ROADBED RESISTANCE MEASURING DEVICE AND ROADBED RESISTANCE MEASURING METHOD
PROBLEM TO BE SOLVED: To realize a roadbed resistance measuring device and a roadbed resistance measuring method capable of further easily measuring roadbed resistance of a sleeper.SOLUTION: A roadbed resistance measuring device 100 comprises a sleeper cover 30 having a resistance measuring plate 31 of the substantially same size as an end surface Se of a sleeper S, and the sleeper cover 30 is pushed out by a hydraulic jack 40 in the direction for separating from a baseplate 10 in a state of inserting its resistance measuring plate 31 between the end surface Se of the sleeper S and a roadbed B, and a load when moving its sleeper cover 30 by a predetermined quantity in the direction for separating from the sleeper S, is measured by a load cell 50, so that roadbed resistance of acting on the end surface Se of the sleeper S can be measured. Thus, since the roadbed resistance measuring device 100 can measure the roadbed resistance while fastening a rail R to the sleeper S, the roadbed resistance of the sleeper can be further easily measured more than measurement of roadbed lateral resistance executed by releasing fastening of the rail R and the sleeper S.SELECTED DRAWING: Figure 1
【課題】より容易に枕木の道床抵抗を測定することができる道床抵抗測定装置及び道床抵抗測定方法を実現する。【解決手段】道床抵抗測定装置１００は、枕木Ｓの端面Ｓｅと略同じサイズの抵抗測定板３１を有する枕木カバー３０を備えており、その抵抗測定板３１が枕木Ｓの端面Ｓｅと道床Ｂの間に挿し込まれている状態で、枕木カバー３０をベース板１０から離間する方向に油圧ジャッキ４０で押し出して、その枕木カバー３０を枕木Ｓから離間させる方向に所定量移動させた際の荷重をロードセル５０で計測することで、枕木Ｓの端面Ｓｅに作用する道床抵抗を測定することを可能にした。このように道床抵抗測定装置１００は、レールＲを枕木Ｓに締結したまま道床抵抗を測定することができるので、レールＲと枕木Ｓの締結を解除して行う道床横抵抗の測定に比べ、より容易に枕木の道床抵抗を測定することができる。【選択図】図１
