Description

Inspection shaft lid with protective capability

Technical Field

The invention relates to the technical field of inspection well covers, in particular to an inspection well cover with protection capability.

Background

In urban construction, there are many underground pipelines, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, defense pipelines, etc., every section of the pipelines is provided with an outlet leading to the ground, the section from the pipeline to the ground is called a manhole, and the manhole is usually flush with the ground and is called a manhole cover for covering the manhole.

Firstly, as the inspection well cover has a drainage hole, the method leads to that some naughty children easily throw inflammable and explosive substances such as gun crusts and the like into the inspection well cover when adults do not notice the objects, and as the impurities at the bottom of the sewer are fermented, the method is very easy to generate inflammable and explosive gases such as methane and the like, so that great danger is brought frequently, and meanwhile, people easily drop some valuables into the sewer to influence the life of people; secondly, however, every time in the rainstorm season, the drainage system of the old urban areas of some cities is too old, the rainwater of the sewer flows into the sewer when the rainfall is too large, and strong water pressure sometimes even flushes the inspection well cover, so that pedestrians or vehicles can sink into the sewer without worrying about when walking, and the potential safety hazard is also great.
