Description

Technical Field

[0001] The utility model relates to the field of inspection wells, in particular to a municipal inspection well structure. Background Art

[0002] Municipal inspection wells are also called manholes. Common ones include cable manholes, communication manholes, etc. That is, for the convenience of inspection and threading, a vertical passage for people to go down is dug at intervals. With the development of the economy and the acceleration of urbanization, the infrastructure construction has been greatly promoted, and a large number of new communities and roads have appeared. As long as there are public facilities such as municipal and communications, inspection wells need to be installed.

[0003] In recent years, whenever there is heavy rainfall, major cities are seriously flooded. Underground water pipes are becoming more and more important in municipal construction. Inspection wells are set up at regular intervals in these pipes. However, when rainwater flows into the rainwater inspection wells, the rainwater will bring mud and sediment on the road surface into the inspection wells. The mud and sediment will accumulate at the bottom of the inspection wells and settle there. Over time, if these mud and sediment are not handled in time, they will affect the smooth flow of the pipelines. However, when cleaning the silt at the bottom of the pipeline, the operator needs to go down to the bottom of the well. This cleaning method is labor-intensive and it takes a long time to go down to the bottom of the well for cleaning, resulting in reduced work efficiency. At the same time, the environment at the bottom of the well is usually harsh, and there may be toxic gases, hypoxia and other problems, which can easily pose a hidden danger to the life safety of the operator.

[0004] Therefore, it is necessary to provide a new municipal inspection well structure to solve the above technical problems. Utility Model Content
