Description

Technical Field

[0001] The utility model relates to the technical field of grouting devices, in particular to a grouting device for karst pipelines in hydropower stations. Background Technique

[0002] Grouting of karst pipelines in hydropower stations refers to the process of grouting the pipeline system of hydropower stations under karst geological conditions, aiming to reinforce the rock strata around the pipelines, fill cracks and voids, enhance the stability and sealing performance of the pipelines, and ensure the safe operation of the pipelines. Most of the currently used grouting equipment is a grouting machine.

[0003] A patent with the current publication number CN219387214U discloses a grouting machine, which includes a mobile base, universal wheels, a fixed frame, a storage tank, a material guiding port, a feeding valve, a slurry guiding groove, a servo motor C, a spiral feeding rod, and a grouting pump. Universal wheels are rotatably arranged at the four corners of the bottom of the outer wall of the mobile base through bearings. A fixed frame is fixedly installed at the top of the outer wall of the mobile base. A storage tank is fixedly installed at the bottom of the outer wall of the fixed frame. The material guiding port is embedded at the bottom of the outer wall of the storage tank. When the device avoids the setting of static concrete slurry, the staff opens the feeding valve, and a large amount of concrete slurry is introduced into the slurry guiding groove through the material guiding port. Then, the servo motor C is turned on to drive the spiral feeding rod to rotate and convey a large amount of concrete slurry to the other end of the slurry guiding pipe and then into the grouting pump. The staff then turns on the grouting pump to spray the concrete slurry from the grouting head at the other end of the grouting hose into the cracks of the building concrete floor for grouting repair.

[0004] However, the following problems still exist in the above grouting machine:

[0005] When the grouting machine is in use, the mixed cement mortar is often transported from the grouting pipeline to the pipeline construction site that needs to be filled through the grouting pump. However, after the construction is completed, because the cement mortar usually has a certain viscosity and is cleaned slightly slowly, it will cause solidification and caking in the grouting pipeline, thereby affecting the subsequent grouting effect.

[0006] In response to the above situation, the method of cleaning the grouting pipeline is mostly to separate and remove the grouting pipeline from the equipment, and then clean the inside of the grouting pipeline. However, this method is not only cumbersome to operate, but also takes a long time. Especially in some construction areas with higher temperatures, it is very likely that during the disassembly period, some mortar will cake in the pipeline, resulting in an increase in the cleaning difficulty, which is rather inconvenient.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Please refer to Figures 1-6 , a karst pipeline grouting device for a hydropower station, including a grouting machine body 1, a support block 2 installed on one side of the grouting machine body 1, and a grouting pipe 3 installed inside the support block 2. The upper surface of the grouting pipe 3 is communicated with a connecting pipe 5. One side of the connecting pipe 5 is fixedly connected and communicated with an inlet slurry pipe 6. A storage cavity 501 is penetrated and opened on the upper surface of the connecting pipe 5. The inner wall of the storage cavity 501 is connected with a flushing water pipe 4. The lower end of the flushing water pipe 4 penetrates the storage cavity 501 and the sliding pipe 9 and is communicated with a water spraying pipe 12. A plurality of water spraying holes 1201 are penetrated and opened on the outer wall of the lower end of the water spraying pipe 12. The upper surface of the outer wall of the connecting pipe 5 is fixedly connected with a cylinder 7. The output shaft of the cylinder 7 penetrates the outer walls of the connecting pipe 5 and the sliding pipe 9 and is fixedly connected with the upper surface of the water spraying pipe 12.

[0025] The karst pipeline grouting device in the present utility model is similar in structure to the existing karst pipeline grouting device for a hydropower station, such as the karst grouting and reinforcement drill with the model number: zjl - 350. As Figures 1 through 6As shown, when the karst pipeline grouting device in the utility model is in use, first connect the external concrete mortar pipe to the slurry inlet pipe 6. Then, insert the grouting pipe 3 into the position of the karst pipeline that needs to be grouted through the grouting machine body 1. Subsequently, start the normal grouting operation. After grouting the karst pipeline, only need to control the grouting pipe 3 to be pulled out from the grouting position of the karst pipeline, and then transfer it to a suitable position. At this time, turn on the cylinder 7 through the external controller. After the cylinder 7 starts, it pushes the water spray pipe 12 to descend. When the water spray pipe 12 descends, it will drive the external sliding pipe 9 to descend, and then the slurry inlet pipe 6 can be blocked through the sliding pipe 9, so as to avoid the flushing sewage from entering the external concrete mortar pipe during flushing. Then, without disassembling the grouting pipe 3, connect the end of the flushing pipe 4 far from the water spray pipe 12 to the external water pump. Then, suck in the flushing water through the external water pump and spray it out from the several water spray holes 1201 of the water spray pipe 12, so as to flush the inside of the grouting pipe 3, and then avoid the situation that the inside of the grouting pipe 3 caking due to spending too much time on disassembly.

