The bottom plug plate 1 is provided with a bottom plug plate grouting hole 3 and an exhaust through hole 4 connected to the slope grouting hole. The positioning ring 2 is locked on the bottom plug plate 1 by the locking adjustment component 6. The locking adjustment component 6 comprises a rotating shaft 61, an elliptical adjustment plate 62, a wave movable plate 63, a plug-in cone rod 64 and a compound The bottom plug plate 1 is rotatably connected to the rotating shaft 61, and an elliptical adjustment plate 62 matching the grouting hole 3 and the exhaust hole 4 of the bottom plug plate is provided on the rotating shaft 61. Wave movable plates 63, plug-in cone rods 64 and reset springs 65 are symmetrically arranged on both sides of the elliptical adjustment plate 62. The wave movable plate 63 matches the elliptical adjustment plate 62, one end of the plug-in cone rod 64 is fixed on the wave movable plate 63, and the other end of the plug-in cone rod 64 passes through the positioning ring 2 and is plugged into the inner wall of the slope grouting hole, and the reset spring 65 is arranged on the plug-in cone rod 64.

[0016] In this embodiment, refer to the attached Figure 1-6 The slope grouting stopping device is used to stop the grouting of the slope to prevent the grouting from flowing out and causing pollution and waste. It includes a bottom plug plate 1 inserted into the inside of the slope grouting hole. The upper surface of the bottom plug plate 1 is installed with a positioning ring 2 with the same outer diameter as the bottom plug plate 1. The bottom plug plate 1 and the positioning ring 2 are inserted to the position of the required slurry top surface height. Two bottom plug plate grouting holes 3 and exhaust holes 4 are symmetrical with the center of the bottom plug plate 1 as the symmetrical midpoint on any central axis passing through the center of the circle. Grouting is done into the slope grouting hole through the bottom plug plate grouting hole 3 connected to the external grouting pipe, and the air inside the slope grouting hole is discharged through the exhaust hole 4. A rotating hole 5 is opened in the center of the bottom plug plate 1, and a locking adjustment component 6 is rotatably installed on the rotating shaft 61. The locking adjustment component 6 can fix the position of the positioning ring 2 and the bottom plug plate 1 so that the top surface height of the grouting slurry is fixed. The positioning ring 2 is provided with two symmetrically arranged locking holes 7 , and a movable sleeve 8 is installed on the inner side of the locking holes 7 close to the positioning ring 2 .

[0017] The locking adjustment assembly 6 comprises a rotating shaft 61, an elliptical adjustment plate 62, a wave movable plate 63, a plug-in cone rod 64 and a reset spring 65. The rotating shaft 61 is rotatably mounted inside the rotating hole 5. The elliptical adjustment plate 62 is fixedly mounted on the rotating shaft 61. The elliptical adjustment plate 62 fits with the surface of the bottom plug plate 1. The elliptical adjustment plate 62 rotates on the surface of the bottom plug plate 1 through the rotating shaft 61. One side of the wave movable plate 63 is movably fitted with the elliptical adjustment plate 62, and the plug-in cone rod 64 is fixedly mounted on the other side. The plug-in cone rod 64 is movably plugged into the locking socket 7 and the movable A return spring 65 is installed inside the movable sleeve 8 and outside the plug-in cone rod 64 between the movable sleeve 8 and the wave movable plate 63. The return spring 65 always maintains an elastic force on the wave movable plate 63 toward the side of the elliptical adjustment plate 62. The different positions of the wave movable plate 63 are adjusted by fitting the different parts of the elliptical adjustment plate 62 with the wave movable plate 63, thereby driving the plug-in cone rod 64 to move inside the locking socket 7 and the movable sleeve 8, and to be plugged in with the side wall of the slope grouting hole, thereby fixing the position of the bottom plug plate 1 and the positioning ring 2.

[0018] An inner recess 631 is provided in the center of the wave movable plate 63, and the inner recess 631 has an arc-shaped depression on the side of the center of the positioning ring 2. An insert cone rod 64 is installed on the side of the inner recess 631 close to the movable sleeve 8, and a return spring 65 is installed on the outside of the insert cone rod 64 between the inner recess 631 and the movable sleeve 8. Two large-diameter fitting surfaces 621 and two small-diameter fitting surfaces 622 are provided on the elliptical adjustment plate 62. The small-diameter fitting surface 622 is movably fitted with the inner recess 631. When the small-diameter fitting surface 622 is fitted with the inner recess 631, the wave movable plate 63 can be pushed outward, thereby driving the insert cone rod 64 to extend to the outside of the positioning ring 2. At the same time, the inner recess 631 can limit the elliptical adjustment plate 62, and the elliptical adjustment plate 62 can be manually rotated.

[0019] The inner concave portion 631 has inner convex portions 632 integrally formed on both sides thereof, and the inner convex portions 632 are movably abutted against the large diameter fitting surface 621. When the elliptical adjustment plate 62 is rotated until the inner concave portion 631 is fitted with the large diameter fitting surface 621, the inserted cone rod 64 contracts toward the inside of the positioning ring 2, thereby unlocking the locking adjustment component 6 and the side wall of the grouting hole.

[0020] When the large diameter fitting surface 621 is in contact with the inner convex portion 632, the end of the plug-in cone rod 64 away from the inner concave portion 631 is inside the locking socket 7. At this time, the plug-in cone rod 64 is completely separated from the side wall of the grouting hole and returns to the inside of the locking socket 7, and the entire grouting device can be taken out of the grouting hole. When the small diameter fitting surface 622 is in contact with the inner concave portion 631, the end of the plug-in cone rod 64 away from the inner concave portion 631 extends to the outside of the positioning ring 2. At this time, the plug-in cone rod 64 is inserted into the side wall of the grouting hole, and the position of the grouting device can be locked.

[0021] The inside of the bottom plug plate grouting hole 3 and the exhaust hole 4 is provided with internal threads, and the internal spirals of the bottom plug plate grouting hole 3 and the exhaust hole 4 are spirally inserted with sealing plugs 9. The external threads of the sealing plugs 9 are spirally matched with the internal threads of the bottom plug plate grouting hole 3 and the exhaust hole 4, and are spirally inserted into the plug after the slope grouting is completed.

[0022] A rotating block 10 is fixedly mounted on the top of the rotating shaft 61 , and the rotating block 10 can facilitate the adjustment and rotation of the rotating shaft 61 and the elliptical adjustment block.

[0023] The present invention inserts the bottom plug plate 1 and the positioning ring 2 into the grouting hole, and then positions the bottom plug plate 1 and the positioning ring 2 through the locking and adjusting component 6. After positioning, grouting is injected through the bottom plug plate grouting hole 3. When slurry flows out of the exhaust through hole 4, the bottom plug plate grouting hole 3 and the exhaust through hole 4 can be blocked by the sealing plug 9. When disassembly is required, the sealing plug 9 is unscrewed, and the locking and adjusting component 6 is rotated to take out the bottom plug plate 1. The steps of installing and fixing the grouting hole and blocking the grouting hole of the grouting stop device are simple, and it is also convenient to disassemble and reuse after the grouting is completed.
