在注浆压力小于预设压力的状态下，调节水泥浆和硅酸钠水溶液的比例，使水泥浆和硅酸钠水溶液的比例小于第二预设比例。
