Multi-pipe multi-fluid high-pressure jet grouting device for collapsible loess reinforcement
The invention provides a multi-pipe multi-fluid high-pressure jet grouting device for collapsible loess reinforcement, and belongs to the technical field of collapsible loess reinforcement, the multi-pipe multi-fluid high-pressure jet grouting device comprises a drill bit, a first jet grouting assembly, a second jet grouting assembly and a third jet grouting assembly are arranged in the drill bit, the first jet grouting assembly comprises a first pipeline, and a first annular pipe is arranged at the lower end of the first pipeline; a first conveying opening is formed in the outer side wall of the first annular pipe; according to the loess stirring device, high-pressure gas, a salt solution and an alkali solution can be sprayed out while stirring is carried out, so that after the high-pressure gas, the salt solution and the alkali solution are added into loess, the stirring efficiency is further improved, the loess is stirred more uniformly, and the loess stirring efficiency is improved. And compared with a traditional mode that only one solution can be added, after the salt solution and the alkali solution are added at the same time, the reinforcing effect of the collapsible loess can be improved, and therefore the overall stability of the foundation is improved.
本发明提供了一种用于湿陷性黄土加固的多管多流体高压旋喷装置，属于湿陷性黄土加固技术领域，包括钻头，钻头内设有第一旋喷组件、第二旋喷组件与第三旋喷组件，第一旋喷组件包括第一管道，第一管道下端有第一环形管，第一环形管外侧壁开设有第一输送口；还包括第一轨槽，钻头位于第一轨槽处圆周开设有若干第一喷孔，本发明在进行搅拌的同时，可以喷出高压气体、盐溶液与碱溶液，使得黄土在加入了高压气体、盐溶液与碱溶液后，进一步提高搅拌效率，使黄土搅拌地更加均匀，并且比传统只能加单一一种溶液的方式，同时加入盐溶液与碱溶液后，还可以提高湿陷性黄土的加固效果，以此提高地基整体的稳定性。
