摘要
为确定区间废水泵房的排水方式以及合理的选择水泵,本文对轨道交通隧道区间的2种排水方案进行了对比,同时对多台排水泵并联运行的工况进行了校核,得出如下结论:1)隧道区间的排水泵房需经过方案对比后选择合理的方案;2)应根据水泵厂家样本资料对单泵工况和双泵工况进行校核,从而选择出合适的水泵,使水泵在单双泵工况下都工作在高效区,而不是简单的进行流量的叠加。
The advantages and disadvantages of two water pumping schemes commonly adopted in running tunnels in ur- ban rail transit works are compared and the parallel operation of several pumps are checked, in order to select rational and feasible waste water drainage scheme. Conclusions drawn are as follows ： 1 ） Appropriate scheme should be selected for the water pumping stations in running tunnels through careful comparison and contrast; 2） The single-pump operation mode and the double-pump operation mode should be checked according to the data provided by the pump manufacturer so as to select appropriate pumps so that the pumps can work with high efficiency, whether .in single-pump mode or in double-pump mode.
