Cause of Hechi sewer explosion accident

There may be a variety of comprehensive factors for the reasons of Hechi sewer explosion accident. The following are some possible reasons:

1. Aging damage of sewer pipe: Hechi sewer system was built earlier, and the service life of the pipe is longer, so there is aging damage of sewer pipe, which leads to pipeline leakage and harmful gas generation.

2. Sewage treatment is not timely: pollutants in sewers, such as organic waste, will decompose and produce harmful gases. If not handled in time, harmful gases will accumulate and increase the risk of explosion.

3. Incomplete sewer cleaning: The sewer cleaning is incomplete, and the residue and scale can gather with organic matter, resulting in explosion conditions.

4. Rainwater and temperature: When rainwater flows into the sewer, the temperature difference between hot air and cold air may also lead to an explosion. In addition, the accumulated water in the sewer will generate steam in high temperature weather, and if it is not discharged in time, it is easy to form explosion conditions.

5. Human factors: As a public facility, if the sewer is damaged or involves illegal dumping of garbage, it may lead to an explosion accident. For example, dangerous goods such as toilet water and pesticides in sewers are piled together, which may explode if they are accidentally collided or vandalized.

In a word, the cause of Hechi sewer explosion accident may be a combination of many factors, including natural factors, human factors, aging facilities and so on. It is necessary to strengthen the maintenance and management of facilities, eliminate hidden dangers in time and ensure public safety.
