Description
Technical Field
[0001] The utility model relates to the technical field of manhole grates, in particular to a rainwater manhole grate for municipal road drainage. Background Art
[0002] At present, sewers are underground passages for draining sewage and rainwater. They are indispensable drainage facilities on urban roads. Rainwater grates need to be installed on sewers. Rainwater grates are welded from flat steel and twisted square steel or flat steel and flat steel. Rainwater grates have the advantages of beautiful appearance, optimal drainage, high strength, multiple specifications and low cost.
[0003] Among them, cast iron grates are used to cover deep wells on roads or at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc.
[0004] Although the manhole grate can filter larger branches and garbage, smaller leaves and impurities will be introduced into the municipal drainage pipe along the filter frame on the manhole grate. Moreover, if the manhole grate is not opened for a long time, the manhole grate will fit firmly in the installation frame with the soil, making it difficult to open the manhole grate. Therefore, a new technical solution needs to be designed to solve the problem so that the operator can quickly open the manhole grate and quickly clean the impurities inside the municipal drainage. Utility Model Content
[0005] The utility model aims to provide a rainwater well grate for municipal road drainage, which solves the problems raised in the background technology.
