Embodiment 1
[0011] A settlement reinforcement jacking and leveling method suitable for independent pile foundations of industrial plants, such as figure 1 As shown in the figure, the weak soil layer around the pile is first reinforced by compaction and grouting. The reinforcement depth is from shallow to deep, and the layers are downward. The grouting pressure is from small to large. The length of each grouting section is 0.5-1.0m. After the first grouting section, continue drilling for 0.5-1.0m, carry out the grouting of the second grouting section, and go down section by section until the compaction grouting is completed. The scheme can avoid secondary settlement caused by the weakening of the soil layer when the soil layer encounters water during the drilling process. The compaction and grouting reinforcement of the soft soil layer around the pile can improve the compactness and friction coefficient of the soft soil layer around the pile. The layer is reinforced, and a concave-shaped ...
