Abstract:Through the investigation and analysis of the current rainwater drainage system in a petrochemical industrial base, the current problems are summarized. Combined with the construction and development of the base, adhering to the idea of "sponge city construction", the planning scheme of combining the gray measures with the green measures is put forward pertinently in order to improve the rainwater drainage standards in the area, which provides the scientific guidance scheme for the construction and management of subsequent rainwater projects in the base.
