某快速路附属雨水地道泵站工程设计案例分析

Study on Design Case of Auxiliary Rainwater Tunnel Pumping Station Project of an Expressway

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。关键词： 雨水地道泵站；U型槽；暴雨强度；径流系数；连篦；盲沟管；预应力钢筋混凝土管；UPVC管

Abstract:

By analyzing the black and odorous water body of Zhaowei in Chizhou, Anhui, the technical scheme of multi-technology comprehensive application is put forward. The main technical route of "exogenous emissions reduction, endogenous desilting, water quality purification and ecological restoration" is used, and the technical measures of sewage interception, sponge reconstruction, sludge desilting, hydrodynamic force enhancing and ecological restoration are systematically taken to treat the black and odorous water body of Zhaowei. The impact of extraneous pollutants on water quality can be basically eliminated by the quantitative calculation and verification after treatment. The black and odorous water body of Zhaowei has been basically eliminated after this project is put into operation. The goal of the water ecological restoration and long-clear water is achieved.
