[0002] During the long-term use of the water diversion tunnel of the hydropower station, some cracks will appear, causing water leakage. In order to solve this problem, the leakage channel will be closed after the source of leakage is treated. The main method is to backfill and consolidate grouting within 20m of the water diversion tunnel on the upstream and downstream sides of the plug and at the plug, so as to cut off the leakage and prevent it from continuing to leak. In this process, a grouting reinforcement device will be used for grouting.
[0003] During the use of the traditional syringe grouting device, not only the grouting liquid needs to be manually sucked into the device, but also it needs to be manually discharged. Therefore, its working efficiency is low and a lot of manpower is wasted. In addition, during the grouting process, workers need to hold the grouting device by hand to prevent the device from falling, which will further lead to labor waste. In order to solve the above problems, a hydropower station water diversion tunnel rapid grouting reinforcement device is urgently needed to solve the above problems. Utility Model Content

[0028] The extrusion assembly 4 includes a motor 41, the output shaft of the motor 41 is fixedly connected to a threaded rod 42, the outer wall of the threaded rod 42 is threadedly connected to an extrusion block 43, the bottom end of the threaded rod 42 is fixedly connected to a first bevel gear 44, one side of the first bevel gear 44 is meshed with a second bevel gear 45, and one side of the cavity 2 is fixedly connected to an extrusion tube 47, and a screw rod 46 is provided in the extrusion tube 47.
[0029] One end of the screw rod 46 is fixedly connected to the second bevel gear 45, and one end of the extrusion tube 47 is fixedly connected to a plurality of joints 48, one end of one portion of the joints 48 is provided with a plug 49, and the other portion of the joint 48 is fixedly connected to the delivery tube 410, the threaded rod 42 is rotatably connected to the through hole opened at the top of the cavity 2, the extrusion block 43 is slidably connected to the inner wall of the cavity 2, the screw rod 46 is rotatably connected to the through hole opened in the support seat 6, and the inner cavity of the extrusion tube 47 is communicated with the inner cavity of the cavity 2;
[0030] The specific implementation method is as follows: when performing the grouting operation, the extrusion block 43 is raised to the highest point and the grouting liquid is added to the cavity 2, and the plug 49 at one end of the joint 48 is opened as needed and the corresponding delivery pipe 410 is fixed to it, and then the insertion component 5 is inserted into the grouting hole, and the motor 41 is started. The output shaft of the motor 41 rotates to drive the threaded rod 42 to rotate, thereby driving the extrusion block 43 to move downward and squeeze the space in the cavity 2, thereby squeezing the grouting liquid into the extrusion pipe 47. At the same time, the rotation of the threaded rod 42 drives the first bevel gear 44 to rotate, thereby driving the screw rod 46 to rotate through the second bevel gear 45, thereby further squeezing the grouting liquid into the joint 48, so that the grouting liquid enters the insertion component 5 through the delivery pipe 410 and is sprayed out. The assembly can reduce the workload of workers, thereby reducing their labor intensity.

Open the plug 49 at one end of the joint 48 as needed and fix the corresponding delivery pipe 410 to it. Then extend the grouting pipe 55 and the mounting bracket 54 into the grouting hole. Then, rotate the conical block 51 to move it into the mounting bracket 54 and squeeze the slider 52 so that it moves and contacts the inner wall of the grouting hole, thereby increasing the friction between it and the grouting hole. Start the motor 41, and the output shaft of the motor 41 rotates to drive the threaded rod 42 to rotate, thereby driving the extrusion block 43 to move downward. The space in the cavity 2 is squeezed, thereby squeezing the grouting liquid into the extrusion tube 47. At the same time, the rotation of the threaded rod 42 drives the first bevel gear 44 to rotate, thereby driving the screw rod 46 to rotate through the second bevel gear 45 to further squeeze the grouting liquid into the joint 48, so that the grouting liquid enters the grouting pipe 55 through the delivery pipe 410 and is sprayed out. At the end of grouting, the conical block 51 is reversed to move it out of the mounting bracket 54 and separate it from the slider 52 to avoid it blocking the slider 52, thereby driving the slider 52 to separate from the grouting hole by moving the shift block 53, thereby taking out the grouting pipe 55.
