Research on Applicable Technology of Sponge Transformation of Old Residential Quarters Based on SWMM
In order to solve the problem of waterlogging in the old community,this paper put forward the applicable tech-nology of sponge transformation for different types of old community.Taking an old community in Xiaoshan District as an example,the rainwater runoff model was established by SWMM to verify the feasibility and effectiveness of this tech-nology.Aiming at the characteristics of poor infrastructure and high underlying surface hardening rate of this residential district,appropriate LID facilities were selected to conduct sponge transformation and simulate its stormwater regulation effect under different rainfall recurrence periods.The results show that the number of overload nodes can be effectively controlled,which can ensure that the long-term water accumulation will not occur in the community under the maximum rainfall intensity of once in 20 years.The total runoff in the study area is significantly reduced and the regional waterlog-ging capacity is greatly improved after the renovation of LID combination facilities by applying this technology.
