Technical Field
The utility model relates to a road construction appurtenance field, in particular to guarantee to prevent subsiding instrument of asphalt concrete compactness under well lid.
Background
As shown in fig. 1, a manhole cover 2 on a road surface is used for covering a shaft 3, and two fabrication holes 1 are formed in the manhole cover 2. In the prior art, when a paver is used for paving, a layer of asphalt mixture is directly paved on the whole pavement (including a well cover). In the process of paving the asphalt surface layer of the municipal road, the anti-settling well cover needs to be synchronously lifted along with the asphalt surface layer; the synchronous lifting can reduce the running water beat and shorten the construction period. But can appear the problem in current well lid synchronous lifting work progress:
firstly, the paver paves behind the well lid of traveling, can only look for the well lid with the visual method, can not confirm the position very first time, and this will cause at the in-process of looking for, and the continuous bituminous mixture who looks for the pre-compaction that turns over with the spade, even after the later stage flattening, also can cause the mixture local range in the volume of paving inhomogeneous to it is unqualified to cause the compactness around the well lid.
And secondly, the quantity of the mixture to be filled when the inspection well cover is lowered to the bottom is not measured. Usually, a mixture is manually filled under the well lid by using a shovel, and the well lid is 1-2cm higher than the surrounding pre-pressing surface after the mixture is fully filled, but the height can only be determined by feeling due to different thicknesses of the upper, middle and lower surface layers. The upper surface layer is designed to have the thickness of 4cm, if the well lid is 1-2cm higher than the surrounding asphalt surface, the well lid is higher than the surrounding asphalt surface after the rolling is completed, the flatness is influenced, and if the well lid is strongly vibrated to be leveled, the mixture can be shattered, so that the bearing capacity of the well lid is reduced; the well cover at the middle and lower layers is higher than 1-2cm, because the mixture is turned over, the compaction coefficient is different from that of the mixture pre-pressed at the periphery, and the mixture under the well cover is not enough in compaction degree after the disturbed mixture is filled and rolled. The above reasons can cause the insufficient intensity of the asphalt mixture under the well cover or around the well cover, and the bearing capacity is reduced.
