Polygonal inspection well cover support

Abstract

The invention provides a polygonal inspection well cover support. The horizontal height of the polygonal inspection well cover surface can be adjusted by adjusting the polygonal inspection well coversupport. When the asphalt pavement is paved or shoveled on the cement pavement or the asphalt pavement is shoveled, the polygonal inspection well cover surface is kept flat with the finished pavementmacroscopically by increasing and decreasing the polygonal inspection well cover support so that a comfortable and safe road environment can be obtained when vehicles pass. The impact of vehicle driving on the polygonal inspection well cover and the polygonal inspection well wall can be kept at the least set value, the maintenance interval of the polygonal inspection well cover and the polygonal inspection well wall can be prolonged and the road maintenance and repair expenses can be reduced.

Description

[0001] Technical field [0002] The invention relates to a polygonal (including quadrangular and more polygonal) inspection well cover support which can keep the polygonal (including quadrilateral and more polygonal) inspection well cover surface level with the road surface macroscopically. Background technique [0003] It is obvious to all that the common polygonal manhole covers on the road surface either obviously protrude from the road surface or are sunken under the road surface; a series of adverse consequences are caused immediately. For example, when a vehicle passes over a protruding or concave polygonal inspection well cover, it will cause bumps, and the goods may be displaced on the vehicle, which may seriously cause the vehicle to overturn; the driver often slows down and passes through the protruding or concave polygonal inspection well. cover, or turn to avoid the protruding or concave polygonal manhole cover, and the traffic accidents caused by this are not unco...

[0003] It is obvious to all that the polygonal inspection well covers that are common on the road either protrude obviously from the road or are sunken under the road; then a series of adverse consequences are caused

For example, when a vehicle passes over a protruding or concave polygonal inspection well cover, it will cause bumps, and the goods may be displaced on the vehicle, which may seriously cause the vehicle to overturn; the driver often slows down and passes through the protruding or concave polygonal inspection well. cover, or turn to avoid the protruding or concave polygonal manhole cover, and the traffic accidents caused by this are not uncommon; The degree of the surface or the depression increases. Under the continuous abnormal impact, the polygonal inspection well cover or the inspection well wall will eventually be broken, resulting in damage to the road surface and even damage to the underground pipeline.
