From the calculation results in the above table, we can see that the range of daytime construction machinery exceeding the standard is within 100m, and the range of night construction machinery exceeding the standard is within 600m. Construction work is prohibited for night piling machines/concrete vibrators and woodworking machinery. For other construction machinery, construction during the day The over-standard range of machinery is 15m, and the noise limit for construction operations can be reached at night when it is 50m away. There are no environmentally sensitive targets such as residential areas within 1km outside the plant boundary of the project, and construction noise has a small impact on environmentally sensitive targets.
