Description

Technical Field

[0001] The utility model belongs to the technical field of grouting anchor rods, in particular to a grouting reinforcement anchor rod device. Background Art

[0002] The use of grouting materials to reinforce coal pillars and broken surrounding rocks can improve the physical and mechanical properties of the surrounding rocks and enhance the strength of the surrounding rocks. At present, grouting anchor support methods are widely used in construction tunnels such as culverts, mines, and subways to prevent the falling of surrounding rocks and maximize the safety of the lives of on-site construction workers.

[0003] At present, common grouting anchor rods are provided with grouting ports at their ends during use, which leads to the easy entry of impurities before grouting, causing blockage and affecting the grouting effect. In addition, high-pressure grouting is performed only by relying on the pressure of the grouting machine during the grouting process. Since the pressure equipment cannot perform high-pressure grouting continuously, it is necessary to intermittently inject slurry to generate pulses. The slurry cannot be completely injected into the tiny cracks. Moreover, during the plugging process, the holes are mainly sealed by slurry stoppers and wire plugs, which leads to the outflow of slurry after the grouting is completed and the holes cannot be tightly sealed. Slurry leakage and pressure relief often occur, resulting in the insignificant grouting effect in the deep broken zone and the failure to achieve the effect of high-pressure grouting reinforcement. Therefore, it is of great significance to study a new grouting reinforcement anchor rod device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0027] like Figure 1-5As shown, the utility model provides a technical solution: a grouting reinforcement anchor device, including an anchor 1, a plurality of rod sleeves 12 are installed through the top of the anchor 1, the rod sleeves 12 can ensure the smooth passage of the push rod 6, so that the push rod 6 can push the annular sleeve 10 to move, the rod sleeve 12 corresponds to the position of the push rod 6, a grouting pipe 4 is passed through the anchor 1, the grouting pipe 4 can drain the grouting material into the anchor 1 smoothly, the grouting pipe 4 is fixedly connected in the pipe sleeve 11, the pipe sleeve 11 is installed above the anchor 1, and a compaction structure 3 is arranged above the pipe sleeve 11, and the compaction structure 3 includes a fixing seat 3 3. The fixing seat 33 is fixedly connected to the outside of the pipe sleeve 11. Two electric hydraulic rods 31 are fixedly connected to the bottom of the fixing seat 33. The bottom end of the electric hydraulic rod 31 is fixedly connected to a pressure plate 32. When the grouting material enters the anchor rod 1, the plug body 51 can be pushed upward, so that the push rod 6 passes through the rod sleeve 12 and pushes the annular sleeve 10 upward. At this time, the electric hydraulic rod 31 drives the pressure plate 32 to press down the annular sleeve 10 and the push rod 6, thereby applying pressure to the plug body 51, so that the grouting material can be compacted by applying pressure to avoid gaps between the materials, thereby maintaining compactness;

[0028] An annular sleeve 10 is provided outside the pipe sleeve 11 and below the compaction structure 3. The annular sleeve 10 can slide outside the pipe sleeve 11 so that the annular sleeve 10 can synchronously press down multiple push rods 6 to move. A one-way grouting structure 2 is provided below the grouting pipe 4 and the anchor rod 1. The one-way grouting structure 2 includes a hollow rod 22. Multiple fixing rods 25 are fixedly connected to the outside of the hollow rod 22. The hollow rod 22 can be fixed by the fixing rod 25, and the top of the hollow rod 22 is a pointed cone, thereby reducing the resistance of the grouting material. The multiple fixing rods 25 above and the fixing rods 25 below are respectively fixedly connected to the inner wall of the grouting pipe 4 and the anchor rod 1. The top of the rod 22 is a pointed cone, and a sliding rod 23 slides inside the hollow rod 22. The sliding rod 23 can ensure the stable sliding of the hollow rod 22, so that the sealing ball 21 can move smoothly. The bottom end of the sliding rod 23 is fixedly connected to the sealing ball 21. The two sealing balls 21 are respectively arranged at the bottom of the grouting pipe 4 and the anchor rod 1. The top of the sliding rod 23 is fixedly connected to the first spring 24. The upward restoring force of the first spring 24 causes the sliding rod 23 to give the sealing ball 21 an upward pulling force, so that the sealing ball 21 fits the bottom of the anchor rod 1. In this way, the bottom of the anchor rod 1 can be closed to prevent impurities from entering the anchor rod 1 and causing blockage problems, thereby ensuring smooth The grouting operation is performed, and the sealing ball 21 closes the bottom of the grouting pipe 4 to prevent the grouting material from flowing back during the compaction process. The top of the first spring 24 is fixedly connected to the upper wall of the hollow rod 22. An adjustable sealing structure 5 is provided at the lower part of the outside of the grouting pipe 4. The adjustable sealing structure 5 includes a plug body 51. A second spring 52 is fixedly connected to the top of the plug body 51. The plug body 51 can slide in the anchor rod 1 so that the plug body 51 can compact the grouting material smoothly. The second spring 52 can maintain the position of the plug body 51 so that the grouting material can pre-open the sealing ball 21 at the bottom of the anchor rod 1. The top of the second spring 52 is fixedly connected to the upper wall of the anchor rod 1. Fixed connection, the plug body 51 is arranged in the anchor rod 1, and the top of the plug body 51 is fixedly connected to multiple push rods 6. The plug body 51 slides on the grouting pipe 4. A gear rod 7 is fixedly connected to the top of the plug body 51. The grouting pipe 4 is provided with a valve 8. The valve 8 is fixedly connected to a gear 9, and the gear 9 corresponds to the gear rod 7. The plug body 51 moves upward so that the grouting material can fill the anchor rod 1, so that the plug body 51 drives the gear rod 7 upward to transmit to the gear 9, and the gear 9 drives the valve 8 to automatically close the grouting pipe 4, thereby playing a plugging role to avoid the phenomenon of slurry leakage and pressure relief. Multiple push rods 6 are connected to the adjustable sealing structure 5.

[0029] The working principle of the utility model is as follows: when grouting is performed, the grouting outer tube is connected to the grouting tube 4, and grouting can be injected into the grouting tube 4 at this time, so that the grouting material pressurizes the sealing ball 21 and discharges it from the grouting tube 4, so that the grouting material enters the anchor rod 1, and as the grouting material increases, the sealing ball 21 below can be flushed open. When the bottom hole of the anchor rod 1 is filled, the grouting material pushes the plug body 51 upward, so that the plug body 51 drives the push rod 6 to move upward, and the push rod 6 passes through the rod sleeve 12 and pushes the annular sleeve 10 to move, so that the electric hydraulic rod 31 can control the pressure plate 32 to drive the annular sleeve 10 to move downward, so that the push rod 6 presses the plug body 51 downward, so that the plug body 51 presses the grouting material to fill the gap tightly, and after filling tightly, the height of the plug body 51 is reduced. As the grouting operation continues, this process can be repeated, and finally the plug body 51 continues to move upward to drive the gear rod 7 and the gear 9 to transmit, so that the gear 9 drives the valve 8 to close the grouting tube 4, and the grouting operation can be completed at this time.
