[0002] The double-layer manhole cover is an ordinary manhole cover with an additional layer of protective sub-cover. The double-layer manhole cover protects the precision instruments underneath the manhole cover, and can also provide functions such as heat preservation and fall prevention. Double-layer manhole covers are generally used in cable wells.

[0003] The manhole covers currently on the market have the following problems when used:

[0004] 1. When the traditional manhole cover is used again, when closing the manhole cover, the sub-manhole cover is generally placed directly into the frame first, and then the main manhole cover is covered. There is no fixed structure between the sub-manhole cover and the sewer well, which is not stable enough when placed and is prone to shaking;

[0005] 2. After the traditional manhole cover is closed, since most of the manhole covers are used on the road, when there are many vehicles passing by, the manhole cover will bounce up with the passing of the vehicles, and it is easy to move for a long time, which is not convenient to use.
