国务院办公厅出台“关于推进海绵城市建设的指导意见”指出,采用渗、滞、蓄、净、用、排等措施,将70%的降雨就地消纳和利用。而对城市黑臭水体进行治理,可以采取截、引、净、减、调、养、测等措施。因此,景观湖泊水体整治与海绵城市建设在雨水径流控制、污染物削减、长效保持等方面有共同的建设需求及建设途径。在项目建设中将二者相结合,以此达到节约工程费用和工程效益最大化的目的。本文结合江西鹰潭东湖水体治理的工程案例,从截污纳管、初雨调蓄、就地处理、LID建设等方面,探讨海绵城市和景观湖泊水体整治的共同建设途径。
The General Office of the State Council promulgated the Guiding Opinions on Promoting the Construction of a Sponge City, pointing out that 70% of the rainfall will be absorbed and used locally by measures of seepage, stagnation, storage, net use, and pavement. While the city black and smelly water governance, you can take the cut, lead, net, reduction, transfer, support, measurement and other measures. Therefore, landscape lake water treatment and sponge city construction have common construction needs and construction approaches in rainfall runoff control, pollutant reduction and long-term maintenance. In the project construction will be a combination of the two, so as to achieve the purpose of saving project costs and maximize engineering benefits. Based on the case of East Lake water body management in Yingtan, Jiangxi Province, this paper discusses the common construction ways of water body remediation in sponge city and landscape lake from the aspects of intercepting sewage pipe, rainwater storage, local treatment and LID construction.
