Problems solved by technology

At present, most of the round manhole covers are made of cast iron, which is heavy and does not fit tightly with the road surface. When the vehicle runs over the tires and collides with the manhole cover, it is easy to generate noise pollution.
Aluminum alloy formwork technology has developed rapidly and has entered the stage of large-scale application, but its application in manhole covers has not been reported yet

Abstract

The invention relates to a manhole cover, comprising a manhole cover mount and a manhole cover panel nested in the manhole cover mount; the manhole cover mount is a rectangular frame formed by welding four first aluminum profiles, the manhole cover panel is composed of a panel component and a frame component, the panel component is formed by welding two or more U-shaped aluminum profiles or flat aluminum profiles side by side, and the frame component is composed of four second aluminum profiles arranged respectively on four edges of the panel component. The manhole cover provided herein is wholly made of aluminum alloy profiles and has the advantages such as light weight, simple structure, convenience of processing, high bearing capacity, tight connection with a pavement and rarity of producing noise pollution.

Description

technical field [0001] The invention relates to the technical field of road facilities, in particular to a manhole cover. Background technique [0002] With the development of construction technology and the requirements of energy conservation and environmental protection, people have higher requirements for the quality of urban road administration projects, and higher requirements for the flatness of the ground. At present, most of the round manhole covers are made of cast iron, which is heavy and does not fit tightly with the road surface. When the vehicle runs over the tires and collides with the manhole cover, it is easy to generate noise pollution. Aluminum alloy formwork technology has developed rapidly and has entered the stage of large-scale application, but its application in manhole covers has not been reported yet. Contents of the invention [0003] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the pres...
