Description

Technical Field

[0001] This utility model relates to the field of construction technology of asphalt concrete core walls, specifically to a vibratory compaction device for backfilling asphalt concrete core holes. Background Technology

[0002] The Kurgan Water Conservancy Project is one of the 150 major water conservancy projects during the 14th Five-Year Plan period. The project mainly consists of an asphalt concrete core dam, a right bank spillway, a right bank unpressurized flood discharge and sand flushing tunnel, a power generation water diversion tunnel, a bank-type powerhouse behind the dam, an ecological water release pipe, and fish passage structures. The asphalt concrete anti-seepage core wall needs to be tested for indicators such as density, porosity, and permeability. Core sampling of the asphalt concrete anti-seepage core wall is required, and the holes left by the core sampling need to be backfilled and compacted in a timely manner.

[0003] The existing patent authorization announcement number CN216551506U discloses a core sampling and backfilling compaction device for asphalt concrete pavement. The compaction base is extended into the core sampling hole, and the gravity sliding part can be lifted to a suitable height along the connecting part and the guide part and then fall. During the fall, the gravity sliding part collides with the force-bearing part, thereby driving the force-bearing part and the compaction base to compact the fill in the core sampling hole. Since the gravity sliding part can be lifted to the required height, the compaction base has a good compaction effect each time, effectively reducing the number of compaction times, thereby reducing the input of personnel and time.

[0004] When using the above-mentioned patent, construction workers need to support the outside of the guide component with one hand to ensure its stability and uprightness and prevent it from tilting or falling. During the compaction process, the gravity sliding component needs to be lifted manually. It is inconvenient to operate the gravity sliding component with one hand, especially when the gravity sliding component is heavy. It is not easy to use, lacks flexibility, and has certain limitations. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides a technical solution: a vibratory compaction device for backfilling asphalt concrete core holes, comprising a guide rod 1, a compaction base 2, a force-bearing stop 3, and a counterweight 4. The compaction base 2 is disposed at the bottom of the guide rod 1. A stabilizing component 5 is movably installed on the outside of the guide rod 1, located between the compaction base 2 and the force-bearing stop 3. The stabilizing component 5 includes a ring sleeve 51 movably sleeved on the outer wall of the guide rod 1. Three supporting crossbars 52 are fixedly connected to the outer wall of the ring sleeve 51, arranged in a ring at equal intervals. The ends of the three supporting crossbars 52 away from the ring sleeve 51 are all... A support vertical rod 53 is fixedly connected, and a support foot 54 is fixedly installed at the bottom of each support vertical rod 53. A rubber pad 55 is fixedly installed at the bottom of each support foot 54. The compaction base 2 is vertically placed into the core hole and placed on the backfilled asphalt mixture. At this time, the rubber pad 55 installed on the support foot 54 at the bottom of the support vertical rod 53 is located on the ground around the core hole. The construction worker can step on the support horizontal rod 52 on one side with one foot to keep the guide vertical rod 1 stable and avoid tilting or falling. This allows the worker to free up both hands to operate the counterweight hammer 4, making it suitable for single-person use and improving flexibility.

[0024] The inner side of the ring sleeve 51 is provided with multiple grooves 56 at equal intervals in a ring shape. Each groove 56 is movably engaged with a ball bearing 57. The ball bearing 57 fits against the outer wall of the guide rod 1, which can effectively reduce the frictional resistance between the ring sleeve 51 and the guide rod 1. When the construction personnel operate the counterweight 4 to move the guide rod 1 up and down, the ball bearing 57 rolls in the groove 56, so that the ring sleeve 51 can slide more smoothly along the guide rod 1, avoiding the impact of jamming on the continuity of the vibration operation. At the same time, it can also reduce the wear between components and extend the service life of the stabilizing component 5.

[0025] The guide rod 1 includes a lower guide rod 11 and an upper guide rod 12. Threaded holes 13 are provided at both the upper and lower ends of the lower guide rod 11. The upper guide rod 12 is threaded to the top of the lower guide rod 11. The compaction base 2 is threaded to the bottom of the lower guide rod 11. The force-bearing stop 3 is fixedly installed on the outer side wall of the lower guide rod 11. The counterweight 4 is set on the upper guide rod 12. The compaction base 2 and the threaded holes 13 at the bottom of the lower guide rod 11 are screwed together and fixed. Then, the upper guide rod 12 and the threaded holes 13 at the top of the lower guide rod 11 are screwed together and fixed. The modular assembly structure makes it more flexible to use. At the same time, the appropriate compaction base 2 can be flexibly selected according to the core hole for operation.

[0026] The force-bearing stop 3 is fixed to the outside of the lower guide rod 11 with bolts. Multiple mounting holes are vertically and equidistantly arranged on the lower guide rod 11, so that the height of the force-bearing stop 3 can be adjusted according to the usage.

[0027] During backfilling and compaction, debris and water droplets in the core hole are cleaned and dried with a blowtorch. The perimeter of the hole is heated to above 70°C. Then, the asphalt mixture is backfilled in layers. The compaction base 2 is placed vertically on the backfilled asphalt mixture inside the core hole. By stepping on the support bar 52 with one foot and lifting the counterweight 4 to the target height with both hands, the counterweight 4 is allowed to fall freely. The counterweight 4 impacts the force-bearing stop 3 and applies force to the compaction base 2 to compact the asphalt mixture. This process is repeated multiple times to make the asphalt mixture compacted and dense.

