[0002] When installing the manhole ring of the inspection well, the elevation of the manhole ring is generally controlled by a level. When the manhole ring elevation is inconsistent, a commonly used method is to add pads to the bottom of the manhole ring. Due to the different shapes and sizes of the pads, the pads are easy to slide or fall off, so that the position of the manhole ring changes after the manhole ring is elevated, resulting in inaccurate manhole ring elevation. Because the manhole ring elevation is inconsistent, it is easy to be crushed by passing vehicles, causing damage to the manhole ring and manhole cover, reducing the service life of the manhole ring and manhole cover, and greatly increasing the amount of later maintenance.
