港珠澳大桥珠海口岸雨水排水设计解析

Analysis of rainwater drainage design for Zhuhai port of Hong Kong-Zhuhai-Macao bridge

港珠澳大桥珠海口岸工程是举世瞩目的粤、港、澳三地大型跨界衔接工程--港珠澳大桥的重要配套项目。由于口岸建造在海上人工岛上,地基条件差,珠海地处台风频发地区,如何解决口岸核心区重点建筑群内管道的不均匀沉降问题、大屋面雨水排水问题、地下室广场防涝问题,是本项目雨水排水设计需要解决的重点和难点。以问题为导向,通过对于上述问题和技术难点进行解析,设计了一系列措施加以应对。

The Zhuhai Port Project of the Hong Kong-Zhuhai-Macao Bridge is an important supporting project for the Hong Kong-Zhuhai-Macao bridge,The bridge is a large-scale crossborder connecting project between Guangdong.Hong Kong and Macao.Because the port was built on an artificial island on the sea,the foundation conditions are poor,and Zhuhai is located at a region of typhoon happen frequently,how to solve the problem of uneven settlement of pipelines in key core buildings of the port,the problem of rainwater drainage in large roofs,and the prevent waterlogging problem in basement squares are the key points and difficulties to be solved in the design of rainwater drainage in this project.Guided by the problem,through the analysis of the above problems and technical difficulties,a series of measures were designed to deal with.
