源头径流控制系统是海绵城市建设内容的重要组成部分之一,包含渗、滞、蓄、净、用、排等多种低影响开发设施及其组合,对实现城市良性水文循环,提高雨水径流的渗透、调蓄、净化、利用和排放能力,维持恢复城市的“海绵”功能等的作用不可或缺。目前我国海绵城市建设取得了长足进步,但设施运行维护规程还不成熟,缺少相应的运行维护体系。为此对源头径流控制设施维护过程中关于责任分配、维护人员要求、维护要点等问题进行了探讨,对海绵城市源头径流控制设施的健康长久运行具有重要意义。
The source-runoff control system is one of the important components of sponge city construction. It includes various low-impact development facilities and their combinations such as seepage, hysteresis, storage, net, use and drainage and other combinations. It is of great significance to realize the urban virtuous hydrological cycle and improve the runoff of rainwater The role of infiltration, regulation, purification, utilization and emission, maintenance of the city’s “sponge” functions is indispensable. At present, great progress has been made in the construction of sponge city in our country, but the operation and maintenance procedures of the facilities are not yet mature and the corresponding operation and maintenance system is lacking. In order to solve the problems such as responsibility distribution, maintenance personnel requirements and main points of maintenance during the maintenance of source runoff control facilities, this paper is of great significance to the healthy long-term operation of spontaneous runoff control facilities in sponge cities.
