Description

Sewer well lid structure

Technical Field

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

Background

With the rapid development of cities, well covers are important marks for recording the historic transition of cities, and are the 'gates' of underground drainage systems and pipeline systems. Common cement well covers, but because the cement well covers are easy to crack, the cement well covers are unsafe and concrete well covers are produced. However, as roads increase, vehicles have increased, and the safety of concrete well covers has also been weak, so that the concrete well covers are upgraded to cast iron type well covers. From gray cast iron to nodular cast iron, the bearing of the cast iron manhole cover is slowly improved, the hardness is high, and the cast iron manhole cover is increasingly used on roads. The highest spheroidal graphite cast iron well lid can bear about 60 tons, and the application rate of well lid improves by a wide margin. In recent years, composite resin well covers and stainless steel well covers are also good well covers developed in the well cover market due to attractive appearance.

Based on the above, the present inventors found that: in the use of traditional well lid, its security is not good, and the tragedy that the well lid lost and lead to the pedestrian to drop into the sewer easily appears, and urban sewer gives off foul smell in summer moreover, or breeding such as the mosquito of sewer, runs into big rainy day groundwater and overflows, and the crossing of water crossing in the street, foul smell overflows, causes very big puzzlement for urban environment and pedestrian safety, then, has the reason to this, to the current structure research improvement, provides a sewer well lid structure to the purpose that has more practical value is reached.
