TRACK ROADBED MEASURING SYSTEM
To provide a track roadbed measuring system capable of simply and safely checking the degree of formation of a roadbed concrete surface and specifying a position, depth, and range needed for polishing repair in constructing a track slab on the roadbed concrete, thereby making it possible to drastically shorten a cost and time for the construction of the track slab.SOLUTION: There is provided a track roadbed measuring system in which design coordinates 51, 52, 53, 54 in a design stage are obtained for a track slab construction surface 50a of roadbed concrete where the track slab is constructed, and a target gradient in the design is calculated for the track slab construction surface 50a. For a height h of a first pin 40a of a first projection 40 which is a measurement reference point, it is set in advance so as to correspond to a depth D of the track slab. Moreover, a virtual track slab upper surface 50b having the target gradient and passing through the position of the first pin 40a is taken to be a reference surface in the measurement of difference in altitude of the track slab construction surface 50a.SELECTED DRAWING: Figure 4
【課題】軌道スラブを路盤コンクリート上に設置する作業において、路盤コンクリート表面の出来具合のチェック並びに研磨補修が必要となる位置・深さ・範囲を簡易的かつ安全に特定し、これにより軌道スラブ設置作業にかかるコスト及び時間を大幅に短縮することを可能にする軌道用路盤計測システムを提供する。【解決手段】軌道スラブが設置される路盤コンクリートの軌道スラブ設置面５０ａについて設計段階における設計座標５１,５２,５３,５４を取得し、軌道スラブ設置面５０ａについての設計上の目標勾配を算出する。計測の基準点である第１突起４０の第１ピン４０ａの高さｈについては、軌道スラブの深さＤに相当するように予め設定する。そして、目標勾配を有し第１ピン４０ａの位置を通る仮想軌道スラブ上面５０ｂを、軌道スラブ設置面５０ａの標高差の計測における基準面とする。【選択図】図４
