High-strength inspection well lid for urban road

Abstract

The invention discloses a high-strength inspection well lid for an urban road. The high-strength inspection well lid comprises a hard plastic grating plate and a concrete layer. Cross reinforcing strips are welded to the upper surface and the lower surface of the hard plastic grating plate. The cross reinforcing strips comprise the first hard plastic reinforcing strips and the second hard plastic reinforcing strips. The first hard plastic reinforcing strips and the second hard plastic reinforcing strips are arranged along the two diagonals of the plastic grating plate respectively. The hard plastic grating plate and the cross reinforcing strips serve as a framework of the concrete layer. The hard plastic grating plate and the cross reinforcing strips are covered with the concrete layer. By the adoption of the mode, the high-strength inspection well lid is simple and reasonable in structure, low in price and high in strength.

Description

technical field [0001] The invention relates to the technical field of inspection well covers, in particular to a high-strength inspection well cover for urban roads. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section. Called the inspection well, the inspection well mouth is usually flush with the ground, so a cover is needed to cover the inspection well, which is called the inspection well cover. [0003] For safety considerations, general manhole covers are all made of metal, which is expensive and stolen. Therefore, some places use plastic manhole covers, but the strength of plastic manhole covers is not enough, and there are potential safety hazards. Contents of the invention [0004] The technical problem mainly sol...

Problems solved by technology

[0003] For safety considerations, the manhole covers are generally made of metal, which is expensive and stolen constantly. Therefore, plastic manhole covers are used in some places, but the strength of plastic manhole covers is not enough, and there are potential safety hazards.
