Full-casing large-diameter perturbation high-pressure jet grouting method
The invention discloses a full-casing large-diameter micro-disturbance high-pressure jet grouting method, which relates to the technical field, and comprises the following steps of: 1, putting a pile machine in place, 2, rotating and sinking a casing to downwards jet water and gas, and 3, rotating and lifting the casing to laterally jet cement paste and gas. Peripheral soil disturbance is small, the pile forming diameter is large, perpendicularity is easy to control, and the utilization rate of consolidation materials is high.
本发明公开了一种全套管大直径微扰动高压喷射注浆方法，涉及技术领域，包括步骤一：桩机就位，步骤二：套管旋转下沉向下喷射水、气，步骤三：套管旋转提升侧向喷射水泥浆、气。本发明周边土体扰动小，成桩直径大，垂直度易于控制，固结材料利用率高。
