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...

Examples

Embodiment 1

[0037] Please refer to Figure 1 to Figure 4 Shown, embodiment one of the present invention is:

[0038] A well cover, comprising a well cover base frame 1 and a well cover panel 2 sleeved in the well cover base frame 1;

[0039] The manhole cover seat frame 1 is a rectangular frame composed of four first aluminum profiles 10 welded end to end in sequence. 100 at the top and extend horizontally to the first stopper 101 of the manhole cover seat frame 1, the first support part 102 arranged at the top of the first main body part 100 and horizontally extended to the outside of the manhole cover seat 1 and the first support part 102 arranged at the first main body part 100 The bottom end and the first wedging part 103 extending horizontally to the outside of the manhole cover frame 1;

[0040] The well cover panel 2 is composed of a panel assembly 20 and a frame assembly 21. The panel assembly 20 is composed of two or more U-shaped aluminum profiles 200 welded side by side. The...
