Proving Tests for Countermeasures Against Localized Torrential Downpours at Stationhouses

Localized torrential downpours have been tending to increase in recent years, notably in the greater Tokyo area. And, at JR East station facilities, there are many instances now where overflows from such downpours lead to guttering leakages, which inconvenience passengers and cause damage such as malfunctioning of railroad equipment. Urgent action needs to be taken particularly with regard to sheds sheltering passengers on platforms, one of the railway station areas most adversely affected in terms of safety and service. The authors researched trends of localized torrential downpours in recent years together with the current status of leak damage in JR East platform sheds and the configurations of guttering at stations. And, by looking at the load area sizes of sheds and guttering configurations, the authors devised a way of finding drain water disposal capacities and potential for overflow by amount of rainfall, which enabled the authors to show which drainpipe configurations raise the risk of overflow and which ones drain away water smoothly. By making use of this discovery in design of guttering and the approach to maintenance, the authors have been able to pinpoint locations with risk of overflowing during localized torrential downpours; as a result, the authors are now able to take effective action.
