地下空間の浸水対策としての樹脂製止水板の有効性に関する研究

Abstract

Sandbags, flood board made with wood, metal or synthetic resin are used to protect underground inundation caused by heavy rainfalls. To prevent the intrusion into underground spaces during pluvial flooding, quick and easy set -up of flood protection tools is important. It is need to set these tools as soon as possible. In this paper, the effectiveness of flood protection tools is discussed on the basis of experimental results by using sandbags and two kinds of flood board. Set-up time, volume of water leak and deformation were measured in the cases of still and running water conditions. From the results, it is found that a flood board made with synthetic resin is easy to set up in a short time and the volume of water leak is negligible.
