Chapter 2 - Environmental pollution and control measures of high-speed railway projects during construction period

Abstract

The impact of high-speed railway project on the environment during the construction period is mainly ecological damage and environmental pollution. Noise sources of high-speed railway project during the construction period mainly include noise generated by machinery and vehicle transportation, as well as blasting construction noise. Vibration during the construction period of high-speed railway projects is mainly generated by power-type construction machinery and equipment, heavy transport vehicles, vibration generated by pile construction, and blasting construction. This chapter introduced the regulation for noise and vibration control. Moreover, the wastewater mainly comes from the wastewater generated from construction operations, the washing water of construction machinery and transportation vehicles, and the domestic sewage generated by construction personnel. Furthermore, the exhaust gas emitted from the construction machinery, the smoke from the blasting operation, and the dust generated from the earthwork and transportation vehicles will affect the air environment near the construction site. In addition, domestic garbage generated by construction camps shall be collected and sent to the sanitation department for unified and centralized treatment, and the abandoned soil and ballast shall be transported to the designed abandoned soil site for disposal.
