High-pressure jet grouting and stirring composite foundation reinforcing device
The invention discloses a high-pressure jet grouting and stirring composite foundation reinforcing device, and belongs to the technical field of engineering foundation reinforcing. The high-pressure jet grouting and stirring composite foundation reinforcing device is characterized in that a drill rod is provided with a hollow cavity, and a drill bit is arranged at the bottom end of the drill rod; the multiple stirring mechanisms are evenly arranged at intervals in the length direction of the drill rod and detachably connected with the drill rod. The grouting pipe, the high-pressure air pipe and the high-pressure water pipe are all located in the hollow cavity and are axially arranged in parallel, and the grouting pipe is connected with a high-pressure grout source; the high-pressure air pipe is connected with a high-pressure air source, the high-pressure water pipe is connected with a high-pressure water source, and the air nozzle, the first guniting port and the water nozzle are all arranged at the drill bit. A soil body is directly destroyed through the stirring mechanism arranged on the drill rod, in the spraying process, the drill rod rotates to drive the stirring blades to stir the soil body while lifting is conducted, slurry and the soil body are fully stirred and mixed, a columnar consolidation body with a certain diameter is formed in the soil, and therefore the foundation is reinforced.
本发明公开了一种高压旋喷搅拌复合地基加固装置，属于工程地基加固技术领域，其一种高压旋喷搅拌复合地基加固装置，包括：钻杆具有中空腔，钻杆的底端设置有钻头；多个搅拌机构沿钻杆的长度方向均匀间隔设置，多个搅拌机构与钻杆可拆卸连接；注浆管、高压气管与高压水管均位于中空腔内，注浆管、高压气管与高压水管三者轴向平行设置，注浆管连接高压浆源；高压气管连接高压气源，高压水管连接高压水源，喷气口、第一喷浆口与喷水口均设置于钻头处。本发明通过钻杆上设置的搅拌机构直接破坏土体，喷射过程中，钻杆边旋转带动搅拌叶片搅拌土体边提升使浆液与土体充分搅拌混合，在土中形成一定直径的柱状固结体，从而使地基达到加固效果。
