摘要（英）：

The utility model relates to an egg shape inspection well, which is composed of manhole 1 and an air hole 2. The external form of the utility model is in an egg shape. The utility model is characterized in that the manhole 1 is in an egg shape; the air hole 2 is elliptical or circular; the manhole 1 and the air hole 2 are parallel and can directly lead into a well. The shape of the well mouth conforms to human bodies' features and can meet the operation requirements of climbing up wells and climbing down wells; when the circular shape is changed into the egg shape, the size of the utility model is shrunk and the utility model can be favorable to protect the inspection well and sewers.
