| 摘 要： | 三重管高压喷射注浆就是采用分别输送水、气和浆液3种工作介质的三重注浆管，使高压水、压缩空气冲击破坏土体，再让水泥浆液与土体搅拌混合，形成渗透系数为10^-7cm/s的固结体的岩土施工方法．它分为定喷和旋喷两种形式，适宜于地基加固和基础防渗．

| Abstract: | Three-dimensional high-pressure spray slip casting method is to use three slip-casting pipes transporting water, gas and cement paste respectively, let high-pressure water and compressed air strike and demolish soil, mix cement paste with the soil and form solid bodies with osmotic coefficient 10 ~ 7 cm/s. It includes two ways of fixed and rotary spray, and fits to reinforce groundwork and seepage control of foundations. |
