Provided in the present invention are an apparatus for measuring the ground settlement of a ballastless track, and a constructing method thereof, which are not influenced by concrete or asphalt deposition and a precast concrete track application by measuring ground settlement occurring in a settlement plate with a displacement meter buried under the ground, and can solve problems generated by outside exposure. The apparatus for measuring the ground settlement of a ballastless track forms the track lower part structure of concrete or asphalt, and has roadbed concrete, a sleeper, and rails formed on a solum. The apparatus for measuring the ground settlement of a ballastless track comprises: a bottom fixating plate which is installed in a stable layer on the bottom of the solum where a ballastless track is to be installed; a settlement rod which is fastened in the upper part of the bottom fixating plate in a vertical direction; a settlement plate which is buried inside a solum, and settles by penetrating the settlement rod inside the solum by corresponding to the ground settlement of the ballastless track; and a displacement meter which measures the ground settlement of the settlement plate by being fastened to the settlement rod. The displacement meter measures the settlement of the settlement plate while being buried inside the solum, and also includes a settlement rod angle regulating unit which is fastened to the bottom fixating place in order to regulate the angle so that the settlement rod can be maintained in a vertical state. |
