  • Patent number: 11773683
    Abstract: A segmented grouting method for ramp drivage in an aquifer is provided. Concerning grouting reinforcement for a ramp in an aquifer, a grouting process is divided into four stages according to a pressure change, that is, micro-pressure filling, low-pressure diffusion, medium-pressure reinforcement, and high-pressure fracturing. In the micro-pressure filling, an initial pressure of a grouting orifice is 0, and a low-concentration single-component grout is used to fill an original fissure of the aquifer. In the low-pressure diffusion, a low-concentration bicomponent grout is used for grouting, the original fissure is expanded, and a grouting radius is increased. In the medium-pressure reinforcement, a high-concentration bicomponent grout is used for grouting, thereby reinforcing the aquifer. In the high-pressure fracturing, a high-concentration bicomponent grout is used to reinforce a new fractured fissure of the orifice caused by a high pressure and the original fissure, thereby forming a confining bed.
