河涌暗涵调查技术分析

Technical Analysis of River Culvert Investigation

地下暗涵作为城市中重要的行洪排水设施,在防治城市内涝方面起着重要作用。在城市化进程不断深入的大背景下,河涌水质污染越来越严重,部分河涌水体富营养化严重,导致水生物大量死亡,水环境改善迫在眉睫。地下河涌暗涵调查是城市河湖水环境整治核心前提之一,也是工程难点所在,更是水环境治理攻坚战中的一块“硬骨头”。

As an important flood drainage facility in the city,underground culverts play an important role in preventing and controlling urban waterlogging.Under the background of the continuous deepening of urbanization,the water pollution of rivers is becoming more and more serious,and some rivers are seriously eutrophicated,which leads to the death of a large number of aquatic organisms.The improvement of water environment is imminent.The investigation of underground rivers and culverts is one of the core prerequisites for urban river and lake water environment improvement,and it is also the difficulty of the project.
