EARTH-RETAINING DISPLACEMENT MEASUREMENT SYSTEM, AND EARTH-RETAINING DISPLACEMENT MEASUREMENT METHOD

To provide an earth-retaining displacement measurement system capable of grasping a displacement amount of an earth-retaining material in the middle of excavation, while facilitating installation of a measurement device, and to provide an earth-retaining displacement measurement method.SOLUTION: An earth-retaining displacement measurement system which is applied to an earth-retaining wall construction site where, after inserting a plurality of earth-retaining materials long in the excavation direction in a contour position of a scheduled excavation site, the scheduled excavation site is excavated along the earth-retaining materials includes: a plurality of measurement devices 1 installed at a predetermined depth interval at the earth-retaining materials every time the scheduled excavation site is excavated to predetermined depth, and for measuring an inclination angle of the earth-retaining materials in the installation position and transmitting it wirelessly; and a monitoring device 5 for calculating the displacement amount of the earth-retaining materials in the installation position based on measurement data received from the plurality of measurement devices 1. The monitoring device 5 calculates the displacement amount of the earth-retaining materials in the installation position, based on the measurement data received from the plurality of measurement devices 1 even in the middle of excavation of the scheduled excavation site.SELECTED DRAWING: Figure 1 【課題】 測定装置の設置を容易にしつつ、掘削途中における山留材の変位量を把握可能な山留変位測定システム、及び山留変位測定方法を提供する。【解決手段】 掘削予定地の輪郭位置に掘削方向に長い、複数の山留材を挿入した後、掘削予定地を山留材に沿って掘削する山留壁施工現場に適用される山留変位測定システムであって、掘削予定地を所定深さに掘削するごとに山留材に所定深さ間隔で設置され、設置位置における山留材の傾斜角を測定して無線で送信する複数の測定装置１と、複数の測定装置１から受信した測定データに基づいて、前記設置位置における山留材の変位量を算出する監視装置５とを備え、監視装置５は、掘削予定地の掘削途中においても、複数の測定装置１から受信した測定データに基づいて、前記設置位置における山留材の変位量を算出する。【選択図】図１
