Embodiment 1

[0031] A process for lifting an asphalt pavement inspection well, characterized in that the specific steps are:

[0032] 1) Use a steel plate to cover and fix the wellhead of the inspection well, pave the underlayer of asphalt concrete on the road surface of the inspection well to be lifted, and remove the underlayer of asphalt concrete above and around the inspection well in reverse, remove the steel plate, and make the inspection well A circular groove is left between the periphery and the lower layer of asphalt concrete;

[0033] 2) Clean the circular groove, then place the steel keel, and pre-fix the well seat according to the height of the well seat, and then set up the inner mold in the inspection well, and finally install it in the circular groove Pour fine stone quick-hardening high-strength concrete until it is flush with the lower layer of asphalt concrete, so as to completely cover the entire well base, and maintain it to standard strength;

[0034] 3) Brush a laye...

Abstract

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.

Description

technical field [0001] The invention belongs to the field of road construction, and in particular relates to a process for lifting inspection wells on asphalt pavement and a lifting structure thereof. Background technique [0002] Today, when environmental protection has become a global concern, urban roads in my country are undergoing black transformation. Black roads, also known as green roads, are popular among city builders and citizens for their advantages in dust prevention, pollution-free, noise reduction, and beauty. favorite. However, with the continuous improvement of road "blackening", a new problem has emerged in urban roads, that is, "road navel-inspection well". [0003] The traditional process of raising inspection wells is made of bricks. Due to the limitation of the construction period, the upper layer should be paved when the strength of the masonry does not meet the design requirements, resulting in the sinking of the well base and the cracking of th...
