浅谈娄门下穿改造项目的雨水设计

The Preliminary Study on Rainwater Design of Loumen Underpass Reconstruction Project

随着城市道路建设不断发展,新建成的高架越来越多,与现状道路上跨交叉,势必存在交叉部分的道路净空不够的问题。解决净空高度需要将原道路进行下挖处理,而此带来的问题是原道路雨水系统作废无法使用,需要新建泵站来提升排放该下挖部分的道路雨水。本文以苏州娄门下穿道路改造为例,介绍了下穿道路改造时雨水管网如何设计,为以后同类型道路改造提供一定的参考。

With the continuous development of urban road construction, more and more overhead roads were newly built, which are crossed with the existing roads. Therefore, we have the problem of insufficient road clearance in the crossing part. To solve the problem of clearance height, we should excavate the original roads, but it may lead to the problem that the rainwater system of the original road is invalid and cannot be used. We need a new pump station to improve and discharge the rainwater of the excavated part of the road. Taking the reconstruction of Loumen underpass road in Suzhou as an example, this paper introduces how to design the rainwater pipe network during the reconstruction of Underpass road, which provides a certain reference for the reconstruction of the same type of roads in the future.
