What are the causes of urban road collapse?
2 Answers
There are many reasons for road collapse, which may be due to continuous heavy rain or excessive traffic, but ultimately it is due to excessive surface load, such as over-concentration of population and dense tall buildings. Continuous heavy rain: The reason why continuous heavy rain can cause collapse is that long-term soaking by rainwater can loosen the roadbed, leading to local collapse, just like the heavy rain in Henan, which will definitely cause road collapse accidents. Preventing road collapse: Of course, the relevant departments have also made great efforts to prevent road collapse, such as using radar to detect road cavities, inspecting and repairing old pipelines, and monitoring road settlement and pipeline deformation, which are also means of prevention.
As an ordinary person who drives in the city every day, I've noticed that road collapses often occur at busy intersections or near factories, mainly because there are too many heavy trucks and buses constantly exerting loads that exceed the road's designed capacity. Additionally, aging underground pipelines, such as leaking water pipes that soften the foundation, make the road more prone to collapse when rainwater accumulates and erodes cavities. Vehicle oil leaks or chemical spills can also corrode materials, accelerating deterioration. Once after rain, I drove over a sunken spot where my tire almost got stuck—fortunately, I slowed down in time. This reminds us of the need to regularly inspect pipelines to reduce risks, and urban departments must prioritize road network maintenance to prevent accidents. Maintaining roads properly is crucial for our safe driving.
