INSTALLATION HEIGHT MANAGEMENT SYSTEM AND INSTALLATION HEIGHT MANAGEMENT METHOD
To provide an installation height management system and an installation height management method with which an installation height of an end member installed at a free end of an overhang part can be automatically calculated, and the installation height of the end member can be managed using the calculated actual value at the time of overhang erection to construct the overhang part to be closed later to become a bridge girder.SOLUTION: The installation height management system comprises: an installation height calculation unit that divides an overhang part into a fixed end side section and a free end side section, and calculates an installation height of an end member on the basis of a bridge surface height of the fixed end side section, an inclination angle to the horizontal of a block included in the free end side section, and an inclination angle to the horizontal of the end member; and an installation height management device that has an installation height comparison unit 614 that compares, for the installation height of the end member, an actual measurement value calculated by the installation height calculation unit and a preset plan value; a first inclinometer installed on the free end side section; a second inclinometer installed on the end member; a target installed on the fixed end side section; and a total station installed on a column head.SELECTED DRAWING: Figure 3
【課題】後に閉合されて橋桁となる張出し部を施工する張出し架設時において、張出し部の自由端に設置される端部部材の設置高さを自動算出でき、また、算出した実測値を用いて端部部材の設置高さを管理することの可能な、設置高さ管理システムおよび設置高さ管理方法を提供する。【解決手段】張出し部を固定端側区画と自由端側区画に区割りし、固定端側区画の橋面高さ、自由端側区画に含まれるブロックの水平に対する傾斜角、および端部部材の水平に対する傾斜角に基づいて、端部部材の設置高さを算出する設置高さ算出部、および、端部部材の設置高さについて、設置高さ算出部にて算出された実測値と予め設定した計画値とを比較する設置高さ比較部６１４を有する設置高さ管理装置と、自由端側区画に設置される第１の傾斜計、端部部材に設置される第２の傾斜計、固定端側区画に設置されるターゲット、柱頭部に据え付けられるトータルステーション、を備える。【選択図】図３
