The present invention relates to a manhole, and more particularly, by allowing the internal space of the collecting box in which the waste water is stored, to be variably increased through the corrugated pipe, even if a large amount of the waste water is introduced intensively. The present invention relates to a sewer pipe manhole retrofit structure that can prevent the overflow of the sump box or backflow.

In general, the manhole is buried in the basement of the road or sidewalk is made of a round or square shape so that the worker can enter and maintain the maintenance of rainwater, water and sewage drainage, telecommunications facilities. Among the manholes constructed on the road, the water supply manhole is mainly used to branch the water supply pipe, and the sewer manhole treats the wastewater generated in the building adjacent to the road.

Sump manholes in which sewage flows out of these manholes are used to treat water generated in buildings, rainwater generated on roads, and groundwater generated from the bottom of buildings.

1 is a perspective view showing a conventional manhole.

The manhole 10 includes a water collecting box 20 embedded in the road at a predetermined depth, and a lid 30 that opens and closes an upper portion of the water collecting box 20.
