摘要
为解决感潮河网地区污水提质增效和内涝治理难题,以广州市中心城区某城中村为研究对象,按照“源头溯源、污涝共治、雨水分流、管网提标、泵闸强排”的综合治理思路,对工程范围内所有排口进行精准溯源,结合排水单元达标创建,实现排水单元和公共管网的雨污分流改造,释放污水和雨水通道;对雨水管渠过流能力进行评估,通过开挖和非开挖修复措施,实现管网升级改造,并结合一体化泵闸的建设,解决内涝点受潮汐顶托逢雨必涝的困境,为相关感潮河网地区污涝同治建设提供参考和借鉴。
To solve the problems in the improvement of quality and efficiency of the sewage and the treatment of waterlogging in the tidal river network area,taking a village-in-city in the central urban area of Guangzhou as the research object,according to the comprehensive treatment ideas of“source tracing,sewage and waterlogging co-treatment,rainwater separation,pipeline network standard upgrade,and pump and gate forced drainage”,the sources from all outlets in the engineering range are accurately traced.Combined with the standard upgrading and establishment of drainage units,the rainwater and sewage separation and reconstruction of drainage unit and public pipeline network are realized.The sewage and rainwater pipelines are released.The discharge capacity of rainwater pipe channel is evaluated.Through the excavation and trenchless restoration measures,the upgrading reconstruction of pipeline network is realized.And combined with the construction of pump and gate integration,the problem that the waterlogging points are subject to tide and rain is solved,which provides the reference for the co-treatment construction of sewage and waterlogging in the tidal river network areas.
