[0031] In this embodiment, the outer wall of the cement pipe 4 is rotatably installed with a sub drill bit 3 at the left side, which is located at the bottom of the ground level and is sleeved with the main drill rod 2 at the center of the circle.
[0032] It should be noted that the sub drill bit 3 as a component directly acting on the stratum, its rotatable installation design makes the drill bit more flexible to cope with different hardness and geological conditions of the stratum, and the sleeved connection with the main drill rod 2 ensures the continuity and stability of power transmission, thereby enhancing the efficiency and depth of drilling.
