Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a municipal drainage ditch manhole cover. Background Art

[0002] A gutter cover, also known as a gutter cover or ditch cover, is a covering installed on a gutter. Its main function is to protect the gutter from the intrusion of external substances, such as garbage, debris, etc., while ensuring that water can flow smoothly, helping to prevent drainage channels from being blocked and reducing the risk of urban waterlogging.

[0003] Traditional manhole covers are mostly made of high-strength, corrosion-resistant materials with good compression and impact resistance. However, the leakage holes on the manhole covers are large, and impurities such as leaves and garbage bags on the road surface can easily enter the manhole covers with rainwater. The impurities gather together and easily cause blockages, especially small impurities such as pebbles and cigarette butts, which directly enter the drain ditch. Small amounts accumulate and easily affect the normal drainage of the drain ditch. Utility Model Content
