Municipal well lid combination structure

Abstract

The invention discloses a municipal well lid combination structure. The municipal well lid combination structure comprises galvanized steel outer sleeves, reinforced concrete supports, a well lid anda galvanized steel inner sleeve. The well lid comprises a fixed lid and a movable lid. The two ends of the fixed lid are placed on the reinforced concrete supports. The lower portion of the movable lid is provided with the galvanized steel inner sleeve. Vehicle load borne by the well lid is transferred to the reinforced concrete supports through the galvanized steel inner sleeve and the galvanizedsteel outer sleeves. The galvanized steel inner sleeve can be freely inserted into the galvanized steel outer sleeves. Operators can conduct underground pipe laying and maintenance operation by opening the movable lid of the well lid. The municipal well lid combination structure has the beneficial effects that the municipal well lid combination structure is stable, not prone to deformation and breakage, high in anti-pressure ability and free of settlement, and the inner sleeve in the middle can effectively prevent people from falling off.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a municipal manhole cover assembly structure. Background technique [0002] Manhole covers are important facilities in municipal roads, usually to prevent people or objects from falling, and to collect rainwater, sewage and other functions. Usually, the manhole cover is round, and its diameter is usually 500mm-1000mm. It can be used in various environments such as green belts, sidewalks, motor vehicle lanes, and alleys. As a result, many problems such as deformation, sinking, and depression of the manhole cover are caused, which in turn cause safety hazards such as traffic accidents and pedestrians falling. For example, the manhole cover floats in the rainy season and people fall into the deep well. [0003] Many researchers propose to transform the structure of the well cover to solve the safety hazard of the well cover, for example: CN105201022A has reported a kind o...

Problems solved by technology

Usually, the manhole cover is round, with a diameter of 500mm-1000mm. It can be used in various environments such as green belts, sidewalks, motor vehicle lanes, alleys, etc. Especially in motor vehicle lanes, there are often problems of different settlement degrees between the road and the edge of the manhole cover. As a result, various problems such as deformation, sinking, and sag of the manhole cover are caused, which in turn lead to safety hazards such as traffic accidents and pedestrian falls. For example, the manhole cover floats in the rainy season and people fall into the deep well

[0003] Many researchers propose to transform the structure of the well cover to solve the safety hazard of the well cover, for example: CN105201022A has reported a kind of highly adjustable well cover structure; CN108086359A has reported the well cover structure for municipal engineering, but these cannot completely solve the road and well cover edge settlement degree Different problems, to avoid the existing security risks
