Process for lifting asphalt pavement inspection well and lifting structure
The invention discloses a process for lifting an asphalt pavement inspection well and a lifting structure. According to the process, cast-in-situ hard high-strength concrete with fine stones is adopted between the upper part of a lower structure layer of a to-be-lifted inspection well and an asphalt concrete surface layer to increase the height of the inspection well; steel keel, a cushion block and the like are arranged in front of the cast-in-situ hard high-strength concrete with fine stones to further ensure the height of a well base, so that the elevation of the constructed and molded inspection well lid is consistent with that of a surrounding asphalt concrete pavement; and the flatness is controlled within 5mm. According to the process, the upper load is supported by strength of solidified reinforced concrete, and the mass defect of well base sinking is thoroughly improved; when the well base is cushioned by the cast-in-situ hard high-strength concrete with fine stones, the elevation is adjusted by the fluidity, so that improvement of the road flatness is facilitated; and the driving comfort is met.
