摘要:

公铁合建越江隧道废水泵房的设置形式直接影响工程的投资和运营安全,是设计的重点和难点。以武汉三阳路公铁合建越江隧道为依托,根据工程特点,将公路层和地铁层的废水泵房分开设置,提出设置体外泵房、选用潜水泵的体内泵房和选用凸轮泵的体内泵房3种地铁层废水泵房设置方案,并从土建影响、水泵选型、检修维护及安全性等方面进行综合比选,最终确定选用凸轮泵的体内泵房方案。该方案利用轨道中间及两侧空间做成3个连通的小集水池,采用凸轮泵代替潜水泵作为一级泵,安装在轨道旁的一级泵房内,不仅能减少下沉集水坑的落深,降低对盾构管片的影响,提高安全性,而且便于水泵的日常检修维护。

Abstract:

The layout of wastewater pump room of rivercrossing highway and Metro integrated tunnel directly affects the engineering investment and operation safety. The wastewater pump room of highway tunnel and that of Metro tunnel of Yangtze Rivercrossing highway and Metro integrated tunnel are set separately. The layout schemes of wastewater pump room, i.e. pump room outside tunnel, pump room with submersible pump inside tunnel and pump room with lobe pump inside tunnel, are proposed and comprehensively compared in terms of civil engineering influence, pump type selection, inspection and maintenance and safety. The layout scheme of pump room with lobe pump inside tunnel is selected. The 3 collecting basins are set on side of and in the middle of railway; and the lobe pump is taken as Grade 1 pump on Grade 1 pump room. The adopted scheme can reduce the drop depth of sinking collecting basin and the influence on segment, improve the safety and make the daily inspection and maintenance of pump more convenient.

Key words: highway and Metro integrated tunnel, Yangtze Rivercrossing tunnel, drainage system design, wastewater pump room, lobe pump, submersible pump
