【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 setting form of the waste water pump house for the joint construction of the highway and railway tunnel across the river directly affects the investment and operation safety of the project, and is the key and difficult point of the design. Based on the construction of the tunnel across the river by the highway and railway of Sanyang Road, Wuhan, according to the characteristics of the project, The waste water pump room of highway layer and subway layer is separately set up, and three schemes of setting up waste water pump room of subway layer are put forward, which are external pump room, submersible pump room and camshaft pump house. The influence of civil construction on pump selection is also discussed. In the aspects of maintenance, maintenance and safety, the scheme of internal pump room of cam pump is determined, which makes use of the middle and both sides of the track to form three connected small water pools, and uses cam pump instead of submersible pump as the first class pump. Installing in the first stage pump room beside the track can not only reduce the falling depth of the sink trap, reduce the influence on the shield segment, improve the safety, but also facilitate the routine maintenance of the pump.
