城市中小河道截污主要方式和工程实例

目前上海中小河道基本未设雨、污水分流系统,不仅河道自身污染严重,而且当水量较大或汛期时,给苏州河带来极大污染。为此必须加快实施中小河道的截污纳管工程。介绍了沿河边敷设截污管道和河道内敷设截污管道的两种主要方式,以及溢流设施和玻璃钢接头的形式和具体施工。最后介绍了长宁区中小河道截污纳管工程的实例。

On Main Pollution Interception Methods to Urban Middle-small River Channels & Related Engineering Projects

There are basically no rainwater and wastewater distribution systems of Shanghai middle-small river channels at present. These channels have been not only polluted seriously but also Suzhou Creek has been polluted terribly when meeting a large amount of water or flood season. It is necessary to speed up the construction of pollution interception projects of middle-small river channels. There are 2 main methods introduced in the paper, laying pollution interception pipeline along the rivers and into the channels. Otherwise, overflow facilities and the type and detailed construction of glass fiber reinforced plastics joint are presented in the paper. Finally, the pollution interception project practice of middle-small river channels in Changning Area is put forward.
