白云区江高截洪渠流域治涝方案比选分析

由于江高截洪渠流域的水沥村、塘贝村、泉溪村、新楼村及双岗村等高田区的雨水需穿过泉溪支流、茅山新庄支流及新楼支流各处铁路涵排向原截洪渠,而铁路涵的断面比较小,高田区的雨水不易排出,导致内涝。为解决江高截洪渠流域的排涝问题,通过3个规划治涝方案进行比选,从征拆范围、施工难度及工程投资等方面考虑,确定合理的治涝方案,解决江高截洪渠流域高田区排涝不畅问题。

Comparison and Analysis of Waterlogging Control Schemes for Baiyun Jianggao Interception Channel Basin

Because rainfall in the high land area of the Jianggao interception channel basin has to pass through the Quanxi River railway culvert, Maoshanxinzhuang River railway culvert and Xinlou River railway culvert, and then flows into the interception channel, but the railway culvert is relatively small, they can hardly drain and easily become waterlogging. In order to solve the waterlogging problem, three schemes of waterlogging control have been compared on the basis of demolition scope, construction difficulty and project investment considerations, and finally a reasonable scheme is determined to solve the waterlogging problem of Jianggao interception channel.
