Inspection well protection cover plate and pavement asphalt laying construction method applied by inspection well protection cover plate

Abstract

The invention discloses an inspection well protection cover plate and a pavement asphalt laying construction method applying the same, and belongs to the technical field of inspection well construction, the inspection well protection cover plate comprises a shielding plate, and is characterized in that a positioning frame is arranged at the lower end of the shielding plate; the positioning frame comprises four independent round rods which are distributed at the lower end of the shielding plate in an annular array mode. A cushion block is arranged at the lower end of the shielding plate; the cushion blocks are distributed at the lower end of the shielding plate in an annular array; a drawable lifting handle is arranged at the upper end of the shielding plate; the handle comprises a lifting rod, a sliding rod and a check block. The lifting rod is arranged above the shielding plate, the sliding rods are fixedly arranged at the two ends of the lifting rod, and the lifting rod and the sliding rods form a U-shaped rod; a sliding hole is formed in the shielding plate, and the sliding rod is in sliding fit with the sliding hole; the lower ends of the sliding rods are fixedly connected with check blocks. Compared with the prior art and a traditional construction process, the problems that the curtain board is easily dragged and shifted by a paver and the paving flatness of asphalt around a well is influenced during asphalt paving operation are solved, and the method has the characteristics of improving the working efficiency and reducing the construction cost.

Description

technical field [0001] The invention relates to the technical field of inspection well construction, in particular to an inspection well protection cover plate and a pavement asphalt paving construction method thereof. Background technique [0002] When paving asphalt at the inspection wells on municipal roads, the usual practice is: when paving the underlying layer of asphalt, use protective shields to protect the wellhead. Pave the top layer of asphalt. However, the simple protective shield cannot be fixed when it is covered at the inspection wellhead. When the asphalt is paved, the pushing force of the asphalt driven by the paver will drag and displace the protective shield, causing the asphalt material to leak into the well; and the crawler track The pressure of rolling the protective shutter is very large, and the contact area under the protective shutter is small, which will damage the protective shutter; when the asphalt lower layer is paved, the upper layer will con...
