Triple-pipe double-high-pressure jet grouting reinforcement construction method and high-pressure jet grouting equipment
The invention relates to a triple-pipe double-high-pressure jet grouting reinforcement construction method, which belongs to the technical field of high-pressure jet grouting piles, and comprises the following steps: S1, performing primary cutting and drilling, namely performing soil cutting on a hole wall while drilling; s2, secondary cutting and hole filling are conducted, and soil cutting is conducted on the hole wall again while material filling is conducted on the hole; s3, grouting and stirring the slurry in the hole, and compacting and stirring the slurry in the hole at the same time; and S4, orifice slurry supplementing. The construction method has the effect that when a complex soft soil foundation is treated, a sludge solidification pile body with larger width and depth can be constructed.
本申请涉及一种三重管双高压旋喷注浆加固施工方法，属于高压旋喷桩技术领域，其包括以下步骤：S1、一次切削钻孔，在进行钻孔的同时对孔壁进行土壤切削；S2、二次切削灌孔，在对孔进行灌料的同时对孔壁再次进行土壤切削；S3、孔内浆料压浆搅拌，对孔内的浆料同时进行压实和搅拌；S4、孔口补浆。本申请具有实现在处理复杂软土地基时，能够施工宽度和深度更大的淤泥固化桩体的效果。
