[0018] The following is combined with Figure 1-3 , further illustrating a specific implementation of a precise directional grouting device of the present invention. A precise directional grouting device of the present invention is not limited to the description of the following embodiments.

[0019] Embodiment 1:

[0020] This embodiment provides a specific structure of a precise directional grouting device, such as Figure 1-3 As shown, it includes a grouting machine 1 and a grouting head 2, the grouting machine 1 and the grouting head 2 are connected by a pipeline, the grouting head 2 adopts a hollow structure, including an inner cavity 3, a chute 4 is opened at the bottom end of the outer wall of the grouting head 2, a grouting conduit 5 is arranged in the chute 4, and the grouting conduit 5 is rotatably connected to the side wall of the chute 4 through a torsion shaft;

[0021] A guide plate 6 is provided in the inner cavity 3, a spring 7 is provided below the guide plate 6, a plurality of limit blocks 8 are provided on the inner side of the bottom wall of the inner cavity 3, the inner cavity 3 is connected with the slide groove 4 through a through hole, and a connecting piece 9 is provided between the torque shaft and the guide plate 6 for controlling the rotation of the torque shaft.

[0022] A plurality of exhaust holes 10 are provided on the bottom wall of the inner cavity 3 .

[0023] The guide plate 6 is slidably connected to the inner wall of the inner cavity 3 .

[0024] The rotating end of the grouting conduit 5 adopts a circular structure, and the torsion spring is arranged at the center of the rotating end of the grouting conduit 5 .

[0025] The through hole adopts a cylindrical structure, and the center of the rotating end of the grouting conduit 5 is on the central axis of the through hole.

[0026] Working principle: Figure 1-3 As shown, first, the grouting machine 1 is connected to the grouting head 2 through a pipeline, the grouting head 2 is placed at the pre-grouting position, the grouting machine 1 is started, the slurry enters the inner cavity 3 through the pipeline, the guide plate 6 slides down in the inner cavity 3 due to the grouting pressure, and the guide plate 6 drives the grouting conduit 5 to rotate through the connecting piece 9;

[0027] The rotating end of the grouting conduit 5 adopts a circular structure, and the rotating end is sealed and connected to the side wall of the through hole. A through channel is opened on the grouting conduit 5. As the grouting conduit 5 rotates, the channel opening of the rotating end is connected to the through hole, and the slurry is injected to the surroundings through the grouting conduit 5. The limit block 8 can control the displacement length of the guide plate 6 to control the grouting conduit 5. When the grouting is stopped, the spring 7 under the guide plate 6 resets it, and the torsion shaft drives the grouting conduit 5 to reset, and the grouting process is completed.

[0028] By increasing the grouting pressure and grouting effect through the grouting conduit 5, the pre-treated area can be accurately reached for grouting, avoiding the difficulty of the grouting head 2 in drilling and preventing the grouting head 2 from being stuck due to the instability of the surrounding soil during the grouting process.
