[0002] Grouting anchor construction is a common foundation reinforcement technology, which is widely used in the field of geotechnical engineering, especially in slope management, tunnel support, underground space development and other projects. During the tunnel construction process, cracks often appear between the rock blocks of the tunnel wall. In order to prevent tunnel collapse, it is necessary to anchor the rock cracks. During the specific construction, first use an electric drill to drill an anchor hole in the rock crack, and then insert the grouting anchor into the bottom of the anchor hole. By grouting the anchor hole, the slurry is filled in the rock cracks and the anchor hole. After the slurry solidifies, the tunnel rock wall can be reinforced.

[0048] During use: the travel motor 8 controls the base 16 to move to the anchoring construction area in the tunnel. When drilling, it is first necessary to fix the position of the base 16, insert the end of the drill bit into the positioning hole of the three-jaw hydraulic chuck 1, and then fix the drill bit through the three-jaw hydraulic chuck 1.

[0049] The drill bit is flipped to a certain angle through the large torque output mechanism 6 so that the drill bit can face downward, and the drilling motor 3 is started. The drilling motor 3 drives the drill bit to rotate, and the hydraulic telescopic rod 29 contracts and presses down the drill bit, so that the drill bit can drill a positioning hole on the ground.

The hydraulic telescopic rod 1 5 is extended to press the drill bit down, and the synchronous drilling motor 3 drives the drill bit to rotate, thereby performing the anchor hole drilling operation.

[0051] After the drilling of the anchor hole is completed, the drill bit is retracted and removed, and then the grouting anchor rod is inserted into the inner sleeve 26 through the three-jaw hydraulic chuck 1, and the grouting port at the end of the anchor rod is connected with the grouting connector 24, and the external grouting pipe is plugged into the grouting connector 24, and the outer side of the anchor rod is clamped by the three-jaw hydraulic chuck 1, and the anchor rod is inserted into the anchor hole just drilled by controlling the hydraulic telescopic rod 29, the hydraulic telescopic rod 6 20 and the hydraulic telescopic rod 1 5. When the grouting plug on the outer side of the anchor rod is pressed tightly against the anchor hole mouth, the grouting machine is started, and the high-pressure slurry enters the grouting anchor rod through the grouting connector 24, and finally flows out through the grouting anchor rod and fills the gap between the anchor hole and the rock wall, thereby realizing rapid anchoring of the rock wall.

[0052] It is worth noting that the input ends of the punching motor 3, the hydraulic pump, the travel motor 8, the reduction motor 12 and the torque motor 36 are all electrically connected to the output end of the external power supply through an external control switch.
