Why do many housekeepers cannot control a manhole cover?

The manhole cover is the covert project of the municipal public infrastructure hidden under the rain and water, and it is the entrance to these concealed works.

Everyone knows that the news of the girl falling from the well in Changsha was under heavy rain, cold and rainy nights, an accidental slippage, and the girl fell into an endless darkness. She drifted in the icy water for nearly 60 kilometers and was discovered 60 days later. In this wonderful time, she bid farewell to the world in the most unbearable manner.

Just a few days ago, a 2-year-old child accidentally crashed into a kiln well and died when he was playing. "More than 500 meters long outside the ring west road, there are more than 60 wells on both sides of the green belt." Citizen Wu Chuangui said, wells hidden in the green belt, since construction, has not been covered by the lid. Two hours after the incident, staff from different departments came to the scene one after another. “About 40 well covers were installed.” What is even more chilling for the family is that the accident passed more than six hours. In addition to civilian police on the scene, no one else came forward to handle the matter.

Are the tragedies caused by the manhole cover. Why are the manholes covered without covers? Are some thieves stolen? Perhaps it is, but is it just to save money on this, regardless of the safety of the people? According to investigations, most of the pipeline property owners have failed to perform inspections on the management of roads and wells. They have not been repaired in a timely manner. Internally there has been a lack of effective supervision and punishment, and problems have been criticized. As a result, a problem has not been discovered and repaired for a long time since the manhole cover had a problem. Even some of the pipeline property units do not have full-time maintenance teams and either carry out the work outsourcing or temporarily hire team maintenance.

Is it not possible to set up a second line of defense about 75 cm below the manhole cover? This will neither delay the decline of the water flow nor delay the daily maintenance. If the manhole cover is stolen, if the man falls, there will be a second protection that can save lives.