[0028] The counterweight 4 includes a main counterweight 41 and multiple secondary counterweights 44. The main counterweight 41 is movably sleeved on the outer wall of the upper guide rod 12. A handle 42 is fixedly connected to the outer wall of the main counterweight 41. A limiting rod 43 arranged in a ring symmetrically is fixedly connected to the top of the main counterweight 41. The multiple secondary counterweights 44 are stacked and sleeved on the outer wall of the upper guide rod 12. The interior of each secondary counterweight 44 has through holes corresponding to the limiting rods 43. Through the cooperation of the through holes and the limiting rods 43, the multiple secondary counterweights 44 can be stably stacked on top of the main counterweight 41, preventing displacement during stacking. Both the main counterweight block 41 and the secondary counterweight block 44 have through holes in their centers that match the diameter of the upper guide rod 12, ensuring that the counterweight hammer 4 can slide smoothly along the upper guide rod 12. The main counterweight block 41 and the secondary counterweight block 44 are designed according to standard specifications. When it is necessary to adjust the overall weight of the counterweight hammer 4, the number of secondary counterweight blocks 44 can be increased or decreased according to the actual vibration requirements. The operation is simple and quick, and it can effectively adapt to the vibration force requirements of backfilling operations for core holes of different depths and sizes. The handle 42 makes it convenient for operators to hold and control the lifting and lowering of the counterweight hammer 4, further improving the convenience and stability of the device during use.

[0029] The outer wall of the upper guide rod 12 is marked with a starting point for the fall. The mark adopts a conspicuous circular scale design, which can intuitively show the initial fall position of the counterweight 4 when it is vibrating. The operator can quickly raise the counterweight 4 to the standard height and release it by observing the mark, so as to ensure that the fall height of each vibration is consistent, effectively avoiding the problem of uneven vibration force caused by human operation differences, thereby ensuring the uniformity of the density of the backfill material in the core hole and improving the stability of the backfill construction quality.

[0030] Please see Figure 1 , Figure 3 and Figure 4A fixing hole 14 is provided on the outer wall of the lower guide rod 11, and a limiting hole 58 is provided on the outer wall of the ring sleeve 51. The limiting hole 58 is adapted to the diameter of the fixing hole 14. A wing bolt 15 is installed in the internal thread of the fixing hole 14. Two of the three support crossbars 52 are fixedly connected to the outer walls of their ear plates 59. The ear plates 59 are located at the end away from the ring sleeve 51. A movable wheel 510 is rotatably mounted on the outside of the ear plates 59. When it is necessary to move to the next core hole position, the upper... Lifting the upper guide rod 12 causes the lower guide rod 11 and the compacted base 2 to rise together. Unscrew the wing bolt 15, align the fixing hole 14 and the limiting hole 58, and screw the wing bolt 15 into the fixing hole 14 through the limiting hole 58 to limit the position of the stabilizing component 5. Tilt the guide rod 1 towards the ear plate 59 so that the moving wheel 510 outside the ear plate 59 touches the ground. Pulling the upper guide rod 12 will drive the moving wheel 510 to roll on the ground, making it easy to move and reducing labor intensity.

[0031] The fixing hole 14 is located on the outer wall of the lower guide rod 11 near the end of the compaction base 2. The moving wheel 510 is made of rubber, which has good elastic cushioning performance to prevent the device components from loosening due to bumps when moving on uneven ground. The fixing hole 14 is located close to the compaction base 2, so that the connection point between the stabilizing component 5 and the lower guide rod 11 is closer to the bottom of the device. This enhances the stability of the overall structure during movement and prevents tipping due to the shift of the center of gravity. After moving to the target core hole position, simply straighten the guide rod 1 so that the compaction base 2 is in contact with the ground again, unscrew the wing bolt 15 to adjust the stabilizing component 5 to a suitable height, and then screw the wing bolt 15 into the fixing hole 14 to fix it. The device can then be restored to its working state. The operation process is smooth and convenient to improve construction efficiency.

[0032] Working principle: When in use, the ring 51 is sleeved on the outside of the lower guide rod 11, and the tamping base 2 corresponding to the core hole is screwed and fixed to the threaded hole 13 at the bottom of the lower guide rod 11. Then, the upper guide rod 12 is screwed and fixed to the threaded hole 13 at the top of the lower guide rod 11. The tamping base 2 is inserted into the core hole and placed vertically on the backfilled asphalt mixture. At this time, the rubber pad 55 installed at the bottom of the support foot 54 of the support rod 53 is located on the ground around the core hole. The construction personnel can stabilize the guide rod 1 by stepping on the support crossbar 52 on one side to prevent tilting and falling. By grasping the handle 42 on the outside of the main counterweight 41 with both hands, the main counterweight 41 and the auxiliary counterweight 44 installed on the top are lifted upwards to the target height and then allowed to fall freely. The counterweight hammer 4 impacts the force-bearing stop 3 and applies force to the tamping base 2 to tampe the asphalt mixture. By repeating this process multiple times, the asphalt mixture is tamped and compacted. Then, the core hole is repeatedly backfilled and tamped in multiple layers.

[0033] When backfilling and compacting multiple core holes in the area, and moving to the next core hole position, the upper guide rod 12 is lifted to move the lower guide rod 11 and the compaction base 2 upward. The butterfly bolt 15 is unscrewed and the fixing hole 14 is aligned with the limiting hole 58. The butterfly bolt 15 is screwed into the fixing hole 14 to limit the position of the stabilizing component 5. Then, the guide rod 1 is tilted and tilted towards the ear plate 59 to be laid down, so that the moving wheel 510 on the ear plate 59 side contacts the ground. By pulling the upper guide rod 12, the moving wheel 510 can be driven to roll on the ground, which facilitates movement and reduces labor intensity. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
