[0001] The utility model relates to the technical field of concrete vibration, in particular to a device for assisting in vibrating and compacting concrete in a pavement void area. Background Technique
[0002] In the continuous renewal process of the city, pavement settlement, heavy traffic and other reasons will cause the phenomenon of local slab bottom voids in the concrete pavement. In order to ensure the travel safety of urban residents, it is necessary to reconstruct the damaged concrete pavement. The traditional construction process is to break and rebuild the concrete pavement or drill and grout. However, due to the incomplete compaction of the bottom concrete, the repaired pavement will still show problems such as damage and cracking after a period of time, which not only causes urban traffic congestion but also greatly increases the cost.
[0003] In addition, during the excavation construction of urban pipe networks, it is inevitable to cause the collapse or settlement of the concrete pavement base at the trench edge. Generally, concrete is used to backfill and compact the void part during the backfill construction. However, the vibrating rod cannot penetrate deep into the void area during the vibration process, resulting in incomplete compaction of the void area and then the existence of cavities, which affects the backfill quality.
[0004] Therefore, designing a simple and feasible method for dealing with incomplete compaction of deep concrete is the problem to be solved by the utility model. Content of the Utility Model

[0022] 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 the embodiments.
[0023] Referring to Figures 1-4 , a device for assisting in vibrating and compacting concrete in a pavement void area, includes a first guide rod 4 and a second guide rod. The end of the first guide rod 4 and the end of the second guide rod are connected by a universal joint 5. The first guide rod 4 is detachably connected to the middle position of the vibrating rod flexible shaft 2, and the second guide rod is detachably connected to the vibrating rod head 7.
[0024] In a specific embodiment of the present utility model, by setting the first guide rod 4 and the second guide rod, a rigid force can be applied to the vibrating rod flexible shaft 2 and the vibrating rod head 7, which is convenient for the vibrating rod head 7 to enter the pavement void area for vibration. Thus, it can achieve the effect of pouring concrete into the underlying void area and effectively vibrating and compacting it without breaking the original pavement. At the same time, not damaging the original pavement can also play the role of reducing costs; by using a universal joint 5 to connect the first guide rod 4 and the second guide rod, the effect of angle change can be achieved between the first guide rod 4 and the second guide rod, which is convenient for inserting the vibrating rod head 7 into the void area.
[0025] The second guide rod includes a rod with adjustable length composed of a first connecting rod 6 and a second connecting rod 9. By setting the second guide rod as a rod with adjustable length, it can be used to adjust the length of the second guide rod, and then the device can be extended into pavement void areas with different depths, making the device more adaptable.
[0026] One end of the first connecting rod 6 is connected to the universal joint 5, and the other end is detachably connected to the second connecting rod 9.
[0027] A number of through holes are provided on both the first connecting rod 6 and the second connecting rod 9. The first connecting rod 6 and the second connecting rod 9 are connected by bolts and nuts 10.
[0028] The spacing of the through holes on the first connecting rod 6 and the second connecting rod 9 is the same. When connecting the first connecting rod 6 and the second connecting rod 9, the through holes on the first connecting rod 6 are overlapped with the through holes on the second connecting rod 9, and at least two through holes are overlapped. Then, bolts are inserted into the overlapped through holes and tightened with nuts. At least two sets of bolts and nuts 10 are required for tightening during connection to prevent the first connecting rod 6 and the second connecting rod 9 from rotating; during adjustment, remove the bolts and nuts 10, then change the overlapped through holes of the first connecting rod 6 and the second connecting rod 9, and then fix them again with bolts and nuts 10 to complete the adjustment of the overall length.
[0029] The second connecting rod 9 is detachably connected to the vibrating rod head 7 through the guide rod fixing buckle 8. The first guide rod 4 is detachably connected to the vibrating rod flexible shaft 2 through the guide rod fixing buckle 8. The guide rod fixing buckle 8 can be a clamp. The clamps are respectively fixedly arranged on the first guide rod 4 and the second connecting rod 9, and then the corresponding clamps are used to connect the first guide rod 4 to the vibrating rod flexible shaft 2 and the second connecting rod 9 to the vibrating rod head 7. Alternatively, straps can be used for connection.
[0030] One end of the first guide rod 4 is fixedly provided with a handle 3, and the other end is connected to the universal joint 5. By providing the handle 3, it is convenient to hold and control the first guide rod 4.
[0031] Working process: Refer to Figure 4 , first adjust the length of the second guide rod according to the depth of the pavement void area. After the adjustment is completed, straighten the vibrating rod flexible shaft 2, and also straighten the first guide rod 4 and the second guide rod. Then connect the second connecting rod 9 to the vibrating rod head 7 and the first guide rod 4 to the vibrating rod flexible shaft 2. At this time, the preparation work is completed. After pouring the concrete to the concrete void pouring section 11, start the vibrating rod motor 1 and send the vibrating rod head 7 into the void area. When the second guide rod and the vibrating rod head 7 enter the void area, apply a horizontal moving force to the second guide rod by using the first guide rod 4. During this process, the second guide rod can provide rigid support for a section of the vibrating rod flexible shaft 2 close to the vibrating rod head 7, that is, it is equivalent to using the second guide rod to push the vibrating rod head 7 into the concrete void pouring section 11 under the original concrete pavement 12 for vibration compaction, achieving an effective vibration compaction effect without breaking the original concrete pavement 12 and reducing the construction cost. When the operation is completed, it is necessary to clean the vibrating rod flexible shaft 2, the vibrating rod head 7, and the first guide rod 4, the second guide rod and the universal joint 5 in time. The cleaning method can be flushing with water.
