[0002] There are 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 to the ground at every section. The section from the pipeline to the ground is called a manhole. The manhole opening is usually flush with the ground, so a cover is needed. The cover used to cover the manhole is called a manhole cover.

[0003] The manhole covers on existing roads are often made of cement or steel, which makes them very heavy. In order to facilitate the movement of the manhole covers, some manhole covers are installed with rollers at the bottom. This will cause the rollers to contact the manhole seat when the manhole cover is installed on the manhole seat. The weight of the entire manhole cover is pressed on the rollers, which can easily cause damage to the rollers and is not conducive to moving the manhole cover when disassembling and installing it. For this reason, we propose a manhole cover that is easy to move. Utility Model Content
