《城镇雨水调蓄工程技术规范》解读

Interpretation on Technical code for urban stormwater detention and retention engineering

《城镇雨水调蓄工程技术规范》(GB 51174-2017)将于2017年7月1日起正式实施,是对国内外雨水调蓄工程实践经验的总结,规范了我国城镇雨水调蓄工程的规划、设计、施工和运行,有利于推动雨水综合管理技术的发展。介绍了规范的编制背景和思路,明确了调蓄的定义和分类等概念,并对其中涉及的调蓄系统设计、多功能雨水调蓄设施和雨水调蓄工程安全高效运行等主要内容进行了阐述,有助于对该规范的理解。

The national standard, Technical code for urban stormwater detention and retention engineering（GB 51174-2017）, is a summary of domestic and international experience of urban stormwater detention and retention engineering （USDR）. As a guide for the planning, design, con- struction and operation of USDR, the national standard is conducive to promoting the development of integrated stormwater management technology. The background and thought of the national standard were introduced, and the concepts of definition and classification of USDR were also clear- ly defined. For better understanding, several key technologies such as USDR system design, multi- functional USDR facilities, safe and efficient operation were further discussed.
