Water-rich sandy gravel stratum foundation pit grouting machine capable of controlling slurry seepage pressure and closed water stopping method
The invention relates to the technical field of foundation pit grouting machines, in particular to a water-rich sandy gravel stratum foundation pit grouting machine capable of controlling the slurry seepage pressure and a closed water stopping method. An auxiliary rack arranged on a grouting machine body can retract and release a guide pipe, and the grouting pressure can be adjusted and switched through an impact driving mechanism and a propelling mechanism; and the grouting pressure of the grouting machine is adjusted, the seepage pressure of the slurry in the water-rich sandy gravel stratum is guaranteed, and a hollow grouting area is avoided.
本发明涉及基坑注浆机技术领域，具体涉及一种可控料浆渗透压力的富水砂卵石地层基坑注浆机及封闭止水方法，注浆机主体上设置的辅助机架能够对导向管进行收放，并通过冲击驱动机构和推进机构能够对注浆压力进行调节切换，对注浆机的注浆压力进行调节，保证料浆在富水砂卵石地层中的渗透压力，避免出现灌浆镂空区域。
