摘要
道岔转辙机是地铁信号系统重要的基础设备。转辙机基坑积水问题由来已久,是目前地铁运营维护中存在的突出问题,长期以来对地铁运营管理和维护带来极大影响,危及行车安全。通过对基坑积水成因、工程实施现状的分析,提出未来可能且有效的整治解决方案。目前,除木塞方案具备工程实践外,止回阀和集水井方案尚处在专题研究和工程化设计阶段,但不失为能实现基坑自动排水功能的理想思路。
Switch machine is a basic quipment in metro sig- nal system, while the hydrops in metro switch machine foundation pit is a long-standing problem,which greatly in- fluences the operation and maintenance process in metro operational management and threatens the operation safe- ty. Through analyzing the causes and the practical construc- tion of the foundation pit, some effective solutions are put forward, except the already used wood stopper scheme, check valve and sump well schemes in research are in the stage of research and design, which are expected to become the ideal solution for switch machine foundation pit hy- drops.
