Description

Concealed manhole decorative cover plate structure

Technical Field

The utility model belongs to the technical field of the technique of road manhole and specifically relates to a stealthy manhole dress trim cover plate structure, in particular to its mechanical connection structure.

Background

The general materials of current road surface paving manhole apron keep unanimous with the road surface paving, in order to ensure the intensity of the apron of mating formation, generally be at the all cladding metal frame of mating formation, metal frame and the obvious contrast of the material of mating formation on every side, at any time the lapse of time, metal frame can age and fade, influence the pleasing to the eye of shop front, in addition, for routine maintenance, can set up hoisting structure on the surface of mating formation, the hoisting structure stability that sets up on the surface is poor, easy damage, the event still needs to carry out further improvement to current manhole surface mating structure.

Disclosure of Invention

An object of the utility model is to provide a stealthy inspection shaft dress trim cover plate structure. Overcomes the defects in the prior art.

In order to realize the purpose, the technical scheme of the utility model is that: a concealed manhole decorative cover plate structure comprises a manhole, wherein the manhole is buried underground, the cross section of the manhole is approximately in a convex structure, the top of the manhole is provided with an access hole, the access hole is covered with a cast iron cover plate, the upper part of the cast iron cover plate is covered with a decorative cover plate, a gap is formed between the decorative cover plate and the cast iron cover plate, the upper layer of the decorative cover plate is a cover plate paving layer, the lower layer of the decorative cover plate is a stainless steel plate, a steel wire mesh is covered between the cover plate paving layer and the stainless steel plate, stone glue is filled in the steel wire mesh, the surface of a steel wire of the steel wire mesh is rough, the lower surface of the stainless steel plate is provided with a plurality of keel square tubes, the keel square tubes are distributed in parallel and equidistant distribution at the lower surface of the stainless steel plate, the keel square tubes are welded at the lower surface of the stainless steel plate, four corners of, the lower end face of the hanging ring is welded with the upper surface of the stainless steel plate, the upper end face of the hanging ring forms a closed end face, and a strip-shaped opening is formed in the closed end face.

The utility model discloses a stealthy inspection shaft dress trim cover plate structure, dress trim cover plate have sufficient intensity by layer, corrosion resistant plate, fossil fragments side's pipe of mating formation, have replaced current formula project organization of borduring, simultaneously, adopt embedded hoisting structure, the structure is more stable, and is not fragile. The design scheme is simple in structure and high in practicability, and the paving cover plate and the surrounding pavement are integrated.
