Title:
ROADBED RESISTANCE MEASURING DEVICE AND ROADBED RESISTANCE MEASURING METHOD
Document Type and Number:
Japanese Patent JP2018003483
Kind Code:
A
Abstract:
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
