Description

A sewer manhole cover structure

technical field

The utility model relates to the field of sewage drainage equipment, in particular to a sewer manhole cover structure.

Background technique

With the rapid development of the city, the manhole cover is an important symbol to record the historical changes of the city, the "gate" of the underground drainage system and the pipeline system. The common cement manhole cover, but because the cement manhole cover is easy to crack, it is not safe, and the concrete manhole cover has been produced again. However, with the increase of roads and vehicles, the safety of concrete manhole covers is also weak, so they are upgraded to cast iron manhole covers. From gray cast iron to nodular cast iron, due to the gradual increase in load bearing and high hardness, cast iron manhole covers are used more and more on the road. Ductile iron manhole covers can bear a maximum load of about 60 tons, and the application rate of manhole covers has been greatly improved. In recent years, composite resin manhole covers and stainless steel manhole covers, because of their beautiful appearance, are also a relatively good type of manhole covers developed in the manhole cover market.

Based on the above, the inventors found that the traditional manhole cover is not safe during use, and the tragedy of pedestrians falling into the sewer is prone to occur due to the loss of the manhole cover, and the urban sewer pipes emit unpleasant stench in summer, or Mosquitoes and other breeding grounds in water wells, groundwater overflows in heavy rainy days, floods all over the street, and overflows with odor, causing great troubles to the urban environment and pedestrian safety. Therefore, in view of this, research and improvement are made on the existing structure to provide a Plant a sewer manhole cover structure in order to achieve a more practical purpose.
