Grouting method for deep covering layer
The invention discloses a covering layer grouting method, which adopts tamping type grouting, controls the slurry diffusion range through quantitative grouting and intermittent grouting from bottom to top, realizes repeated splitting through different grouting pressures and slurry conversion, and realizes repeated splitting by controlling the grouting pressure conditions and different slurry conversion based on the control of the injection rate and the injection amount. A deep covering layer stratum is subjected to splitting, permeation and compaction repeated grouting along different paths for multiple times, and the grouting problems that the deep covering layer is prone to grout runout, treatment is uneven, and the effect is difficult to guarantee are effectively solved.
本发明公开了一种覆盖层灌浆方法，采用填压式灌注、自下而上、通过定量灌注和间歇灌注控制浆液扩散范围、通过不同灌浆压力和浆液变换实现重复劈裂的灌浆方法，基于注入率和注入量控制，利用控制灌浆压力条件和不同的浆液变换，对深厚覆盖层地层多次沿不同路径劈裂渗透挤密重复灌注，有效解决深厚覆盖层易跑浆、处理不均匀、效果难保证等灌浆难题。
