Negative influence of urban rail transit connection

Impact of noise and vibration during construction 1 impact of pollution during construction on city appearance and municipal administration. The main pollution sources of noise and vibration during construction are various large excavators, transport vehicles, air compressors, drilling machines, pile drivers, various blasting operations and road rolling operations. A large number of demolition and road rolling operations will cause the surface vegetation to be destroyed, exposing the surface land, and windy weather will cause dust. At the same time, various construction vehicles will also produce a lot of secondary dust, which will aggravate the air pollution in the city. This vegetation was destroyed and the topsoil was exposed. If it is rainy, it is very easy to cause soil erosion. Moreover, the open-cut cover excavation section of the underground section is large, which will produce a lot of waste soil. Water storage places are naturally formed in the excavation section in rainy season, which has caused slope collapse and affected the construction degree and smooth roads. In particular, the surface runoff caused by heavy rain washed away the exposed soil bureau and the loose structure of the construction horizon. These washed and polluted atmospheric precipitation forms turbid muddy water, which generally contains garbage, dirt, sediment and oil, and is a negligible pollution source. In addition, these large amounts of abandoned soil and other construction wastes on the ground also form a large number of solid wastes. Third, the impact on the city appearance and municipal administration during the construction period. Construction occupies urban roads and brings convenience to the lives of urban people. Construction will occupy part of the roads where the original vehicles pass, forcing some vehicles to be diverted, which will only waste people's travel time and bring a sudden increase in traffic pressure to other nearby expressways. In addition, the construction will inevitably affect the underground pipelines in municipal engineering, which will bring inconvenience to the surrounding residents in water, electricity, heating or communication.
