摘　　要：地道雨水的积水问题是城市积水问题的主要成因之一。对其汇聚的雨水进行收集和排放的最理想方式是在合理的可征用土地范围内建造单独使用功能的地道雨水泵站,并同时在周边寻找到可以有效收纳其排放雨水的相关河道。本工程的实施为当地新建快速路下穿涵洞的雨水及其周边地下水提供了为其服务的雨水地道泵站的建设思路。同时其泵站庭院内部各类给排水管线的实施及其上下游出路的选择也是本工程值得借鉴的因素。The accumulation of rainwater in a tunnel is one of the main urban waterlogging problems.The most ideal way to collect and discharge its accumulated rainwater is to build a tunnel rainwater pumping station with a separate function within a reasonable range of available land.In the meantime,the relevant rivers are found in the surrounding area that can effectively receive its discharged rainwater discharged.The implementation of this project provides the construction ideas of the rainwater tunnel pumping station for the rainwater and the surrounding groundwater through culvert under the local newly built expressway.Furthermore,the implementation of various water supply and drainage pipelines in the courtyard of the pumping station and the choice of its upstream and downstream outlets is also a worth learning factor in this project.
