The bracket transfers the load to the pavement structural layer, avoiding direct pressure on the well body, significantly reducing the likelihood of sinking, and also lessening the pressure on the manhole.

The wellhead, well casing, and road surface are connected by socket and spigot joints, integrating the well cover frame with the road surface. This design disperses vehicle loads, prevents settlement, and offers high bearing capacity.

The manhole covers and frames are hinged together, making it difficult to be stolen without specialized breaking tools, thus serving as a theft deterrent and reducing the likelihood of stolen manholes in the city, as well as minimizing potential safety hazards for vehicles and pedestrians.

The manhole covers feature an inverted trapezoidal structure with an embedded rubber strip, which effectively reduces vibration and noise, preventing the loud sound when vehicles drive over the covers.
