Description

Technical Field

[0001] The utility model relates to the technical field of municipal road construction, in particular to a grouting device for municipal roads. Background Art

[0002] In municipal road construction, grouting is a common reinforcement method used to reinforce road surfaces, foundations, etc. to improve their bearing capacity and stability. During the grouting process, hole drilling is one of the key steps, which involves the operations of hole layout and drilling. The design of hole layout and the operation of drilling are crucial for ensuring the uniform distribution of grouting materials and the reinforcement effect.

[0003] After retrieval, the patent document with the publication number: CN220643744U discloses a grouting device for road construction. By setting the combined use of a pipeline storage mechanism and a pipeline adjustment mechanism, the device can automatically comb the overly long grouting pipes, effectively avoiding the situation where the grouting pipes are cross-wound and affect the use during the grouting operation. At the same time, the use of the pipeline adjustment mechanism can effectively ensure the flatness and uniformity of the stored pipelines, avoiding the situation where the pipelines are involved and cannot be used, greatly improving the practicability of the device.

[0004] During the actual use process, after hole drilling, the grouting head needs to be placed into the hole to facilitate the injection of the slurry into the gap. However, the above device is operated by hand, and the arm is prone to soreness during the long-term grouting process. Moreover, after the above device is used, the remaining slurry, especially the cement slurry added with a quick-setting agent, may solidify in the grouting equipment and may also cause blockage of the grouting pipeline.

[0025] Inside the slurry bucket 2, there is a partition fixedly connected. The partition divides the slurry bucket 2 into two areas. Inside the slurry bucket 2, there is a motor 6 fixedly connected. The top of the output shaft of the motor 6 penetrates the outer wall of the partition and is fixedly connected to the bottom of the vertical pipe 3. The motor 6 drives the vertical pipe 3 to rotate. Inside the U-shaped base 1, there is a centrifugal pump 14 fixedly connected.

[0026] On the outer wall of the U-shaped base 1, there is a placement block 15 fixedly connected. On the outer wall of the placement block 15, there is a placement hole. Inside the inner wall of the placement hole, there is a circular pipe 16 slidably connected. On the outer wall of the circular pipe 16, there is a ring 17 fixedly sleeved. The bottom of the ring 17 is in contact with the top of the placement block 15. The placement block 15 supports the ring 17 and the circular pipe 16, providing a supporting function to facilitate the carrying and moving of the circular pipe 16.

[0027] On the top of the slurry bucket 2, there is a telescopic mechanism. The telescopic mechanism includes a water inlet pipe 7. On the top of the slurry bucket 2, there is a sliding hole. The inner wall of the sliding hole is slidably connected to the outer wall of the water inlet pipe 7. The inner wall of the vertical pipe 3 is slidably connected to the outer wall of the water inlet pipe 7. The top of the vertical pipe 3 is mechanically sealed. After the water inlet pipe 7 slides into the vertical pipe 3, it blocks multiple water outlet holes 4. On the top of the slurry bucket 2, there is an annular block 8 fixedly connected. On the outer wall of the annular block 8, there are two threaded holes. Inside the inner walls of both threaded holes, there are bolts 9 threadedly connected. One end of the bolt 9 is rotatably connected through a bearing to an arc-shaped pressing piece. The outer wall of the arc-shaped pressing piece is pressed against the outer wall of the water inlet pipe 7.

[0028] On the top of the water inlet pipe 7, there is a hose 10 fixedly communicated. On the outer wall of the slurry bucket 2, there is a slurry inlet pipe 11 fixedly communicated.

The centrifugal pump 14 operates to pump the slurry in the slurry barrel 2 into the slurry outlet pipe 18, and the slurry is discharged through the conical slurry outlet head 19 to fill the gap below the hole. After the grouting of the road is completed, when cleaning the remaining slurry in the slurry barrel 2, rotate the slurry outlet pipe 18 to move it upward to relieve the extrusion of the plurality of conical blocks 20, take out the round pipe 16 from the hole, rotate the two bolts 9 to move the two arc-shaped extrusion pieces outward to release the position fixation of the water inlet pipe 7, move the water inlet pipe 7 upward by a certain distance to expose the plurality of water outlet holes 4, the water pump 13 operates to transport the clear water in the water storage tank 12 into the water inlet pipe 7, the clear water enters the vertical pipe 3 and is discharged through the plurality of water outlet holes 4, and as the motor 6 drives the vertical pipe 3 to rotate, the vertical pipe 3 rotates to drive the water outlet holes 4 to rotate, so that the water flow ejected from the water outlet holes 4 impacts the inner wall of the slurry barrel 2 to clean the remaining slurry. The centrifugal pump 14 operates to transport the mixed water in the slurry barrel 2 into the slurry outlet pipe 18 for discharge to clean the inside of the slurry outlet pipe 18.
