Cause of manhole cover explosion

There are many reasons for manhole cover explosion. The main reasons include the following aspects:

1. Gas leakage: There may be gas leakage in the sewer pipe. If you encounter an open flame or an electric spark, it will cause an explosion.

2. Extreme weather: Under extreme weather conditions, such as extremely dry conditions, the organic matter in the sewer is prone to spontaneous combustion, which will lead to fire and manhole cover explosion.

3. Changes of groundwater level: In some areas, the groundwater level is high, and it is difficult to remove the accumulated water in the sewer, which is easy to form a certain pressure. If there is an explosion, the pipe will burst and the manhole cover will fly.

4. Heavy vehicle pressure: In some areas, the road traffic is busy, and large vehicles often drive on the manhole cover, resulting in the aging and deformation of the manhole cover, which leads to the failure of the manhole cover. If there is an explosion, the manhole cover is easily washed away.

5. Violent destruction: In some areas, there may be some illegal acts that destroy public facilities, such as smashing manhole covers with heavy objects. If the manhole cover itself is not good enough, it is easy to explode.

Generally speaking, the cause of manhole cover explosion is complicated, which is the result of many factors. In order to avoid this situation, it is necessary to strengthen the maintenance and management of sewer network, repair aging sewer pipes and manhole covers, timely investigate gas leakage and other issues, raise public safety awareness, and strengthen supervision and law enforcement.
