海绵城市源头工程设施运行维护管理技术体系研究

Study on Technical System of Operation,Maintenance and Management of Source Engineering Facilities in Sponge City

我国海绵城市工程设施的运行维护管理是当前亟需重视的问题。针对国内现有的不同雨水设施的运行维护需求,提出了科学运行维护管理的技术体系,如日常巡护制度、运行效能监测和衰减性能监测。其中,运行效能监测主要是观测雨水设施运行过程中对径流峰值和污染物总量的调控。当雨水设施运行效果不达标时,应及时进行设施的衰减性监测。通过对雨水设施的介质土表征测试、沉积物积累测试和表面渗透性测试等步骤,评估雨水设施当前的衰减程度,并根据设施的衰减程度进行针对性维护。同时,运用物联网等技术建立智慧海绵动态管控系统,保证雨水设施持久有效运行,由此实现了运行维护指标体系的系统化,以期为今后我国海绵城市运行维护提供有力的技术支撑。

The operation and maintenance management of engineering facilities for sponge city is an urgent problem in China.According to the operation and maintenance requirements of different stormwater facilities in China,the technical system of scientific operation and maintenance management is proposed:daily patrol system,operation efficiency monitoring and attenuation performance monitoring.Among them,the operation efficiency monitoring is mainly to observe the regulation of runoff peak value and total amount of pollutants during the operation of stormwater facilities.When the operation effect of the stormwater facilities is not up to the standard,the attenuation monitoring of the facilities shall be carried out in time.The current attenuation degree of the stormwater facilities is evaluated through the steps of characterization test of medium soil,sediment accumulation test and surface permeability test,and corresponding maintenance is carried out according to the attenuation degree of the facilities.Meanwhile,the intelligent sponge dynamic management and control system is established by using Internet of Things and other technologies to ensure the sustainable and effective operation of stormwater facilities.Therefore,the systematization of the operation and maintenance index system is realized,in order to provide strong technical support for the operation and maintenance of sponge cities in China in the future.
