RESTORATION WORK MAT FOR DERAILED ROLLING STOCK
To provide a mat that can create a flat horizontal surface for supporting a jack when jacking up a derailed rolling stock, and also is hardly to generate fracture due to ballast, and further light-weight and convenient to carry.SOLUTION: A mat 1 is composed of particulate matter with flowability and a bag that is filled with the particulate matter and changes its shape due to particulate matter flow, and the bag is constituted so as to have strength not to generate fracture due to a load when a jack 6 pushes up a vehicle body 7 and is also constituted so that a thickness of a place corresponding to a recessed part is increased due to moving of the particulate matter to the place corresponding to the recessed part of ballast B and so that a top surface is flatted due to decreasing of a thickness of a place corresponding to a convex part caused by moving of the particulate matter from the place corresponding to the convex part of the ballast B.SELECTED DRAWING: Figure 3
【課題】脱線した車両をジャッキアップする際にジャッキを支持する平坦水平面を創出でき、しかも砕石による破断が生じにくく、また軽量で持ち運びに便利なマットを提供する。【解決手段】流動性のある粉粒体と、粉粒体が充填されかつ粉粒体の流動によって形状が変化する袋とからなり、袋はジャッキ６が車体７を押し上げた場合の荷重によって破断の生じない強度に構成されるとともに、バラストＢの凹部に対応する箇所に粉粒体が移動して凹部に対応する箇所の厚さが厚くなり、かつ、バラストＢの凸部に対応する箇所から粉粒体が移動して凸部に対応する箇所の厚さが薄くなることにより上面が平坦化するように構成されているマット１。【選択図】図３
