城市河渠保护与综合整治技术在大东湖项目中的应用

Applications of protection and comprehensive improvement technologies for urban river and channel to Dadonghu Lake Project

对大东湖生态水网工程中的城市河渠保护与综合整治技术进行了总结分析。根据对典型工程青山港渠、罗家港渠、东沙湖渠的具体分析,重点对渠道的平面形态及结构型式、河渠护岸的材质与型式、河渠缓冲带的采用进行了探讨。同时,根据大东湖生态水网工程实施后的实际情况对其效果进行了评估,对河渠保护和综合整治技术在大东湖水网项目的应用进行了总结,供其他河湖治理工程借鉴。

The protection and comprehensive improvement technologies for urban river and channel applied to the Project of EcoWater Network of Dadonghu Lake are summarized and analyzed herein. In accordance with the specific analyses made on the typical projects of Qingshangang Channel,Luojiagang Channel,Dongshahu Channel,the plane morphologies and structural patterns of the channels,materials and shapes of the bank protections for the rivers and channels,the buffer zones of the rivers and channels therein are emphatically discussed. Meanwhile,the effect of the Project of Eco-Water Network of Dadonghu Lake is evaluated according to the actual situation after the implementation of it,and then the applications of the protection and comprehensive improvement technologies for river and channel to the Project of Eco-Water Network of Dadonghu Lake are summarized as well,so as to provide some references for the applications of the key technologies to the other projects of river and lake improvements.
