Karst landform hole collapse prevention hole pile perforating machine
The invention discloses a karst landform hole collapse prevention hole pile perforating machine which comprises drilling machine equipment, a supporting structure, an edge cutting assembly and a broken soil conveyor, the supporting structure is annular, and the diameter of a drill bit of the drilling machine equipment is 1/2-1/3 of the inner diameter of the supporting structure. According to the method, the diameter of the drill bit of the drilling machine equipment is 1/2-1/3 of the inner diameter of the supporting structure, the drilling machine equipment with the drill bit of the type can conduct drilling in the center of the supporting structure, the edge of a foundation pile hole is basically not affected by work of the drilling machine equipment, and therefore the influence on the edge of a foundation pit hole during drilling is avoided; and therefore, the collapse risk is reduced.
本发明公开了一种喀斯特地貌防塌孔孔桩打孔机，包括：钻机设备、支护结构、切边组件、碎土输送机，支护结构为环形，钻机设备的钻头的直径为支护结构的内径的1/2‑1/3。本发明，选择钻机设备的钻头的直径为支护结构的内径的1/2‑1/3，该种型号钻头的钻机设备能够在支护结构的中心处进行打孔，使基桩孔边缘处基本不会受到钻机设备工作的影响，从而避免了打孔时对基坑孔边缘造成影响，从而降低了塌陷的风险。
