[0004] Although the above patent uses a filter plate to filter large impurities in the slurry to prevent the slurry outlet pipe from being blocked, in order to deal with the impurities on the filter plate, it is necessary to rotate the pipe cover to remove the filter plate. When the filter plate is slightly blocked, it is also necessary to rotate the pipe cover to deal with the filter plate, which undoubtedly affects the grouting efficiency. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that the impurities on the filter plate need to be processed by rotating the pipe cover, which affects the grouting efficiency, and proposes a grouting pipe for water conservancy projects.

[0009] Preferably, the outer wall of the bidirectional screw is threadedly connected to two sliders, both of which are slidably connected to the slide rod, and the outer walls of the two sliders are fixedly installed with arc-shaped clamping plates, and the outer walls of the two arc-shaped clamping plates are fixedly installed with rubber pads.

[0010] Preferably, a second rotating plate is movably inserted into the top of the installation frame, and an output shaft of the second rotating plate passes through the top of the installation frame and is fixedly connected to one end of the outer wall of the bidirectional screw.

[0011] Preferably, a drill bit is fixedly mounted on the bottom end of the grouting pipe body, and a group of grouting holes are penetrated through the outer wall of the grouting pipe body.

[0012] Preferably, the sealing cover is threadedly connected to the grouting pipe body, and the two connecting plates are fixedly connected to the grouting pipe.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, a filter screen is arranged in the main body of the grouting pipe, and the filter screen can filter the slurry entering from the slurry inlet pipe to prevent some larger impurities from clogging the grouting holes. When there are some impurities that clog the surface of the filter screen, the first rotating plate can be rotated, and the first rotating plate drives the rotating rod to rotate, and the rotating rod drives the hard-bristle brush to rotate on the surface of the filter screen. When the hard-bristle brush rotates on the surface of the filter screen, some blocked impurities will be removed from the surface of the filter screen, thereby preventing the impurities from affecting the filtering effect of the filter screen. When there are many impurities on the surface of the filter screen and the hard-bristle brush cannot handle the impurities, the sealing cover can be rotated, and then the filter screen is taken out from the main body of the grouting pipe, so as to facilitate the treatment of impurities on the surface of the filter screen.

[0015] 2. In the utility model, when it is necessary to inject slurry, the slurry inlet pipe is connected with the external pipe, and then the slurry is injected into the slurry inlet pipe through the external pipe. However, when the slurry is injected, the slurry inlet pipe and the external pipe will vibrate to a certain extent. The vibration generated by the long-term injection of slurry may cause the connection between the slurry inlet pipe and the external pipe to loosen or even fall off. At this time, the second rotating plate can be rotated, and the second rotating plate drives the bidirectional screw to rotate. The bidirectional screw drives the two sliders to approach each other during the rotation process, and the two sliders drive the two arc-shaped clamping plates to approach each other until the two arc-shaped clamping plates clamp the connection between the slurry inlet pipe and the external pipe, thereby reducing the vibration generated at the connection between the slurry inlet pipe and the external pipe, improving the connection strength between the slurry inlet pipe and the external pipe, and reducing the probability of the connection between the slurry inlet pipe and the external pipe loosening or even falling off.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 6 As shown, the utility model provides a grouting pipe for a water conservancy project, comprising a grouting pipe body 1, the outer wall of the grouting pipe body 1 is fixedly connected with a grouting pipe 5, the outer wall of the grouting pipe 5 is provided with a clamping mechanism 7, the top outer wall of the grouting pipe body 1 is provided with an external thread 4, and the top of the grouting pipe body 1 is provided with a filtering mechanism 6;

[0026] The filtering mechanism 6 includes a sealing cover 601, the inner wall of which is provided with an internal thread 602, two connecting rods 603 are fixedly installed on the top of the inner wall of the sealing cover 601, and a filter screen plate 604 is fixedly installed on the bottom ends of the two connecting rods 603, a rotating rod 605 is movably inserted at the top of the sealing cover 601, the bottom end of the rotating rod 605 passes through the top of the sealing cover 601 and is rotatably connected to the filter screen plate 604, a bristle brush 607 is fixedly installed on the outer wall of the rotating rod 605, the bristle brush 607 is slidably connected to the filter screen plate 604, and a first rotating plate 606 is fixedly installed on the top of the rotating rod 605.

[0027] The effect achieved by the entire embodiment 1 is that the external thread 4 facilitates the fixed installation of the filtering mechanism 6 in the grouting pipe body 1, the slurry inlet pipe 5 can be connected to the external pipeline, and then the slurry is injected into the grouting pipe body 1, and the filter screen plate 604 can filter the incoming slurry to prevent some larger impurities from clogging the grouting holes 3. When there are some impurities that block the surface of the filter screen plate 604, the first rotating plate 606 can be rotated, and the first rotating plate 606 drives the rotating rod 605 to rotate, and the rotating rod 605 drives the bristle brush 607 to rotate on the surface of the filter screen plate 604. When the bristle brush 607 rotates on the surface of the filter screen plate 604, some blocked impurities will be removed from the surface of the filter screen plate 604, thereby preventing the impurities from affecting the filtering effect of the filter screen plate 604. When there are many impurities on the surface of the filter screen plate 604 and the bristle brush 607 cannot handle the impurities, the sealing cover 601 can be rotated, and then the filter screen plate 604 is taken out from the grouting pipe body 1, so as to facilitate the treatment of impurities on the surface of the filter screen plate 604.

