If there are a large number of heavy and overloaded vehicles in urban traffic, it will damage the well and its surroundings.
Secondly, it is also possible that the planning and layout of pipeline engineering in the range of motor vehicle lanes is not reasonable. Or the structure around the well must have different settlement due to their own weight and vehicle load.
