摘要
随着城市各个模块的不断更新与开发,城市地下渠道在城市防洪排涝中发挥着作用日益重要,但也存在诸多问题。深圳市笔架山河历经数次河道渠化、盖板加设和箱涵段改造,暗渠覆盖率约90%以上,但河道运行年久失修,安全隐患多,治理难度大,其除排泄上游水库下泄弃水外,还承担着区间城市排水功能。以笔架山河暗渠暗涵作为研究对象,通过对其日常维护检测情况进行梳理,对该工程暗渠暗涵区域247处缺陷点(段)进行统计分类,查明并分析病害成因,有针对性地治理修复,消除结构隐患,确保工程在后续运行中发挥持续效益。
With the continuous renewal and development of the various modules of the city,urban underground channels playing an important role in urban flood control and drainage,but there are also many problems.The Bijiashan River in Shenzhen has undergone several river channelisation,capping and box culvert section renovation projects,with a culvert coverage of about 90%or more,but the river is in disrepair,with many safety hazards and difficult to manage,and it also undertakes the function of inter-district urban drainage in addition to discharging the downstream flow of the reservoir.In this paper,we take the culvert culvert of Bijiashan River as the object of study,through sorting out the inspection situation in its daily maintenance,and statistically classify 247 defective points(sections)in the culvert culvert area of the project,identify and analyse the causes of the diseases,carry out targeted treatment and repair,eliminate the structural hidden dangers,and ensure that the project will play a long-lasting benefit in the subsequent operation.
