Karst stratum stabilization structure
The invention provides a karst stratum stabilization structure used for constructing a punch filling pile. The punch filling pile penetrates through at least one cave in a karst stratum from top to bottom; a hole-wall treatment structure comprises a casing, a pile hole of the punch filling pile, a hole-wall crack water neutralization layer of the pile hole and a mud protection layer, wherein the casing is embedded into the karst stratum at a pile position of the constructed punch filling pile before the punch construction of a top plate of the cave for a certain depth and is far away from the surface of the karst stratum for a certain height; the pile hole is concentric to the casing, and the diameter of the pile hole is smaller than that of the casing; the mud protection layer punctures a cave wall and a pile hole wall behind the top plate of the cave and is sealed, tight and waterproof. Due to the fact that a karst area is treated by using flagstones, clay, straws, cement and the like, the engineering progress is rapid, the engineering quality is reliable, the construction is safe, general resources can be better utilized, and a great number of concrete materials are saved.
