The wall protection mud is usually a mixed slurry formed by adding water and stirring bentonite (or clay) and additives. In the process of mechanical pore-forming construction or underground excavation construction, the wall protection slurry is circularly conveyed, and the water pressure is controlled by utilizing the pressure difference between the wall protection slurry and underground water, so that the wall protection slurry can form a mud skin on the wall of the hole to reinforce the wall of the hole and prevent the wall of the hole from collapsing. In addition, the wall protection slurry with certain viscosity can also stabilize the water level in the hole. In addition, the wall mud also has the effect of cooling and lubricating the drill bit and carrying out rock debris.
