Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, in particular to a road hollow filling device. Background Art

[0002] After the construction of concrete pavement, due to the lack of tight vibration of the base pavement, after a period of time after the surface cement material is paved, as the base pavement sinks, the surface cement material will become hollow. In addition, the thermal expansion and contraction coefficients of the surface material and the internal material are inconsistent when heated and cooled, which will also cause hollowing in the pavement after the construction of the concrete pavement.

[0003] For hollow roads, construction workers usually use drilling equipment to pre-drill holes at the locations that need to be repaired. After drilling the holes, they use grouting equipment and then insert the injection tube head into the holes to inject the repair material. However, construction workers will become tired after holding the tube for a long time, and the injection will be unstable, which may cause deviation and spillage of the material. To this end, we propose a road hollow filling device to solve the above problems. Utility Model Content