[0026] It should be particularly noted here that: the external concrete mortar pipe, the external water pump and the external controller are all very mature existing technologies, so no detailed description will be given.

[0027] Please mainly refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, several sliding grooves 901 are opened on the outer wall of the sliding pipe 9, and several sliding rails 10 are fixedly connected to the inner wall of the connecting pipe 5. The outer walls of the several sliding rails 10 are respectively slidably connected to the inner walls of the several sliding grooves 901. By setting the sliding grooves 901 and the sliding rails 10, the up and down movement track of the sliding pipe 9 can be restricted, so that it is not easy to deviate and tilt.

[0028] Please mainly refer to Figure 4 As shown, anti-detachment plates 11 are fixedly connected to the bottom surfaces of the several sliding rails 10, and the upper surfaces of the anti-detachment plates 11 are in contact with the bottom surface of the sliding pipe 9. By setting the anti-detachment plates 11, the sliding pipe 9 can be prevented from falling from below the sliding rails 10.

[0029] Please mainly refer to Figure 6 As shown, a sliding cavity 902 is opened on the inner wall of the sliding pipe 9, a sliding plate 13 is fixedly connected to the upper surface of the water spray pipe 12, and the outer wall of the sliding plate 13 is slidably connected to the inner wall of the sliding cavity 902. The height of the sliding cavity 902 from the bottom surface of the sliding pipe 9 is greater than the height of the water spray holes 1201.

[0030] More specifically, by setting the sliding cavity 902 and the sliding plate 13, when the cylinder 7 retracts, the water spraying pipe 12 will be pulled upward. At this time, the water spraying pipe 12 will slide in the sliding cavity 902 through the sliding plate 13. When the sliding plate 13 moves up to the top surface of the sliding cavity 902, several water spraying holes 1201 will be exactly located inside the sliding pipe 9, and thus the sliding pipe 9 can block the several water spraying holes 1201, avoiding the concrete mortar flowing into the slurry inlet pipe 6 from blocking the water spraying holes 1201.

[0031] After that, the cylinder 7 drives the water spraying pipe 12 to continue moving upward. At this time, the sliding plate 13 will simultaneously push the sliding pipe 9 upward until the sliding pipe 9 disengages from the blockage of the slurry inlet pipe 6. Until then, the cylinder 7 stops, and thus the next grouting can be carried out through the slurry inlet pipe 6.

[0032] Please mainly refer to Figure 2 and Figure 3 , a fixed pipe 8 is fixedly connected to the upper surface of the connecting pipe 5. The fixed pipe 8 is communicated with the connecting pipe 5, and the inner wall of the fixed pipe 8 is fixedly connected to the outer wall of the water flushing pipe 4. By setting the fixed pipe 8, a support can be provided for the water flushing pipe 4 to prevent the water flushing pipe 4 from sliding into the connecting pipe 5 and causing blockage inside the connecting pipe 5. It should be specifically noted here that: one end of the water flushing pipe 4 located in the receiving cavity 501 is a bellows hose.

[0033] Please mainly refer to Figure 2 and Figure 3 , the inner wall of the upper end of the grouting pipe 3 is threadedly connected to the inner wall of the lower end of the connecting pipe 5. By setting the grouting pipe 3 and the connecting pipe 5 to be threadedly connected, when components such as the cylinder 7, the water flushing pipe 4, the sliding pipe 9, and the water spraying pipe 12 are damaged or blocked, the connecting pipe 5 and the grouting pipe 3 can be separated very conveniently and quickly.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
