分流制雨水系统混接问题的调研技术体系

Investigation Technology Study on Non-stormwater Entries into Separate Storm Drainage System

针对分流制雨水系统的雨污混接、与相邻圩区排水系统串通、地下水入渗等非雨水混接问题,构建了包含沿线调查、管线检测等技术手段的分流制雨水系统混接问题调研技术体系,并以此体系为指导,调查清楚了典型排水区域(上海闵行区莘庄地铁北广场、兰坪)的混接问题,为雨水系统的改造和维护提供了可靠依据。

Aimed at the non-stormwater entries into separate storm drainage system, such as wastewater flowing, connection with adjacent drainage systems, infiltration of underground water and so on, an investigation technology system on the non-stormwater entries into separate storm drainage system was established, including survey along pipeline, internal inspection of pipeline and other technical means. Based on the investigation technology system, the non-stormwater entry problems in the representative drainage areas were investigated to provide reliable basis for reconstruction and maintenance of separate storm drainage system.
