Description

Technical Field

[0001] The invention relates to the field of grouting construction, in particular to a blocking device for grouting an anchor hole. Background Art

[0002] Slope reinforcement refers to measures to improve the stability of open-pit mine slopes by setting up corner retaining walls at the bottom of the slope corners and anchor frame beams on the slope surface.

[0003] In order to improve the stability of the slope, anchor frame beam is a new type of slope reinforcement technology. It has an ideal effect on the reinforcement of high expansive soil slopes and weathered soil slopes and is widely used. Grouting work in the hole is required during construction, which is very important. However, the existing work efficiency is not ideal, and there are few hole sealing reinforcement structures. Generally, there are no measures at the anchor hole, and the grouting pipe is directly inserted for grouting. The grouting duration is until the cement slurry flows out of the hole, and then the grouting is stopped. This method can easily cause incomplete grouting at the anchor hole, insufficient grouting pressure, and cement slurry that does not generate strength and flows out of the anchor hole, resulting in poor quality of cement slurry pouring at the anchor hole, missing edges and corners, and incompleteness. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a blocking device for grouting an anchor hole, so as to solve the problems that the cement slurry pouring quality at the existing anchor hole is poor, and it is easy to be missing edges and corners and incomplete.

[0005] The technical solution to achieve the above-mentioned purpose is: a sealing device for grouting an anchor hole, comprising: a panel, which is arranged on the outside of the anchor hole; a first grouting hole, which is arranged on the panel and is used for a grouting pipe to extend into the anchor hole for grouting; a first circular hole, which is arranged on the panel and is adjacent to the first grouting hole, and the first circular hole is used for the main reinforcement of the anchor to pass through; a side ring plate, one end of which is connected to the inner plate surface of the panel, and the other end of the side ring plate is correspondingly inserted into the anchor hole and against the inner wall of the anchor hole.

[0006] In a blocking device for grouting an anchor hole of the present invention, the anchor hole is blocked by a panel and a connected side ring plate to prevent cement slurry from leaking due to gaps, thereby ensuring construction quality. The first grouting hole and the first circular hole opened on the panel can ensure the implementation of grouting, thereby improving work efficiency, reducing material waste and saving costs.

[0007] A further improvement of the blocking device for grouting an anchor hole of the present invention is that the end of the side ring plate inserted into the anchor hole is bent inwardly.

[0008] A further improvement of the blocking device for grouting an anchor hole of the present invention is that a second grouting hole is provided on the upper side of the side ring plate.

[0009] A further improvement of the blocking device for grouting an anchor hole of the present invention is that it also includes: a hole blocking plug, and the hole blocking plug is corresponding to blocking the second grouting hole.

[0010] A further improvement of the blocking device for grouting an anchor hole of the present invention is that a plurality of second circular holes are further provided on the panel, and the second circular holes are used for passing the steel strands.

[0011] A further improvement of the blocking device for grouting an anchor hole of the present invention is that the steel strand and the grouting pipe both extend from the end of the side ring plate and into the interior of the anchor hole.

[0012] A further improvement of the blocking device for grouting an anchor hole of the present invention is that a plurality of the second circular holes are arranged at intervals around the panel.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 A front view of the occluding device of the present invention is shown, Figure 2 The schematic diagram of the structure of the plugging device for grouting the anchor hole of the present invention is shown. Figure 3 Another structural schematic diagram of a plugging device for anchor hole grouting of the present invention is shown. The present invention provides a plugging device for anchor hole grouting, comprising: a panel 10, which is arranged outside the anchor hole 21.

[0022] The diameter of the panel 10 is set to be larger than the diameter of the anchor hole 21 . The panel 10 can be round or square. There is no specific limitation on the shape of the panel 10 .

[0023] In this embodiment, after the drilling machine drills the anchor hole 20 on the slope, an anchor hole 21 is formed on the slope surface.

[0024] The first grouting hole 11 is provided on the panel 10 and is used for the grouting pipe 30 to extend into the anchor hole 21 for grouting.

[0025] Among them, the first grouting hole 11 is set through the panel 10, and the grouting pipe 30 can transport and inject the special grouting material into the anchor hole 20 to complete the casting requirements.

[0026] The first circular hole 12 is disposed on the panel 10 and is adjacent to the first grouting hole 11 . The first circular hole 12 is used for the main anchor bar 31 to pass through.

[0027] The first circular hole 12 and the first grouting hole 11 are symmetrically arranged on the panel 10 with the center point as the symmetrical point.

[0028] In this embodiment, the first circular hole 12 and the first grouting hole 11 are symmetrically arranged up and down, and the first circular hole 12 is arranged above the first grouting hole 11. In other embodiments, the first circular hole 12 and the first grouting hole 11 can be symmetrically arranged left and right, and no specific limitation is made here.

[0029] The side ring plate 13 has one end connected to the inner plate surface of the panel 10 , and the other end of the side ring plate 13 is correspondingly inserted into the anchor hole 21 and abuts against the inner wall of the anchor hole 21 .

[0030] A groove-shaped space is formed between the side ring plate 13 and the panel. During construction, the side ring plate 13 is pressed tightly into the anchor hole 21. When the outer wall of the side ring plate 13 fits with the inner wall of the anchor hole 21, a sealing effect can be achieved.
