Description

Technical Field

[0001] The utility model belongs to the technical field of manhole covers, and particularly relates to a manhole cover for municipal engineering. Background Art

[0002] There are many underground pipelines in urban construction, such as sewer pipelines, underground gas pipelines, tap water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. There should be an exit leading to the ground at regular intervals for these pipelines. The section from the pipeline to the ground is called a manhole. The manhole opening is usually flush with the ground;

[0003] There are various manhole covers for municipal engineering in the prior art. After retrieval, for example, the Chinese utility model patent with the application number CN201922075733.2 discloses "a manhole cover for municipal engineering". In this solution, "it includes a cover body, a cover seat is arranged at the bottom of the cover body, a secondary protection device is arranged on the cover seat, and a water leakage groove is opened on the cover body. For this manhole cover for municipal engineering, by arranging a secondary protection device on the cover seat at the bottom of the cover body, one end of the Geerz protection device is rotatably connected to the cover body, and the other end is clamped with a rotating rod. The rotation of the rotating rod realizes the switching between clamping limit and limit release. This secondary protection structure can play a protective role in the absence of the cover body, and its operation is simple and convenient, with strong practicability";

[0004] The foregoing solution solves the problem of "however, when there is rainwater accumulation at a certain place during heavy rain or flood, the manhole cover will be opened to facilitate better and faster drainage. But at this time, there is no obstruction at the inlet, and due to the accumulated water above or the outer cover being opened during the construction of municipal engineering and not being closed in time, people may accidentally fall in and cause casualties, mainly because there is no other protection for the manhole except the outer cover", and has certain practicability. However, the foregoing solution still has inconveniences. The manhole cover is often run over by vehicles, and being run over for a long time will cause the gap between the manhole cover and the manhole frame to increase, and then cause the manhole cover to sink seriously. This will result in a height difference between the manhole cover and the road surface, causing the road to be uneven and seriously affecting the normal passage of vehicles, which needs to be improved;

[0005] Therefore, the utility model provides a manhole cover for municipal engineering to solve the above deficiencies. Summary of the Utility Model

An embedding groove is provided inside the well frame body, and the manhole cover body is embedded in the embedding groove. It further includes a protective frame and buffer springs. A plurality of connecting columns are fixedly arranged along the circumferential direction at the bottom of the protective frame. The connecting columns penetrate through the bottom of the embedding groove, and a plurality of the buffer springs are respectively sleeved around the outer sides of the connecting columns and are located between the protective frame and the bottom of the embedding groove.

[0008] As a preferred technical solution of the present utility model, when the manhole cover body is installed in the well frame body, the bottom surface of the manhole cover body is mutually attached to the top surface of the protective frame.