[0028] Embodiment 2, as Figure 1-Figure 6As shown, the clamping mechanism 7 includes a mounting frame 701, a bidirectional screw 702 is rotatably mounted on the inner wall of the mounting frame 701, a slide bar 703 is fixedly mounted on the inner wall of the mounting frame 701, and two connecting plates 708 are fixedly mounted on the inner wall of the mounting frame 701. The outer wall of the bidirectional screw 702 is threadedly connected with two sliders 704, and the two sliders 704 are both slidably connected with the slide bar 703. The outer walls of the two sliders 704 are both fixedly mounted with arc clamps 705, and the outer walls of the two arc clamps 705 are both fixedly mounted with rubber pads 706. A second rotating plate 707 is movably inserted at the top of the mounting frame 701, and the output shaft of the second rotating plate 707 passes through the top of the mounting frame 701 and is fixedly connected to one end of the outer wall of the bidirectional screw 702. A drill bit 2 is fixedly mounted on the bottom end of the grouting pipe body 1, and a group of grouting holes 3 are opened through the outer wall of the grouting pipe body 1. The sealing cover 601 is threadedly connected to the grouting pipe body 1 , and the two connecting plates 708 are fixedly connected to the grouting pipe 5 .

[0029] The effect achieved by the entire embodiment 2 is that when it is necessary to clamp and fix the connection between the slurry inlet pipe 5 and the external pipe, the second rotating plate 707 is rotated, and the second rotating plate 707 drives the bidirectional screw 702 to rotate. The bidirectional screw 702 drives the two sliders 704 to approach each other during the rotation process, and the two sliders 704 drive the two arc-shaped clamping plates 705 to approach each other until the two arc-shaped clamping plates 705 clamp and fix the connection between the slurry inlet pipe 5 and the external pipe, thereby reducing the vibration generated at the connection between the slurry inlet pipe 5 and the external pipe, improving the connection strength between the slurry inlet pipe 5 and the external pipe, and reducing the probability of the connection between the slurry inlet pipe 5 and the external pipe becoming loose or even falling off. At the same time, the surface of the arc-shaped clamping plate 705 is provided with a rubber pad 706, which can increase the friction against the pipe, and the rubber pad 706 can also absorb some vibration generated at the connection.

[0030] Working principle: when it is necessary to inject slurry, the slurry inlet pipe 5 is connected with the external pipe, and then the slurry is injected into the slurry inlet pipe 5 through the external pipe. However, when the slurry is injected, the slurry inlet pipe 5 and the external pipe will vibrate to a certain extent. Long-term injection of slurry may cause the vibration to cause the connection between the slurry inlet pipe 5 and the external pipe to loosen or even fall off. At this time, the second rotating plate 707 can be rotated, and the second rotating plate 707 drives the bidirectional screw 702 to rotate. The bidirectional screw 702 drives the two sliders 704 to approach each other during the rotation process, and the two sliders 704 drive the two arc clamping plates 705 to approach each other until the two arc clamping plates 705 clamp the connection between the slurry inlet pipe 5 and the external pipe, thereby reducing the vibration generated at the connection between the slurry inlet pipe 5 and the external pipe, improving the connection strength between the slurry inlet pipe 5 and the external pipe, and reducing the probability of the connection between the slurry inlet pipe 5 and the external pipe becoming loose or even falling off. When the connection between the slurry inlet pipe 5 and the external pipe is completed, The slurry is injected into the grouting pipe body 1 through the slurry inlet pipe 5. A filter screen plate 604 is arranged in the grouting pipe body 1. The filter screen plate 604 can filter the incoming slurry to prevent some larger impurities from clogging the grouting holes 3. The filtered slurry flows out through the grouting holes 3 for grouting. When there are some impurities that block the surface of the filter screen plate 604, the first rotating plate 606 can be rotated, and the first rotating plate 606 drives the rotating rod 605 to rotate, and the rotating rod 605 drives the bristle brush 607 to rotate on the surface of the filter screen plate 604. When the bristle brush 607 rotates on the surface of the filter screen plate 604, some blocked impurities will be removed from the surface of the filter screen plate 604, thereby preventing the impurities from affecting the filtering effect of the filter screen plate 604. When there are many impurities on the surface of the filter screen plate 604 and the bristle brush 607 cannot handle the impurities, the sealing cover 601 can be rotated, and then the filter screen plate 604 is taken out from the grouting pipe body 1, so as to facilitate the treatment of impurities on the surface of the filter screen plate 604.

[0031] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
