Analysis on Rainwater Regulation and Storage Scheme for Xiamenbei Railway Station Public Transport Hub

早期建设的雨水系统面临新建地块高标准排水时,由于排水能力不足容易发生内涝,而旧管通常受制于建设条件又难以改造。文章针对上述情况,对常规设地下调蓄池和设下凹绿地两种调蓄方案进行综合比选,最后确定了以设下凹绿地作为公交枢纽站项目的雨水调蓄方案,避免了花较大代价改造下游现状管,对于类似项目具有一定的参考意义。

When the rainwater system constructed in the early stage is faced with high-standard drainage of newly-built plots,it is prone to waterlogging due to insufficient drainage capacity,while the old pipes are usually constrained by construction conditions and difficult to be transformed.In view of the above situation,the two regulation and storage schemes of setting conventional underground regulation and storage tank and setting sunken green space are comprehensively compared and selected.Finally,the rainwater regulation and storage scheme with sunken green space as the public transport hub station project is determined,which avoids the transformation of the current downstream pipes at a large cost,and has certain reference significance for similar projects.
