Abstract

The utility model discloses an anti-falling down net for a manhole. The utility model comprises a manhole base. The anti-falling down net for a manhole is characterized in that the utility model is provided with a soft net bag which is connected with the manhole base. The utility model has the advantages that when a manhole cover is lost, the anti-falling down net for a manhole can efficaciously prevent pedestrians or objects from falling in the manhole; when an urban road steeps water and the water needs to be drained peremptorily, pedestrians and larger objects can be prevented from falling into the manhole even if the manhole cover is opened; the anti-falling down net for a manhole which is suitable for popularization and application has simple structure and practicability.

Description

The anti-fall net of inspection shaft

Technical field

The utility model relates to the anti-fall net of a kind of inspection shaft, is used for the port between urban Underground pipeline and the ground, prevents that pedestrian or object from crashing in the well from well head.
