摘要
为了解决老旧小区内涝问题,针对不同类型的老旧小区提出了海绵化改造的适用技术,以萧山区某老旧小区为例,利用SWMM建立雨洪径流模型验证了该技术的可行性和有效性.针对该小区基础设施差、下垫面硬化率高等特点,选择适用的LID设施对其进行海绵化改造并模拟其在不同降雨重现期下的雨洪调控效果.结果表明,超载节点数量得到有效控制,可保证在最大20年一遇的降雨强度下该小区不发生长时间积水.应用该技术选用LID组合设施进行改造后,研究区域径流总量显著降低,区域排涝能力得到极大提升.
Abstract
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.
