摘要
以广州市司马涌、荔湾涌和西濠涌为例,分析总结了深层隧道排水系统在城市防洪排涝和控制溢流污染方面的应用。指出深层隧道排水系统避开了拥挤的浅层地下空间,具有征地拆迁量少,对地面交通和建筑影响小,可实施性好等优点,是城市老城区排水改造的可行方案。同时,深层隧道排水系统必须与局部浅层改造相结合,才能发挥最大的效益。
Taking Sima River,Liwan River and Xihao River of Guangzhou as an example,the article analyzes and sums up the application of deep tunnel drainage system in urban flood control,drainage and overflow pollution control,and points out that the deep tunnel drainage system keeping away from the crowded shallow underground space has the advantages of a little land acquisition demolition,a little influence on ground traffic and buildings and good feasible for implementation.It is the feasible scheme for the drainage reconstruction of old urban area.Also the deep tunnel drainage system must be only combined with the partial shallow reconstruction,and can play the maximum benefit.
