Soft foundation compacting and drainage reinforcing method combining high-pressure sand blasting pile and heaped loading
The invention discloses a high-pressure sand blasting pile combined loading soft foundation compaction and drainage reinforcement method which comprises the following steps: step 1, firstly, leveling a site, then, carrying out soft foundation exploration, ascertaining a geologic structure in a soft soil foundation to be treated, and then, paving a lower drainage cushion layer; step 2, measuring a discharge point, and placing a pile forming system in place; thirdly, a pile forming system is used, a hole is drilled in the pile forming point position, then high-pressure rotary jet grouting pile forming construction is conducted, and a high-pressure sand jet pile is constructed; 4, paving a drainage cushion layer on the upper layer, and arranging a water filter pipe in the drainage cushion layer; 5, geotextile is laid on the drainage cushion layer, and a water filter pipe in the drainage cushion layer is led out and connected with a drainage system; and sixthly, stacking and loading materials on the geotechnical cloth step by step, and carrying out stacking and pre-pressing drainage on the soft soil foundation.
本发明公开了一种高压喷射砂桩联合堆载的软基密实、排水加固方法，包括以下步骤：步骤一，首先场地整平，之后进行软基勘探，探明待处理的软土地基中的地质结构，然后摊铺下层的排水垫层；步骤二，测量放点，并就位成桩系统；步骤三，使用成桩系统，先在成桩点位钻孔，之后进行高压旋喷成桩施工，构建高压喷射砂桩；步骤四，摊铺上层的排水垫层，排水垫层内布设滤水管；步骤五，排水垫层上铺设土工布，将排水垫层内的滤水管引出，与排水系统相连接；步骤六，土工布上逐级堆载堆载料，对软土地基进行堆载预压排水。
