解决轨道交通转辙机基坑积水问题的设计思路

Design Idea of Solving Problem of Water Accumulation in Foundation Pit of Rail Transit Switch Machine

转辙机是重要的基础信号设备之一,用于操作道岔的转换和锁闭,直接关系行车安全。转辙机基坑积水问题一直是轨道交通工程普遍存在的棘手问题之一,必须加以重视。通过剖析问题的源头,提出从设计阶段初期就应着手进行专业间的接口配合,针对不同的情况选择可行的施工方案。

Switching machine is one of the important basic signal equipment,which is used to switch and lock the point,and directly related to safety operation.The problem of water accumulation in foundation pit of switch machine has always been one of the thorny problems in rail transit engineering,which must be paid attention to.By analyzing the source of the problem,this paper puts forward that the interface between specialties shall be carried out from the beginning of the design stage,and the feasible construction scheme shall be selected according to diff erent conditions.
