Description

Technical Field

[0001] The utility model relates to the technical field of municipal power well structures, and particularly to an invisible manhole cover type wellhead structure for a power well. Background Art

[0002] Power pipelines are usually buried in urban roads. The power pipelines are used to accommodate urban power transmission lines. The power pipelines need to be arranged with power wells at intervals. The power wells provide passages for the power pipelines, facilitating workers to enter the wells to repair the power transmission lines in the power pipelines. With the continuous development of the city, the original urban roads no longer meet the needs of urban development. The upgrading and reconstruction of the old and new urban roads are based on the original road system. During the upgrading process of the old and new urban roads, the original power well structure cannot meet the new road requirements. For example, the manhole cover of the power well is easy to protrude from the road surface, the manhole cover is made of different materials from the new road, the manhole cover cannot meet the requirements of road zoning (such as blind paths, sidewalks, bicycle lanes, etc.), and the aesthetics is poor, and the bearing capacity of the manhole cover is insufficient; and many power wells in the roads cannot be completely demolished during the upgrading process of the old and new urban roads. Therefore, in order to adapt to the construction or renewal of urban roads, an wellhead structure that can make the manhole cover structure meet the road requirements and is suitable for the transformation of old wells is needed.
