Description

Technical Field

[0001] The utility model belongs to the technical field of building construction auxiliary equipment, and in particular relates to a system for recycling wastewater and rainwater at a construction site. Background Art

[0002] With the development of cities, the amount of construction water and natural precipitation at construction sites is very large. In order to reduce the impact of construction on the urban environment, vehicles entering and leaving the construction site will also need to clean and remove dust from the body and tires.
