Expressway of Water Supply-Design of Urban Water Supply Network of Ningbo City

根据城市“供水高速公路”模式的原理、特点,针对宁波市城市发展中存在的地域不确定性,在国内首次采用了供水高速公路的模式,借助环网“中转站”功能,有效地解决了宁波市远期的供水需求,优化了城市供水管网,提高了管网的适应能力和安全度,减少了管网的重复建设和改造频率,为国内大中城市管网建设作出了新的尝试,提出了新的思路。

According to the principle and featu re of WSE mode,the Water Supply Expre ssway Mode is firstly applied for Ningbo Ci ty owing to its regional uncertainty of development.By means of function of'intermediate repeater'of WSE ring network,the Ningbo City' s requirement of long-term water will be met effectively,the ad aptability and safety of network will be optimized,repetitive con-struction and frequency of reconstr uction can also be reduced.A new atte mpt was taken for the water supply network construction of dome stic large and medium cities.
