青岛胶州湾海下城市道路隧道排水设计思路介绍

Introduction of Qingdao Jiaozhou bay urban road subsea tunnel drainage system design

随着我国城市交通发展,海下城市道路隧道越来越多,其中隧道排水日益重要。结合青岛胶州湾海下城市道路隧道工程,通过对其排水设计思路的介绍,提出了海下城市道路隧道排水设计的一些看法,如矿爆法施工隧道废水排水量的确定、废水泵房位置的选择、水泵及泵房的重要设计参数的优化等,使排水工程投资省、运行成本低且安全可靠。

With the development of China＇ s urban transportation, the subsea tunnel roads are growing more and more, which made the drainage system in tunnel more and more impor rant. Based on the Qingdao Jiaozhou bay subsea tunnel project and the introduction of its drainage system design thought, this paper put forward some views on drainage system design of urban road subsea tunnel. These views included the determination of the volume of wastewater with mine tun- neling method, the locating of the pump station, optimizing the important design parameters of pump and pump station, which were supposed to reduce the project investment and the operation cost of the drainage system and make it safe and reliable.
