Conceptual planning and design of sponge campus-taking the south campus of puwan campus of dalian vocational and technical college as an example

Abstract

This article fully understands the goals and requirements of the national guidance to promote the construction of sponge cities. The author fully understands the current situation of research and construction of rainwater management, sponge cities and sponge campuses in domestic and foreign cities. Based on the natural and artificial environment characteristics of the South Campus of the Puwan Campus of Dalian Vocational and Technical College (hereinafter referred to as the campus), this article focuses on the prevention of waterlogging in the rainy season and the collection and utilization of rainwater in the campus, and follows the concept of LID, and proposes a sponge campus "2 principles→4 blocks" →8 sub-items" conceptual planning and design plan. Through the conceptual design of small, source and decentralized control facilities such as permeable pavement, sunken green space, ecological grass ditch, rainwater garden, and underground storage structure, the author constructs a simulation of nature through in-situ collection, natural purification, and replenishment of groundwater.
