Technical Field
[0001] The utility model belongs to the technical field of mine equipment and relates to a mine drilling plugging grouting device. Background Art
[0002] Mine drilling grouting is a common geological engineering technology used to repair cracks, holes or leaks in underground structures to prevent water or other fluids from leaking into underground projects or mines. This technology is commonly used in mining, tunnel engineering, subway construction and underground pipelines.
[0003] When cracks exist in the side wall structure of a mine, the treatment procedure is to first drill a hole, then insert a catheter, and inject grout into the well wall until the grouting pressure reaches a specified value and then stops grouting. However, it often happens that after the grouting is completed, slurry still overflows from the borehole, affecting the plugging effect. Utility Model Content
[0004] The utility model aims to provide a mine drilling plugging grouting device to solve the problems existing in the prior art.

[0015] The utility model is described in detail below with reference to the accompanying drawings:
[0016] like Figure 1 As shown, a mine drilling plugging grouting device comprises a mine side wall 1, a borehole 2 is arranged on the mine side wall 1, and the borehole 2 is an existing conventional structure. When it is necessary to plug the crack, a borehole 2 is drilled at the corresponding position of the mine side wall 1, and grouting is injected into the crack through the borehole 2 to achieve plugging of the crack. When grouting plugging, a grouting pipe can be placed in the borehole 2 for grouting. A casing 3 is arranged in the borehole 2, and the casing 3 can be made of a steel pipe. The casing 3 and the borehole 2 are in an interference fit, and the casing 3 is fixed at the outer end of the borehole 2. When grouting, the grouting pipe can be passed through the casing 3 and then placed in the borehole 2. The diameter of the casing 3 is adapted to the diameter of the grouting pipe. After the grouting pipe passes through the casing 3, the casing 3 and the grouting pipe are in a clearance fit, so that the grouting pipe can move in the casing 3. An end plate 4 with a circular structure is fixed to the outer end of the casing 3, and the end plate 4 can be welded to the casing 3. The end plate 4 and the casing 3 They are arranged perpendicular to each other, and the end plate 4 is fixed to the mine side wall 1. The casing 3 can be fixed to the outer end of the drill hole 2 through the end plate 4. A plurality of fixing holes 5 are provided on the end plate 4 along the circumference of the end plate 7. Rivets 6 are provided in the fixing holes 5. The rivets 6 can be nailed into the mine side wall 1 to fix the end plate 7 on the mine side wall 1. The end plate 4 is provided with a through hole 7 coaxially arranged with the casing 3, and the grouting pipe can pass through the through hole 7. A slurry retaining plate 8 is detachably installed at the through hole 7. The slurry retaining plate 8 is used to block the through hole 7 after grouting is completed to prevent mortar from flowing out of the through hole 7. A plurality of mounting holes 9 are provided at the edge of the slurry retaining plate 8 along the circumference of the slurry retaining plate 8. A plurality of mounting screw holes 10 corresponding to the mounting holes 9 are provided on the end plate 4. Mounting screws 11 are provided in the mounting screw holes 10, and the mounting screws 11 pass through the mounting holes 9. When grouting is completed, the grouting pipe can be pulled out, and then the slurry retaining plate 8 is installed at the through hole 7.
[0017] The usage of the utility model is as follows:
[0018] When grouting and repairing the cracks, first place the casing 3 into the borehole 2, then insert the rivet 6 into the fixing hole 5 on the end plate 4 and then nail it into the mine side wall 1 to fix the end plate 4. Then the grouting pipe for grouting can be inserted into the through hole 7 of the end plate 4 and the casing 3 into the borehole 2, and then grouting can be started. During grouting, the grouting pipe is slowly moved outward. After the grouting is completed, the grouting pipe can be pulled out from the through hole 7 and the casing 3. After the grouting is completed, the slurry retaining plate 8 is installed at the through hole 7. Just pass the mounting screw 11 through the mounting hole 9 and install it in the mounting screw hole 10. The slurry retaining plate 8 can effectively prevent the mortar from flowing out of the borehole 2 after the grouting is completed.
