Description

Technical Field

[0001] This utility model relates to the field of municipal road construction technology, and in particular to a safety protection device for manhole openings in municipal road construction. Background Technology

[0002] Safety protection devices for manholes in municipal road construction are protective measures designed to ensure the safety of the construction site and prevent pedestrians and vehicles from accidentally falling into the manholes. These devices are particularly important in urban construction and maintenance, as they are directly related to public safety and the safety of construction workers.

[0003] Existing safety protection devices for manholes used in municipal road construction require the bottom ring of the device to be inserted into the manhole opening, with the outer wall of the bottom ring fitting snugly against the inner wall of the manhole. While these devices prevent pedestrians or vehicles from accidentally falling into the manhole, the bottom ring is not properly secured. In severe weather, the loosely secured bottom ring can easily detach from the manhole, affecting the warning effect. Therefore, this solution proposes a new safety protection device for manholes used in municipal road construction to address these issues. Utility Model Content
