摘要
城市轨道交通地下线在建设及运营过程中,难免存在结构渗漏水、冲洗废水排放等问题。积水过多易引起道床病害、减少道床寿命、影响转辙机正常工作、威胁列车正常运营。及时有效地将废水排出,对轨道系统、隧道结构以及相关设备的维护至关重要。针对道床积水问题,通过调研国内已运营线路,结合地下线轨行区既有排水方案,提出了区间、车站废水泵房处、道岔转辙机基坑及浮置板道床的排水优化措施,解决了轨行区积水问题。
During the construction and operation of urban rail transit underground lines,there are many unavoidable problems such as structural leakage and wastewater flushing,etc.Too much water is liable to cause monolithic roadbed diseases,reduce the life of monolithic roadbed,affect the normal work of switch machine and threaten the train normal operation.Discharge the water timely and effectively is of great significance to track system,tunnel structure and maintenance of the related equipment.Aiming at the problem of ballast water accumulation,the operating lines in China are investigated,and combined with the existing drainage schemes for underground lines,improvement measures for station wastewater pumping,section wastewater pumping,switch machine foundation pit and floating slab drainage are proposed,in order to solve the problem of water accumulation in track area.
